Audio-visual systems integrator CCS Presentation Systems recently upgraded the Murphy Canyon Chapel, located in the Aero Ridge community of the Murphy Canyon Military Housing complex in San Diego, CA, with a package of equipment from QSC Audio.
The upgrade includes a Q-Sys Core 250i integrated system platform controlling KLA line arrays and K Series K10 active monitors in the main chapel, with AcousticDesign surface and ceiling-mount loudspeakers powered by ISA Series amplifiers in a smaller chapel and a community room.
CCS Presentation Systems provided design and integration, which also included a new control system and touch panels as well as video projector and screen improvements. A QSC Q-Sys Core 250i with four mic and three output cards located in the building’s central control room provides signal distribution.
“We got a lot of help from our local representatives, Audio Geer,” says John Hardman, account executive at the company’s San Diego office. “They are audio specialists so, particularly with a main room of this size, we brought them in to consult with us,”
Audio Geer’s Mike Cromer recommended QSC Audio’s KLA active line array system. CSS installed two hangs of three KLA12 12-inch, two-way powered, line array loudspeakers, finished in white, suspending them from the ceiling structure. In addition, two QSC K10 two-way, active 10-inch speakers were placed in the chapel’s stage area for monitoring on.
“I suggested the QSC KLA system because it was a great solution for this project – the simplicity with which it could be installed, the lack of tuning that it needed once it was flown and the overall coverage were perfect for that room,” says Cromer. “The fact that the arrays were available in a white finish was another positive factor for the client. And, because KLA loudspeakers are incredibly power efficient, only two 20-amp AC circuits were required for the install.”
“The principal problem was that the main chapel had old analog equipment that had been in there for 15 or 20 years,” Hardman adds. “We were replacing gigantic old speakers that had no real coverage. The whole thing needed to be upgraded and brought up to modern specs. It’s a large, hexagonal, very open structure with a very high ceiling, so we needed a speaker system with a wide spread that could be fairly easily directed.”
For the building, which acts as an ecumenical and community center for military base personnel, CSS installed QSC AcousticDesign surface- and ceiling loudspeakers.
“We installed a pair of white AD-S282H two-way, full-range, surface-mount speakers in the small chapel and six AD-CI52ST two-way, high-fidelity in-ceiling speakers in the overflow room,” says Hardman. “A QSC ISA500Ti 70V amplifier powers the speakers in the overflow room while an ISA750 two-channel amp drives the system in the small chapel.”
CSS made a variety upgrades to the video systems, he continues, “We repurposed a couple of rear-screen video projectors that were in the main chapel, and installed new projectors and screens in the overflow room and the new chapel that have the new wide-screen formats.”
Touch screens in each of the three rooms plus a main control panel enable easy preset operation of the installed AV systems. A digital mixing console and multiple DVD machines in the control room for AV recording and playback also feed the system.
