Hi, we just purchased a Behringer X32 (sweet mixer!) for our youth sanctuary in our church, and I decided to re-do the PA system while we were at it. I've always remembered the speakers being very noisy (hum, etc.) when nothing was playing through the system (everything was muted). Trying to adjust the PA levels, I'm now beginning to think that who ever chose the speakers/amplifiers specified something that was way to powerful for that room. If I crank the FOH amplifiers down to the minimum setting (~10%) I get about 90-95db SPL using a cheap meter that I have, when the pink noise is approaching the clipping point of the mixer. Now there is no noise coming out of the speakers when everything is muted, but the amplifiers are cranked ALL THE WAY down. The subs are also barely on, and I'm considering only using one of them now. Same goes for our monitors. This doesn't seem right, can someone let me know if I'm doing anything wrong?
Our setup:
- 2x JBL PRX518s subs
- 2x JBL MRX515 for FOH speakers
- 2x JBL MRX512m for front monitors
- 2x JBL side monitors (will update with model number, don't remember but they are matched correctly with the amps)
- Amps for the FOH Speakers: QSC PLX3002
- Amps for the monitors: QSC RMX1450
Our youth room fits about 90-120 people. I can provide the dimensions of the room if needed.
