Long Beach Arena’s Pacific Ballroom is Covered by Renkus-Heinz

Long Beach, CA – February 2014…Covered on the outside by one of the world’s largest murals, “Planet Ocean,” The Long Beach Arena is an unmistakable part of the city’s skyline. Built in the early 1960s as part of the greater Long Beach Convention Center, the Arena is also an unrivaled cornerstone of entertainment in Southern California, hosting events ranging from the first NHL game in 1967 and the 1984 Olympic volleyball tournaments, to acts as diverse as Cirque Du Soleil, Iron Maiden, Run-D.M.C and Disney on Ice.

The Arena’s Pacific Ballroom, along with the rest of the Convention Center, has recently reopened after a massive series of renovations. The Ballroom’s new state-of-the-art audio, lighting, and curtaining system — the largest ceiling grid in the country — has been recognized by Venues Today magazine with an Ops and Tech Award. The system has helped to transform the Arena into even more of a multi-functional venue, enabling the 46,000 sq. foot, 200 foot long elliptical floor to be partitioned for use without the surrounding arena seating, and arranged in a wide range of configurations.

But while the curtain does wonders to partition and conceal the arena seating and frame the flat floor, it does little for the acoustics of the space. Indeed, the Arena’s vast acoustics presented a challenge in finding a sound system flexible enough to meet the demands of its wide-ranging roster of events.

Working with architectural firm John Fisher & Associates, engineering firm JR Clancy, and installers Pro Sound, Burbank, CA-based Electronsonic created an audio system to address the Arena’s diverse needs. The system, which mounts on a moveable ceiling grid, comprises left and right hangs of ten Renkus-Heinz IC2 digitally steerable array cabinets per side. Each array is augmented by eight IC118S subwoofers for low frequency power and punch. As Electrosonics Andy Batwinas explains, it’s a concept that has never really been implemented on this scale.

“The grid itself can lower to 30 feet for smaller events, and raise up to 70 feet for games and larger events,” says Batwinas. A series of connection points allow the speaker arrays to move around the grid depending on the desired configuration. Once in place, the IC2 arrays’ digitally steered beam technology enables them to be configured to cover only the areas needed, steering sound away from the hall’s reflective outer areas. The grid can also lowered and removed for events like a Cirque Du Soleil show, providing full access to the 75-foot ceiling, and the IC2 arrays can be removed from the grid and ground stacked as well.

“The IC2 delivers such even sound pressure level from front to back,” Batwinas says. “When we did the demo, it was set up at the far end of the arena and shot down the long way. You could walk the whole space, cover the floor, and keep it a solid 98 db SPL from one side to the other.”

The system is networked using RHAON control, enabling the Arena’s technical crew to implement preset coverage configurations for different event needs, and making quick changeovers possible with the press of a button.

“The IC2 steered beam technology made it a vastly superior alternative to a standard line array system,” Batwinas observes. “With the IC2 you can aim the sound down to the floor so it’s not bouncing off the architecture.”

Based on the success of the IC2 system, a Renkus-Heinz system of 18 VARIA modular point source arrays and 12 VA15S subwoofers was added to cover the Arena’s 19,000 square foot Lobby area and 29,000 square foot concourse. The VARIA’s modular design and variable dispersion patterns enable the systems to be custom configured for the area’s different ballrooms, theaters, halls, and atrium. Additionally, 16 CFX81 loudspeakers were installed in the ceiling of the Arena’s lobby for added foreground coverage.

The Long Beach Arena’s grand re-opening on November 20, 2013 met with rave reviews, and the Ballroom boasts a full calendar and an exciting 2014.

Sochi Olympics Sound Better with Renkus-Heinz

Sochi, Russia – February 2014… The Sochi Olympics have gone to the history books, and as is always the case, the brief few days the games are held belies the immense time and effort preparing for them. In Sochi, a dozen new world-class venues have been erected for the games, and outfitted with high-performance audio, video, and lighting systems.

Avallon, Ltd of Moscow designed and installed multiple Renkus-Heinz systems in no fewer than five Olympic venues. The most prominent project was the Arena Isberg, home to the figure skating and short track competitions. As Avallon President Sergey Vashchenko explains, it was also the most challenging.

“Since music is such an important part of the performance, figure skating competitions have some of the most stringent sound requirements,” says Vashchenko. “Even after working with the building’s designers to reduce the reverb time from 7.5 to 3.2 seconds, we still knew we need to create a system with great performance and tight pattern control, to keep the reflections under control.”

The audience seating is covered by eight each Renkus-Heinz CEM61 and CEM62 high power CoEntrant mid-high modules, with eight CE-3TLO subs covering low frequency reinforcement. The systems are hung around a central Media-LCD display. Ten CT7M TRAP boxes provide music to the skaters on the ice.

“During the EASE acoustic modeling phase, we looked at a number of options, including more traditional line arrays,” says Vashchenko. “But we were not happy with the difference in sound quality between the audience and the ice. Moreover, there was some concern that a line array might block the sightlines for some of the upper-level seating. The optimal solution was to mount all the speakers on the video screen frameworks, and the Renkus-Heinz CEM and CT series speakers offered coverage patterns that suited this arrangement very well.”

Power and signal processing for the systems is covered by Dynacord DSA-series multichannel amplifiers and P64 matrix processors. Amps and DSP are located within the signage frameworks, to reduce cable runs and assure low impedance. Audio signal is fed via fiber from the Stage Tec Auratux 16-T2Z digital console. “We assembled the entire system within the framework while it was on the ground, which made things a bit easier,” says Vashchenko.

Acoustical measurements were carried out by consultant Yury Indlin of ADI in Irkutsk. Vashchenko designed the system, with installation and commissioning by Avallon’s Vladislav Azarov.

“During the competition, sound levels are limited to 85-87dB,” says Vashchenko. “But during testing we were able to achieve levels of 103dB, with even coverage across the entire facility.”

At the Arena Fischt, home of the Olympics Opening and Closing ceremonies, Avallon installed six Iconyx IC7-II mechanically steered array systems in the VIP lobby, as well as a pair of PNX-82 two-way Complex Conic loudspeakers in the Press Center. And the Training Centers for Hockey and Figure Skating are both outfitted with multiple TRX151 two-way systems.

“It was a great pleasure to work with the Renkus-Heinz system,” remarked Vladislav Azarov. “I’ve heard many good things about their patented wave guides, but this was my first experience using their products on a large-scale project, and it was awesome. I’ve had so many great comments about the sound quality, from the athletes, from the spectators, and even from the heads of the Olympic Committee.”
