My apologies should I be in the incorrect thread. I'm searching for some guidance on how to set up a wireless speaker system? My challenge is due to the wireless speaker set transmitter that I am employing for my surround speakers. The transmitter will never enter standby whenever my AV receiver is turned off since my receiver will forever emit a humming noise. The problem is that my speakers will keep sending out the same sort of humming noise while the AV receiver is in standby. Curiously there is no such thing as a hum coming from my receiver if it's active. I do not think that it's a ground loop problem. I have already been thinking about putting in some sort of switch to detach the audio connection between my surround receiver and the cordless transmitter however this solution will not appear sophisticated. I would love just about any suggestions.
