A Meyer Sound Constellation system is providing variable acoustics for Eastside Christian Church in Anaheim, California – a house of worship which outgrew its previous location and moved in 2008 to a reconstructed Boeing Defense Systems plant. The 1,765-seat church, which presents a contemporary worship band and musical events, also uses Meyer Sound's MICA line arrays and D-Mitri digital audio platform.
One of Constellation's uses is to lend a sense of small-room intimacy to the teaching segments of senior pastor Gene Appel and others. “The main benefit of Constellation is that we can finesse it. We are not locked into a permanent acoustical decision as we would have been with a fixed acoustical ceiling,” said Chris Gille, Eastside’s CTO and chief systems engineer. Constellation’s effect on the room is strikingly apparent at all times, he added: “Just talking with the default settings on, the room feels alive, yet controlled.”
At the core of the church's Constellation system is a D-Mitri digital audio platform comprising three DVRAS processors for the three acoustical zones, plus six additional processors for core processing and analogue input/output. Thirty-two miniature microphones are deployed for ambient sensing of the physical acoustics. Constellation is also supported by a total of 80 HMS-10 cinema surround, MM-4XP, and Stella-8C installation loudspeakers, and eight M1D-Sub subwoofers, in addition to loudspeakers in the sound reinforcement system.
An idea of Gille's was to let the main reinforcement system automatically adjust the Constellation-generated reverberation time, in response to the level of amplified sound in the room. “When the desk drives the mix to a certain threshold, Constellation subtly pulls back the strength parameter,” Gille explained. “When the mix is loud, the room dries up just a touch, helping to clarify detail and widening the stereo image from the main arrays.”
The sound reinforcement component features main left and right hangs of eight MICA line array loudspeakers each, supplemented by a total of 10 additional UPQ-1P, UPQ-2P, and UPJunior VariO loudspeakers. Four 700-HP subwoofers are placed under the stage. The entire system is controlled by a Galileo loudspeaker management system with two Galileo 616 processors.
Feeding the front end of the system is an Avid D-Show digital console. Wireless microphone systems are Shure UHF-R, with seven handhelds and seven beltpacks equipped with DPA and Countryman headset mics. Six channels of Shure PSM900 wireless in-ear monitors supplement both an Avid VENUE Personal Q and an Aviom personal monitor mixing system.
AV, lighting, acoustics, and room design consultant for the project was Dallas-based Acoustic Dimensions. TC Furlong of Lake Forest, Illinois supplied the Constellation and sound reinforcement system and participated in the system’s design process and commissioning. System integration was provided by AMT Systems of Santa Clarita, California.
