Cause of speaker static?


Forgive the elementary nature of this question: what is the most likely source of low-level speaker static that is unaffected by volume control of pre-amp? System bi-amped, static created by both amps. Goes away when pre-amp shut off. Thanks.

stooges (are you 1,2 or 3?): are you using a toob amp/pre amp or what? -kelly
Rare is the system that is stone silent when running. Probably just system noise from the amplifiers and preamp. Tubes are ususally a bit noisier than SS. Unless you can hear it from 12 feet away with nothing playing, don't worry about it. Otherwise, something is probably wrong with a component or interconnect.
Stooges. If you are attaching any VCR to the preamp, this could be the problem - related to the cable input to the VCR . Try removing this VCR input and see whether the noise goes away. I had the same problem, and found the TV/VCR connection to my system to be my problem. Cheers,
John.
