Looking for any ideas on what may be the problem here. Due to the use our building receives, we have quite the sound system - 4 chapels each with independent audio feeds. For stake conference, audio from one chapel can source all of them. Same thing for CES firesides/satellite broadcasts.
This morning, there is no power to the microphones on half the building. The organs still play just fine, but the pulpit and sacrament microphones have no power to them.
What we've checked:
1) Circuit breakers in the chapel - all are on
2) Circuit breakers for that side of the building - all are on
3) Amplifiers - all are on, although 2 of the 3 have an orange light on something called "par". Not sure if that's an error or just an additional connection.
4) Digital signal processors - all are on
5) Audio mixers - one is on, one has no power.
6) Input expander - powered
I'm guessing the mixer, but would that kill sound in half the building?
Microphones not working

We just went through the same thing and yes, a mixer can take out a large portion of a facility. It really depends upon what kind of a system you have. If it's one of the newer digital (programmed) mixers they're running software that can be completely lost if the battery backup goes out. This sounds like the situation as your description mirrors what we saw.crislapi wrote:Looking for any ideas on what may be the problem here.

In this situation the mixer must be removed and returned to the manufacturer for service. I strongly recommend that you contact your FM group as they are responsible for the maintenance of the system. They will probably have a service technician come out who's familiar with the system.

Thank you for the rapid reply. We have confirmed here that it is indeed the mixer that went out. Luckily, it was just the power supply and not the mixer itself. We were able to play around with the power supplies and get half of the building working again. Once we replace the busted power supply, we should be back and running.

Good job of troubleshooting. I'd say that luck was certainly on your side.crislapi wrote:Thank you for the rapid reply. We have confirmed here that it is indeed the mixer that went out.

When our mixer went out we were without a portion of the building for a little over a week. Thanks for the feedback.
