What's up. I'm searching for some advice to assist me install a wireless speaker. Excuse me in the event I'm not in the appropriate thread. To avoid speaker cable clutter, I have acquired a 5.8 GHz wireless loudspeaker system for my surround speakers. The transmitter hooks up to the surround receiver rear speaker outputs. Commonly the transmitter goes into stand by after a few minutes of not having acquired music. Interestingly, my AV receiver keeps giving off a hum whilst in standby. This prevents the cordless transmitter from entering stand by. That in turn causes my wireless amps to stay on all the time and give off a small hum via my rear speakers. This sound isn't present when my audio receiver is working, i.e. active. I have been considering putting in some form of switch to detach the audio link between my surround receiver and the cordless transmitter however this remedy won't appear to be sophisticated. I would appreciate any kind of suggestions.
