Life Change Church Seattle - New System

Life Change Church Seattle

Associate Pastor Art Nelson would like the room to sound like a recording studio control room. His comment on the existing system: It has a mushy bottom end, with it sounding very different depending on where you sit in the seating area.

Project: Upgrade Sound, Video, Acoustic Treatment, and Lighting

Design Parameters:

  • Acoustics - room to have a sound signature similar to a recording studio control room. Adding bass traps, panels and diffusion. (see drawings below)
  • Sound - Total new system, converting to digital, centered around a Midas M-32 mixer with 48 channels to platform. Speaker choice is the ISP HDL 3112 3-way line array with the ISP XMAX 212 Sub Woofers (all active) XTA processing and installed in a LCR configuration.(see SketchUp drawing below)
  • Lighting - All new lights to be LED including house lighting. Some par fixtures and a lot of robotics.

Existing System:

  • Acoustics - None, no acoustic treatments of any kind in the existing room.
  • Sound - 2 x EAW Passive MK Series Club Speakers, Mackie SWA 1801 Active Sub Woofers, QSC amps (mains & monitors), Mackie SR 32-4 VLZ console, 4 stage pockets with 8 x XLR & 4 x 1/4” connectors.
  • Lighting - House light consist of residential hanging globe fixtures and track light for stage area.
  • Video - projection system on to a painted-on-wall screen in 4:3 format approx. 100” diagonal
  • Room size is 40’ x 40’, so this is a small room and their is a lot of energy put into the room from this system. The speakers are mounted in center cluster configuration, running mono. No processing of any kind, and amplifiers are located at the sound booth.
