Firehouse Productions Does Its Part With HARMAN’s JBL VTX Series Line Arrays and Crown Amplifiers for 12-12-12 The Concert for Sandy Relief

Firehouse Productions provided a total of 82 VTX line array loudspeakers for 12-12-12 The Concert for Sandy Relief at Madison Square Garden.

NEW YORK, New York — It was the most significant music event of the year: 12-12-12 The Concert for Sandy Relief, held at Madison Square Garden on December 12, 2012 to benefit the Robin Hood Relief Fund. The concert featured many of the biggest stars in the music industry including Sir Paul McCartney, Eric Clapton, Bruce Springsteen & the E Street Band, Roger Waters, Bon Jovi, Billy Joel, Alicia Keys, Kanye West, The Rolling Stones and many others. The sound for the event was equally stellar, thanks to HARMAN’s JBL VTX Series line arrays powered by Crown I-Tech HD Series programmable amplifiers.

To fill the 18,000-seat Garden, sound reinforcement contractor Firehouse Productions of Red Hook, New York deployed a large JBL VTX Series rig including two main left and right PA columns of 18 V25 full-size line array elements, complemented by two outfill arrays of 12 V25’s, with four VERTEC® VT4886 subcompact line arrays serving as under-hangs. Eighteen S28 and four G28 dual 18-inch cardioid arrayable subwoofers were ground-stacked to complete the VTX installation. All the speakers were driven by Crown IT12000HD power amplifiers with system control provided by JBL HiQnet Performance Manager™ software.

“We had to be completely at the top of our game for this one—although we’ve done many high-profile events, it’s not every day we get to do the sound reinforcement for a concert that’s broadcast around the world to more than a billion people,” said Mark Dittmar, Lead Design and Integration Engineer of Firehouse Productions. “We’d been using JBL VERTEC® line arrays for more than a decade and that product has been spectacular in terms of sound quality, relative light weight and versatile rigging options. That said, with JBL VTX the sound quality we can achieve has gone up a whole other level. VTX sets new standards in clarity and impact, and delivers a consistently smooth and natural response.”

“In fact, the low end from the VTX V25 main arrays is significantly increased—to the point where we’re not flying subs with the system. We stacked the S28 and G28 subs on the ground to give the system additional low-frequency impact but we did not need to fly subs as part of the main array columns as we have in the past.”

“We have used Crown amplifiers ever since we started Firehouse,” Dittmar noted. “The IT12000HD offers us power and flexibility that we can’t get with other products. With the introduction of the VTX line arrays and the newest V5 DSP presets for VTX, the sound quality is spectacular.”

For Dittmar, deploying JBL HiQnet Performance Manager software worked out to be a major benefit. “The JBL HiQnet Performance Manager software makes setting up and controlling the system a lot easier and more accurate. In fact, the 12-12-12 show was only the second time we had ever used Performance Manager – the first being the Z100 Jingle Ball 2012 at the Garden the week before! I’m happy to say it worked perfectly for us,” added Dittmar.

“12-12-12 was one of the most challenging projects we’ve ever done,” Dittmar concluded. “Funny enough, though, the PA turned out to be one of the simplest aspects of the project. Using all JBL line arrays all around the Garden made a huge difference in getting the sound to be consistent throughout the arena, and consistently excellent.”

Iconyx Delivers for the Daily Planet

Overcoming a Towering Acoustical Challenge at  North Carolina’s Museum of Natural Science

Raleigh, NC, December 2012.… Already one of the largest facilities of its kind, Raleigh’s Museum of Natural Sciences recently completed work on an impressive new addition: the 80,000 square foot Nature Research Center (NRC). Featuring state-of-the-art labs, research opportunities, and numerous interactive exhibits, the crown jewel of the new NRC wing is surely the SECU Daily Planet, an intensely immersive, three-story multimedia space that engages visitors with a flurry of sight and sound, while offering a powerful message about the wonders of science in our daily lives.

Designed to facilitate both pre-recorded and live content, the Daily Planet’s massive, three-story visual display runs continually-projecting a variety of poetic and informational content to excite the senses. A small stage at ground level also allows for occasional live presentations. The entire Daily Planet exhibit resides in a massive, dome-shaped room with two balcony levels extending seven feet into its center. The three-level design allows visitors to choose from three unique vantage points as they take in any of up to 50 powerful presentations that run throughout the day.

With its unique ellipsoidal shape and vantage points from a main level and two balconies, delivering impactful and immersive audio consistently to all three levels presented numerous obstacles. Rising to the challenge were AV integrators Electrosonic, in partnership with Milford, CT-based SH Acoustics, who created a system centered around Renkus-Heinz’s Iconyx series steerable column arrays.

“Unlike similar spaces – for example, an Omnimax Theater – the Daily Planet needed to accommodate a variety of different formats, including lectures and live performances,” explained Steve Haas, Founder and President of SH Acoustics. “The room’s unique design and its numerous reflective elements created some unique challenges right from the beginning. We knew we couldn’t simply apply tons of sound-absorptive materials because deadening the room too much wouldn’t work well for lectures.”

As Haas observes, the Iconyx steerable beam technology would allow them to more effectively direct the output and avoid unwanted reflections, while at the same time addressing the unique acoustic requirements at all three levels.

The complete Renkus-Heinz loudspeaker complement includes eight Iconyx IC8-R-II steerable arrays for mains, augmented by ten SG61-2R powered two-way systems for surround, with three PN112SUB 12-inch powered subwoofers providing powerful low-end reinforcement.”We decided very early that we wanted to create three different audio experiences on each of the three levels,” explained Haas. “In addition, each level needed to be surround sound, and most importantly, needed to ensure minimal interaction between adjacent levels and the rest of the room. This is where the Iconyx system was a no-brainer.”

Haas elaborates, “The first and second levels each include left, center, and right, as well as four surrounds. On the third level the dome is much tighter, so we opted for just left and right with two surrounds. For low frequencies, we placed all three subwoofers on the second level. There simply wasn’t enough room for discreet subs on each level, so we configured each one as the point sources for the adjacent levels, and delayed the LF signal appropriately from the first level, second level and third level. It actually worked quite well.”

Once installed, Haas and his team were able to take full advantage of the Iconyx system’s beam steering capabilities to dial in the perfect output at the ground floor and both balconies.

“We needed to make sure that we had a very tight pattern-at least vertically-so that the experiences at each level did not interact with each other in any appreciable way.” Haas explains. “We were able to get the second and third levels sounding fantastic with little difficulty. The first level was a bit more challenging, but the Iconyx beam steering, combined, with the careful addition of diffusion materials, made all the difference.”

After the system was configured, Haas worked with the museum production staff to save a number of unique output presets that could be easily retrieved to accommodate different program types.

“There are several different modes including a presentation mode and a media mode,” says Haas. “We even gave the producers the opportunity to have a secondary beam from some of the upper arrays-like from the second level down to the first level-in case they wanted a spot effect or some other secondary sound source.”

In the end the results speak for themselves. The new NRC wing and Daily Planet exhibits are big hits with museum attendees and management alike. And for Haas, this is yet another seemingly impossible acoustic challenge conquered through a synergy of great technology, real-world know how and savvy partnerships.

Haas sums it up: “We like challenges, and we have a very long history of working successfully with Electrosonic on unique projects like this. We absolutely love coming up with unique solutions, and as a technology partner, Renkus-Heinz has always been there with fantastic tools. They’re just great to work with.”

Iconyx Delivers a Top-Down Approach for Two Aquatic Centers

chilliwack renkus heinzChilliwack, BC, Canada – For an audio professional, creating a sound system for a large aquatic center is not a simple task. The combination of high walls, corrugated metal roofs, and an abundance of concrete, glass, and water makes for an acoustical environment that is far from pretty, even before it’s packed with noisy revelers.

Rising to the challenge was Chilliwack-based Go Audio, the company behind the audio installations at both Cheam Leisure Centre and cross-town neighbor Chilliwack Landing Leisure Centre. Both projects employed a very novel design approach featuring the Renkus-Heinz Iconyx digitally steered array.

Unlike most applications where the steered array is used as a vertical column line array, the approach at the aquatic centers involved suspending the Iconyx from the roof overhead, and steering the beams to focus the sound away from the walls and other highly reflective surfaces.

The Cheam project came first. Go Audio’s Mike Evans called Fred Gilpin of Renkus-Heinz distributor Contact Distribution, and asked him to have a look at the project. “We’ve worked with Fred on other projects, including a church in Vancouver that had very challenging acoustics,” says Evans. “We installed Iconyx IC16 and IC8 there and it worked great, so we were confident that Iconyx would be the best choice.”

The Cheam system includes six IC7-WR powered column arrays, with a Rane processor handling system DSP. “Because of the Iconyx’s very narrow vertical dispersion, we positioned four IC7’s horizontally over the outer walkway, aimed slightly inward,” Evans explains. “We were able to keep the sound completely off the walls and cover just the walkway and a bit of the pool. Two more IC7’s suspended at 45 degrees cover the water with minimal overlap. The coverage is seamless wherever you are, with no need for delays.”

Based on the success of the Cheam project, Go Audio was called back to revamp the audio system at Chilliwack Landing. “That project was a bit more challenging,” says Evans. “The space is configured a bit differently, and there was some ductwork we had to work around as well. We ended up using a total of ten Iconyx boxes to cover everything.” With an existing rack of Crown CTi-series amplifiers and wiring already in place, the decision was made to go with unpowered ICX7-WR units.

Evans reports that management and patrons alike at both venues have been very pleased with the results. “The primary objective was spoken word intelligibility for safety announcements and such,” he says. “But the Iconyx has been great for background music as well. Typically in this sort of environment, it’s just too reverberant to run background music at the levels necessary to overcome the ambient noise. But with the Iconyx, the music is exceptionally articulate, even at lower levels.”

Evans concludes, “I was amazed the first time I stepped out of an Iconyx steered beam and immediately recognized how useful this speaker system would be! It’s very gratifying hearing the clarity Iconyx delivers in these challenging environments.”

ENTASYS Delivers Low Profile, Big Sound for Legendary San Francisco Theater

communityproSan Francisco, CA – December 2012….. The Lincoln Highway was the first automobile road across the United States, stretching from New York’s Times Square to San Francisco. Marking the road’s western end, high on a hill overlooking the Pacific and the Golden Gate Bridge, is the California Palace of the Legion of Honor. The building, a magnificent three-quarter-scale reproduction of Paris’ Palais de la Légion d’Honneur, is home to a wide and varied collection of ancient and European art spanning more than 6,000 years.

The Palace is also home to the Florence Gould Theater, an ornate 333-seat jewel box auditorium designed by museum architect George Applegarth. Opened in 1924 as the Little Theater, the venue hosts a regular calendar of concerts, lectures and theater performances.

The theater’s massive columns, rounded walls, and domed ceilings create a breathtaking environment, as well as some legendary challenging acoustics. “The room has no acoustic treatment whatsoever, and an abundance of hard surfaces,” offers Joe Orlando of Atwater, CA-based Commercial Media Systems. “It’s highly reverberant, and spoken word intelligibility is pretty much non-existent.” Commercial Media created the system design and assisted the Museum’s production department with the installation.

“The room works great if you’re onstage and you have a good, theatrical speaking voice,” observes John Anaya, Production Manager for the Fine Arts Museums of San Francisco. “But for amplified sound, the room has some very problematic reflections. In fact, we found that the best seats in the house for sound were in the very back of the theater, while the front rows had terrible sound.”

Over the years, a succession of audio systems has failed to make a significant impact on the problem, until CMS recommended an upgrade to four Community ENTASYS high-performance column line arrays. A pair of ENTASYS full-range columns are mounted on either side of the proscenium, powered by the museum’s existing Hafler amps.

“Due to the room’s architecture we had to mount the speakers much higher than what would have been the optimal height,” Orlando explains. “But the ENTASYS columns enabled us to angle the arrays and focus the sound downward to the seating area, and off the walls and domed ceiling. ENTASYS is really the only system that would have worked in that space.”

“Of course, we were not going to put anything in here that affected the aesthetics of the room,” adds Anaya. “The ENTASYS speakers blend into the space perfectly; they match the walls so well, we find we have to point out to people where the speakers are.”

Anaya sums it up: “It has been like night and day. The clarity in the room is phenomenal.”

Community ENTASYS Provides the Audio Solution for the Heilig Hart Church

Boom, Belgium – December 2012….. The Heilig Hart (Sacred Heart) church in Boom, just South of Antwerp in Belgium, has recently had a new Community audio system installed by communication and integration specialist, Zelzate-based Tevean nv.

With capacity for up to 700 people and contemporary architecture, the large open space required good pattern control loudspeakers to avoid the reflective surfaces in the highly reverberant environment. Community ENTASYS three-way, full-range, column-line-array systems were chosen for their ideal wide horizontal and extremely narrow vertical dispersion. As the system is used for music and small concerts, in addition to its prime function of speech reinforcement, compact dual 12-inch Community VLF212 subwoofers were incorporated to extend the low frequency and add powerful bass performance.

Providing flexibility with simple control, Tevean installed a Symetrix Solus 8 open architecture 8×8 DSP with control via a Symetrix ARC-2e menu-driven wall panel remote. A variety of Clockaudio and MIPRO ACT-5 wireless microphones meet the fixed and portable requirements of the church.

Mario Clabots, managing director of the equipment supplier, M-Pro, commented, “The client and visitors are very pleased with the excellent audio quality, wide coverage and sound levels the system provides. It achieves very high intelligibility right to the back of the church and delivers the ideal solution for both speech and music.”

Martin Audio OmniLine® Conquers High Reverberation In Award-Winning Installation At Sydney Railway Terminus


A Martin Audio OmniLine® system has been specified and installed at Central Railway Station in Sydney, the largest in Australia, to conquer a speech intelligibility problem that has persisted for years.

The Country Trains Concourse, measuring 360 ft x 196 ft x 32 ft with a challenging RT60 time of 5.5 seconds in the mid-band, has long defied attempts to get intelligible announcements heard by commuters. Over the years, many brands have successively tried and failed to tame the inherent reverberation caused by a combination of terrazzo floors, sandstone and plate glass walls and a high arched steel roof.

Last year Glenn Leembruggen, principal of Acoustic Directions, became the latest specialist to do battle with the acoustically hostile environment.

Since acoustic treatment of the inside of the roof was ruled out as being financially untenable, two members of the Acoustic Directions team, David Connor and David Gilfillan, decided to trial several software-driven systems and different steerable line array solutions.

They ultimately concluded that a Martin Audio OmniLine system, with DSP processing, would produce the best quality and best speech clarity. They duly specified 120 steered elements supplied by TAG, Martin Audio’s Australian distributors.

Modular and scalable, this particular OmniLine installation used a special version of the Martin Audio Display software (operating under an FIR filtering scheme that addressed every element in the array with its own processed channel). The intelligent software enabled the array to be configured to deliver sound precisely over the venue’s vertical profile without spillage. Furthermore, elimination of high-frequency side-lobes gives OmniLine an advantage over conventional DSP steered columns making it suitable for high quality speech and music reproduction even in reverberant spaces such as railway station concourses.

Acoustic Directions were thus able to simultaneously optimize the direct field over the listening area, keep the sound off reflective rear walls, and minimise reverberant sound power. The result is remarkably high intelligibility throughout the concourse, even at rush hour, when as many as 3,000 passengers are adding to the cacophony of noise resonating around this vast cavern.

With the amps situated as much as 650 ft away from the speakers, a 100 Volt system was required, and Acoustic Directions worked with Harbuch Electronics to develop a 100V loudspeaker transformer that was ultra-flat and with only 10 degrees of phase shift at 20kHz. The FIR filters that beam control the array are implemented in Nion processors with the loudspeakers being driven by 8-channel 2.4kW amplifiers (to provide 120 amp channels).

Acoustic Directions optimized the frequency responses over the listening area using time-windowed impulse responses.

The installation also picked up a coveted Rutledge AV Industry Award (an AVIA) with the judges commending Acoustic Directions’ meticulous implementation of the modelling, installation and commissioning of the system.

As a result, for the first time not only can amplified speech be easily understood in any part of the concourse, but music and pre-recorded messages sound natural and clear—and roaming hand-held wireless microphones can function without fear of feedback.

In fact, such is the confidence inspired by this new solution, that special events, promotions and even live music events are being hosted at Sydney’s Central Railway Station, using the house system!

About OmniLine®
OmniLine is a versatile, micro-line array designed for installation in a wide variety of architectural environments. Its modular approach and scalability extend its use from foreground applications to sound reinforcement in large acoustic spaces. Intelligent software enables an array to be configured to deliver sound precisely over any vertical angle to fit the venue profile without spilling onto surfaces where sound is not required. Additionally, elimination of high-frequency side-lobes gives OmniLine the advantage over currently available DSP steered columns, making it suitable for high quality music reproduction as well as speech in large, reverberant spaces. Each array is constructed by connecting multiple modules. Up to 32 modules can be connected where both high output and vertical focusing down to low/mid frequencies are required. Smaller number of modules (down to 4) can be used for shorter-throw applications, where vertical focusing of the low/mid frequencies is less important. This scalability means that OmniLine can be used in a variety of applications. Visually, an OmniLine array is slim and unobtrusive, with soft lines that minimize its visual presence in an architectural environment.
