Hal Leonard Releases The Definitive Guide To Electric Guitar Tone By Dave Hunter

The book and examines how different pieces of equipment contribute to superior or inferior tone.

Hal Leonard Books is pleased to announce the availability of the Tone Manual ($24.99) by guitar author Dave Hunter, who takes on arguably the most discussed topic of gear-obsessed guitarists: tone.

In the Tone Manual, Hunter breaks down the individual components of the electric guitar rig - guitar, amplifier, speakers, cabinets, effects and peripherals - and examines how each piece of equipment contributes to superior or inferior sound.

He offers tips on improving and making the most of the gear you’ve already got – all with reference to interviews with name artists and manufacturers.

In addition, the Tone Manual discusses the evolution of the guitarist’s concept of “good tone”.

It provides an extensive guide to recorded examples of playing generally considered “tonally superior,” citing examples from the early days of electric jazz, blues, country, and rock and roll; from the classic rock, blues rock, and heavy rock heyday of the late 1960s and early ‘70s; and from myriad contemporary artists.

Throughout the Tone Manual, a series of more than 30 “Tone Tips” will offer quick, digestible, practical info bites to help readers improve their sound and better understand their equipment. The Tone Manual also includes helpful diagrams and a cover-mounted CD.

Harrison Launches The New 950m Analog Console At NAB 2011

The feature set of the 950m is geared to meet the unique requirements of a DAW-based studio.

After a decade focusing on digital consoles, Harrison is proud to introduce a new pure-analog console for music capture and mixdown: the Harrison 950m Analog Console. 

The 950m incorporates nearly 40 years of analog innovations and refinement starting with the 32-Series in 1975 and continuing through the 80s, 90s, and into the 2000’s. 

The feature set of the 950m is geared to meet the unique requirements of a DAW-based studio.  It provides all the features necessary to link professionals on both sides of the control room window while delivering the “classic sound” so often sought.

The 950m’s analog circuitry draws directly from Harrison’s legendary musical heritage.  Built like a Large Format Console, but with a refined featureset for today’s studio, the 950m incorporates a massive linear power supply, robust ground plane design, all balanced connections, gold-plated switches, through-hole components, and high-headroom summing busses.

Two separate mix busses (one Transformer-balanced and one Electronically-balanced) - both with built-in compressors and patch inserts - allow for flexible tone-shaping.  For each input strip, a choice of Mono Mic/Line or Stereo Line module is available.  Customer-configured modular construction allows the 950m to operate as a tracking studio front-end, or an analog summing platform, or both simultaneously. 

Input modules provide an Insert point, Switchable HP/LP filters, 3-band Tone controls, Pan/Balance, Trim, Input switching, 4 Mono Aux sends, Mute, Solo, 104mm Fader, and 4-segment Meter. 

Microphone channels also have a 48v phantom-power switch and a post-fader Direct Output.  The Mix Master module includes 2 Stereo Mix Bus compressors, Oscillator/Talkback Assignments, Aux Send Masters, and 104mm faders for each of the two stereo Mix Busses. 

The Monitor module includes the Oscillator controls (100Hz, 1kHz, 10kHz), Monitor source selection, Monitor Level/Mute/Mono, Talkback, and Headphone jack.  The Studio module includes source Selection/Level/Mute/Mono for each of the 2 studio feeds, as well as Talkback assignments.  The Output module houses the output transformers and 2 stereo Mix Bus VU output meters.

A quality analog mixing console is a significant long-term investment for any studio, and it is important to choose wisely.  Engineers at Harrison picked the most reliable, best sounding analog components from their most successful consoles - many of which are still in daily use decades later. 

Accommodation is made for future expansion options via modular construction and fader VCA bus connections.

For today’s DAW studio, Harrison designed a frame providing a deep 2-tiered front bolster to accommodate a keyboard, mouse, and DAW controller. 

The straightforward controls on the 950m provide the necessary analog sweetening circuits while remaining easy to recall.  The 950m is offered as a stand-alone console or paired with Harrison’s premium console converters, providing a practically unlimited number of I/O - using either MADI or gigabit Ethernet. 

Key features:
• Professional-quality modular design
• Mono and stereo input modules
• HP/LP filters, Tone controls, and 4 Aux Sends
• 2 separate Mix Buses with built-in compressors
• “Red” Transformer-balanced Mix Bus
• “Black” Electronically-balanced Mix Bus
• 2 Studio feeds with Talkback
• Separate Linear Power Supply
• DAW-friendly desktop frame

The Masters of Bass

A unique audio design for world-class anglers.

The Bassmaster Classic is not about subwoofers, as some readers may be thinking, but rather is a professional bass fishing competition, and in fact, the winner of this annual tournament is widely considered to be the world champion of the sport.

The first classic was first held in 1971 on Lake Meade, NV, and over time it has grown into a compelling spectacle.

Each year in late winter, the top bass anglers converge on a pre-selected U.S. site for three days of fishing, with each day followed by a theatrical presentation of the weigh-ins.

The event is organized by the Bass Anglers Sportsman Society (BASS), which was acquired in the fall of 2010 by Jerry McKinnis, Jim Copeland, and Don Logan, continuing a long-standing media relationship with ESPN, which provides hours of television coverage.

This year’s contest, held in February on the Louisiana Delta, featured a field of 50 anglers, with the nightly weigh-ins presented at the 19,000-seat New Orleans Arena, adjacent to the Superdome in the city’s central business district.

These festivities were outfitted with complete production, including concert-level sound reinforcement for the entire arena, by Reel Rock Productions and its sister company, Production Support Group (PSG).

The QSC WideLine line array sets – mains and out fills - flown high above the stage.

Founded in 1980 by Larry Schmidt and based in Tallahassee, FL, the companies have steadily grown to provide full production services to a wide variety of clientele throughout the continental U.S.

This was the first time out with the Bassmasters Classic for Reel Rock/PSG, with Schmidt noting that the organizers were seeking a different direction than the past with regard to production.

A bass fisherman himself, Schmidt presented some creative, relevant ideas, and his companies were awarded the project last summer, with planning for this year’s event commencing shortly after for total turnkey production – staging, lighting, video, special effects and sound reinforcement.

Considerable Attention
“A key aspect to understand with a project of this nature is that it is a TV show first, so you have to treat it that way,” explains Schmidt, who served as the event’s production manager.

“All of the production elements have to take this into account, and with respect to sound, it has to be invisible, because camera sightlines and a clean broadcast picture are paramount.”

However, there is also the matter of providing commensurate concert-level sound reinforcement for the thousands in attendance at the venue each evening, and it was an aspect that garnered considerable attention from the Reel Rock Productions sound team - Dennis Cooper, Ed Vertuno, and Jim Apgar - a veteran group who’s most “junior” member has 25 years of experience.

The highlight of each night’s show had every contestant aboard his boat, towed into the arena to the stage via pickup truck for the weigh-in of his catch that day.

This meant 50 weighins on each of the first two nights, and 25 as the field was narrowed on the final night, each only about two and a half minutes apart.

To streamline this parade, the stage was angled so that upon entering the arena, the trucks had a straight path – but it meant that the stage was angled 45 degrees from a typical “square” placement. The result was a challenging coverage situation.

“There was definitely some unusual geometry, particularly in contrast to a typical concert situation in an arena,” Schmidt notes.

The sound team for the Bassmaster Classic at the Yamaha PM5D house console (left to right): Brian English, Larry Schmidt, Dennis Cooper, Ed Vertuno, and Jim Apgar.

“However, we determined that a left and right flown array configuration was still the correct approach, even though the arrays would have to be placed differently than usual and the delivery times between the two sides would differ greatly.

“In addition, and this comes out very clearly when you look at in drawing form, you see that the stage right array would actually be covering more of the room than the stage left array,” he adds.

The team performed initial plotting of array location and coverage, and then added an out fill array to each side as well to fill any potential gaps, particularly on the extreme sides of the coverage area.

Just Right
Schmidt also discussed the situation with his long-time colleague and friend Brian English, director of concert system solutions for QSC Audio and a veteran of many unique sound reinforcement situations, to get his input as well.

And in fact, English decided to venture to New Orleans at the outset of the production load-in to collaborate with Schmidt on the system programming and deployment.

CAD drawings helped form the primary layout and positioning well ahead of time, and then once on site, the team did a lot of adjustment and optimization of the arrays to get things just right.

The Rational Acoustics Smaart platform also proved particularly helpful in synchronizing the various time arrivals.

A Real Asset
A staple of the Reel Rock Productions sound inventory is QSC Audio Wide- Line line arrays, which provide very wide 140-degree horizontal dispersion that proved to be a real asset, particularly given the coverage challenges.

Main left and right arrays were each comprised of 16 WideLine-10 modules (dual 10-in, single 1.4-in-exit compression driver), with the bottom portion of each array in a “spiral” configuration to bolster coverage to the very front seats without the need for front fills that would have hampered the stage aesthetic.

The out fill arrays, flown to the sides of the main arrays, were each comprised of eight QSC WideLine-8 modules (dual 8-in, single 1.4-in-exit compression driver).

All of the WideLine models are equipped with a simple 3-point rigging system that allows fast, precise construction of arrays of up to 24 enclosures.

“We keep our WideLines very busy,” Schmidt notes. “They’ve proven to handle all sorts of events quite well. They are perfect for a building block approach – 8 boxes a side, 16 a side, 20 a side, whatever is needed for a given project, and with 140 degrees, you can get a lot done.

Nine racks of QSC PowerLight amplifiers networked via QSControl.net.

It’s very modular, and we tailor the companion amplifier racks to match. It’s quick and clean, fits well within trucks, and it’s all topped by exceptional fidelity.”

This array set was able to cover the entire arena, from top to bottom and side to side, and it was driven by nine racks of amplification that resided behind the stage. The mains were powered by QSC PowerLight PL230 amplifiers, with PL380s amps for the out fills. Everything was driven in bridged mode except the compression drivers. Array height topped out at about 55 feet, well out of sightlines.

Zero Point
The low-frequency portion of the system presented another challenge – there wasn’t a “good” place to put the subwoofers. Schmidt, English, and Cooper implemented a rather novel approach – the system’s eight EAW SB1000 subs (dual 18-in) would be positioned in a stack within a video LED panel at the stage (also driven by PL380 amps).

It was a method they’d utilized on select smaller scale events, and it worked out here as well.

Interestingly, given their positioning at the stage, the subs also served as the system’s “zero point” with respect to timing. In other words, all other loudspeakers were timed in relation to the output of the sub stack, and to further bolster lower frequencies, the main WideLine arrays were run down to 60 Hz.

The end result was truly dynamic output, yet with a high degree of coherence that was free of “rumble.”

The entirely digital signal path from the Yamaha PM5D console at front of house to the backstage racks utilized the QSControl.net networked audio platform. A QSC RAVE 522ua fed nine QSC BASIS 914 and 922 digital processors, with distribution via Cat-5 and overall control with QSC Venue Manager software.

“With the networkable control of the amplifiers, it’s great - all right there, both loudspeaker and overall system processing,” Schmidt says.

“It’s a very powerful package. Take your left and right sends off the desk, put it into RAVE, and then everything is controlled off the network. It’s simple, slick and extremely effective.”

A 360 System Instant Replay machine provided all recorded music tracks for the show, fed directly into the PM5D. Vertuno supplied all vocal mixes, while Cooper handled the music.

Backstage, Apgar stayed very busy as the “mic wrangler,” coordinating the hand-off of Shure UR-4D wireless microphone transmitters to each announcer as the boats approached the stage, in addition to managing more wireless microphones for various MCs and other “talking heads” on stage.

Loud Enough
Saturday night presented an added wrinkle, with country performer Randy Montana and his band performing prior to the weigh-in.

They were provided with a hard-wired microphone package and DIs, as well as QSC K10 and K12 self-powered loudspeakers for monitoring and fill, with about three minutes allotted after their performance to clear the stage.

For Reel Rock Productions/PSG, this initial experience with the Bassmaster Classic proved a success, despite it being their first time serving the event combined with the unique challenges.

“One particularly fun moment was when the client first saw the arrays, and asked if they’d be loud enough,” Schmidt concludes. “I pushed up the main fader, the system absolutely filled the room with full and intelligible sound, and all doubts were erased.

“I have high expectations for everything we do, and I feel we hit the mark. The system performed admirably, we have a happy client, and that’s the whole point.”

What Is Music Production: Understanding Sessions & Content Creation

An excerpt from Golding and Hepworth-Sawyer's book which takes a look at the creative side of sessions.
This excerpt provided by Focal Press

This is the first segment in our series by Golding and Hepworth-Sawyer on audio production. Additional segments are available here.

Confident creation
The studio session can be one of the most exciting times in the creation of a project, where the fruits of pre-production can begin to be seen and where musical spontaneity can create a very special result.

The recording session is the stage where everything seems to happen, certainly in a capture sense. Artists, bands, session musicians, engineers, and producers all combine under one roof to create.

It is the point in the project where ideas become a reality and a “product” starts its life. The fact that the ideas and spontaneous moments become “committed to tape” at this stage can be an issue for some and this can often lead to tense and nervous environments in which to try to be creative.

Being able to create and inspire confidence within the recording session is a skill that all producers need to have in one guise or another. Once established in the industry, many producers may take this as a given; however, when first starting out down the rocky road of music production, the topic of creating and inspiring confidence may be a difficult one to grapple with.

So what do we mean by “confident creation”? One of the key factors here is believing in what you are doing. There’s no good in being involved with a project for which you lack enthusiasm and vision, as this will hinder your abilities to steer the project and inspire confidence in others.

It is sometimes surprising how saying nothing can be the loudest form of communication and, in the relative confines of a recording studio, body language can say an awful lot as to the true thoughts and feelings of the individuals involved.

This lack of enthusiasm and vision can occur for a variety of reasons, but many times it can be down to the fact that you simply do not really understand the project and therefore don’t believe in it. When we say “believe” we essentially mean that you are able to see, understand, and agree with the overall artistic vision and musical intentions of the project.

This is where the marriage of artist, project, and producer comes into play and the involvement of the right people for the job is of fundamental importance. Knowing when to accept the invitation to be involved with a recording or not can be a tricky call to make; any doubts need to be ironed out before commencing.

If not, you may find yourself in a very uncomfortable position further down the line when the stakes are considerably higher and you’re performing less confidently.

Your influence needs to be exuded not only to the artist and musicians involved but also to the artist’s management and A&R. It is worth bearing in mind that the artist’s management and A&R from the label are placing a considerable amount of trust in you and your abilities, and in some cases are entrusting their latest talent into your guiding hands.

It is understandable that this can create tension, especially when time, effort, and money are being invested. Therefore, being confident in what you are doing and the decisions you make is important, as many in the process will be looking toward you for a reassuring lead.

Your role?
The producer’s role in the session can, as ever, be one of many things (as we will discuss later in this chapter).

The role has been described in a number of ways before but we tend to think of a chameleon and the way in which it changes its colors in order to blend in with its surroundings.

Likewise the producer’s role in a session is one that will need to change and adapt in reaction to what is required in order to achieve a successful recording.

The need for adaptability has been a common thread in conversations we have had with various producers while writing this book, and it is obvious that different individuals work in differing ways depending on their background, skills and experience.

However, there are a number of generic points that seem pertinent to remember when considering the producer’s role within the recording session.

Firstly, the need to maintain an objective perspective in the studio is of paramount importance. It is the producer’s job not to become too bogged down in the fine detail or emotion but to maintain the vision of the project as a whole.

It is the producer’s responsibility to know when there is some mileage in an idea or when time is possibly being wasted. Secondly, the artist is the most important person in the room.

This is hopefully common sense to most that will read this; however, it is worth acknowledging that once wrapped up in the moment of a session it can become easy to forget the reason why you are there and what it is you are trying to achieve and why.

It is the artist’s and musician’s session. They are there to perform and record; certainly you will have your views and opinions (that is why you have been hired, after all), but your interaction should always be for the good of the artist.

Producer, arranger, and engineer Haydn Bendell describes the role as one of “a service provider” where the artist/musician should always be made to feel as comfortable and safe as possible.

When discussing the importance of the artist, he gives the example of two records he may produce using exactly the same studio, people, equipment, and techniques.

Yet while one record could go on to win various awards, another could be far less successful.

The variable factor, the artist, is surely the most important cog in the machine. An idea worth considering when examining the way in which we all work, perhaps?

There are many ways in which creativity can be inspired and achieved and we know that many producers have a variety of styles and methods (even if they themselves struggle to explain exactly how they do it).

Of course, some would argue that much of the creativity takes place before the recording sessions occur and that after pre-production there is not always time to be experimental and creative.

However, let’s remember that, despite the careful planning and arrangement achieved via the pre-production stage, the recording sessions are more often than not the place where ideas blossom and develop and where great performances can make a real difference to a song. The producer’s role is integral in steering this creative process.

So how do you create a creative environment or engender creativity within a session? As you have by now realized, you will not find a hard and fast answer to this question, no matter who you ask (believe us, we have!).

However, there are considerations and ideas that may be helpful when tackling this issue. Creativity can come from a variety of different sources, some of which are more obvious than others, but in order for a producer to create a creative environment some basic issues need to be realized.

Firstly, for any person to be creative they need to have a sense of security. Therefore, in the context of the session they need to feel comfortable with the people around them.

In order for this to be the case, the people they are working with need to understand them and what makes them tick; a mutual trust needs to be developed.

This may sound rather deep but a producer really needs to put some time into getting to know the artist and musicians they are working with in order for this to take place.

It may sound trite, but a preliminary meeting over a coffee or beer really could help the creativity of a session further down the road.

Secondly, creativity is a very personal thing and usually comes from some kind of emotion. Therefore, creating an environment that someone can feel relaxed (or safe) enough to be emotive in is essential.

An artist or musician needs to feel sure that whatever they do or say in the studio stays in the studio and that they are essentially able to be themselves.

Therefore, it might be worth considering who is around the studio during recording sessions and the space that is used in order to capture a performance.

If you want an intimate and personal performance and delivery, then the live space of Studio 2 at Abbey Road may not be the best place!

Thirdly, think energy! It is difficult to be creative in an atmosphere that lacks energy. There’s nothing worse than trying to be creative and bounce ideas around when something or someone in the session is bringing the vibe down.

By energy and vibe, we mean a sense of positivity or sense of enjoyment.

Certainly we acknowledge that some great and very creative results can come from a negative situation (just consider the personal relationship issues surrounding the Fleetwood Mac Rumours album, for example).

However, in general the recording session should be an enjoyable, positive, and creative experience. If people are not enjoying the process, then the producer needs to identify why and seek to address the issue.

In many ways the initial vibe for the session is created and set by the producer, something which at a later point the artist and musicians will pick up on and feed off of. The producer really needs to have his finger on the pulse of the session.

An interesting psychological perspective and methodology to consider while discussing this topic comes from that of producer Brian Eno.

The Art of Record Production by Richard James Burgess (2005) describes how Eno developed a set of mood cards for use when artists are seemingly at a creative dead-end. These cards pose statements designed to provoke a response of some kind in order to restart or reroute the creative process.

Allowing time and room to experiment can be a very liberating and fruitful approach for both the artist and producer.

Many anecdotes can be told by seasoned professionals whereby experimentation and serendipity has led to a pleasing result.

However, creativity has inherent dangers if left to run wild, and this is where the producer needs to have control over the session and be able to discern a good idea from a bad one. Being able to perceive and judge how a situation is unfolding and what the possible result will be is an essential skill to have.

This is where industry names such as Brian Eno and Trevor Horn have received much praise from artists they have worked with. Not all experimentation leads to the desired outcome, so the producer has a responsibility for quality control as it were, making sure that whatever is being created still fits the overall aim of the session.

This section could quite easily turn into a lesson in psychology (as could many of the sections within this book) but this is not really our aim here.

Therefore, while contemplating the topic of creativity and confident creation we’d suggest considering the following four simple mindsets or approaches, which may prove useful within the studio session.

We’ll call them director, catalyst, nurturer, and psychologist; of course much depends on the situation you find yourself in and as such these mindsets will become interleaved as the sessions take place. Being flexible is key.

All of the approaches above and discussion as to creating a creative environment are generic to all producer roles or types and apply equally, no matter the skill set, knowledge, and expertise.

However, if as an individual you possess the practical and theoretical musical skills, then your creative input during the session can potentially be quite considerable. Your musical ability to play, compose, and arrange will allow you to be a more tangible part of the creative musical process.

This may be as basic as suggesting a slight alteration to the lyrics or the melody, through to playing or arranging and introducing new parts or tracks to the song to further enhance the production.

The fine details of all of this will depend on the nature of the artist or band you may be working with and the way in which you have agreed to work together.

As ever, knowing when and when not to use these skills is important, as some artists or groups may be more independent in these areas than others.

Evaluating A System Budget For House Of Worship Clients

Success often lies in the smallest of details

How do you establish priorities for your operating budget each year? Do you have a five year plan for your ministry, a solid idea of where you want to be in the future, and a way to stay on task?

Do you find yourself constantly putting out fires, using duct tape and tin foil solutions, and never quite hitting the mark?

In preparing to write this article, I enlisted the help of our ChurchSoundcheck Discussion Group. I found their input especially interesting. Here’s a sampling of their comments:

One thing that always seems to be missing from small to medium and even some larger church budgets is a maintenance / emergency / contingency fund. For example, the new IEM system gets put on hold for another year as soon as a dimmer pack fries or a monitor amp goes!

And when was the last time the church had a pro come in and check/reset gain structure, EQ, and do a component check? It is surprising how often a church has a weak amp or blown component in their cluster and do not even realize it.

There are often complaints about the sound and the MoM/Pastor/Techies start talking about upgrades, when what they really need to do is to repair damaged components such as damaged cables, tape machine maintenance, projector and stage light lamps, lavaliers for wireless packs and non-functioning hearing assistance receivers.

The little things can add up to major dollars over the course of a year. I say protect the money set aside for new stuff by having a large enough maintenance budget to get the equipment functioning and keep it there.

Keith Thompson

I’ve just started on my items for the next fiscal year. I always submit a decent list of items. I don’t break them down by need. I just give them my list.

“I do however have the items broken down on my list as follows:

1) Equipment I want
2) Equipment we need but could do without
3) Equipment we should have
4) Last, but not least equipment we must have

“Needless to say, by the time the list goes through the review process I usually end up with some of what we must have.

Rick Dean

We handle all maintenance with a maintenance fund. Money is put into it every month. The current balance is in the area of $25,000. All maintenance costs are taken from it (audio, video, computers, recorders, heating systems, paint, vehicles, etc).

This way we don’t have to budget for maintenance, unused money is carried over from year to year, and we don’t have to go to the board for money every time something needs to be fixed. It’s been working very well.

Bob Lewis

I believe the three most important items are:

1) Capital expenditures for new equipment, equipment replacement/upgrades
2) Repair and Maintenance
3) Supplies: cost of disposables such as audio & video tapes, CDs, MDs, batteries, batteries, and more batteries.

One thing that I think we most overlook is the rental of extra gear for special events. I think that is a major item and should be included but I’m not sure if it’s a separate category or included in one of the above.

These folks have hit it on the head, haven’t they? Based on my own experience, the supplies category gets the most attention. Not that it should be first, but it’s the operational fire that needs to be extinguished each week.

For example, do you ever find yourself driving to church for the services one day only to realize in a panic that you’re out of fresh batteries, which of course has you diving into the nearest gas station with a food mart to grab a couple of incredibly high-priced 9-volt batteries?!

You know what happens. You’ve evaluated the supplies issue and ordered the quantities you think you’ll need for the worship center. But then, right before the service, somebody from the youth ministry rushes up to you begging to “borrow” a couple of 9-volt batteries.

Standing in line behind them is someone from the Children’s Ministry asking for a battery and some gaffers tape. A few minutes into the worship service, someone from the Senior Adults Ministry is tapping you on the shoulder asking to for a cassette/DAT tape.

Sound familiar? Of course, that’s never happened to me, but it’s far better to stay on top of the supplies issue. In fact, in an all-volunteer tech support ministry, I think it’s especially helpful to assign one member of the team to simply manage supplies.

If an aspiring audio team member really doesn’t want to mix, but they are exceptional organizers, then hire them! They can maintain an inventory of the supplies, and be responsible for filling out the purchase orders, placing the orders with the usual suppliers (or running to the local store for those supplies), and keeping everything organized.

To minimize costs try buying in bulk whenever possible. The cost of those batteries and cassette tapes will drop to a dull roar if you can buy them in quantities that will get you through a month or two at a time.

Equally important, you’ll have extra supplies on hand when someone walks up to you on Sunday morning with their hand out.

I couldn’t agree more with Keith Thompson’s urging that churches should pay more attention to the ongoing need for maintenance and repairs. I’ve had similar experiences. I’ve been in two different churches in recent years where the high frequency drivers were blown in all of their main loudspeakers, and yet no one realized it.

All they knew is that it didn’t sound as good as it used to. That’s the time to call in a professional ­ either a consultant or a reputable contractor. Recognize if the item is worth repairing, or if it should simply be replaced instead.

A long time ago I had to get over the idea that an inexpensive cassette deck is simply a supply item. If it costs more to fix it than it does to replace it, just toss it out, buy a new one, and get on with life. I know, it doesn’t seem right to throw something you paid $300 for into a dumpster but, unless you’re a trained repair technician, get used to it.

Rental Gear
There is wisdom in renting the gear you need just on occasion.

For example, a great many churches find themselves in need of extra wireless mics now and then, especially for those Christmas pageants. Some can’t yet afford to install subwoofers, but want to add some extra weight to their sound for their Easter drama pageant.

Extra stage lighting fixtures and special effects devices are good rental items to consider. And who needs to buy a phone hybrid? I can only recall two times in the last 20-plus years of working with churches that I needed to feed the house system with a live phone conversation between someone on stage holding a mic and a missionary overseas talking on a phone. It just makes no sense to buy something like that.

A well-stocked, reasonably priced rental company provides an excellent service for churches with these kinds of occasional equipment needs. It pays to shop around, though. Several years ago I paid as much as $4,000 to rent a few high quality wireless mic systems for several weeks.

A few years ago, I found a company that would rent me the exact same units for the same time period for about $1,400. As you’re filling out your next annual budget, remember to include a line item for general rental needs.

Usually there is a separate budget for major productions. Renting wireless mics for your Christmas pageant, for example, should come out of the Christmas pageant budget, not your annual operating budget.

Capital Expenditures
This is where you put more expensive gear that you know you’re really going to need in the near future. For example, if the FOH mixing desk is really showing its age, and it’s past due for a replacement, be sure that a reasonable price for a suitable replacement is tagged in the church capital budget.

Try to think well into the future. If you can project that high ticket items under your command such as mixing consoles, video projectors, computers, etc. ­ should be replaced within the next five years, then get those items on the capital budget list now.

Let the senior pastor, administrator and especially the finance officer get used to the idea. Give them time to develop a plan that will ensure that the money is there when you say you’re going to need it. Don’t forget to remind them on occasion, and be sure to ask for it when the time comes.

If you don’t, they just might decide that they want to replace the carpet in the foyer instead of buying your new console! Trust me on this.

At one point, my signing power as the Audio Director of a reasonably large church was $500. A couple of years later, they dropped that to $250. At first, I felt insulted. Later, as I thought about it, I realized my diminished purchase authorization was a blessing in disguise.

This meant that any purchases that I needed to make for the sound systems that were over $250 apiece didn’t come out of my $25,000 operating budget. As such, funds for a desperately needed wireless mic didn’t come out of my supplies budget.

Time Is Priceless
I’d like to add one more item to the list, and that is time. I know very few people who aren’t going through this life racing to meet one deadline or another. Not that it’s right, or even good, but certainly common.

Some of those time goals are self-imposed, while much of that activity is directed toward putting out fires that other people have created for us.

People usually want their problems to be your problems, and some are especially good at delegating. I would consider time to be the most valuable category on the list.

Church Sound Files: How Do You Know When It’s The Right Time To Upgrade A System?

A question deserving considerable thought and begging a slew of additional questions before making a decision

In this ever evolving world of more, more, more, better, better, better, when is good enough, good enough? 

Is it really an absolute necessity to update or upgrade my 15-year-old sound system? 

The working life of a sound system can extend well beyond 20 years, and I’ve personally seen systems 30 to 40 years old still in use and functioning quite well.

The question deserves considerable thought, and begs a slew of additional questions:

1. Has your programming changed (added a keyboard, drums, bass……..)?

2. Have you added any additional seating, like additional rows of seats in the front or back?

3. Are you experiencing intermittent problems or shall we say, surprise noises?

4. Has the expectation of your congregation changed?

I not a person who promotes technology for the sake of technology.  However, I do enjoy thinking of myself as “hip” and an early adopter.

In fact I owned the original Palm Pilot, one of the first Windows Mobile PDA’s and a Palm Treo Pro phone all purchased right when they were released. 

Oh yeah, I forgot the Apple Performa 405 PC I purchased in the early 90’s, the iMac, and now the Macbook pro…..  Okay you get it, I love new technology and am not afraid to be one of the early one that jumps in, with some caution. 

I am usually not the first, but reside comfortably in the early pack that makes a purchase. I prefer to wait and see the viability and stability of the product.

So what does my personal love of technology have to do with upgrading your sound system? Not much, other than show that I am not an anti-technology kind of guy.

Getting back to the issue at hand.  I would like to introduce a fifth question.

5. What is the expectation of people who come and visit your church?

Between 1913 and 1920, Thomas Edison did more than 4000 “blind listening tests” to promote his Phonograph equipment and Diamond disc recordings.  Edison would rent theaters and concert halls to do a comparison. 

He would hire some of the prominent musicians of the day and have them behind a curtain. The musician would sing a song and then a recording would be played on the Phonograph. 

Believe it or not the audience could not distinguish any difference between the two. In other words, they could not decipher if it was live or recorded. If you are like me you have to be saying - Hold on! People had to hear the difference between a scratchy, frequency limited recording and a live person. 

I guarantee if we took the exact same equipment and repeated the test today, the majority of people would easily be able to point out what was live and a phonograph recording.

Other than almost 100 years, what is the difference? Reference! What did people in the early 1900’s have with which they could compare the recording? 

Okay, by now I think you get the point.  There are a number of great reasons to upgrade your audio system however, if it’s still in “working order,” then managing and dealing with the expectations of your congregation (also known as questions #4 and #5) are great reasons to update. 

So, how often should a system be updated? Ignoring changes in programming, seating, and any potential issues you may currently be experiencing with your system (do it today if these reasons apply, you are overdue) my answer: if the system is older than your car, it is time to update. 

This is my answer primarily because our family drives a 1998 Suburban and two other late 1990s-vintage vehicles. Maybe a better answer is every time the second number in your age repeats (10 years for those not good with numbers and abstract concepts), it’s probably at least time to begin considering upgrading.

Factory Direct: A Look At The Powersoft Armonía Pro Audio Suite

Advanced power amplifier control software.

Gone are the days when a so-called dumb, brute force power amplifier was the simple connection between front-of-house electronics and the loudspeaker system.

We’re now in the age of the smart amplifier that is both software and audio driven, creating a close marriage between audio control software and the power amplifier.

In short, the power amplifier has now become a technology platform capable of supplanting many other pieces of gear that were stand-alone units like crossovers and room-tuning EQ units.

To meet the challenges of this union, Powersoft has created PC-based Armonía Pro Audio Suite advanced control software to manage its K, Q, D, Duecanali and QTU1400 Series amplifiers.

Armonía provides unique capabilities that allow system engineers to efficiently maximize the interaction between the amplifier and loudspeaker, while providing programmable control of key features like damping, EQ, limiting and crossover.

The full expression of Armonía is available to Powersoft amplifiers equipped with DSP and AESOP (AES3 and Ethernet Simple Open Protocol) cards.

But to develop Armonía, we needed to consider the real-world aspects of designing, implementing and running a sound system for touring or installation.

Back to Bass-ics
Ask any engineer, artist, show producer or audience member about the sound at an event and the bass response is usually at the forefront of comments.

Delivering tight, well defined bass frequencies is of paramount importance to the sonic success of an event. We have incorporated our patented Active DampingControl feature into Armonía for precise tuning of system damping for loudspeakers reproducing frequencies under 400 Hz.

Active DampingControl for maximizing damping parameters.

The value expressed for damping describes the ability of the amplifier to suppress undesirable movement of a cone near the loudspeaker’s resonant frequency.

A loudspeaker’s diaphragm has mass and the cone rigidity, the combination of which forms a resonant system. A loudspeaker also generates electric current from its electromagnetic voice coil moving within the magnetic field of the natural magnet structure.

When audio frequencies are applied to a loudspeaker, excess motion can be generated at or near the resonant frequency. So, the greater the damping number, the more control.

This complex relationship between amplifier and loudspeaker relative to frequency is not the only problem.

The effect of cable resistance on a high power amplifier’s performance also becomes significant at low frequencies, as the cable resistance can affect the output stage’s damping factor. As each installation requires different cable runs, the damping numbers can vary greatly.

Active DampingControl is a proprietary algorithm which compensates for cable resistance. This means cable parameters may be entered in either Metric or American Imperial units for cable run length and wire gauge.

Armonía then sets the cable resistance value and the algorithm calculates and applies the appropriate correction.

System engineers can now precisely tune each different setup based on the physical realities of a particular installation, yielding consistent sonic results from a particular amplifier/loudspeaker combination used over various events.

Impedance, Alive & Well
The LiveImpedance feature for Armonía provides a graphic display of instantaneous load impedance against frequency for each channel. This gives the engineer a constant update on loudspeaker and system performance over time as a function of power transfer.

The instantaneous impedance is calculated from snapshot measurements of output voltage and current.

Real-world amplifier loads like loudspeakers have a complex impedance relationship against frequency and power, which means that the impedance possesses both resistive and reactive components.

Because the components are in quadrature with each other, typically separated in phase by 90 degrees, the impedance has both magnitude and phase.

Both quantities are calculated and displayed by LiveImpedance for constant monitoring by an engineer.

LiveImpedance shows instantaneous load impedance against frequency.

With the understanding that an amplifier’s output stage might be constrained by filter assignments from handling the entire audio frequency spectrum or the audio program may not contain certain frequencies at the instant of snapshot, the display may not be a complete, full spectrum plot at any given moment in time and setup.

We color coded Armonía’s displays to show the magnitude of the impedance in ohms and the phase angle of the load in degrees. The default impedance scale is from 0 to 100 ohms and the default phase scale is ±90 degrees.

The magnitude and phase buttons open drop-down lists of alternatives where the impedance scale may be reset to 0 to 25 or 0 to 50 ohms, and the phase scale to ±180 degrees. While the default impedance scale is linear, a logarithmic alternative may be selected to improve the resolution in the particularly important 1 to 10 ohms range.

Apart from displaying the complex impedance interaction, the LiveImpedance graphs can also display reference data derived from the amplifier’s normal (non-DSP) output impedance measurements and imported “ideal” impedance plots from speaker manufacturers.

All these different graphic representations make the engineer’s task of monitoring high output levels of multiple amplifiers over long periods very simple and further enhance an engineer’s understanding of the relationship between the power amplifier and a particular loudspeaker at a live event.

Limiting Factor
A third complicating factor we needed to address with Armonía in the relationship between the power amplifier and loudspeaker is optimizing power transfer to a speaker.

To accomplish this, the TruePower limiter feature yields controlled operation for longer driver life by maintaining safe output power levels referenced to frequency and true load impedance. Armonía’s power limiter section allows the user to select one of two methods of power calculation: TruePower and Equivalent Power at 8 ohms.

TruePower is the preferred setting to choose when the number of loudspeakers connected to the amplifier channel is a known quantity.

TruePower limiting fosters controlled operation for longer loudspeaker driver life.

It is based on averaging real-time measurements of output voltage and current to define the limiter’s intervention point for power limiting in order to stay within a speaker’s safe operational range.

With this information, Armonía is able to estimate the instantaneous power available at the amplifier terminals. TruePower also features a peak limiting section to cover all the signal bases.

Choosing the Equivalent Power at 8 ohms setting will result in all power calculations being based on an arbitrary 8-ohm load.

The output voltage is still measured and from that information the output current and power can be derived. Working essentially as an RMS voltage limiter, this mode is useful when the number of loudspeakers connected to the amplifier terminal is unknown.

Modeling In Fashion
Armonía also offers an amplifier modeling feature that can address amplifier DSP and routing online or offline.

In offline mode, Armonía lets a systems engineer plan out an intended system of any size at the office (or even on a tour bus or plane) using virtual amplifiers for programming before connecting to a network.

This is very useful to the engineer to match amplifiers with appropriate DSP functions like crossover and EQ to loudspeakers before the system is on the truck. This also gives a clear picture of system resources needed for a particular event.

When used in online mode, system information can be sent or retrieved from the synchronized network. From here it is possible to copy an amplifier’s presets to the PC running Armonía and vice versa, including the very useful option of copying a set of presets to multiple amplifiers simultaneously.

All parameters designed in offline mode can be sent to the online actual amplifiers and, when used with the optional Powersoft Ethernet KAESOP board, a system engineer can extend the network to a virtually unlimited number of amplifiers through either auto-addressing with self-assigned IP addresses or end-user configurable IP addresses.

Making The Connection
Armonía is an Ethernet-based software package that offers full control of all amplifier parameters while accommodating AES3 audio on the same cable.

The software has built-in redundancy and extensive logging and alerting features designed to provide worry free operation for the sound engineer.

The platform delivers control and monitoring of all amplifier functions including AC mains current draw, headroom, protections and faults. The software also includes advanced grouping options.

Armonía is also compatible with both the latest offerings and many of our legacy products. Powersoft amplifiers can connect to a PC running Armonía in two ways: through an RS-485 serial connection or via Ethernet.

Amplifiers of the K and Duecanali Series can be equipped with either or both methods of connectivity while earlier remotely-controllable models have only an RS-485 connection. A system can be configured using both connection pathways simultaneously, extending the functional life of older amplifiers.

With an optional Ethernet KAESOP board, a network can be extended to a virtually unlimited number of amplifiers.

The range of network topologies which can be used in wiring a real system varies between the two communications methods. Ethernet provides a slightly greater degree of freedom, as standard IT network switches may be used to create multiple hub-and-spoke systems.

A looped Ethernet topology is also permissible, which will provide redundancy in the event of a network failure. An amplifier system using an RS-485 network can either be daisy-chained throughout or use the Powersoft PowerHub as a local switch.

Further, a wireless access point can be made directly to any Ethernet-enabled Powersoft amplifier, allowing wireless control via laptop or tablet PC.

Powersoft employs the IEEE 802.11n standard that currently yields faster, more reliable connectivity, extended usable range, plus offers an increase in available channels over earlier versions. This makes 802.11n far more suitable for use in fixed and tour sound applications where multiple amplifiers need to be addressed.

Ethernet networking also assures faster data refreshing and data exchange between each amplifier and the host computer, delivering real time monitoring of amplifier status, remote connection, mains presence, current draw, input signal, output voltage, internal temperature, short-circuit protection, clip and fault.

Armonía also offers real time control of amplifier on/ off/stand-by levels, solo, mute, sensitivity, max output voltage, max mains current draw, presets locking and input selection (digital/analog/KAESOP).

DSP Power
The final area of focus in the development of Armonía was in providing the capability to program and implement extensive DSP functions affecting both input and output signals.

For those amplifiers equipped with optional DSP cards, a greater range of features and facilities were made available including input and output equalization, alignment delays and FIR filters.

We developed the features list through the input of top industry engineers and system designers to address the real needs of delivering and implementing a sound system, keeping in mind that the amplifier itself was taking over the role previously held by external pieces of equipment.

Equalization was implemented to cover all aspects of system equalization.

As such, Armonía makes available up to three EQ layers of 32 filters each in the input EQ, as well as 16 EQ filters plus two crossover filters in the output EQ. In addition, DSP control was further enhanced by Armonía’s grouping feature which combines input EQ, input delay and input attenuation DSP parameters within a graphic interface that is easy to use.

Preset protection was assured through a multilevel locking feature with invisibility of parameters. The input EQ was designed to be used as either parametric or graphic, depending on the intended mission of the EQ.

Armonía’s DSP remote control also has the capability of importing frequency response curves as ASCII data from the most popular measuring software for an easy re-design of loudspeaker presets on location.

Armonía’s display and graphical interface can be customized according to individual needs.

While the output EQ has a similar general appearance of the input EQ, it has several important differences.

The output EQ curve the amplifier employs was intended to be created from a speaker manufacturers’ data for the particular loudspeaker cabinets or arrays used in a system. It provides a range of hi-pass and low-pass crossover filters as well as 16 individual peaking filters.

It is also possible to import and export crossover/filter response curves. The available filters for crossover include Butterworth, Bessel, Linkwitz-Riley, FIR and Hybrid FIR filters with the turnover frequency fully adjustable for all types.

The filter slope was made selectable in 6dB/oct increments from 6 dB/oct to 48 dB/oct for Butterworth and Bessel types, and in 12 dB/oct increments from 12 dB/oct to 48 dB/oct for Linkwitz-Riley types. FIR and Hybrid FIR filters have slopes which are defined by the turnover frequency, so dedicated slope adjustment parameters are unavailable.

Signal delay capabilities allow the engineer to precisely tune the correct time delay for side fill, under balcony or any speakers that are set up beyond the main front of house system.

The delay functions can insert a per-channel fixed delay in the output equalizer as well as in the input equalizer. The primary use of delays added here is to time-align individual drivers in multi-way loudspeaker systems.

Delay values can be specified as time, in 0.01 millisecond (mS) increments up to 32 mS, or as distance in 1 millimeter increments up to 35-plus feet (10.9 meters).

The distance units may be changed to feet by selecting Imperial instead of International. The distance/ time conversion is based on a sound velocity value of 1,125 feet per second (343 meters per second) in dry air at 68 degrees F (20 degrees C).

The design challenges in creating an amplifier capable of becoming a technology platform controlled by intuitive, feature laden software were legion.

The result was the integration of real-world issues experienced with large sound systems, coupled with hard science, to yield a comprehensive software package.

On Tour: The Oak Ridge Boys Are Back

Getting it covered, flown or stacked.

The Oak Ridge Boys are currently taking their unique country and gospel style on the road with the appropriately named The Boys Are Back 150-date North American tour in support of their latest recording release of the same name.

The original group dates all the way back to 1945, founded as the Oak Ridge Quartet, and has seen a lot of changes over its six-plus decades.

But the focus has always been richly textured vocals, with the current lineup consisting of lead singer Duane Allen, tenor Joe Bonsall, bass Richard Sterban and iconic baritone William Lee Golden.

Brantley Sound Associates (BSA) of Nashville is providing the concert systems and support for the tour, which is appearing in theaters and smaller arenas with capacities ranging up to 4,000.

A flexible sound design, particularly for the house, has been implemented by the team of Chris Demonbreun, Marko Hunt and Eric Vogel, who have formulated effective ways to adapt the system to meet the unique needs of the different venues the tour is visiting.

The flexible house system design starts with Adamson Systems Y10 compact line arrays that are either flown or stacked, depending upon the specific coverage requirements and physical configuration of each venue.

A groundstacked Adamson Y10 array, the most frequent method of deployment on the tour.

The compact 3-way Y10, measuring just 10-in (h) by 42-in (w) by 24-in (d) per enclosure, is outfitted with a slide-hinge rigging system providing six 1-degree increments that makes optimum positioning simple whether up in the air or on the deck.

“The rigging design allows us to do whatever is required and get the angles we need,” notes Demonbreun, who serves as system tech as well as monitor engineer.

Through The Ranges
When ground-stacked, coverage is usually achieved with arrays of just six Y10 modules per side, each joined by a single Adamson T21 (dual 21-in Kevlar drivers).

Flown, each array is joined by eight Adamson Spektrix ultra-compact 3-way line array modules and a single Spektrix W cabinet, with a 15-degree trapezoidal cabinet, to provide down fill.

Hunt, who is the long-time front-of-house engineer for the Oak Ridge Boys, determines the PA configuration for each venue, working out array structure as well as optimum angles.

He deploys the Adamson Shooter array modeling and configuration program for additional information when the arrays are flown.

“Almost all of our setups (on this tour) are ground support, so I’ve become adept at ‘guesstimating and eyeballing’ the angles so we can hit balconies and mezzanines while still covering the floor with only six Y10 cabinets per side,” Hunt explains.

“If the balcony is ‘way up there,’ we can tie into the theater system if it allows us to just cover upstairs without hitting the floor and causing phasing problems.”

“Delaying the downstairs doesn’t usually work because there’s no one point of reference. Every seat will hear it differently.”“

“When setting angles we decouple the bottom cabinets at least a degree,” he continues, “and then angle as necessary, trying to have the last two cabs at zero - or close as we can get - to attain the coupling to project to the far reaches.”“

“Sometimes we shade the downstairs a bit at the processors and amplifiers.”

“All of this sits on the mighty T21 subs, which I find to have the most dynamic range of any sub out there and enough power to blow your hat off.”

The sound team – Marko Hunt, Eric Vogel, and Chris Demonbreun – with some of the gear for the tour at the Brantley Sound shop.

“The bass singer is a guy (Golden) who actually can hit fundamental 50 Hz notes, which requires good subs for him as well as for kick and bass. Then we go on up through the ranges with the other singers.”

“I like to have a lot of low mid cone area to give a full sound, and one thing I really love about Adamson systems is the Kevlar cones on the lows and mids. They are so linear sounding, with no harsh overtones.”

Up In The Mix
About 30 minutes are devoted to tuning the system at each stop, accomplished with an assist from an Earthworks measurement microphone and SpectraFoo software.

All loudspeakers are driven by Camco Vortex 6 power amplifiers, with system processing supply by XTA DP200 Series digital signal processors in the racks with the amps.

Hunt utilizes an Avid VENUE Profile digital console for his mix, utilizing all of the plug-ins that come standard with the board plus the McDSP Classic Pack.

“Since the ‘Oaks’ are a vocal group, I strive to keep their voices on top of the mix,” he notes.

“But they have always liked it to rock, so the band is up in the mix and there are also a lot of instrumental solos, so I occasionally get a complaint that the band is too loud.

There are a lot of older folks at our shows that, I’m sure, would be happy if the whole show was a cappella.”

On stage, the Oak Ridge Boys are outfitted with Sennheiser G2 wireless in-ear monitoring systems, with a pair of EAW MicroWedges also supplied for one of the vocalists.

Microphones are predominantly Audio-Technica, joined by select models from Shure and Sennheiser. Demonbreun, who has served as the group’s monitor engineer since 2009, provides mixes with an Avid VENUE D-Show with companion Mix Rack.

“An awesome thing about the Avid console is that I’m using an iPad as a remote control for the desk,” he explains.

“It’s really great because I can be on stage during rehearsals and sound check, and it also allows me to stand where everyone on stage can see me if ‘monitor world’ has to be in a crazy location.”

“The band and singers love it because I can be there next to them instead of trying to yell across the stage to tell me what they want.”

The Boys Are Back tour will continue to crisscross the continent, with published dates running all the way through November.

The system will remain consistent throughout, with Hunt concluding, “We had been totally at the mercy of ‘system du jour’ for years when Brantley Sound acquired a set of Y10s and we took them out.”

“They’ve been a staple for us ever since.”

Identifying The Seven Characteristics Of An Amateur Mix

Although some artists and mixers get lucky by flying through a mix, making and mixing records usually takes a lot of time and attention.
This article is provided by Bobby Owsinski.

This may come as no great surprise to you, but I’m frequently asked to review mixes.

While many are remarkable and are a display of great talent, there does exist a category of mixes that, for want of a better term, you could call “amateur”.

An amateur mix usually means that you’ve not spent enough time listening and learning, but when you can’t determine why a mix sounds great, the next best thing is to determine when you have something that’s, shall we say, less than great.

So, excerpted from The Mixing Engineer’s Handbook, here are seven characteristics of an amateur mix.

Do your mixes exhibit any of these characteristics?

1) No Contrast
The same musical textures are used throughout the entire song. This is generally an arrangement issue, which the mixer can affect somewhat since mixing is so much more than balancing.

It’s influencing the arrangement by what you mute, emphasize or lower in the mix.

2) A Frequent Lack Of A Focal Point
There are holes between lyrics where nothing is brought forward in the mix to hold the listener’s attention.

Granted, this is an arrangement issue too, but it’s your job as a mixer to find some point of interest and emphasize it.

3) Mixes That Are Noisy
Clicks, hums, extraneous noises, count-offs, and sometimes lip-smacks and breaths are all things that the listener finds distracting.

It may be a pain to eliminate these distractions but you’ve got to do it to take the mix to where it has to be.

4) Mixes That Lack Clarity And Punch
Instruments aren’t distinct, and low-end frequencies are either too weak or too big.

This is really the number one indication of an amateur mix, especially in the low end.

It’s either way too heavy or way too light. The way around this is to listen to other records that you think sound great and try to emulate the sound. Sure it takes time, but it will get you in the ballpark.

5) Mixes That Sound Distant And Are Devoid Of Any Feeling Of Intimacy
The mix sounds distant because too much reverb or overuse of other effects.

This is another common trait since a newbie mixer thinks the plug-in effects are so cool (because they are!) that they want to use them all on everything all the way through the song.

You’d be surprised just how many effects are used in a great mix sometimes, but the results are so subtle that you can’t really tell unless you had the original non-effected sound to compare with.

In an amateur mix, you hear them all screaming at you all the time. If you can make it sound great without effects first, you’ll automatically moderate their use.

6) Inconsistent Levels
Instrument levels that vary from balanced to too soft or too loud or lyrics that can’t be distinguished.

Once again, a newbie mixer usually sets the faders and forgets them, but mixing is just as dynamic as the music. Every note of every solo and every word of the vocal must be heard.

Even with automation as sophisticated as it is these days, it still takes some time and a critical ear to be sure that everything is heard.

7) Dull And Uninteresting Sounds
Generic, dated or frequently-heard sounds are used. There’s a difference between using something because it’s hip and new and using it because everyone else is using it.

The latest example is the Auto-tune keying trick initially used by Cher, then copied by the Backstreet Boys and most recently Kanye West and others. They’ve already used it, so give it a rest.

It doesn’t mean you’re cool if you use it, just a copycat. The same with generic synth patches from a Roland Motif (this problem goes all the way back to the 80’s with the electric piano sound of the DX-7).

We’ve heard them all. Time for something new. Most great artists strive for something that no one has ever heard before.

Although some artists and mixers get lucky by flying through a mix, making and mixing records usually takes a lot of time and attention.

We’d all like it to go faster, but there are some things that you just can’t let get by. Eliminate the seven characteristics of an amateur mix and you’ll be surprised just how good your song can sound.

RTS Intercom Systems Launch The ADAM-M Intercom Matrix Frame At NAB 2011

The ADAM-M includes support for MADI, AES, RVON, and Analog connectivity.

RTS Intercom Systems is pleased to introduce the all-new ADAM-M compact digital audio matrix frame at NAB 2011.

Extending the ADAM platform, this new, more compact 3RU matrix frame supports eight interface cards in addition to redundant master controllers.

In keeping with the RTS principle of Backwards Compatible, Forward Thinking, the ADAM-M is fully compatible with all existing ADAM cards, including the new MADI-16 Plus (also being introduced at NAB 2011).

When combined with the MADI-16 Plus, the ADAM-M can be configured with up to 224 ports – the most in its class. In addition to MADI, users now have the option of configuring a very compact frame with AES, RVON, and analog with full redundancy.

These advanced connectivity options save additional space and complexity by reducing the need for external cross-connect panels, greatly simplifying wiring. In environments such as mobile production trucks where space and setup time are at a premium, the ADAM-M provides an optimal intercom solution.

True to the term “Forward Thinking,” the ADAM-M is designed to fully support the next generation of intercom technologies. The backplane architecture supports higher performance I/O, and is fully capable of supporting 1,000+ time slots for integration into full ADAM-based systems.

In addition to compatibility, the ADAM-M also boasts striking new aesthetics. Its contoured front panel and compact form factor raise the bar for industrial design across the entire spectrum of intercom matrices.

It also takes design cues from the RTS CLD series color display keypanels, further enhancing the unified family look of RTS intercom components. The ADAM-M chassis is more than just a pretty face, however. The front panel is designed to provide system status at-a-glance, including card activity, power status, and cooling function.

RTS’ long history in broadcast and critical communications has resulted in an inherent understanding of what “fail-safe operation”¬ really means.

Since many users rely on RTS matrices in critical, always-on installations, all removable components of the ADAM-M have been made to be hot swappable. With the ADAM-M, installing a new master controller, replacing or maintaining cooling components, or even a power supply can be accomplished seamlessly with no interruption to the system.
