Atlas Sound Debuts DSP2210 & DSP2212 Digital Processor And Amplifier

Atlas Sound DSP2210 and DSP2212 digital sound masking/paging systems are self contained, digital signal processors with integral amplification designed to efficiently route and mix masking, paging, and background music sources. Applications include speech privacy and general paging for office spaces, health care campuses and secure government facilities. 

Masking source is completely random and non-repeating (up to 215) hours with EQ adjustments programmable per output zone. Both models include dual channel Class-D amplification rated at 25W/channel (@ 70.7V) and a built in telephony interface simplifies paging set-up.

The system is expandable up to (32) systems (64 zones) with primary and secondary assignment in a zone page dialing plan (2-digit DTMF) with “All Zone” and “Group zone” pages simply configured via the GUI. A powerful, fixed architecture DSP provides equalization, dynamic and routing priority control for all input sources as well as line level and amplified outputs.

Model 2212 includes AVB (Audio-Video Bridging) network interface allowing paging and BGM sources to be shared between multiple DSP8807’s or DSP2212’s.

“The DSP2210 and DSP2212 are the other two new products in the sound masking category that we are releasing this year”, said Steve Young VP of Sales & Marketing.

He continued, “the DSP2210 and DSP2212 are feature rich sound masking processors that can be used in small to medium applications. By themselves they are extremely useful but when the DSP2212 is used on the same network as the DSP8807 our integrators can truly handle any size sound masking application.”

Carl Tatz Design Chooses Argosy Dual 15 For New Village East Studio

Village East, the personal mix room of renowned multi-platinum/Grammy-winning engineer/producer Bob Bullock, recently came online showcasing the world-class performance of the Carl Tatz Design PhantomFocus System monitor tuning protocol, as well as a number of performance and design elements hand-picked by Tatz, including the Argosy Dual 15 DR 800 studio workstation.

Bullock, who has engineered and mixed for artists such as Reba McEntire, George Strait, Travis Tritt, and Shania Twain, realized that with the caliber of his client work, he needed a personal studio environment which could sonically and aesthetically rival any high-end studio, and called on personal studio guru Carl Tatz to design it.

Tatz chose the Argosy Dual 15 DR 800 studio workstation to be the centerpiece as Bullock’s control surface and to compliment his acclaimed PhantomFocus System tuning. 

“My workstation of choice for engineers working in the box, which may be a majority nowadays, is the Argosy Dual 15 with the 800 rack modules, “ says Tatz. “It has a minimum monitor reflection architecture and handsome silhouette making it the perfect complement to the PhantomFocus System.” 

Along with the new Carl Tatz Signature Series by Auralex turnkey acoustical treatment system that emulates the design and performance of Tatz’s custom-designed control rooms, he also employed Dynaudio Professional M1 reference monitors driven by a Bryston, 4B SST2 power amplifier.

“When I design a studio, I choose partners who understand my vision and the standard for design and performance of the PhantomFocus system,” says Tatz. “I use elements which are both aesthetically pleasing and high performing.

The Argosy Dual 15 DR 800 has the slanted back and I love the way it looks – it takes the control room to a serious level in terms of design. And it provides the perfect positioning environment for the sweet spot.”

The Argosy Dual 15 DR-800 has a sleek, symmetrical design, featuring a front desk area and two 15-dgree angles for a wrap-around feel. The Dual 15 features two DR 800 rack modules, with a slanted top to defeat early reflections. The Dual 15 is designed to enhance the studio workspace by bringing essential order to all the equipment, putting all the controls within easy reach of the busy engineer. A padded armrest offers comfort for long studio sessions.

According to Tatz, all the manufacturers that he worked with on the project can share in the stunning results at Village East. Now music professionals can have a truly state-of-the-art mix room second to none at an affordable price point.

“The PhantomFocus System and all of its manufacturer partner elements made it possible to implement a world-class studio in a bedroom,” adds Tatz. “Bullock’s Village East is a tremendous showcase of what is possible nowadays. The room design is gorgeous, the monitoring is superior, and Bob and his clients can feel confident here knowing that it has the acoustics, monitoring, and vibe of a peerless mix room.”

Allen Products Debuts Updated Ceiling & Wall Mounts At InfoComm 2012

Allen Products rolled out several updated ceiling and wall mounts at InfoComm 2012, including the Steerables Wall Mount, Adjustable SocketMount, Adjustable U-Bracket and several MultiMount solutions.

Steerables Wall Mounts suspend and aim loudspeakers, equipped with suspension or mounting points, from walls and other vertical structures. Users can make or remake pan-and-tilt adjustments within seconds, offering unprecedented ease and precision.

Designed for use with permanently installed loudspeakers in churches, schools, gymnasiums, auditoriums, theme parks, nightclubs, and bars and restaurants, Steerables Wall Mounts feature a unique cross-arm steering mechanism providing up to 360 degrees of pan control. Their structural steel alloy assembly is coated with a baked-on black textured powder coat finish.

Steerables Wall Mounts can support loads of up to 100 pounds./45.5 kg. with a 5:1 safety factor. In addition, tilting can be achieved with Allen Products’ U-Series bracket or the Steerables Tilt Cable Kit.

Allen Products Adjustable SocketMount supports and aims loudspeakers that are equipped with pole sockets to walls and other vertical structures. Both pan and tilt rotations are provided for optimum aiming, and the support arm folds down when not in use.

The Adjustable SocketMount is designed as a temporary solution, as its easy-on, easy-off feature allows loudspeakers to be relocated to other SocketMounts and/or tripod stands, thus reducing the need for additional loudspeakers and saving floor space.

Adjustable U-Brackets mount loudspeakers quickly and reliably to walls and poles, and from under ceilings, balconies, overhangs and other structural mounting surfaces. These brackets give installers multiple options for mounting speakers to irregular or unpredictable mounting surfaces due to their unique mounting pattern.

Allen Products Steerables Wall Mount. (click to enlarge)

Adjustable U-Brackets support most of the mountable loudspeakers in the 60 lbs./22 kg. range, or less, and their open side-arm slots allow a single installer to easily mount loudspeakers in this weight range. Loudspeakers rotate within the arms of the U-Bracket kit to aim sound toward the audience. It then locks into position, with the included friction washers and compression hardware.

Allen Products also introduced several updated models of MultiMounts at this year’s show, including its MultiMount MM-120, MultiMount MM-024 and MultiMount MM-020-CM.

• The MultiMount MM-120 pan-and-tilt speaker mount is a sturdy and adjustable speaker mount that is safe and exceptionally easy to use for installing large-format loudspeakers. It accommodates up to 120 lbs. with greater than a 5:1 design factor. The speaker brackets’ mounting holes match two standard speaker mounting hole patterns, the 6.88- x 3.44-inch and the 2.75- x 5-inch, and two VESA mounting hole patterns, the 75- x 75-mm and the 100- x 100-mm.

The bracket’s pivot housing provides 65 degrees of tilt adjustment and the screw-drive thumb-wheel adjustment makes tilting speakers very stable. The pivot housing also provides a full 180 degrees of pan rotation. A clutch-style lock holds it in position. The wall bracket accommodates stud mounting with two centrally located mounting/alignment holes and a slot that allows for plumb adjustment. Four outer holes allow it to be secured to other structural surfaces.

• The MultiMount MM-024 supports loudspeakers weighing up to 60 lbs./27 kg, enabling the quick attachment of them to walls, ceilings, overhangs and other structural surfaces. Speakers can be aimed and locked in almost any direction or angle through the use of independent pan, tilt and clockwise adjustments. MultiMount-024 supports vertically oriented standard speaker mounting-hole patterns.

Tilt adjustments are made independently at the side of the speaker adapter plate. Panning adjustments are also made independently at the mounting plate and a third rotation is available between the speaker and the support arm. This rotation is especially useful in directing sound from the ceiling and under balcony applications, where mounting space is limited.

• MultiMount MM-020-CM is specially designed to suspend loudspeakers (weighing up to 60 lb./27 kg.) from overhead structures using a customer-supplied schedule 40, one-half inch NPT pipe. This allows the installer to bring the loudspeaker down from any height, positioning the speaker closer to the audience, further reducing the speaker’s size and power-rating needs. The MM-020-CM provides a very clean loudspeaker installation because signal wire and safety cables can be passed through the pipe from the ceiling to the speaker’s terminal block without being seen.

Also, this design adapts directly to standard loudspeaker mounting-hole patterns so no modifications are necessary. The oval-shaped ceiling attachment plate offers a sufficient mounting surface with four one-quarter inch mounting holes to secure to overhead structures including beams, beam clamps, etc. Pan-angle adjustments are achieved where the MultiMount and the vertical tube (pipe) connect, with down-tilt adjustments at the mount’s two-side clutch-lock points.

“We are thrilled to present an expanded line of ceiling and wall mounts at this year’s show,” says Paul Allen, president, Adaptive Technologies Group. “Allen Products provide a wide range of standard and custom mounting solutions to cater to nearly every possible configuration request. We will continue to develop new products based on our customers’ feedback.”

Adaptive Technologies Group combines the efforts of Allen Products, ATM Fly-ware and Adaptive Video Walls and Displays, and offers rigging and mounting solutions for a wide range of audio and video applications. Each brand offers its own standard and unique time-saving solutions, plus unlimited custom products for any venue or application. Based in Signal Hill, California, all overhead products and parts are made and assembled in the USA.

Consultants, Contactors, Retailers - And Your Church Sound Project

Many churches don't see the wisdom of paying for professional help with sound system needs, too often to their own detriment

When faced with a need for either a significant improvement to an existing sound system or an entirely new sound system, the most often-heard advise is “hire a qualified consultant.” Or at least it should be.

But many churches balk at the notion of paying a fee to a professional to help with sound system needs.

The thinking: this is not money well spent because there always seems to be “someone” in the congregation confident in his own abilities to choose appropriate equipment and put it all together. Or, the local music store will provide the required expertise - why pay anyone else?

These approaches have lousy track records, wasting buckets of money and making everyone involved with the church suffer through poor sound quality for years. And years…

Full disclosure at this point: I am a long-time electro-acoustic consultant, so there might be temptation to think I’m biased in dispensing advice.

But the reality is that I truly wish I didn’t have to address this topic, because I’ve spent my career trying to help churches pick up the pieces after they’ve suffered mightily by putting their trust in totally unqualified personnel.

The bottom line is that a qualified consultant who specializes in live sound reinforcement (because this is what a church sound system is designed to do) will end up saving the church money, time and a whole lot of heartache.

Sound systems may be obtained in three basic ways:

1) All at once or piece-meal from a retail outlet (music store) or catalog vendor, usually installed by church members.

2) All at once or piece-meal from an AV contracting (“design-build”) firm that usually does at least part of the installation as well.

3) All at once with design by a qualified consultant and installation by a contracting firm that both work as colleagues in the process.

New let’s clarify these sources and what they do.

Retail Outlets
A retail supplier or catalog house that sells professional audio equipment does not design or engineer sound systems, and in most cases they’re not qualified to do either. All but a few of the largest do not employ seasoned live sound system experts. Very few, in fact, have staff with significant experience in live sound system design or operation.

Staff members are primarily part-time musicians or home studio owners who are there primarily to supplement their incomes. And musicians and home studio people are rarely qualified to provide sound reinforcement design advice, nor do they usually have a grasp of architectural accommodation, nor do they possess the necessary skills in installation and related safety issues, nor electrical systems and related issues, nor the physics of electroacoustics.

Further, they’re not familiar with the National Electrical Code (NEC) that must be adhered to, both for inspections and insurance purposes.

Usually, they can’t properly employ room and system modeling (computer-assisted prediction), and they’re not trained or invested in test and measurement skills/equipment that help truly optimize a sound system.

They’re usually not members of any pro audio and/or acoustics trade organization, and they’re also prone to dismiss many significant issues as “not that complicated.” (And if you hear someone say this, run away screaming immediately!)

Note that I am saying most - not all - fit these criteria. Anyone still bold enough to tread down this path should at least understand the right questions to ask.

Contractors
A contracting firm usually specializes at installing systems, and many also offer system design services. However, be aware that this does not necessarily mean that they’re qualified to design systems.

Some have invested time and money in modeling and optimization training and equipment, and also have the necessary experience in using these tools and others to do successful design work.

But others, even with training, may be lacking the necessary design skills, whether it’s due to lack of experience and/or other factors. (Do you really want someone learning how to design when it’s your system?)

In other words, just because someone shows you a technical document on a computer screen - and goodness, it does look complicated - does not mean the document is providing any salient information that will translate into a better sound system design. Or, that the person doing the showing knows much more than you.

This is a common sales tool that is used to show off and “wow” the customer, when in reality, there might be little depth of knowledge and understanding behind the “dog and pony show.”

Further, contracting firms are increasingly focused on selling total audio-visual (AV) system packages, encompassing not just sound but also lighting and video. As a result, the emphasis is not just on sound, with staff members sometimes not likely to possess deep knowledge on the subject.

Like retail outlets, no single contracting firm can carry all lines of audio equipment, and they’re also bound by agreements with manufacturers to sell certain amounts of each brand they carry.

They’re also not prone to attend your project meetings without additional fees, and other than a complimentary site visit, they’re also not likely to budget time for programming and design development. They usually don’t make provisions for the focused, useful training of volunteer sound operators on aspects such as the “how and why” of live sound, as well as mixing, politics and so on.

Better contracting firms will have licensed engineers on staff, and they make it a practice to send staff members to seminars, workshops and other continuing educational endeavors. Further, these firms belong to respected trade organizations such as the National Systems Contractor Association (NSCA) and the Audio Engineering Society (AES).

There is one caveat to be pointed out. Some contracting firms offer true system design-build services, and they employ qualified designers, either on staff or via a business arrangement. This approach and structure has proven successful in some situations.

The bottom line is to understand what a contactor can and cannot do - again, if you simply ask the right questions.

Consultants
A qualified electroacoustic consultant will offer ample experience working with and designing sound systems for churches, and often, other performance spaces. They will have attended advanced live sound related seminars and workshops, and they continue to do so because this is their specialty.

Consultants may or may not have licensed engineers on staff, but will have a firm grasp on safety issues, and are familiar with the terminology and methods employed by architects, other consultants (theater, acoustics), specialty engineers (electrical, structural, mechanical), and contractors (carpenters, electrical, HVAC, etc.).

Qualified consultants will also have worked at various times for a church or performance venue as staff sound system operators. Often they will have a background in contracting, and should have some background in music as well.

They will have membership with organizations such as NSCA and AES, as well as the ASA and USITT, and it is not uncommon for some staff to be trained as professional engineers (this is designated by a “PE” in their titles on business cards.)

They attend several trade shows each year because it provides insight into emerging technologies and new equipment, and it also allows them to attend technical papers and to sit in on technical committees. Participating in these conferences keeps the consultant “connected” and helps to prevent them from becoming either too proprietary or experimental.

To The Chase
One of the most significant issues: the consultant is employed directly by the client to provide the best possible system design at a reasonable cost. (It’s under the category of “who’s looking out for number one?”)

As a result, consultants specify equipment based upon its merits and value. Their affiliation with manufacturers is one of mutual respect and not unduly influenced by numbers. This independence is paramount.

However, many consultants are asked by manufacturers to participate in product development, or to provide valuable feedback so that minor design flaws may be corrected. (The better contractors and design build firms do this as well.) All must walk the lie between incorporating new products/technologies and undertaking unnecessary risk for every system project.

Consultants must also participate in your project meetings, and at the end of the design phase, they deliver a completely engineered audio system design in the form of a bid package, plus a list of pre-qualified contractors to bid on the project.

The specification should allow very few items that the bidding contractors are allowed to substitute. Specifying exact equipment for all but the most mundane components of a system is what the consultant is paid to provide, and the consultant should be able to clearly detail to the client why each device is required.

One other aspect of a complete system design is provision for future needs. This may take the form of recommending more mixer input channels than are initially needed, additional wire, cable and conduit (installed at the outset even if they’re not needed until later), and a digital processor that can easily be expanded in functions and input/output capabilities. This can save thousands and thousands of dollars down the line.

Finally, the design package should be complete and not require the contactor to “fill in the blanks.”

Getting Options

Another valuable ingredient is the bidding part of the process itself. If a church attempts to shop around for a sound system package, not only is this very likely to lead to multiples of package proposals (these are not designed systems in any way, shape or form), but prices will vary widely.

All of this leads to chaos since there is no way to qualitatively compare the multiple proposals.

Aside from confusion about what the church is really buying, this also opens the door to temptation to accept a lower quality system based solely on dollar value.

A consultant designs the appropriate system and estimates what it will cost. If this is too much money, then the consultant may be able to provide a lower cost option, and with a full explanation of the ramifications.

Note, however, that consultants must be willing to say “no” when being pressured to provide a compromised design, and if necessary, they will walk away from a client with unrealistic expectations.

Another option is to stage the system purchase and installation into several phases, allowing the client to obtain the best system over time. But note that this is still a “system” design and not a piece-meal approach.

As part of the bid package, the consultant provides a list of several pre-qualified contractors and they bid on the same system design. This results in no ambiguities, and the client can then accept the lowest (or one of the lowest) bids.

Programming is the most important first step in developing a design that provides what is needed. The consultant must also attend worship services and interview key personnel to establish what their needs and hopes are. This also helps the consultant to identify the technical capabilities of the crew.

Following programming and the various design phases (schematic design, design development), the entire sound system design must be presented in the form of contract documents, which include drawings and a written specification.

The drawing set must include the functional aspects of each part of the system, as well as detailed drawings of key components such as loudspeakers (clusters, arrays, rigging and mounting methods), rack elevations, custom panels, and the isolated ground AC (electrical) power system.

The latter is provided as a concept (because consultants are not licensed to engineer them), and then it must be approved, detailed and stamped by a licensed electrical engineer in the local where the church is being built or the system is being installed. This is also the case for any suspended devices such as loudspeakers.

Once the contracting firm is selected, the consultant serves as the primary interface on all issues related to the system, and then interfaces with the client on any aspects of note.

Yet another important part of the services provided by a consultant is an ability to measure and optimize the system after it is installed, and then to train the users in its operation. This completes the picture.

Finally, the consultant will be available to answer questions later, as they crop up, which can inevitably happen with a new sound system.

Churches that invest the time and care in finding and vetting qualified candidates for design and install services are much more likely to achieve a sound system that serves their needs, and will do so for many years to come, while also receiving a very high return on their investment.

Straightforward Approach To Setting An Optimized Audio System Gain Structure

Over the years I’ve seen many haphazard approaches in establishing gain structure through a sound reinforcement system.

Often rough adjustments can be made to make the problem less apparent, because gain is easily and cheaply available in today’s industry.

Years ago, when a 100-watt power amplifier was used to power the main loudspeaker system, gain structure was a critical issue. Today, with the advent of amplifiers that can output levels of 1,000 watts or more per channel, proper gain structure can be easily overlooked as a critical element in the performance of a system.

Powerful amplifiers, however, are not an excuse for an individual to lack a firm understanding of proper gain structure. Many of today’s signal processors and amplifiers have jumpers, switches, or knobs that, if adjusted properly, will maximize the systems signal to noise ratio while also ensuring the system will safely operate at the levels that are required.

First we’ll determine how much gain is required throughout the system, from the console to the listener. Then, once overall gain requirements are known, we can discuss the approach to setting the system’s gain structure.

How much gain is enough?

A good designer will always have an established sound pressure level (SPL) criteria for each system in which he/she is working on. Without this pre-determined resultant SPL, you may often find yourself over or under specifying the total gain required in a system.

So, let’s establish a criteria for the purpose of discussion. We will assume that we are designing a sound system for a church that has a contemporary music program. During the music portion of the program, it is anticipated that peak levels in the room need to reach nominal levels of 95 dB SPL, with peaks of 101 dB. It is also the intent to provide 10 dB of headroom. Our design criteria is now determined, and we can begin our discussion of gain structure.

The first thing to determine in the system is the amount of loss due to distance. For the purpose of our example, let’s assume that the furthest distance a listener will be from the speaker is 80 feet. Because sound radiates spherically, the attenuation is proportional to the square of the distance from the source, and thus there is a 6 dB reduction for each doubling of distance.

Assuming that the sensitivity of the loudspeaker is given in reference to 1 meter, this can be represented mathematically by the equation:

(Equation 1) SPLdist-loss = 20 log (distance in feet / 3.3)

The 3.3 factor is used to convert feet to meters. Using this equation, we determine there will be a total loss of 28 dB as a result of distance. We can now calculate the maximum output level of the loudspeaker that we will require in order to achieve our design criteria.

We have already determined that we need a maximum SPL level of 111dB at the listener position (101 dB peaks with 10 dB of headroom). At the loudspeaker we will need a maximum SPL level of 139 dB (111 dB at the listener position + 28 dB of loss due to distance.)

The selection of the loudspeaker is the next step in the process. Any loudspeaker that is specified will have a sensitivity and a maximum power rating. The sensitivity is normally given in dB SPL at 1 meter when a 1-watt signal is applied to the input of the loudspeaker, and is usually given in AES watts.

This AES measurement is a clearly defined standard in which a band of pink noise from 125Hz to 8Khz, with +6 dB peaks, is applied to the input of the loudspeaker for a period of two hours. Any loudspeaker that has its power rating in AES watts can very easily handle short-term peaks of +6 dB above the AES rating.

The maximum output level at 1 meter away from a loudspeaker will be derived from the formula:

(Equation 2) SPLmax-AES = sensitivity + 10 log (AES power rating)

(Equation 3) SPLmax = sensitivity + 10 log (AES power rating) + 6

Any loudspeaker we select must have an SPLmax of at least 139 dB. We will take one particular manufacturer’s loudspeaker that has a sensitivity of 112 dB at 1 watt/1 meter. The high frequency component can handle 200 watts, AES. Using the equation above, we find that the SPLmax equals 141 dB. This loudspeaker will have the ability of achieving our design criteria.

To complete the design, we must choose the correct amplifier size for the application. Amplifier power ratings are given in watts, but unlike loudspeaker AES power ratings, amplifier power ratings are the upper limits and do not include any crest factors.

For the purpose of discussion, let’s assume that we have a 3-way loudspeaker system (loudspeakers with high, mid and low sub-sections), with the following AES power ratings and sensitivity ratings:

Loudspeaker Sensitivity & Power Ratings

Loudspeaker—————————Highs———————Mids————————-Lows
Sensitivity———————————112————————-109————————101
AES power rating————————200————————-400———————-1000
Peak SPL———————————141————————-141————————137
(Using Equation 3)

The high and mid sub-sections of a single loudspeaker can handle the minimum SPL requirements of 139 dB at 1 meter. However, the low frequency sub-section will require two loudspeakers.

And then, by doubling the number of loudspeakers, we will obtain a +6 dB gain, which results in a low frequency peak SPL of 143 dB. We can now go directly to our amplifier selection. In order to calculate the amount of power required, we need to use the following equation:

(Equation 4a) PWR(dB) = SPL Criteria peak - sensitivity + SPLdist-loss

(Equation 4b) PWR (watts) = 10 PWR(dB)/10

The peak SPL criteria was established earlier at 111 dB SPL (96 dB nominal + 6 dB peaks + 10 dB headroom). The loss due to distance is 28 dB. By plugging these numbers into equations 4a and 4b (above), we obtain the following results:

Amplifier Power Requirements

Loudspeaker—————————Highs——————-Mids————————Lows*
Calculated Minimum Power———27 dB——————30 dB———————-32 dB
Power in watts**——————-500 watts—————1000 watts—————1585 watts

* One loudspeaker will be required to provide an SPL criteria peak of 105dB SPL since two loudspeakers will give us our required SPL criteria peak of 111 dB SPL.
** This is peak power, not AES. The AES power handling would -6 dB lower than this (divide by 4).

Now that the amplifier size has been determined, the next thing to look at is processing level inputs and outputs.

Most sound consoles can comfortably handle an output level between +18 dBu and +24 dBu.

This, in turn, will feed the processing equipment. Analog processors can usually handle +18 dBu input and output signals. This is the first place in line where attenuation or a pad may be required.

If you are using a console that can output +24 dBu, you will want 6 dB of attenuation at the input of the audio processor. This can usually be achieved by the input attenuators on the signal processor.

The outputs of the signal processors require a bit more discussion. Many DSP devices have either output switch settings or output jumper settings that can select between 0, +6 dB, or +12 dB, so the obvious questions are “Why are there different options?” and “When do you use them?”

To answer this, we must first continue our discussion about amplifiers.

AMPLIFIER INPUT LEVELS
Many manufacturers have input selection settings than can choose between 0.775V, 1.4V, X20 (or 26 dB), or X40 (or 32 dB). For the purpose of discussion, the table below indicates the input level that 200-, 400-, and 800-watt amplifiers will accept before the amp clips.

The 0.775V and the 1.4V input level settings indicate that all amplifiers will clip at the same input level. For the X20 (26dB) or the X40 (32dB) selection settings, the size of the amplifier and the load on the amplifier will determine the level at which the amp will clip. It is very important to be able to understand the clip levels and gains of the amplifiers in both dB and in voltage.

For 0.775V or 1.4V input sensitivity

(Equation 5a) Gain (volts) = sqrt [Max power rating * load (ohms)] / input sensitivity
(Equation 5b) (dB) = 20 log[Gain (voltage)]
(Equation 5c) Clip Level (volts) = input sensitivity (0.775V or 1.4V)
(Equation 5d) Clip Level (dB) = 20 log [clip level (volts)]

For X20 (26 dB) or X40 (32 dB) gain

(Equation 6a) Clip level (volts) = sqrt [Max power rating * load (ohms)] / gain (20 or 40)
(Equation 6b) Clip level (dB) = 20 log[Clip level (volts) / 0.775V]
(Equation 6c) Gain (volts) = gain (20 or 40)
(Equation 6d) Gain (dB) = 20 log[gain(volts)]

Amplifier Input Clip Levels
 
———————-200 Watts————————400 Watts————————800 Watts
X20 (26 dB)———-8.2 dB———————————11.2 dB—————————-14.2 dB
X40 (32 dB)———-2.2 dB———————————5.2 dB——————————-8.2 dB
0.75V——————0 dB————————————-0 dB——————————-0 dB
1.4V——————-+5 dB———————————-+5 dB——————————+5 dB

Now that we have thrown all of these numbers out there for you to ponder over, we now need to know when we would want to use these different input settings.

The primary factor in determining which settings to use is determined by the designer’s requirement for the system’s noise floor.

If noise floor is not absolutely critical (NC-25 or higher spaces), then the amplifiers can safely be set on 0.775 (or preferably 1.4V if available).

Because the actual gain of the amplifiers is quite high (~X40 for a 100 watt amp to ~X130 for a 2500 watt amp), the noise floor will be higher. The clear advantage, however, is that you do not need to calculate the attenuation needed for every channel of every amplifier.

If noise levels are a critical concern, then constant gain settings should be used, but you will need to calculate the attenuation for each amp channel.

To conclude our discussion on signal processing and the output level switches on DSP devices, if you are using an amplifier that has its input sensitivity set on 0.775V, then the output of the DSP should be set at 0 dB. This will provide 18 dB of attenuation between the console and the amplifiers.

If the input sensitivity of the amps are set at 1.4V, then the output of the DSP should be set at 6 dB. If you are using constant gain, then each output needs to be addressed on an individual basis.

One final note on gain structure worth mentioning is to always have a good sense for what is occurring with the system equalization. Let’s assume that there is a large +10 dB boost in the EQ at 8K.

During system tuning it may make the speakers sound very well and provide extended high end frequency response, but 8K signals will clip the amplifiers 10 dB sooner than the rest of the system.

Similar problems may arise from very large EQ cuts, but if at all possible, for gain structure purposes, it is better to cut than to boost, and it will always be best to keep your cuts and boosts to an absolute minimum.

Aphex Introduces New Audio Xciter App

Aphex (Booth C11142) is proud to announce the Audio Xciter App, the first audio app that dynamically enhances and improves the quality of digital music (and audio books, podcasts etc.) on smartphones and other personal computing devices.

It has been a goal of Aphex Chairman/CEO David Wiener to help musicians and music lovers make the most of every music experience. Audio Xciter is a testament of Wiener’s drive to end the debate about poor audio quality in digital devices.

Designed for phones and tablets that use Apple iOS and Android operating systems, Audio Xciter uses patented Aphex technology to improve the quality of digital music by analyzing and enhancing the audio signal in real time by applying the same kind of processing power developed by Aphex.

“Heavily compressed digital music file formats – MP3, for example – have taken a lot of sonic performance out of music recordings,” stated David Wiener, “So Aphex has taken its professional studio technology and created this app in order to restore the detail, richness and spaciousness to your audio experience.

“The result is a more immersive sound that more accurately reflects the original intentions of the artists, producers and engineers.”

The Audio Xciter App analyzes a music file while it’s playing and in real time restores missing harmonics lost through data compression and production inefficiencies.

The sonic benefits of the Aphex Audio Xciter App apply to any kind of playback monitoring system or device, from headphones and earbuds to home and auto speaker systems and device docks – all will deliver dramatically improved audio quality via Aphex’s Audio Xciter app.

Aphex will be giving free copies of the app to industry attendees and media who stop by the Aphex booth at InfoComm. Just come by and ask for a free copy of the app, and Aphex will arrange for a gift app to be emailed directly to you.

In the recording studio, leading artists once paid as much as $30 per minute to license the Aphex Exciter audio enhancement system for mixing and mastering.

Now, music lovers will be able to try out a fully functional demo version of Audio Xciter as a FREE download that gives them a 15-minute per day test drive. Once users have tried the App and choose to purchase and download, there are two options: basic and Studio versions.

The Audio Xciter basic version ($4.99) allows a fully automated version of the Aphex technology to be engaged on their device, giving three options for settings. With Audio Xciter Studio ($4.99 in-app upgrade), users will have access to the exact same array of parameter controls found on Aphex’s legendary pro audio Exciter rack products, allowing them to adjust the App’s settings to customize the enhancement details and sound to their own tastes.

Both versions of the Audio Xciter App will be available through the Apple iTunes App Store for iOS users, and the Android Store and Amazon.com for Android.

Audio Xciter automatically plays all your existing music and playlists. It does not copy your audio files – preserving your valuable memory – and the processing is done in real time. The Aphex process uses a patented method of dynamically enhancing the harmonics and low frequencies present in audio that get truncated by bit-rate reduced formats such as MP3.

Audio Xciter represents the first time that the Aphex technology has been brought from the recording or broadcast environment and made available for personal mobile devices.

The Aphex Audio Xciter App’s ability to let you hear instruments and vocal details you never realized were there is summed up succinctly by GRAMMY Award-winning record producer and engineer Alan Parsons, known for his work on classic Beatles and Pink Floyd recordings, among others: “The Audio Xciter will transform your listening!”

The Aphex Audio Xciter will indeed transform your listening experience by revealing nuances in music files that have been obscured by the digital process. The Aphex Audio Xciter brings you closer to the music you know and will help you discover new music and artists by making the experience of listening to digital music files much more rewarding.

PreSonus Adds Powerful New Free Features To StudioLive Mixers

Integrated Smaart frequency analysis, new equalization and talkback features, and even more extensive iPad control are included in PreSonus’ free Universal Control 1.6 and StudioLive Remote 1.3 for iPad updates.

“All current owners of our StudioLive 24.4.2, 16.4.2 and 16.02 can immediately use these enhancements,” noted PreSonus Executive Vice President of Product Development John Bastianelli. “It’s further proof of our commitment to providing complete problem-solving systems, not just hunks of hardware.”

With Universal Control 1.6, Rational Acoustics’ Smaart real-time analysis features have been integrated into Virtual StudioLive (VSL), which is part of Universal Control. Virtual StudioLive now offers both Smaart Spectra time-frequency spectrograph and real-time analyzer (RTA) views, which are superimposed over each graphic EQ.

The Smaart Spectra spectrograph display can help to precisely identify nasty feedback frequencies, enabling even less-experienced users to easily tune P.A. speakers to the room. Smaart Spectra graphs a continuous series of spectrum measurements, showing frequency on one axis, time on another, and amplitude indicated by colors. This makes it very useful for quickly identifying feedback frequencies, which can be easily addressed using StudioLive graphic EQs.

Universal Control 1.6 adds other useful features, as well. You can now control Talkback on/off and routing with VSL. Version 1.6 also adds support for the new StudioLive Remote 1.3 update (discussed shortly).

Finally, Universal Control 1.6 updates the Windows and Mac drivers for all and StudioLive-series mixers products and for all FireStudio-series interfaces except for the original FireStudio (26x26). This update greatly improves performance, especially on Windows systems. Note that Universal Control 1.6 requires a firmware update to StudioLive mixers.

PreSonus has simultaneously released StudioLive Remote 1.3 for iPad. This version of the company’s wireless mixer-control app adds Talkback on/off and routing assignments and enables Scene recall for hard-disk-based Scenes (but not for Scenes held in mixer memory).

Universal Control 1.6 is a free update and can be downloaded from the Technical Support section of the PreSonus Web site. StudioLive Remote 1.3 is a free download from the Apple App Store.

Zeehi’s CueCast Technology Allows File Conversion Between Mixing Console Platforms

Zeehi, an entertainment technology company dedicated to developing solutions to improve the workflow of global entertainment production professionals, has announced the Beta Release of the CueCast Digital Mixing Console User File Conversion Service.

CueCast provides front-of-house and monitor engineers, sound reinforcement companies, broadcasters, performing arts facilities and production managers the ability to quickly and easily convert show files between different digital audio mixing console formats.

The current Beta Release of CueCast converts the most commonly used features and functions including bussing, sub-group assigns, control group assigns, routing, labeling, mutes and mute groups, EQ and dynamic in/out settings, aux. send on/off/and assigns, and effects and matrix on/off and assigns.

Future releases will support additional console platforms, and will provide conversion of variable settings, snapshots, and many other features.

The web-based service solves a fundamental challenge: how to take user settings from one mixing console to another without the time-consuming headache of entering those settings manually.

“Thanks to the console expertise and software savvy of our development team, converting the user data is reliable and takes just three easy steps,” notes Danny Abelson, co-founder of Zeehi. “Simply upload your file to our secure site – http://www.cuecast.com – specify the format you need, and download the converted file for installation in the new console.

“If you like, we’ll store your files on our secure cloud for safekeeping. CueCast technology supports files from 24 to 196 inputs, and the Beta release supports file conversion between the Avid Venue, DiGiCo SD8 and SD10 and Yamaha PM5D platforms. Soon you can expect us to add many other formats and features to the service.”

“We are very fortunate in our industry,” continued Abelson. “The manufacturers have designed mixing consoles with remarkable features and sound quality.

“Unfortunately the formats in which user data is stored in these different platforms are not compatible with one another. Our research with some of the world’s most prestigious sound companies, veteran sound engineers, broadcasters, and leading production managers indicates that this incompatibility results in a significant burden to users.

“For a variety of reasons engineers often need to transfer those settings to a different brand or model of mixer depending on touring conditions, a venue’s installed equipment, or the availability of a particular console.

“These users identified a number of different scenarios, including festivals, touring without a console, change of production truck, unexpected equipment loss or failure, or availability where switching consoles is simply a necessity.”

“The opportunities digital has given us have been remarkable, but with these improvements come greater expectations by performers and management for crews to do more in less time.

“On a surprising number of occasions, digital solutions unintentionally create obstacles for the production team. Our goal is to improve workflow for entertainment industry professionals by streamlining this process, and make changing to another desk fast and easy.”
