**** Photo: First FWB Church’s sanctuary ****

Wilson, NC – February 2013… First FWB Church, a Free Will Baptist Church located in North Carolina’s Coastal Plain region, recently re-opened its sanctuary after experiencing extensive damage as a result of a lightning strike that set the sanctuary ablaze. The fire and subsequent water damage (to extinguish the fire) forced church management to make major repairs to the space, including the installation of a new audiovisual setup—with loudspeaker systems drawn from the TrueLine and WaveSeries catalogs of Greensboro, NC-based WorxAudio Technologies. more

HARMAN’s JBL Loudspeakers and Crown Amplifiers Team Up to Provide Slam-Dunk Sound for Indiana Hoosiers’ Assembly Hall

NORTHRIDGE, California — Indiana University’s Assembly Hall, a 17,000-seat indoor arena is the home to the Indiana Hoosiers—one of the most storied teams in college basketball. The arena, which opened in 1971, was recently retrofitted with a new audio system featuring HARMAN’s JBL loudspeakers and Crown amplifiers. Pensacola, Florida-based All Pro Sound in conjunction with Sweetwater, Inc. of Ft Wayne, IN., handled the installation in coordination with New York-based Acoustical Design and consulting firm SIA Acoustics.

“Before we were called in, Assembly Hall was still using its original sound system from 1971. The arena had a lot of existing acoustical treatment but the sound quality in the lower frequencies was unbalanced and made it difficult for the crowd to hear speech announcements clearly. Needless to say, we had to bring the system up to today’s standards for performance, coverage and intelligibility,” explained Sam Berkow, Principal at SIA Acoustics.

As an older facility, Assembly Hall’s unique architecture caused some challenges in the installation process. The logistical difficulties of mounting the speakers to cover the arena’s unusual steeply raked seating proved to be difficult. “Any big arena like this is going to present some acoustical issues, but Assembly Hall is unique in that most of the seating is on two very steep sides of the court and go up high, and there are also balconies that are even higher,” added John Fuqua, Vice President, All Pro Sound.

“Because of the seating layout, we had to fly the speakers at 80 feet above the floor. We installed a mix of JBL VERTEC® VT4888DP midsize powered line array elements, PD5322/95 full-range speakers and ASB6128 subwoofers specifically to provide the best coverage and performance to all the seating areas,” stated Fuqua.

The PD5322/95 loudspeakers and ASB6128 subs are powered by eight Crown Macro-Tech i Series MA9000i, six MA5000i and 10 CTs 1200 amplifiers. Five BSS BLU-160 digital signal processors are also part of the system.

For the main arrays All Pro Sound installed six hangs of nine VT4888DP line array elements each, spaced around the arena. The 10 PD5322/95 speakers are used for upper balcony fill and are flown from the existing catwalk system. The ASB6128 subwoofers are hung in four arrays of four boxes each, placed near the outer main arrays.

“Sam Berkow and the SIA Acoustics design team chose this combination of HARMAN equipment because the JBL speakers are the right match in size and coverage capability, especially considering the odd vertical layout of the seats at the sides, and the electronics complement the speakers perfectly to achieve the highest level of performance for the venue,” concluded Fuqua.

“For this system, the job was contracted, the equipment procured and the installation completed in just 19 days from the receipt of the notice to proceed. We coordinated with HARMAN representatives, All Pro Sound, retailer Sweetwater and the Indiana University staff to streamline the process and facilitate this quick turnaround. It was an impressive amount of work to be completed and be up and running within such a tight schedule,” added Berkow. “We are extremely happy with the results.”

CAPITAL SOUND HIRE AND WIGMAN FIRST IN UK WITH NEXO STM SERIES

London-based Capital Sound Hire has become the first UK company to take delivery of a NEXO STM Series system, and Wigwam Acoustics has confirmed its purchase of a STM modular line array system, after two years of involvement in its development by both companies.

The initial STM touring range incorporates three elements; the M46 Main cabinet, B112 Bass cabinet and S118 Sub-bass cabinet, which allow users to build systems for audiences from 200 to 100,000. “With profit margins being squeezed, it’s crucial for the success of rental companies to get the maximum flexibility from their inventories,” continues Capital’s Paul Timmins. “Prep costs money, and this system only requires configuration between projects, with no rebuilds necessary.”

The scalability of STM held great appeal for Capital, whose projects range from 10 people at small corporate events to stadium and outdoor shows for 60,000 plus. “What has become evident is that most current loudspeaker systems require you to stock up to four sizes of line array boxes to cover the variation in room sizes,” says Timmins. “Often, during the winter months, an entire inventory of large format loudspeakers can sit idle while there is a shortage of small and mid-sized cabinets. The concept of STM is amazing, with true multi-use options for all components including the amplifier racks. System designs can take into consideration not only room limitations but also musical content. It’s a fantastic addition to the tool box.”

Capital, which will ultimately own a 48-box system an inventory of 48x M46 Mains, 48x B112 Bass and 48x S118 Subs, is initially planning to introduce the components on small-scale events. This will ramp up during summer 2013 to larger projects that will allow engineers to get to grips with its full capabilities. “NEXO has been a great company to work with,” concludes Timmins of the STM project. “They have a fantastic R&D team and they also know where all the best restaurants are!”

In STM terminology, Wigwam’s package is 48 sets: 48 x M46 main cabinets, 48 x B112 bass cabinets and 48 x S118 sub bass units. The system specification is identical to that ordered by Capital Sound. The main criteria for the new system, according to Wigwam’s Chris Hill, was, “will it sound good, will it be flexible, and quick to rig? NEXO engineers really listened; STM is scalable, and we can use it for many different applications instead of it just being able to do certain types of work. We’re hopeful that this will give us maximum utilization of our stock.”

Williams Arena’s Sound Is on the Rebound With HARMAN’s JBL Loudspeakers

NORTHRIDGE, California – It’s called “The Barn,” officially known as the Williams Arena, home of the University of Minnesota’s Golden Gophers men’s and women’s basketball teams. The Barn’s 14,625-capacity main arena has been renovated with an all-new sound system that includes more than 100 HARMAN’s JBL loudspeakers. Parsons Electric of Minneapolis, Minnesota was the systems integrator for the project. Parsons collaborated with Richmond, Virginia-based audio/video consulting and architectural services firm Anthony James Partners.

According to Tim Habedank, System Specialist for Parsons Electric, Williams Arena is a large, reverberant space, making it a challenge from a system design standpoint. “We had a reverberation time of about seven seconds,” Habedank said.

“The shape of Williams lent itself to a line array system because the hanging points were far enough away from the seating that we needed speakers that would cover a large area,” Habedank noted. “Williams has three seating levels, so we were able to direct the boxes to the different levels as needed.”

Parsons Electric installed eight line arrays, each comprised of six JBL VRX932LA-1 Constant Curvature loudspeakers, along with two additional arrays of four VRX932LA-1 loudspeakers each for court coverage. The system also features four subwoofer clusters, each containing three JBL ASB6128 subs, while 20 Control 30 loudspeakers are installed for upper balcony fill with 48 Control 29AV loudspeakers for lower balcony fill.

In addition, Parsons Electronic separated the VRX system into three zones—one for each level—so each zone can be controlled discretely with a touchpanel. “Williams is a multi-purpose arena, so for events that don’t require the full system, the top two levels of speakers can be turned off if only the lower level speakers are required,” Habedank said. “Or the top level can be turned off if only the lower and middle levels need to be reached. The system is easily configurable depending on the requirements of each event.”

“The VRX system really packs a punch and covers Williams Arena very well,” Habedank added. “We did some level shading on the system to ensure that every seat in the arena is separated by less than a few dB. We have really nice, even coverage with the VRX line arrays.”

Yamaha Commercial Audio Provides Sound System for Concert Celebrating Company’s 125th Anniversary

BUENA PARK, Calif.—Yamaha Commercial Audio Systems, Inc. (YCAS) played a major role in parent company’s 125th anniversary celebration, providing the sound system used at a concert held at the Disney’s Hyperion Theatre during the NAMM Show in Anaheim. YCAS managed all live audio production equipment requirements including the design and implementation of a large-scale Dante network from inputs to speakers and were on hand for assistance to guest artist engineers.

The concert, which featured performances by Amy Grant; Chaka Khan; Dave Grusin; Earth, Wind & Fire; David Foster; Dave Koz; Michael McDonald; Sarah McLachlan; Toto; Lucy Schwartz; new artist LEOGUN; the USC Marching Band; and house band, under the musical direction of Nathan East.

Three Yamaha CL5 digital consoles were used at front of house (one for the orchestra, one for the house band, and one for guest bands) for a total of 150 inputs, two CL5s were used at monitors, two DME64N digital mix engines were used for Dante Network Bridging and FOH speaker system processing, NXAMP4x4s for amplification with NX-DT104 Dante cards, NEXO RS18 and S118 subwoofers, NEXO PS10 speakers for front fill, NEXO 45N-12 stage monitors, LS600 and DXS15 subwoofers for drum mix subs, and, for flown for the first time in the U.S., the new NEXO STM line array used as FOH Mains.

“The new CL5 console is amazing,” states front of house engineer Bryan Lenox, who mixed many of the guest artists as well as the house band. “The three CL5s were linked together and talking to one another during a very complex show. We had a multitude of artists, background singers, multiple pianos, horns, percussionists, a multi-track recording truck, and a live broadcast stream of audio and video. The console is very user friendly and quick to get around; the flexibility, touch screen, and color-coding groups of faders are very helpful especially when having to make quick moves. The console routing is great, and although you can do just about anything with the routing, the layout can even be customized by the engineer.” Lenox said the Neve and Pultec plug-ins sounded great on kick, snare, bass, and vocals. “The new NEXO STM rig sounded unbelievable and very rich sounding while retaining detail, clarity, and punch. It was very easy to get a great sound with the combination of the consoles and the STM.”

The night’s crescendo, however, was Sir Elton John who ended the concert with an amazing five-song set. A historical evening for Yamaha Pianos as John played a Disklavier reproducing piano onstage, accompanied by a 60-piece orchestra, as his actual piano keystrokes were faithfully played, note for note, in real time (via MIDI data) on remote Disklavier pianos all over the world. He and the orchestra were visible on adjacent monitors in perfect sync with the remote piano performance, and even fans from around the world without a Disklavier were able to witness the event via a live streaming feed.

“I enjoyed using the CL, in fact, when we have solo shows with Elton similar to the Yamaha event, it will be my desk of choice,” states Matt Herr, front of house engineer for Elton John. “I’m a fan of Yamaha desks and have been for many years. The product reliability and global service is second to none.” Herr has been using a PM5K when the band performs with John. “The CL is very user friendly and sounded really good in my opinion. The Neve inserts sounded fantastic; I used one of the compressors on Elton’s vocal. Normally, I use an outboard compressor, but this one worked quite well. As far as the NEXO STM line array, it sounded nice and smooth, and I’d like to get my hands on it with the band and really drive it to see what it can do. It seems like it would be a good large line array as opposed to some of the smaller ones out there.”

NORTHRIDGE, California – HARMAN’s JBL loudspeakers were at the heart of Sunday’s 55th Annual GRAMMY® Awards, with JBL VTX line arrays comprising the live sound reinforcement system at the STAPLES Center and an LSR6300 Series 5.1 surround sound studio monitor system used in the Television Committee Room.

The annual GRAMMY Awards telecast, known as Music’s Biggest Night®, is presented by The Recording Academy® to honor outstanding achievements in the production and performance of recorded music. The GRAMMY Awards were broadcast live in HDTV and 5.1 surround sound on the CBS Television Network. More than 28.1 million people watched this year’s Awards telecast, the second-largest audience for the GRAMMY Awards since 1993.

This year’s Awards were hosted by LL Cool J and featured performances by The Black Keys, Mumford & Sons, Rihanna, Taylor Swift, among others. The rock band fun. earned Best New Artist and Song of the Year for “We Are Young,” while Gotye won Record of the Year for “Somebody That I Used to Know,” along with two other GRAMMY Awards. Mumford & Sons earned Album of the Year for Babel.

ATK Audiotek supplied the live sound reinforcement system for the Awards, which featured left-right columns of 12 VTX V25 fullsize line array elements per side for the main PA, with additional left-right columns of 12 V25 per side for out fill, along with a center cluster of 18 VTX S28 arrayable subwoofers in cardioid mode (two arrays of nine S28 subs each), for a total of 66 VTX loudspeakers. Six VRX932 Constant Curvature loudspeakers served as front fill, with left-right rear delay arrays of eight VERTEC® VT4889 fullsize line array elements each. Powering the loudspeakers were 16 Crown Audio VRack 2000 and four VRack 4×3500 and the entire system was configured using JBL HiQnet Performance Manager™ software. The house sound system at the STAPLES Center, featuring VERTEC VT4888ADP-DA powered line array elements, was used to supplement the live sound system with five enclosures from the center end array used for rear upper deck and VIP box coverage.

“This year we used the newest evolution of the JBL line array,” said Jeff Peterson of ATK Audiotek. “The V25 had a very clear and smooth high end which didn’t distract our attention. All of the low-end power we’re accustomed to with the VT4889’s was there and then some. The S28 sub is so efficient we never came close to using all of the available power. Tying it all together, Performance Manager gave me all the control and monitoring I needed.”

In the Television Committee Room, Michael Abbott, Audio Director for the GRAMMY Awards, along with Recording Academy executives, relied on JBL LSR6300 Series studio monitors to listen to the mix of the show in real time. “We were able to take advantage of the LSR6300 Series’ RMC Room Mode Correction technology to ensure that we were accurately hearing the subtleties in the mix,” Abbott said. “As has been the case for several years, the LSR6300 Series performed flawlessly at the GRAMMY Awards.”

HARMAN’s JBL Professional Loudspeakers Fill Out the Sound System at Penn State’s Beaver Stadium

NORTHRIDGE, California – Beaver Stadium, home to Penn State University’s Nittany Lions football team, is one of the largest in the country with a capacity of almost 107,000. In fact, it is the second-largest stadium in the Western Hemisphere. The stadium has expanded six times in its history and recently, systems contractor Clair Brothers upgraded Beaver Stadium’s sound system with the installation of more than 140 HARMAN’s JBL loudspeakers to improve its performance in a number of coverage areas.

“We had already replaced the main PA system in 2007 with a comparatively small JBL VLA601 and VLA301 line array system, but work still needed to be done to address areas in the North and South end zones of the stadium where the sound from the main PA is blocked or where we determined that additional coverage was needed,” said Jim Devenney, Sr. Systems Designer and Project Manager at Clair Brothers. “The balconies are large and present significant acoustical barriers. There were already speakers in place in these areas but they had been there for a while and needed to be upgraded.”

“In the South end zone there are three separate areas, the main PA does not cover since the PA shoots over the top of the entire area. The tight down angle from the top of the scoreboard makes it impossible for the main PA to adequately reach those areas.”

“The lower level is used mostly for student seating, we mounted 16 JBL All Weather Series AW295 all-weather speakers on the face of the balcony to cover these seats between the balcony and the field. In addition there are 36 of JBL’s All Weather Series AWC82 outdoor speakers positioned in two alternating rows of 18, with 18 pointed straight down and another 18 placed in between them and aimed back away from the field to cover the area under the balcony.”

“The Club Level is the next level up and here the balcony directly blocks the sound from the main PA. To remedy this, 14 AW295 speakers face toward the field and 52 AWC82 speakers are placed facing down. There’s a seating area under the scoreboard that also needed attention. We added 24 JBL Control 25AV indoor/outdoor speakers to deliver sound to the people sitting under the scoreboard.”

“The top of the lower level seating in the North end zone is also shaded from the main system by an overhanging balcony. We installed 10 AWC129 speakers here.”

When it comes to installation challenges Clair Brothers has seen it all, yet the Beaver Stadium upgrade threw the proverbial fly in the ointment for Devenney and crew. “Putting up the speakers was the easy part,” Devenney said. “Our installers loved the speakers as they were well-designed and easy to mount. However, we had to install them during the Penn State football season so we had to put up and take down the scaffolding after every game. The schedule was also so tight that we had the speakers flown from the plant as soon as they were manufactured! We still were able to complete the installation in four weeks. The stadium’s operations staff was very helpful with logistics, ensuring the system installation would stay on schedule.”

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.”
