OPTOCORE TECHNOLOGY SUPPORTS AUDIO FOR THE 2013 U.S. PRESIDENTIAL INAUGURATION

Maryland Sound International Utilizes Optocore Network Rings for Signal Distribution and Monitoring

WASHINGTON D.C., FEBRUARY 19, 2013 – When audio integrator Maryland Sound International (MSI) was once again tasked with supplying the main audio system for President Barack Obama’s second presidential inauguration on January 21, 2013, the company employed two Optocore Networks. MSI, a longtime user of Optocore technology, a leading choice for powering professional audio, video and data transmission networks in a variety of markets, including broadcast, post production and AV, chose the networks for their multiple levels of redundancy and reputation of superior reliability. This marks the third presidential inauguration in a row for which MSI has chosen Optocore equipment for the critical audio distribution.

With the ceremony taking place on the grounds of the Capitol in Washington, D.C. in January, MSI was faced with unpredictable winter conditions as well as a long transmission path back to MSI’s Front-of-House position, nearly 2,000 feet from the last speaker tower. MSI and audio designer Patrick Baltzell needed a way to distribute audio signals with as few conversions as possible in order to ensure the approximately 1,000,000 attendees of the ceremony heard every word.

MSI chose Optocore Network technology in order to drive the signal chain directly from the Yamaha PM5D FOH mixing console using Optocore YG2 Yamaha cards that were connected with redundant fiber cabling to the locations of the loudspeaker processors and amplifiers. This provided MSI with lossless digital transmission, which is critical in order to properly transport the audio with crisp sound and clarity over such a long distance transmission path without any glitches.

“The Optocore Networks we put in place for this year’s ceremony certainly made access to all of the amplifiers, signal processors and overall signal distribution far easier and more reliable than in the past,” says Brian Bednar, system technician, MSI. “This time around, everything was more streamlined and faster to set up and tear down at the end of the event.”

The main Optocore Network consisted of one YG2 card in the Yamaha PM5D FOH mixing console connected to an Optocore DD32 networked AES/EBU device on stage right and another DD32 on stage left. Each DD32 was connected to an Optocore X6P-8/8 analog converter and a Dolby DLP loudspeaker processor via AES. The X6P converters gave MSI the ability to feed all the devices that were not AES and/or not driven through the Dolby processor units.

The second Optocore Network consisted of one YG2 card in the PM5D connected to an Optocore DD32R-FX networked AES/EBU device at delay zone 1 (700 feet away) and another DD32R-FX at delay zone 2 (1500 feet away). Each DD32R-FX was connected to an Optocore X6P-16IN analog converter and a Dolby processor via AES. Both networks featured redundant fiber connections.

The DD32R-FX proved to be a helpful add-on for this year’s sound system, with its built-in network wide Ethernet switch. The Optocore Network allowed MSI an easy access to the Dolby DLP loudspeaker processors and amplifiers located off the main site. With a broad part of the sound system offsite, it was then easy to maintain control and monitoring of all the devices on the network to see if they were functioning to MSI’s specifications.

“It is my role to help the FOH engineer tune the system, so having access to all parts of the system at all times in order to make changes without my needing to leave the FOH position is invaluable,” says Art Isaacs, project manager, MSI. “The X6P-16IN converters gave us the functionality to run measurement microphones from multiple city blocks away back to the FOH position. Using the Optocore system proved itself to us in many ways. The sound system was extremely quiet due to the all-AES based drive system. Ethernet access to all of the online devices proved extremely helpful and provided great flexibility. I can only hope that in 2017 that we can continue to work with Optocore systems and further enhance the sound system.”

The relationship between Optocore and MSI goes back for almost a decade. “Optocore has been part of MSI’s rental inventory since 2004,” says Tine Helmle, director, Optocore. “We are proud to provide MSI with the solutions it needed to ensure the audio was heard loud and clear during such an important and historic U.S. event as the presidential inauguration. We look forward to working with them well into the future.”

HARMAN’s BSS Audio, Crown and Soundcraft Take Pole Position at New Circuit of the Americas Grand Prix Racetrack

AUSTIN, Texas — It’s enough to set any motorsports enthusiast’s pulse racing – the newly completed Circuit of the Americas (COTA) is the first purpose-built Grand Prix racetrack in the U.S. The complex hosted the 2012 Formula One United States Grand Prix, and upcoming races will include the MotoGP, FIA World Endurance Championship and American Le Mans Series. The 300-acre Austin, Texas facility is built around a state-of-the-art 3.4-mile circuit track with a capacity for 120,000 fans. An integral part of COTA is its public address and Emergency Communication System (ECS), featuring HARMAN’s BSS Audio networked digital signal processors and Crown power amplifiers which also receive input from the venue’s Soundcraft mixing console to serve a variety of sound reinforcement needs throughout the venue.

“Although the audio system is used for announcements and music during races and other activities, a facility like Circuit of the Americas requires an emergency notification system that meets public safety requirements as mandated by the National Fire Protection Association,” explained Brian Elwell, senior consultant and vice president of design firm Acoustic Dimensions (www.acousticdimensions.com). “The system has to serve as both a PA and an Emergency Communication System.”

“For 51 weeks out of the year COTA is used for purposes other than auto racing, so the audio system also needs to be suitable for concerts, events and activities throughout the entire facility, both indoors and out”, emphasized Elwell. “The Soundweb London network is an integral part of making everything work, acting as a core system that runs all audio signals everywhere including emergency notification to the 20,000-seat amphitheater and 40,000 people in the Grand Plaza area. As an example, we can instantly switch from using the PA system as a music source for a selected area in the complex to taking a single emergency paging mic and feeding it everywhere in the facility in case of a facility-wide emergency. We also have redundant signal paths to all audio components in the system to make sure everything is online, all the time.”

The project required that audio processing and amplification be installed in more than 30 different rack locations around the track as well as the grandstand, pit building, Grand Plaza indoor facilities and COTA’S Tower Amphitheater. A Soundcraft Si Compact 16 digital mixing console with CobraNet™ option card is used to mix various audio sources and integrate the console’s audio outputs with other components in various parts of the installation. CobraNet-compatible BSS Audio signal processing includes seven BLU-800 processors, two BLU-320 and six BLU-120 input/output expanders, three BLU-80 processors and 13 BLU-32 input/output expanders. The system also includes six BLU-10 programmable controllers. Matched to different loudspeaker zones and requirements, more than 70 Crown amplifiers are installed throughout Circuit of the Americas, including CTs 1200 USP4CN, CTs 4200A, CTs 3000 LITE, CTs 2000 LITE, CTs 1200 LITE, CTs 600 LITE, MA5000i, and 1160A models.

“We chose Crown power amps since their onboard DSP is extremely effective, and they work hand in hand with BSS components via HARMAN HiQnet™, noted David Battershell, project engineer for Ford Audio-Video Systems (www.fordav.com). “And in our experience the BSS Audio Soundweb London system enables designers and installers to provide an audio networking and processing solution for large-scale facilities at a price no other system can match. HARMAN’s HiQnet networking protocol links it all together and provides real-time monitoring status for all of the Soundweb London processing, Crown amplifiers and loudspeaker cable runs around the track. This ensures the system meets the emergency communication system standards as specified by the design team.”

HARMAN (www.harman.com) designs, manufactures and markets a wide range of audio and infotainment solutions for the automotive, consumer and professional markets – supported by 15 leading brands, including AKG, Harman Kardon, Infinity, JBL, Lexicon and Mark Levinson. The company is admired by audiophiles across multiple generations and supports leading professional entertainers and the venues where they perform.

Martin Audio MLA Covers Wide Range Of Venues On Killers Tour


The recent Killers U.S. tour presented a unique set of challenges for Delicate Productions.

Besides the need to provide consistent coverage in radically different venues ranging from mid-sized arenas to small theaters, casinos and ballrooms, the Camarillo, CA-based production company had to contend with cancellations of major arena shows at New York’s Madison Square Garden, Toronto’s Air Canada Centre and New Jersey’s Susquehanna Bank Center due to lead singer Brandon Flowers’ laryngitis.

That said, the tour was still well received by enthusiastic fans and media, earning praise from Rolling Stone magazine for its “thunderous, meaty sound” at the tour opener in Denver’s 1stBank Center.

The successful six-man band that formed in 2001 and consists of front man Flowers who also doubles on keyboards, Dave Keuning (guitars), Mark Stoermer (bass), and Ronnie Vannucci (drums), was supplemented by two multi-instrumentalists for this critical tour to support their popular Battle Born release.

Delicate actually picked up the tour from Capital Sound in the UK, making a seamless transition in terms of coverage, audio quality and impact. Asked if the systems were similar, Killers Front of House Engineer James Gebhard said, “Absolutely identical. Capital and Delicate worked really well hand in hand. We did some fine-tuning of the system in the UK and Capital communicated directly with Delicate about the details so they could be set up exactly the same. It was a very quick transition from one to the other.”

A veteran engineer who worked his way up from university amateur shows through a variety of bands to the highest level of touring, the Manchester-born Gebhard has been with the Killers since 2004. He had been using other line arrays before the tour, but Delicate was instrumental in getting him onboard with the Martin Audio MLA system.

As described by Delicate’s Smoother Smyth, the process involved several steps. “Once we had teamed with our friends at Capital for MLA,” Smoother recounts, “we got James to see the system in action in the UK and at a Zac Brown Band show in Indianapolis. We then brought him in to our warehouse to discuss MLA theory and spend some hands-on time with the system before he signed off on MLA for the tour. Needless to say, it worked out really well in the end for everyone involved.”

The touring setup included 14 MLA cabinets and two MLD down fill cabinets per side for the main PA; 12 MLA cabinets per side for the side hangs; 20 MLX subwoofers ground-stacked in a cardioid broadside array in front of the stage along with four MLX flown per side to fill in those areas. I10 Martin Audio W8LC cabinets along the stage edge are used for in fill.

In addition to MLA, Gebhard relied on his “ever-trusted” DiGiCo SD7 console with two 56-channel DiGiCo SD racks stage running at 96 kHz along with Waves SoundGrid processing and plug-ins. A variety of microphones were used, starting with a Shure SM58A for lead singer Flowers to a mixture of Shure, Audio-Technica, Sennheiser and E-V, depending on what worked best for the job.

Asked about his maiden voyage with MLA during this critical tour, James was typically candid, “Smoother had to go out of his way to convince me to switch to MLA, but once I was able to work on it, I was amazed.

“One of the most impressive aspects is the phase coherence,” he explains. “Walk the room and everywhere you go it sounds exactly the same. It’s like an audio guy’s dream. You don’t have to start making compromises or second-guessing yourself, searching for holes in the coverage between PA points or the back and front of the room. You can’t believe it actually does what is says it does.”

MLA’s scalability also proved to be very useful for this tour, especially given the radical differences in sizes from venue to venue. As Gebhard points out, “With typical line arrays, you work an artificial X amount of boxes per side to do an arena, but because of what MLA does with all the steering, you can use less boxes for the venue. It all depends on how you predict the room, what you want to do and what the software comes up with. Whether it’s smaller or larger room, you could almost use the same amount of boxes, which definitely makes MLA a very scalable system. And the sound was literally identical everywhere we went, every day. It was fantastic. The pure consistency regardless of the type or size of the room.”

Another useful aspect for Gebhard was MLA’s Hard Avoid feature. “We played around with it a lot during rehearsals in Vegas,” he recalls. “We were in a sound room with very reflective back walls and ceilings so we set it up in there, put on the hard avoids and it made the room sound incredible.

“As far as I’m concerned, Martin Audio has reinvented the wheel in terms of PA design with MLA,” he concludes. “It’s just unbelievable.” The biggest problem Martin Audio has is marketing the product. They really need to get the word out because it’s unbelievable.”

Unfortunately, Delicate was never able to fly the full MLA/MLA Compact system due to the cancellation of the major arena shows. Smoother points out that “it was disappointing that we didn’t get to rig the full system, especially hearing it with the MLA Compacts rigged for rear coverage. But we’ll be using it for the makeup dates in May.”

Pressed for his feelings about MLA, Smyth is enthusiastic but judicious in his response. “I don’t claim to know it all, which is why I surround myself with people who know audio, video and lighting in depth and give in to their wishes. We look at what’s out there in the marketplace, evaluate it and the purchases come on the merits of the product. My guys said ‘MLA is a must-have.’ And even though it’s a challenge because of the cost and complexity of the onboard technology. But at the end of the day that’s what separates MLA from all of the competitive products.

“In the end, I always want to be with the leading edge on anything and everything, and MLA truly is in a class of its own. It’s not just being operational at the flick of a switch; it’s a whole other mindset that represents a new learning curve for engineers that go out with this system. Which means hard work on our part in terms of training courses, the software and hardware updates. We’re dealing with a whole new audio concept, which is very different from anything we’ve worked with before.

“When I worked the MusicCares event with Paul McCartney last February, we deployed MLA and it sounded like a Vegas showroom. And no one thanked us for a job well done because it was just accepted that the room must sound that good. It gives us great satisfaction to provide engineers with such a great place to start from.

“Given the size of the MLA, what it puts out is remarkable and stunning,” Smyth concludes.” It’s a midsized box that can outperform all of the large format cabinets in the marketplace. The fact that I can use it in theaters, hotel ballrooms, casinos, arenas and up, speaks volumes.”

ENTASYS Helps Bring Modern Technology to Historic Church

The rolling hills and fertile farmlands along the Delaware River were among the first to be settled by European colonists, and the area is rich in historic buildings and landmarks. Among them is Alexandria First Presbyterian Church, whose main sanctuary was built in the late 1800s, and is listed on the National Registry of Historic Places.

Despite being one of the older buildings in the area, Alexandria First Presbyterian is all modern on the inside, thanks to a sophisticated audio and video system designed and installed by Blackwood, NJ-based JD Sound and Video. The system includes distributed HD video, with multiple screens throughout, as well as a sound system featuring Community Professional Loudspeakers’ ENTASYS column arrays and VLF Series subwoofers.

“It’s not a large building, and it’s not very ornate,” says JD Sound’s Joe DiSabatino. “But they’ve invested wisely with the technology they’ve installed.”

As DiSabatino explains, the building’s old stone walls and hard surfaces make for a highly reflective acoustical environment, and achieving good spoken word intelligibility has long been a challenge. “It’s a large, boxy room with high ceilings, hard plaster walls, and lots of hard wood,” says DiSabatino. “It sounds great for the choir, but not for the sermon.”

JD Sound recommended a pair of Community ENTASYS column loudspeakers to cover the entire space. “We set up a temporary system for them to use during a service, and they were immediately convinced,” says DiSabatino.

The church uses quite a bit of music in their program, and DiSabatino recommended a pair of VLF208 subwoofers to fill out the frequency range. “We built the subs into the altar, underneath the stage,” he says. “They provide just that little bit of extra low end and kick.”

The ENTASYS also addressed the church’s aesthetic concerns. “The columns are painted to match the walls, and are barely visible,” says DiSabatino. Crown amps power the system, and a Rane HAL system provides DSP and enables the church to make multi-channel recordings of their services, with an eye toward webcasting in the future.

The church’s previous system, a pair of Community CSX loudspeakers, has been repurposed. “The kids have a gathering spot down in the basement, and the original Community system is still working fine, so it was perfect for that,” says DiSabatino.

“The ENTASYS system was the perfect solution,” DiSabatino concludes. “Coverage is consistent to every seat, even under the balcony, and we’ve got far more gain before feedback. And they sound terrific.”

Factor TC’s HARMAN Professional Solution for Bulgarian Amphitheater

NORTHRIDGE, California – Situated close to the Bulgarian seaside town of Varna on the Black Sea coast, a new 2,000-seat amphitheater has opened in the Kamchia Resort, with the ocean providing a stunning backdrop. Spanning a total area of 3,105 square meters, the classic design has been treated to a first-class technical infrastructure, with installation company Factor TC specifying a HARMAN’s JBL VRX/SRX sound reinforcement system—part of a complete HARMAN Professional deployment—as well as designing and installing the lighting.

Factor TC were recommended to the project and the design was overseen by Vesselin Todorov, president of the Sofia based company, along with Ing. Michael Michaelov from the Factor TC office in Varna.

Clusters of eight JBL VRX928LA (four each side) Constant Curvature loudspeakers and 16 SRX722 loudspeakers, underpinned by six ground-stacked SRX728S subwoofers, provide balanced arena coverage for a range of performances—from full-on rock concerts to spoken word—with an LED light and water fountain show also presented in front of the stage. Meanwhile, six JBL EON515XT active loudspeakers, serving as floor monitors, provide performers with their reference sound. All speakers are weatherized and water resistant to withstand the rigors of operating outside.

The passive elements of the system are powered by a combination of three Crown XTi 6002 and 10 XTi 4002 amplifiers. System management is under the command of a dbx DriveRack 260, which provides full bandpass and crossover configurations as well as independent output processing, augmented by a pair of dbx 166 compressor/gates, dbx 2231 dual 31-band graphic equalizer and Lexicon MX400 4-in/4-out reverb/FC processor.

The front-of-house sound engineer has been equipped with a Soundcraft GB8/32. This 32-channel desk was chosen for its versatility, since its dual-mode topology allows it to be used both for FOH and monitor duties.

Both the lighting and loudspeaker systems are assembled on a dismountable mobile aluminum structure and control is handled from a dedicated control room connected to the stage.

While the classic amphitheater has been designed from the ground up the remainder of the resort is undergoing complete refurbishment by owners, the government of Moscow. Project management was handled by PMC, ing. Ludmil Angelov was the construction company and Viktor Buzov the architect. SOC Kamchia are the main investors.

The result is a first-class construction, with the surrounding landscaping and planting complementing the natural environment of the facility.

Delicate Productions Holds Training Session For MLA Compact


Delicate Productions Inc.’s San Francisco office recently conducted an in-depth three-day training session for the Martin Audio MLA Compact loudspeaker system.

Attended by 12 top-tier Delicate touring and regional engineers along with notable independent engineers and facility owners interested in MLA technology, the session had a practical mission according to General Manager George Edwards.

“We currently own an inventory of MLA and MLA Compact enclosures,” Edwards explained, “and we feel that any product with this level of depth and sophistication requires not only our staff to be properly trained but also allows exposure to what Delicate and Martin Audio have to offer in sound reinforcement.

“So we put all of the attendees as close to MLA as they could possibly get with the person who knows the most about the technology, ‘Ferrit’ Rowe.”

Rowe, Technical Training Manager for MLA, headed the informative training, which started with basic audio and array studies before moving on to MLA Compact and VU-Net control software, system design, rigging and setup. Extensive one-on-one listening and Q&A sessions supplemented the sessions.

Asked about the results of the training, Edwards concluded, “It was incredibly helpful. Not just for our engineers, but for our guests as well. As the largest Martin Audio house in Northern California, it’s obviously in our and the product’s best interest to further educate anyone who wants to know more about MLA and MLA Compact.”

Jacksonville Jaguars Score a New HARMAN JBL Sound System at EverBank Field

The new sound reinforcement system at EverBank Field in Jacksonville, Florida features eight JBL VLA line arrays, with another four planned for installation later this year.

NORTHRIDGE, California – Since opening in 1995, EverBank Field has been the home of the National Football League’s Jacksonville Jaguars and host to NCAA Football’s Gator Bowl. However, over the course of 17 years time took its toll on the Jaguars’ den and recently the 84,000-seat stadium underwent significant renovations, including an upgrade of the sound system with HARMAN’s JBL VLA line arrays.

EverBank Field’s management company Spectacor Management Group (SMG) hired Christopher “Topper” Sowden, Principal Consultant of Sowden and Associates in Fort Worth, Texas, to design and oversee the installation of the new audio system. The system was installed by locally owned Florida Sound Engineering Company.

Faced with the challenge of delivering high output and even coverage throughout the stadium, Sowden and his team designed a distributed line array system where VLA loudspeakers are mounted to lighting structures behind the stands. These line arrays are aimed at low-grazing angles of incidence into the seating space from behind the spectators.

“Considering that EverBank Field is a large, open and relatively shallow oval, we agreed that a distributed line array approach would provide a noticeable enhancement to the fans’ audio experience in the bowl,” Sowden said.

“The facility contains eight lighting structures placed around the stadium,” Sowden added. “Working with Florida Sound Engineering and [JBL Professional Senior Application Engineer] Brad Ricks, we decided the JBL VLA Series loudspeakers would be the best choice for this installation for their frequency response and ability to deliver high-impact sound over large throw distances.”

Eight of the 12 originally designed arrays have been installed with the remaining four scheduled for completion later in 2013. Each of the four speaker clusters on the sides of the stadium includes three VLA Series VLA601-WRX loudspeakers and one VLA901-WRX loudspeaker, along with two PD Series PD5212/64-WRX loudspeakers and one PD5212/95-WRX loudspeaker. The four end zone clusters each feature three VLA Series VLA601-WRX loudspeakers, one VLA901-WRX loudspeaker, with one PD5212/64-WRX and one PD5212/95-WRX loudspeaker.

In this configuration, the VLA provides high energy and increased low and high frequency response, all the way to the front row of the stands, with even coverage to all seating areas.

“The arrays were developed using a road show rigging concept that allowed their installation using either a 150-foot crane or two chain motors,” Sowden noted. “Each cluster only took about an hour to mount!”

“Because the lighting structures are forward from the upper deck rear seating rows, we covered that area with 32 JBL AM7212/26-WRX high-power 2-way speakers on poles behind the last row of seats, which we chose because of their extremely wide horizontal angle of coverage,” Sowden pointed out. “We also installed 52 JBL AW295 speakers below the edge of the upper deck to cover areas of the lower deck that were shadowed from the main system.”

“The combination of speakers and deployment gave us the ideal combination of sonic attributes to achieve exactly the sound coverage and musical quality we needed,” Sowden said. “The team is happy, the owner is happy, and the patrons get their socks knocked off. It’s like sitting in your living room listening to a high-quality audio system, except you’re there with 84,000 of your close friends.”

ATK Audiotek and HARMAN’s JBL VERTEC® Line Arrays Prove Victorious at Super Bowl XLVII

NORTHRIDGE, California – Providing audio services for the Super Bowl for the 16th straight year, ATK Audiotek deployed its custom-designed, cart-based audio system for Super Bowl XLVII, held at the Superdome in New Orleans. Once again, ATK Audiotek equipped its carts with HARMAN’s JBL VERTEC® line array loudspeakers for the Halftime Show of the National Football League’s championship game. The carts were also used for the rendition of “America the Beautiful” featuring the Sandy Hook Elementary School Choir and Jennifer Hudson, as well as Alicia Keys’ performance of “The Star-Spangled Banner.”

CBS’ Super Bowl XLVII broadcast reached an average of 108.41 million viewers in the United States, while a record 164.1 million people in the U.S. watched all or part of the telecast for at least six minutes. Beyoncé starred in the Halftime Show, which included a reunion performance with Beyoncé and her former Destiny’s Child bandmates, Kelly Rowland and Michelle Williams. The Post-Game Show included the Lombardi Trophy presentation, awarded to this year’s NFL champion Baltimore Ravens.

For Super Bowl XLVII, ATK Audiotek deployed 16 of its custom-designed cart systems, which allow for easy setup between events, and quick transport of the JBL VERTEC loudspeakers on and off the field. Eight of the carts included five VERTEC VT4889 fullsize line array elements, while the other eight carts included four VT4889’s. Each cart was also equipped with two VT4880A fullsize arrayable subwoofers, while the four carts that split the 50-yard line for field foldback also each held two VRX932 Constant Curvature loudspeakers.

“We have relied on VERTEC line arrays in the Super Bowl for several years running and they have not let us down thanks to their reliable performance and high output,” said Kirk Powell, Engineer in Charge for ATK Audiotek. “In one of the world’s most widely-viewed televised events of the year, we need an easily-deployed, world-class loudspeaker system and that’s what we have with VERTEC.”

MHA Audio Installs MLA Compact In Lisner Auditorium

A fixture in Washington DC live entertainment since the Second World War, George Washington University’s Lisner Auditorium has hosted an eclectic mix of performers from Ingrid Bergman to Pink Floyd, along with leading world music artists, local opera and symphony companies and celebrated political dignitaries over the years.

The university recently decided to upgrade the venerable auditorium with special emphasis on the sound and lighting systems. MHA Audio, a successful local production company and integrator based in Hagerstown, MD, was tasked with installing the new audio system.

Discussing why he got involved with the project, MHA owner Mike Scarfe said, “We don’t normally do much installation work, but we have an outstanding relationship with Lisner and George Washington University based on doing live shows there for over 20 years, so this project made a lot of sense.

“It was also a perfect opportunity in terms of timing to bring Martin Audio’s new MLA Compact system into play and it all came together really well. The 1500-seat venue was the perfect size for the system. We put eight MLA Compacts per side with a center array of six DSX subs under the stage. The system was a natural choice because we’d had such a great experience with Martin Audio’s MLA touring system and this technology is definitely state-of-the-art.”

Discussing the University’s decision to modernize the sound and lighting systems, Executive Director of Lisner Auditorium and Partnership Development at GWU Maryann Lombardi explains, “We haven’t had a significant upgrade since the early forties and we needed to make the venue more competitive in terms of attracting high-profile talent.

“The environment for entertainment venues in the District of Columbia, Maryland and Virginia has changed dramatically in the last 20 years with more venues offering increasingly sophisticated capabilities. Our job is to become more competitive within that market. We’ve held a very prominent place in the past, but we really wanted to branch into other genres and better support our world artists.”

“In addition to a new sound and lighting package,” continues Lombardi, “the facility upgrade included a complete physical upgrade in terms of a new interior, seats, painting, carpet, stage floor, hanging points in the ceiling for lighting and sound, and a new heating and cooling system.”

Since the upgrade, Lisner has presented a series of popular and well-attended world music concerts by artists such as the Brazilian singer-songwriter Gilberto Gil and Acoustic Africa, as well as the sold-out debate between Fox’s Bill O’Reilly and the Daily Show’s Jon Stewart.

Asked about her impressions of the sound system since the MLA Compact system was installed, Lombardi enthuses, “I’m thrilled. It really has made an enormous difference in the sound quality. We’ve also gotten very good reactions from legacy clients such as the Air Force Band, Gilberto Gil, the Heritage Awards and artists using the equipment for the first time.

“We are now vetting performers and looking through their contract riders as we venture into new genres and it’s really cool to say we now have this sophisticated sound system in place that they can put to good use.”

Eric Annis, Production Manager and Technical Director for Lisner, is also enthusiastic about the new MLA Compact, “We think it’s fantastic and so do all the users who have come in since the installation.

“We’ve had several televised events in a row and maintaining the sightlines within the auditorium is wonderful,” adds Annis. “The shows have run the gamut from loud electrical music to a single mic bluegrass band, and the MLA Compact system has proved to be equally articulate and clear.”

About MLA™ (Multi-cellular Loudspeaker Array)
The result of many years of intensive R&D, MLA’s methodology replaces trial-and-error array design with intelligent numerical optimization of the array’s output based on a highly accurate acoustic model. The multi-cellular format has six individual cells in each enclosure, each with its own DSP and amplification.

With up to 24 enclosures, each MLA array has up to 144 cells — too great a number to optimize manually, or by ear. Instead, Martin Audio’s proprietary Display2™ system design software automatically calculates FIR DSP filters for each cell and a redundant-ring audio network (U-NET™) downloads the settings into each array enclosure. Martin Audio’s VU-NET™ software provides real-time control and monitoring of the system.

MLA delivers a frequency response and SPL consistency never before achievable; a very high system output (140dB peak, per cabinet @1m); Automatic optimization of the array, both physically (splay angles) and electronically (DSP); Computer control and monitoring of the entire system, and total control of sound system balance for engineers and sound technicians.

MLA is fully integrated, with Class D amplification, DSP and U-NET digital audio
network built into each enclosure. MLA complete systems are ready-to-use, with MLA, MLD and MLX enclosures, flying hardware, software, cabling and training all supplied. Everything needed is included. All ancillary items — from tablet PC and Merlin™ controller to network interconnects and mains distro — are also included in the complete system package. This ensures full compatibility worldwide, down to cabling and accessories.

Additional features include 90° x 7.5° dispersion; a compact size (1136mm wide x 372mm high x 675mm deep), one-box-fits-all (festivals to theaters) application range and a global voltage, power factor corrected power supply.

MLA’s compact size and very high output allows it to be shipped using smaller trucks, offering considerable savings and reduced carbon footprint. The system also includes the MLX powered, flyable subwoofer capable of an unprecedented measured peak output of 150dB @ 1m; MLD downfill cabinet, and Merlin 4-in/10-out system controller and network hub. Audio input is via analog, AES3 or U-NET.

By adopting these principles and system components MLA is optimized for every member of the audience — from a 2,000 capacity theater, to a 20,000-seat arena, to a 100,000-person festival site. It will deliver the engineer’s exact mix to every seat (up to over 150 meters) with precision, exceptional power and clarity.
