New York (November 3, 2006)–The ‘worship experience’ seems to get more high-tech every day, as parishoners across the country are coming to expect something akin to a multimedia extravaganza when they head to church every week. The new 4,200-seat worship center at Resurrection Life Church in Grandville, MI is certainly an example of that process, in terms of sound reinforcement technology.
Resurrection Life Church technical director Cliff Rosenberg (standing), building project manager Doug Sluiter, and Gary Zandstra of Parkway Electric at the church FOH position.A cohesive team recently created an extensive system to serve the new two-level, fan-shaped worship center that resides just outside of Grand Rapids, MI. Acoustic Dimensions (Dallas), provided both system and acoustical designs, with installation handled by the Communications Division of Parkway Electric (Holland, MI), both working closely with Resurrection Life Church technical director Cliff Rosenberg and building project manager Doug Sluiter.
The top priority for Rosenberg and Sluiter was a system that would include a digital console, but which could also be expected to be run by a group of volunteers. “Almost immediately, I could see that the DiGiCo digital console format holds a lot of appeal, and for several reasons,” Rosenberg said. First citing ease of use, he also noted the ability to interconnect DiGiCo desks without complicated network interfaces. Each console’s stage rack is outfitted with analog to digital input/output cards feeding a termination port for linking via fiber optics or CAT-5.
Filling the huge worship center with concert-quality audio produced by the 12- to 20-member praise band, 200-member choir, featured vocalists and of course, spoken word, was another key facet of the project. The system team chose a main system loudspeaker approach based upon L-Acoustics Kudo line arrays flown above the gondola structure that hosts three large video screens above the front platform, supplemented by compact loudspeakers to bolster coverage to remote and/or shadowed regions.
Consultant Ryan Knox of Acoustic Dimensions utilized L-Acoustics SoundVision acoustical modeling software for an assist in formulating the positioning and layout of three line arrays, each with five Kudo enclosures. Low-frequency reinforcement is supplemented by three SB218 subwoofers also flown above the gondola, along with eight more SB218s housed in cavities carved out beneath the front length of the platform.
Coverage of the line arrays to the first few seating rows is supplemented by EAW AX396 full-range coaxial loudspeakers flown behind the gondola’s scrim areas that separate the high-resolution video screens. A compact EAW MQ1346 full-range loudspeaker also mounted on the gondola provides added reinforcement to seating at the far right of the worship center.
Above the balcony, mid-high presence is bolstered via more EAW AX396 loudspeakers mounted well up by the ceiling catwalks. The rear half of the seating rows under the balcony, shadowed from the main loudspeaker coverage, receive mid-high reinforcement from a dozen EAW UB82e low-profile loudspeakers that are mounted in “slots” cut into the balcony ceiling, minimizing their impact on sightlines.
All loudspeakers are driven by Crown I-Tech and CT power amplifiers rack-mounted with the system’s BSS London digital signal processors in an air-conditioned room at the ceiling catwalk level. Additional processing in select applications, usually for the system’s subwoofers, came courtesy of the DSP add-on option available with I-Tech amplifiers.
