I have never been more exhausted from trying to track down an issue. Let me describe the nature of the problem.
It started several days ago after I set up a sound system for a community theater musical performance. We are using 14 wireless microphones in total, some are Shure model, some are Audio Technica and a couple are Sennheiser. The system was left completely muted and idle. I was working on another project in the theater when a piercingly loud high-frequency whine filled the room. It went away a moment later. I went to the board and saw that everything was in fact, still muted. I sat by the board for a while and it happened again. Even though everything is muted, one of the receivers was getting such strong interference that it managed to push through the board anyhow. (To my understanding, in extreme cases, this is possible.) I changed the frequency on that receiver, and the problem occurred again, on a different receiver. I have spent the past few days shuffling frequencies again and again only to find that nothing I do helps.
The only receivers this seems to be a problem with are the Audio Technicas.
The theater is located in an industrial area, is there maybe some heavy machinery causing this interference?
There is no pattern to this problem. Sometimes it will happen several times in a minute, other times it goes away for an hour and comes back, at most times of the day.
Any clue? We have a show tomorrow, and I don't want to be responsible for causing ear damage to our audience...
