imgLong Beach, CA (February 25, 2014)—The Pacific Ballroom at the Long Beach Arena was recently upgraded with a new audio system by Renkus-Heinz as part of a massive renovation of the entire Long Beach Convention Center.

Burbank, CA-based Electrosonic designed the audio system set up with the help of architectural firm John Fisher & Associates, and engineering firm JR Clancy, creating a system that mounts on a moveable ceiling grid, comprises left and right hangs of 10 Renkus-Heinz IC2 digitally steerable array cabinets per side. Each array is augmented by eight IC118S subwoofers for low frequency power and punch.

"The grid itself can lower to 30 feet for smaller events, and raise up to 70 feet for games and larger events," explained Andy Batwings of Electrosonics. 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 system is networked using RHAON control, enabling the Arena's technical crew to implement preset coverage configurations for different event needs, and make changeovers.

Additionally, 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.
