HARMAN’s JBL Professional CBT Column Loudspeakers Enable Firetron to Do More with Less at Guy K. Traylor Stadium

NORTHRIDGE, California – Home to the Lamar Consolidated Independent School District High School football team in Rosenberg, Texas, Guy K. Traylor Stadium is a 12,000-seat multipurpose venue. Seeking to upgrade its audio reinforcement system, the district called upon systems integration firm Firetron of Stafford, Texas, to install a unique new system highlighted by HARMAN’s JBL CBT Series column loudspeakers.

The previous system at Guy K. Traylor Stadium consisted of loudspeakers arranged at the end zones of the field—a setup that Richard Phillips, Sales Engineer for Firetron, saw as insufficient for the stadium’s needs. “I strive to bring the loudspeakers as close to the audience as possible to get maximum fidelity,” he said. “The stadium had an end zone system and it only lasted six years. As a general rule, I feel that distributed systems usually work better than end zone systems, so we developed a distributed concept utilizing CBT column loudspeakers.”

Firetron designed and installed a system featuring four JBL CBT 200LA-1 column loudspeakers on each long side of the stadium—four behind the home team stands and four behind the visiting team stands. The system is powered with Crown IT6000 amplifiers with BSS BLU-100 processing. “The wide coverage of the CBT’s enabled us to achieve high-impact sound and even dispersion with relatively few loudspeakers,” Phillips added. “The system is also broken into two discrete parts—one on the home team side and the other on the visiting team side—so each side can operate autonomously.”

At 6.6 feet tall with 32 drivers, the CBT 200LA-1 provides consistent pattern control over a wider bandwidth than is possible with shorter columns or fewer drivers. Vertical pattern coverage is adjustable to either 15 or 30 degrees to match the architectural characteristics of a wide variety of venues, and a variety of mounting heights. In addition, an innovative asymmetrical progressive-gradient coverage mode can be selected, directing more sound toward the far areas of the listening space to help reduce variation in SPL levels from front to back throughout the area.

“It’s the first time I’ve installed the CBT speakers and the project turned out great,” Phillips noted. “The school district is very happy with the quality of the sound and the system is very easy for them to operate.”

Overture Center Installs L-ACOUSTICS at Historic Capitol Theater

Complex’s oldest and second-largest venue now home to a KARA system

MADISON, Wisconsin — First opened in 1928, the Capitol Theater is the oldest and second largest venue in Madison, Wisconsin’s Overture Center for the Arts complex, which today encompasses seven performance facilities and four art galleries. Despite undergoing a major renovation project eight years ago that halved the historic vaudeville house’s capacity to approximately 1,100 seats, the Capitol’s sound reinforcement system hadn’t been updated for nearly two decades, prompting the recent installation of a new L-ACOUSTICS amplifier and loudspeaker package. more

Daktronics Redesigns Audio System at University of Wisconsin’s Camp Randall Stadium with HARMAN’s JBL VLA Line Arrays

MADISON, Wisconsin – In time for the football season, Daktronics recently redesigned the video board and audio system at the University of Wisconsin’s famed Camp Randall Stadium. Home to the Wisconsin Badgers football team, the stadium seats 80,321 people and is the 41st largest stadium in the world. To match the intensity of some of college football’s most dedicated fans, Daktronics selected HARMAN’s JBL VLA Series line array loudspeakers for the new audio system.

“We modeled different designs from many different manufacturers before deciding to use the VLA loudspeakers. No other system could deliver a confident outcome besides the VLA design,” according to David Sturzenbecher of Daktronics.

The new system consists of 18 JBL VLA301H loudspeakers, 14 JBL VLA 601H loudspeakers, three JBL PD743 loudspeakers, two JBL PD5212 loudspeakers, 12 AWC82 loudspeakers and 21 AW295 loudspeakers. Four line arrays cover west, south and east seating areas, with many fill speakers covering the north seats and upper seat fills.

“The design of the stadium presented many challenges including a very deep under-balcony area that was shadowed from the main display. This area required a completely separate submix in order to blend properly with the main system,” Sturzenbecher added.

With system design/commissioning assistance from Shay McElwain of the University of Wisconsin Athletics department, Draktonics successfully completed this massive overhaul of the stadium’s system.

“After some system optimization over the first two events, the system is currently operating extremely well and has received many positive reviews,” Sturzenbecher concluded.

DANLEY SOUND LABS LOUDSPEAKERS AND SUBS CONTRIBUTE TO TRUE STEREO IMAGING AT FIRST FREE CHURCH

ROCKFORD, ILLINOIS: First Free Church has been a cornerstone of spiritual life in Rockford, Illinois since 1884. Over the decades, First Free has occupied several buildings of ever-growing size and, since the advent of A/V technology, ever-growing technical sophistication. Its current sanctuary seats close to 1,800 congregants in an arc spanning nearly 180 degrees, with a balcony and under-balcony area that stretches from wall to wall. Tired of poor coverage from a faux-LCR system of mid-1990s vintage, First Free hired SVL Productions of nearby Cherry Valley, Illinois to build a new system that would provide nearly every seat with crisp stereo imaging. Of course, this would be no small feat to achieve. SVL Productions turned to Chicago-based Johnson AV Engineering to help design and commission the new system, which relies on the tight pattern control of Danley Sound Labs loudspeakers to meet – and then greatly exceed – the church’s expectations.

“Music is a vital component of First Free’s services,” said Aaron Johnson, president and principle engineer at Johnson AV Engineering. “The old system had three clusters to cover different wedges of the room’s wide arc, but despite the fact that they were set up as a Left-Center-Right system, none of the seats had any true imaging to speak of. The church wanted true imaging, where each instrument seems to emanate from the empty space between the loudspeakers, but that’s very hard to achieve in such a wide arc. You can’t simply place a couple of clusters on either side of the stage and expect even coverage and convincing imaging. The relative volume and time delay of each loudspeaker at the listener’s location have to be nearly equal to make the stereo effect work.”

The solution was to divide the room into three 60-degree wedges, each of which would receive its own stereo image. Although that’s easy to conceptualize, it’s very difficult to actually implement because almost all loudspeakers spill energy “off-axis.” That spillover would cross the dividing line between one wedge and the next and destroy the stereo imaging effect. “Danley’s tight pattern control made it the obvious choice for this application,” said Johnson. “No other loudspeaker manufacturer comes close to Danley’s razor-sharp pattern control, which extends even to lower frequencies.”

Because of their specific coverage patterns and the geometry of the room, Johnson specified a Danley SH-60 on top of a Danley SM-96 at each loudspeaker location for coverage of the main seating area. A total of six such clusters comprise the main system: three sets of left and right. Four monophonic Danley SH-Micros provide front fill for seats very near the stage. Partitions separate six under-balcony areas, four of which seat thirty to forty each and two of which seat only eight. For the larger partitions, a stereo pair of Danley SH-Micros deliver convincing stereo imaging, whereas a single Danley SH-Micro in each of the smaller partitions deliver a monophonic summed signal.

“I don’t know of another loudspeaker that can achieve the kind of pattern control that Danley has managed,” said Brent Hayes, president of SVL Productions. “Aaron and I walked the room during commissioning, and it was truly astounding to step just past the edge of one loudspeaker’s pattern. It fell off immediately. One more step and we were clearly into the pattern of the next loudspeaker. I remember seeing it on paper, but it’s a whole other thing to experience it.” Johnson agreed: “I love that Danley products always model exactly like they work, and they work exactly as you expect them to.”

But the miracles of great pattern control don’t stop with the loudspeakers at First Free Church. Johnson designed a directional subwoofer cluster comprised of three Danley TH-118s flown near the ceiling, just in front of the stage. By paying careful attention to each unit’s phase and signal delay, the bass volume on stage is a full 18 dB lower than it is in the seats, which is an obvious and significant difference. The dividing line is, in Johnson’s words, “like a curtain,” and even the first row of seats is fully immersed in bass. By keeping so much low-frequency energy off the stage, the sound quality captured on stage by open microphones is much better and far less likely to growl or feed back.

Processing support for the new system is extensive, as proper alignment required a separate processing channel for almost every individual loudspeaker and subwoofer. BiAmp Audia provides that fine-scale level of control. Because the Danley loudspeakers and subwoofers require only a single amplifier channel, the total number of amplifiers was kept to a minimum, but the sheer number of loudspeakers and subwoofers involved still amounted to an impressive 26 channels. Powersoft K-Series and Ottocanali-Series amplifiers provide that power. “The new system requires more power to the loudspeakers and subs than the old system did, but the efficiency of the Powersoft units allow us to draw less AC power!” said Hayes. “As a result, we didn’t have to call in an electrician. Moreover, their physical compactness left an entire rack from the previous installation wide open. In summary, we had more processing channels, more amplifier channels, and more loudspeaker power, but less current draw and less space consumed.”

New video projectors and screens, together with a new high-end Chauvet lekos and LED lights completed the installation.

Slovak National Theatre Upgrades to IC Live

Bratislava, Slovikia – November 2013… Completed in 1886, the Slovak National Theatre was designed by Viennese architects Ferdinand Fellner and Hermann Helmer. Since 1920, the ornate, 1,000-seat building has been the seat of the Slovak National Theatre opera and ballet ensembles. The hall has also hosted performances by some of the world’s top opera and ballet talents.

Its acoustics, however, have come under more scrutiny. The room’s very short reverberation time, while acceptable for opera, doesn’t suit orchestral performances. Its narrow stage faces a long auditorium where the rear seats are 75 ft (22 m) away. Uneven sound coverage confronted its numerous balconies.

A subtle sound reinforcement system, effectively invisible to the audience, was needed, and the theater approached MediaTech, Bratislava’s largest pro audio company.

EASE analysis led to them recommending the IC Live digitally steerable system by Renkus-Heinz. Its clear, uncolored musical sound, the ability to steer multiple sound beams into specific areas of the audience offered precisely the solution that was needed. And its slim, low profile design — complete with a custom paint finish – complemented the theatre’s décor perfectly.

The system includes extra reverb for orchestral shows via a TC Electronics M6000, with a Yamaha PM5D console linked directly to the IC Live system via CobraNet. “The audience had to be unaware of sound reinforcement,” says MediaTech’s project manager Miroslav Paciga. “IC Live allowed us to achieve that subtle effect while being visually unnoticeable.”

Sound Image Tops Off Brad Paisley’s Tour With HARMAN’s JBL VTX Line Arrays and Crown I-Tech HD Amplifiers

NORTHRIDGE, California – Country music star Brad Paisley is currently in the final leg of his 2013 “Beat This Summer Tour” throughout the United States and Canada. To support Paisley’s exceptional voice and talents, Sound Image of Escondido, California, is providing HARMAN’s JBL VTX line arrays and Crown I-Tech HD amplifiers.

A total of 44 VTX V25 fullsize line array elements comprise the system on Paisley’s tour, along with 16 VTX S28 subwoofers, all powered by 40 Crown I-Tech 12000 HD amplifiers. “When I first heard the VTX system, I was shockingly impressed. I was amazed by the sound quality when we first fired it up,” according to Greg Hancock, Audio Crew Chief for the tour.

“There were specific sounds that Brad was looking for because he plays in a distinctive style. We were able to accommodate that, because with its high-frequency range, the VTX offers a lot more detail than our previous systems,” said Brendan Hines, FOH Systems Engineer.

Sound quality is not the only area where VTX exceeds expectations. It also enables extremely quick setup times, as VTX’s patented S.A.F.E. suspension system is streamlined for speed and efficiency with improved hardware for faster setup with fewer pinning operations and greater security.

“The flexibility and ease with which the VTX is set up benefits us in terms of completing the necessary system configurations to control feedback,” Hines added. “Having that much control over the feedback of those PA’s makes it much easier for tuning.”

The state-of-the-art performance of the VTX PA’s is further enhanced by the Crown I- Tech HD amplifiers, the pinnacle of advanced professional touring amplifier technology.

“The Crown I-Tech HD’s are a huge improvement, their reliability is outstanding, the sound quality is phenomenal, and the flexibility it gives you as a systems engineer is awesome,” said Hines. “We’ve taken another step in the right direction,” said Kevin Freeman, Production Manager.

HARMAN’s JBL and Crown Provide Sound for National Network of Cinemas Project In Mongolia

MONGOLIA — Most audio/video projects involve a single location and anything from a conference room to a domed stadium. That’s a major endeavor by anyone’s standards – but a project that involves equipping an entire country with a network of cinemas? That’s exactly what the Mongolia Ministry of Culture, Sport and Tourism (MCST) is currently undertaking in conjunction with systems integrator Cinema of Sound LLC and Kinoton Korea, Inc.

In their effort to provide professional high-quality cinemas to Mongolian citizens, Cinema of Sound and Kinoton are building Standard Cinema Point theaters in Mongolia’s aimags (first-level administrative subdivisions), villages and city districts. Twenty installations have been completed to date, spanning across the country’s nearly 604,000 square miles. Audio for all the installations is provided by HARMAN’s JBL JRX125 dual-15-inch loudspeakers and Crown DSi 2000 amplifiers, which are designed specifically for cinema applications.

“Mongolia is a country that has vast areas of scattered settlements and sparse population, so sparse that our country’s most remote citizens watch movies only on television, as there are no theaters,” said Jigjidsuren Khurelbaatar, CEO of Cinema of Sound LLC. “Thanks to our Standard Cinema Point project, which is part of the MCST’s efforts to bring a richer cultural environment to Mongolians, people throughout Mongolia will be able to enjoy a true cinema experience with high-quality sound and projection.”

Cinema of Sound LLC standardized on the JBL JRX125 loudspeakers and Crown DSi 2000 amplifiers for the Standard Cinema Point installations to achieve consistent sound, performance and reliability in every venue. “By standardizing the equipment we’re using, we know we can depend on a high level of audio quality and dependable day-to-day operation no matter where the theaters are located,” Chris Bae, Managing Director of Kinoton Korea, Inc.

The JRX125 incorporates features including dual 15-inch woofers with large 2.5-inch (64mm) edgewound ribbon voice coils, titanium-diaphragm compression high-frequency drivers and high-voltage crossover components to ensure exceptional performance under the most demanding conditions of day-to-day use. Crown’s DSi Series amplifiers are specifically designed to meet the needs of cinema applications and feature onboard digital signal processing including crossovers, EQ filters, delay and output limiting to deliver exceptional sound quality.

Cinema of Sound and Kinoton Korea are contracted to build 50 more Standard Cinema Point theaters in the remainder of 2013, bringing the total of theaters in Mongolia to 70. Theaters are currently installed in capital city Ulaanbaatar and in locations throughout the country.
