Here's a good one...


I put a Boes sound system in my room (2 small, high/midrange speakers and a subwoofer). the speakers are run into an old Pioneer reciever that's probably 25 years old. At seemingly random points in time, i will notice a signifiact loss of power to the speakers in the form of muffled sound and crackles of lower frequency sounds. Here's the interesting part: the problem is corrected when i turn the overhead light off while keeping the fan on. then if flick the light swith off, then on, the speakers emit a pop, and full power is restored. anybody got any idea about that?
Thanks for your time.

Poltergiest?

Sounds like you have some audio wires that are run parallel (maybe used the same stud holes) as your 120v wires. This makes it possible for the electrical field in the 120v wires to affect the audio signal wires. Sometimes you can get away with this, sometimes not. Audio visual cables should be kept well away from line voltage cables, especially when they run parallel for any distance.

I agree with Troubleseeker. If your speaker wires are near an AC line it can cause that. I've seen it do wacky stuff to access control systems before. Especially if the wire is coiled up or runs near a flourescent light.

Try doing a temp run to the speakers staying away from the AC voltage.
If that corrects it you may need to change the permanent speaker wiring to a wire with an overall shield.
