Re: Theater Lighting / Audio System HelpNoticed a very similar thing at a church a while back. I was there working on some floor box jacks and heard buzzing coming from the monitors. I knew the system was powered down, completely disconnecting the speaker cable did not get rid of it. The inductors in the monitors where picking up the RF hash from the dimmers on the sanctuary lights. Changing the monitor position you could make it better or much worse, the monitors are JBL 712. The sound system is actually amazingly quiet, I have heard that the guitar players sometimes have noise issues, no big surprise there!
