The loudspeakers are configured into multiple zones, allowing the A/V staff to turn various sections off and on depending on what's needed for a given event. Dietze adds: "We only had a single 3/4-inch conduit to run wiring through, so we converted the signal to digital using an Aviom Pro64 encoder in the rack, and another in the Yamaha LS9 digital console. That enabled us to carry the signal on a single Cat 5 cable. The only connection to the console rack is two pieces of Cat 5 and power cables. It solved any potential grounding problems as well."
