Gary Hebert Of THAT Corporation To Present Microphone Preamplifier Design Tutorial At AES

The session is part of the Product Design Track of the 129th AES convention.

THAT Corporation’s Chief Technology Officer, Gary Hebert, aims to unlock the secrets of designing cost effective, high-performance microphone preamplifiers at a tutorial during the 129th Audio Engineering Society Convention in San Francisco.

Mr. Hebert’s tutorial, “Designing Microphone Preamplifiers”, addresses many of the challenges faced in this critical, largely analog part of the audio signal chain.

Hebert will present a sampling of amplifier topologies and circuit details, and discuss design tradeoffs among cost, size, power consumption, noise, distortion, and other factors.

The session, part of the Product Design Track within the AES convention, is scheduled for November 6th from 4:45 to 6:15pm,

“Preferences and opinions on preamplifiers are nearly a religion within the professional audio community where the microphone preamp often defines the signature sound of a piece of equipment or even a recording studio,” stated Mr. Hebert.

“Working in harmony with the microphone, the preamp often sets the performance of the entire system.”

“In addition, as the first line of defense to the outside world, it must withstand hostile conditions such as 48V phantom power faults or erroneously patched hot signals.”

THAT Corporation will sponsor the Product Design Track at the 129th AES Convention, which includes Hebert’s tutorial and 19 other events.

Tech Tip Of The Day: What’s That Buzzing?

Advice on how to eliminate interference from lighting dimmers in your studio.
Provided by Sweetwater.

 
Q: I just finished building my project, complete with some swanky dimmable lighting, and I’m all set to start mixing.

However, there’s a buzz in my signal chain I just can’t chase down. Any advice?

A: Anyone who has ever played a gig at the hotel ballroom has probably fought this battle at one time or another, but it’s really frustrating when it happens in your own studio.

There are several problems that cause this, and usually when it becomes noticeable it’s because more than one of them are active.

The variables are the quality and type of lighting dimmers, the amount of lighting being dimmed (is it one 100 watt bulb or 20 kilowatts of ballroom lighting?), the nature of the electrical wiring, and the nature and quality of the audio wiring.

Lighting dimmers that use big, inductive coils can cause hum to be induced in audio equipment just by being in close proximity.

Dimmers that use potentiometers or solid-state circuits (as many inexpensive home dimmers do) will cause hash noise and other garbage to be induced.

In both cases the induction often occurs through the electrical wiring. Basically, they feed a bunch of garbage back up the AC line (and ground line) and it finds its way into your gear.

Similarly, however, they radiate electromagnetic energy through the air, which means your poor guitar is going to pick it up.

Without getting into an entire electrician’s course on lighting circuits, suffice it to say that the quality of the dimmer and the way in which they are wired is an important variable.

If lighting dimmers put enough garbage into the air and back on to the electrical lines you may be stuck with some of it getting into your audio, but there are some precautions you can take to better your chances. Make absolutely sure you have no ground loops.

A ground loop acts as a big antenna for electromagnetic radiation so your best bet is to not have an antenna.

A power conditioner with isolated outlets will also help, both in preventing ground loops and in preventing general garbage on the AC line from getting to your delicate audio equipment.

Balanced wiring (both audio and electrical) will better be able to prevent problems than unbalanced wiring.

If you solve enough of these problems you should be able to bring the noise under control. If you can’t - and sometimes you just can’t - we suggest not dimming the lights.

After all, it’s not a perfect world folks.

As always, we welcome input from the PSW community and would love to know how you would (or have) handle lighting levels in the studio. Feel free to let us know in the comments below.

DPA 4099 Clip On Microphones Amplify The String Section Of Sting

The 4099 is a new favorite of FOH Engineer Howard Page who is a fan of the absolute separation provided by the microphone.

Sting’s front of house engineer Howard Page is using a large quantity of DPA 4099 clip mics across the string section for Sting’s Symphonicity word tour.

Accompanied by a full symphonic orchestra, Symphonicity sees Sting performing new arrangements of his greatest hits as well as more unknown work.

Page, senior director of engineering at Clair Brothers, was approached to handle FOH for the tour due to his extensive orchestral experience.

Familiar with DPA microphones from Sting’s cathedral concerts last winter, Page was delighted with the 4099s purchased by Clair Brothers for the tour.

The entire string section - nine first violins, seven second violins, seven violas, five celli and three basses - is miked with 4099s, with several more on radio packs for clarinet and trumpet soloists.

Page has veered away from the traditional area miking method of amplifying an orchestra, where mics were shared between two chairs or desks.

“The problem with that is the moment you add even a semi-rock group to a symphony orchestra, the inherent dynamics between the two are so out of balance; the natural volume that a violin puts out compared to what a guitar or a drum puts out is so wildly different,” explains Page.

“The DPAs are the best mics I’ve ever, ever found - and I’ve been doing this a long time with orchestras. They give me absolute separation: when I turn on a DPA 4099 on one violin I get one violin and barely anything else, which gives me incredible signal to noise.”

“I also get more headroom on an overall string session than I’ve ever had on an orchestra before; traditionally you’re up against a feedback threshold, and your show is compromised by how loud you can go.”

“But the DPAs are so immediate that by clever use of overall reverb, I can move sections forward to get more presence for certain songs, or more natural reverb across them all.”

Over time, the show has evolved to become more rhythmic. “Sting’s getting the percussionist to play more back beat, and If I didn’t have the DPAs I’d frankly be dead in the water by now,” says Page.

“We’ve done all sorts of venues on this tour, including 40,000-capacity outdoor stadiums, the notoriously tricky Albert Hall and the reverberant Metropolitan Opera which is not designed to have microphones, and I couldn’t have done them with area miking, it doesn’t work.

“The beautiful thing about using the DPA 4099 is you turn it up and it sounds like a violin. The old contact mics didn’t give you the true texture of the violin sound, it gave you an edgy, screechy sound that you had to murder with EQ.”

“I place the 4099s on the F hole on the top side of the violin, turn them up with no EQ, and they sound exactly like listening to the instrument. One of the most difficult challenges of doing this is instantly removed.”

“Word about the DPA 4099 is, believe me, getting around,” he says. “Everyone raves about how the strings sound on this show, and the reviews all mention how rich the orchestra sounds.”

Deploying New Concert Technology At Rogers Bayfest

The multi-weekend festival which saw audiences of up to up to 20,000 per show utilized several impressive sound systems deployed by Showworks.

The annual Rogers Bayfest music festival has grown from humble roots since it’s founding over a decade ago with just a single performance to currently spanning two consecutive weekends where more than 100,000 attendees are treated to shows by top artists and numerous emerging acts.

Hosted in its original beautiful setting of Centennial Park in downtown Sarnia, Ontario, Canada, on the southern banks of Lake Huron, the 2010 version of the festival set a new high in terms of number of performances.

The first weekend offered rock headliners such as the Scorpions, Rush, and Weezer, followed by a second weekend of country that included top artists like Keith Urban and Alan Jackson.

And this year for the first time, it was all capped by yet another performance day featuring The Black Eyed Peas.

Bayfest is not only one of the largest tourist attractions for the area, but is also one of its biggest economic stimulators.

In fact, it was named the Best Business/Event Of The Year for 2009 by the Ontario Tourism Council.

Founded by the late Jim Stokely and still under the direction of his wife Michelle, it is a non-profit endeavor, with all proceeds going back into the community.

Equipment racks.

Sound reinforcement for Bayfest was supplied by Showworks, a fast-growing production and system installation company based in Mississauga, Ontario.

Showworks, which also provided lighting, video and other production for the second consecutive year, is headed by veteran touring mix engineer Geoff Kent.

In addition, Rob Deslauriers of SF Marketing of Canada lent his talents to the sound system design.

The large main stage, owned by the festival organization, hosts all performances. It’s the focal point of a huge lawn extending well over 600 feet back that hosts audiences of up to 20,000 per show.

Geoff Kent of Showworks, sound provider for the event.

For the first weekend, Showworks chose to utilize two EAW KF760 large-format line arrays, flown to each side of the stage, to provide primary coverage, but things changed notably on the second weekend, with the sound team deciding to deploy the recently introduced EAW KF740 line array modules as the mains.


The KF740 delivers output resembling the much larger KF760, but at a muchreduced footprint and lower weight. Each module incorporates eight drivers (four- 10 LF, dual-8 MF and dual-1.4-in-exit HF) into a cabinet measuring just 13 inches high by 40 inches wide.

A symmetrical design, large horn and spaced woofers foster broadband pattern control, and the system can be further optimized with the company’s Focusing processing and Resolution software. KF740 modules can also integrate with KF760 or KF730 arrays for additional flexibility. (For more about the KF740, see Designer Notebook in the April 2010 issue.)

“This was our first real-world application with the KF740, and it couldn’t have gone any better,” Kent states.

“There have been just a couple of times in my entire career where I’ve developed a whole new level of respect for PA rigs, and this is one of them.

The thing that stands out the most is the compact footprint of the box versus its output, combined with a full, rich sonic quality.

It’s just incredible. I’m a true skeptic, but this is the real thing.”

The main arrays each incorporated 10 KF740 modules, with four KF760s at the top to add a bit of high-frequency boost to the very back of the coverage region.

In addition, the arrays weren’t configured in the usual “J” shape, but rather, were set up to provide more of a flat-front array due to the throw distances involved.

“One of the great things about the festival this year is that it gave us a nice comparison, with KF760 arrays the first week followed by KF740 arrays in the same space,” Kent adds.

“With the KF740s, we literally attained the same coverage and SPL (as the KF760s), and what really stood out is a more ‘hi-fi’ sonic signature of the newer arrays.”

A view showing the large scope (and coverage area) presented by Bayfest.

Both weekends, the main arrays were flanked by six flown Meyer Sound M3DSub subwoofers, loaded with dual-18 and dual-15 woofers that are configured to supply cardioid characteristics for additional control of low-frequency energy.

On the ground, 24 Canadian Speaker Works Pro (CSW Pro) Black Box dual- 18 hypercardioid subwoofers in front of the stage supplied a low-end hammer when needed.

“The CSW Pro is the loudest, angriest subwoofer this side of Servodrive that I’ve heard anywhere,” notes Deslauriers.

Front fill and out fill to the very front and side areas came courtesy of eight KF761 wide-coverage modules placed atop the subwoofers.

All main system loudspeakers and subwoofers were driven by QSC PowerLight 3 Series power amplifiers, with PL380s the predominant choice except for high-frequency drivers, which were powered by a combination of PL340 and PL325.

Five EAW UX8800 units (each 4-in by 8-out) provided both loudspeaker and overall system processing, as well as facilitating more advanced tailoring with EAW Pilot software linked in via PC.

The UX8800 processors were all networked, allowing control and monitoring from the house mix position. The sound team notes that the networking, employing the latest version of EAW U-Net firmware, proved exceptionally stable and user-friendly.

“I really like to focus on sound and don’t get all that excited about networking, but I have to say that the networking here was beyond impressive,” Kent states. “It was really dialed in. It’s obvious that EAW has put a lot of time and care into this.”

Two delay zones helped solidify coverage, in particular bolstering high-frequency support. Each zone incorporated EAW NTL720 compact, self-powered line arrays both flown at about 200 feet and 400 feet from the stage, behind the house mix position. And, both of these arrays were also incorporated on the system-wide network.

One of the EAW KF740 main arrays - topped by KF760 modules - with a relatively flat-front configuration, and next to flown Meyer M3D-Sub subwoofers.

Showworks had a Yamaha PM4000 console at the ready for any acts that needed it, but the vast majority brought in their own consoles for both house and monitors.

The same with effects devices. Consoles and outboard gear could be patched in quickly via a Midas XL88 line level 8 by 8 matrix mixer.

“Festivals are all about quick changeovers between acts as well as being able to accommodate the needs of every artist and guest engineer. That was the driving force of our efforts on both weekends, and it all happened seamlessly,” Deslauriers says.

For Kent, a highlight was the final concert by The Black Eyed Peas, a band he’s worked with extensively in the past. “They put the pedal to the metal, really pushed it in terms of dynamics, and the engineer produced a great mix,” he concludes. “It was a demanding test for any array, let alone a new one you’re just getting a feel for, and it stood up really well, passing with flying colors.”

What You Need To Know When It Comes To Mixing Wedding Music

Technical know-how and art must come together when it comes to weddings. Are you prepared?
This article is provided by Behind The Mixer.

 
Getting out of my car on the way to work a wedding, I thought to myself, “This is going to be one hot service.” 

And not for the reason you might be thinking, either. 

This bright August day, the sky was clear, the sun was directly overhead, and I was headed to an outdoor wedding. 

In retrospect, I was much more fortunate than the groom and his entourage who were decked out in the 87 layers of rental clothing that come with wearing tuxedos. 

It’s not that I’m against outdoor weddings.  Jesus performed his first miracle at a wedding turning water into wine.  Ten bucks says it wasn’t Beringer White Zin, either. 

Heck, I’d bet the first outdoor wedding would have been between Adam and Eve had only they been able to find a reception hall with a disco ball. 

But that’s not why I’m telling you all of this.

Sitting in the amphitheater, hoping my sweat wouldn’t soon change the color of my shirt, I eyed the sound system. 

It was a portable Fender unit with a few line inputs and outputs and speakers on pedestals - acceptable for the small venue. 

The sound guy was the brother of the bride and currently had the job of controlling the wedding music.  Let’s call it an iPod wedding and just get that out of the way.

The wedding was nice, and everything went smoothly - no feedback issues that I’ve seen in the outdoor environments. 

I remember one wedding where the microphone was directly in line with both loudspeakers - feedback wasn’t a problem at that wedding, it was part of the wedding. 

I’m writing all this just to build up to a cental point when it comes to wedding music; technical know-how and art must come together when it comes to weddings absent of any musicians and where it’s up to the sound operator to provide the music.

Great music performances flow from one song to the next.  There are even albums with little-to-no delay between songs. 

I’m not saying silent space can’t occur between songs but there is a time and a place for everything. 

Running sound for an event like a wedding might mean we are charged with playing music before, during, and/or after the wedding. 

I submit to you that we are responsible for more than just playing the music but blending it and playing it so it flows.

A perfect example is switching from one song to the next.  There are a few ways this can sound badly.

• The song ends and the audience hears the CD player open, close and then the next song starts - because the music is from a stack of CD’s.

• The song starts to fade out and then suddenly stops and the next song plays.

• The song fades but the time between when it fades out of the audience’s ability to hear it and when the next song starts is greater than five seconds.

 
Just because we aren’t mixing a band, it doesn’t mean we can’t mix recorded wedding music.  There are a few options available.

• Using CD’s, use two CD decks to cue up and blend the music.  That’s basically a DJ setup. Use the faders to fade in out songs as appropriate.

• Get the music way before the wedding and create a mix CD (or computer file if you can play that way).  This way, you can create a mix with the proper timing between songs.

• Whatever you do, don’t just kill a song - fade it out if you have to.

 
Remember, wedding music carries emotion.  When the time between songs is too long or songs end suddenly, listeners can tune out of the mood which the music is trying to set. 

I want the father-of-the-bride to be thinking about the beauty of the wedding.  I don’t want to give him the opportunity to think about what he has to do tomorrow.

What Bad Wedding Audio Experiences Have You Witnessed?  What Wedding Audio Advice Can You Share? Let us know in the comments below!

D.A.S. Audio System Chosen By Vineyard Church Of Columbus

A variant line array system was deployed in the newly remodeled sanctuary.

With a congregation of approximately 8,000, Vineyard Church of Columbus is the largest church in Central Ohio.

While it offers hundreds of ministries and thousands of volunteer opportunities to its congregation, Vineyard Columbus works very hard to be a ‘small’ church where members won’t get lost in the shuffle.

The church recently completed a dramatic overhaul of its multipurpose room and, in an effort to provide the very best audio quality throughout the space, installed a new sound reinforcement system drawn from the catalog of Valencia, Spain-based D.A.S. Audio.

Co-owned by Ed Whitney and Mike Hockenberry, Reynoldsburg, OH-based Metro Audio Video, LLC was contracted to design and install the church’s new sound system.

Metro Audio Video is a design build firm for sound, video, and lighting with a significant presence in the church, corporate AV, and education markets.

The sound reinforcement system that Whitney ultimately deployed consists of eight D.A.S. Audio Variant 25A powered, two-way mid-high line array elements, two Variant 18A powered subwoofers, plus three AX-V25 steel bumpers to hang the system.

“Vineyard Columbus’ multipurpose space is used for everything from meetings and banquets to small concerts,” said Whitney.

“When the church decided to renovate, they wanted to get away from the look of a gymnasium. Hence, they erected a multi-level stage area and they didn’t want big, unsightly loudspeakers to overwhelm the room and interfere with the line of sight. Aesthetics were very important.”

Whitney continued, “The room is approximately 90 feet by 75 feet and has a drop ceiling. The space is structured such that it is wider than it is long—with the stage / altar area facing into the width of the room and the FOH (front of house) mix position situated along the opposite wall.”

“There is some acoustical wall treatment in addition to carpeting. Moveable seating for approximately 900 people is used. Music plays a vital role in the church’s worship service and there is both a praise band and a large, 150-voice choir.”

“For these reasons, we had to find a loudspeaker setup that provided solid music reproduction, a high level of speech intelligibility, and wide dispersion. Most significantly, large, unsightly loudspeakers were out of the question.”

“The D.A.S. Variant loudspeakers are compact, self-powered, and have excellent flyware,” said Whitney. “Since there was no room for the subwoofers under the stage area, the fact that the Variant system places the 18A sub at the top of the cluster proved to be exactly what we needed.”

“The system is flown at approximately 15 feet and I was particularly impressed with the ease of interconnecting the system. After installing the AX-V25 bumpers, the subwoofer and the three elements all clip together. The setup is small and light, yet provides a full, rich sound that creates even coverage throughout the space.”

Vineyard Columbus’ new system was installed in May 2010 and placed into service in early June. “We arranged a demonstration of the system during the consulting phase of the project and Carlos Henao, D.A.S. Audio of America’s U.S. Accounts Manager, came out to us, ground stacked a demonstration system, and did a terrific job pointing out the features and benefits of the equipment. His efforts really helped seal the deal,’ said Whitney.

With the system fully operation, Byron Houchins, Vineyard Columbus’ Director of Media, reports that everyone at the church is very pleased. “We are extremely happy with the performance of the D.A.S. system,” said Houchins.

“The sound quality is excellent and consistent no matter where you happen to be seated in the room. Equally important, the loudspeakers aren’t visually distracting. This is the best sounding system we’ve ever had.”

Ashly Processing & Amplification Chosen To Refresh Japan’s Ryokaku-Ji Temple

Masaki Morimoto designed the new cost-effective system for Japan’s Ryokaku-ji Temple which is based uponthe Ashly ne8250pe eight-channel amplifier with DSP.

Ryokaku-ji Temple is located in Tsuruga, Fukui Prefecture, three-hundred miles west of Tokyo in central Japan.

Although it was founded nearly five hundred years ago – literally centuries before the advent of sound reinforcement – Ryokaku-ji Temple has never hesitated to embrace new technologies.

When the temple moved to a new building fourteen years ago, it installed a sound system for the 100-seat hall of worship that promised clear speech and moving music reproduction.

However, much to the disappointment of the family that owns Ryokaku-ji Temple that promise was never delivered. Speech sounded boxy and music dribbled out, drained of its vitality.

EMU and ENU, a nearby Tokyo-based pro audio sales and sound reinforcement integrator, came to the rescue when the family had finally had enough.

Company president Masaki Morimoto designed a new cost-effective system centered on the powerful processing and robust performance of an Ashly ne8250pe eight-channel amplifier plus DSP, combined with an Ashly WR-5 remote controller for intuitive user control.

The new system consists of six loudspeakers and one subwoofer. A stereo pair of One Systems full-range boxes is located where the ceiling meets the wall above the main riser, and four Tannoy ceiling speakers distribute audio over the seating area.

Morimoto built a subwoofer to specification for the temple. He custom-sized the dual five-inch to fit under the furniture in front of the statue of Buddha.

“I wanted to deliver a reliable, long-lived system that would sound full and musical,” said Morimoto. “In addition, the system had to be compact and cost-effective. In my pro audio experience, which is now stretching into its fifth decade, the Ashly products represent a unique combination of performance, reliability and economy.”

“I was confident that the two-rack space Ashly unit would result in the improvements that the owners were expecting.”

The inputs to the system consist of four wireless microphones, two wired microphones, a CD player, and a DI from an electric organ. The microphones are used primarily for the sutra of a few priests and the spoken word of a sermon on the weekends.

The inputs feed a TOA 12-in/2-out analog mixer, which in turn feeds the Ashly ne8250pe. With the easily-connected Ashly WR-5 wall remote control, users can control the overall volume and select between speech and music modes, which reconfigure the loudspeaker’s relative volumes and equalization.

Morimoto made good use of the Ashly ne8250pe’s integrated DSP, which contains a well-implemented list of processing modules that are available in any custom configuration via easy-to-use software.

“The sound quality is now perfect for both speech and music reproduction,” enthused Morimoto. “The family that owns Ryokaku-ji Temple is very pleased.

We’re now drawing up plans to revamp the sound system in their early-childhood education wing. Once again, Ashly Audio’s technology will form its core.”

Electro-Voice Loudspeakers Deployed In Force For Film Premiere At Fenway Park

The key technical challenge for the system, which was modeled by Michael Rome of BLS using Electro-Voice Line Array Prediction Software (LAPS), was to recreate both the power and the nuance of the soundtrack in a setting designed for baseball rather than sound

“A lot of people dream of hitting a grand slam in Fenway, but we actually did.” That’s how Larry Habetz, founder and owner of Southwest Louisiana’s Gulf Coast Sound Productions (GCS), describes the experience of deploying a sound system incorporating more than 100 Electro-Voice loudspeakers at Boston’s Fenway Park for the premiere of the new Ben Affleck film The Town.

Specifically, the system included three line arrays, surrounds, and a large complement of subwoofers, helping to project the 5.1 channel soundtrack’s clarity and dynamic range while bringing home the full impact of the movie’s action.

When the film’s producers settled on the premiere’s unconventional setting, event projection specialists Boston Light & Sound (BLS) were brought in to oversee technical aspects of the screening. “We actually like going into places where people think you can’t do a good job showing a movie, and Fenway Park was one of those,” says Chapin Cutler of BLS

BLS specified an Electro-Voice line array system to cover seating for about 2,500 behind the third-base dugout. “A decade ago we worked with the late Monte Wise at ShoWest on what was probably the first use of a line array for Dolby Digital theatrical playback,” Cutler says, “and ever since then we’ve been using Electro-Voice arrays whenever we can. The pattern control we get with these arrays means that we can control sound levels very precisely from front to back and deliver superior intelligibility across a large area.

“So we’ve been a believer in EV speaker systems for many years, and we selected Gulf Coast because they are an EV provider and we knew from previous experience that they are a terrific company to work with.”

The key technical challenge for the system, which was modeled by Michael Rome of BLS using Electro-Voice’s Line Array Prediction Software (LAPS), was to recreate both the power and the nuance of the soundtrack in a setting designed for baseball rather than sound.

“Movies are very dynamic,” says Habetz. “You touch on so many different aspects of the audio range, from mild to wild, from a whisper to an explosion.” Because of this sonic variety, soundtracks can reveal a lot about loudspeaker capabilities.

“Some company’s boxes sound great doing a particular style of music, like rock and roll, because their characteristics complement those kinds of sounds,” he adds. “But there may be other types of sound that they don’t handle as well. For a movie, your speakers have to be able to do it all. They have to be able to reproduce all the dynamics as accurately as possible, and to shine in all aspects.”

The specifics of the system configuration were largely driven, Habetz explains, by the goal of providing the most even coverage from the front seats to the back, as well as the requirement for at least 20 dB of headroom above the nominal theatrical-standard operating level of 85 db SPL. “They want the ability to provide that dynamic range without stressing any components in the signal chain.”

The left, center, and right channels of the soundtrack were handled with three line arrays, each composed of 12 XLC127DVX three-way, high-output compact line-array elements. oversaw the crew “We had to build a grid over the third-base dugout, and each box had to be lifted up there before being flown. If the boxes were big and heavy, or the rigging wasn’t user-friendly, it would cost us in time and labor to put up those arrays. So we chose XLC127s for their intelligibility and ease-of-rigging, and because they pack a lot of horsepower in a small size. We’ve had a great return on our investment in those boxes, because EV designed them with upgradeable electronics, so even the first units we purchased seven years ago are still cutting-edge technology today.”

For the low end, the system combined 16 Xsub dual 18-inch subwoofers with 24 XLC-118 high-output subwoofer line-array elements that Habetz says were “used as a kind of bridge between the 12-inch drivers in the XLC127DVXs and the dual-18s in the Xsub.” With a total of 56 18-inch drivers stacked behind the screen, he adds, “we moved some substantial air. The impact was huge — you could feel the park literally shake during the explosions - so it really had that larger-than-life, Hollywood feel.”

For left and right surround channels, 24 XLE181s were deployed in groups of four at three locations on each side of the seating area. “We wanted nice dynamics with controlled coverage to get a smooth transition from the closest seat to the farthest. And we needed something that was light but with good horsepower. The XLE181s are only 38 pounds, but they have a lot of bang for their size and a lot of bang for the buck. So it worked out great.”

Overall installation coordination for the undertaking was provided by Celine Larimer with the assistance of Daniel Beedy, both from BLS. As a sound engineer and the technical liason for the project, Larimer was able to coordinate the efforts of all parties in the project with the many departments at Fenway Park.

“When dealing with an historic structure like Fenway, and the huge concern for protecting the ball field itself, the logistics for this project were daunting,” Larimer says. “Because of our long standing relationship with the Park, we were able to work with them in hanging the surround arrays from the roof overhang and bring a level of comfort to the Park management,” she adds. It is believed this event was the first time a film has ever been run in Fenway Park.

To power all these loudspeakers and maintain the required headroom, the system incorporated 60 Electro-Voice P-RL amplifiers. “We have been using these amps for years, largely for outdoor festival work.” Habetz says. “They bounce around in the back of the truck and they are very robust on the road. But they also deliver a lot of dynamics with very low noise. The movie people were really on the lookout for hiss and other noise, but when our rig was fired up they walked around and they couldn’t hear anything.”

The amps’ on-board DSP was used for limiting and some time alignment, while the rest of the system processing, including FIR filtering to optimize the signal for each speaker model, was applied via an Electro-Voice NetMax N8000-1500 digital matrix controller.

“NetMax is phenomenal,” Habetz says. “It does so much, and we’re not even scratching the surface of what it can do. We have a tablet computer attached to the NetMax via WiFi, and after it rained and there was some concern that the sound had changed, we were able to remotely pull up the real-time status of each amp to show that the system was operating normally, and that the change was due to water on the perforated screen.”

With the integration of NetMax support across a broad spectrum of components, Electro-Voice has made it easy for companies like GCS to stick with a familiar, consistent solution for a wide variety of situations. “100 percent of our speakers and 98 percent of our amps are EV,” Habetz says. “Getting it all from one manufacturer is a huge advantage. If you have a problem you don’t have to call five different places. With EV, you have a single source, and all the engineering staff works together to help you. They know you, and they treat you like part of the family. That kind of relationship is very important to the success of our business.”

L-Acoustics dV-DOSC Installed In Qatar Nightclub

The venue’s architecture is unusual making the system design a challenge.

An L-Acoustics system has been installed into SEVEN, the new club at La Cigale Hotel in Doha, Qatar, supplied by L-Acoustics Certified Provider Venuetech.

The 1,000-capacity oval-shaped club has been installed with an unusual sound system based around a stereo configuration located in front of the DJ booth.

This consists of two hangs of four dV-DOSC cabinets focused on the dance floor and four hangs of three ARCS medium format line source cabinets to cover the table areas around the dance floor. A further system of six distributed 12XT coaxial boxes cover a pillared area.

The club also features an unusual sub bass setup of six SB28 subs in a horizontal ARCS/SUB configuration, to deal with the very wide shape of the venue. This provides consistent sub/low frequency coverage all around the room.

The DJ, VJ and LJ all have personal monitoring systems of 12XT coaxials, and the entire system is driven by LA4 and LA8 amplified controllers, monitored by the L-Acoustics Network Manager remote control software.

“The venue’s architectural shape is unusual and the design of the system was a big challenge,” said Venuetech’s technical director Elie Khairallah.

“The result is phenomenal and the sound quality, along with SPL levels that system can provide, is excellent. All of the gear was installed in a very short time and setup of the system was accomplished in just two days.”

The club opened in late September to great acclaim, with a set by French DJ David Vendetta, and an audience who were delighted and astonished by the sound system and entire setup.

Simple Fixes Which Can Save A Recording Session

Though major pieces of gear can certainly fail, often it’s a simple fix that gets an operation up and running again.
This article is provided by the Fisher Creative Group.

 
Uh-oh… You’r recording and all of a sudden there’s an audio problem.

Now what?

When you are right in the heat of recording – whether in the friendly confines of the studio or on-location, some critical piece of gear is bound to fail at the most inopportune moment.

A mic may stop working, the mixer may hiccup, the recorder may have issues, et al.

It’s oh-so-easy to get flustered when several people are staring you down as you frantically try to hunt down the problem(s) and try to fix it fast.

But, before you go any further, take this short quiz:

It’s almost always the ______________________.

The answer to that question 99 times out of 100 is:

It’s almost always the cheap thing.

Of course it’s possible for major parts of your rig to be at fault. After all, mics can and will fail, mixers can go haywire, and the recorder can stop … er … recording.

However, often it’s a simple fix that gets an operation up and running again.

For example, more often than not the cause of an inability to pass signal is something seeming simple like a bad XLR cable, a dead battery, an errant switch, or simply operator error.

So, step back and work through the cheap things first (not just those shoddy cables you just purchased, though they could well be at issue) to see if that’s where your problems lie.

Swap out cables, replace the batteries, check all the switches, and make sure you’re not overlooking something stupid that you did or are doing wrong.

If you can always remember that little adage, you’ll be back working with your audio quickly (and usually less expensively).
