Hiya, I am not sure if I am in the correct forum thread however I am trying to find a few ideas in order to help me resolve a problem with http://ezinearticles.com/?Understanding-The-Output-Power-Spec-Of-Modern-Audio-Amplifiers&id=6507319 ' TARGET='_blank. My problem is because of the cordless loudspeaker set transmitter which I am using for my surround loudspeakers. The transmitter can never enter standby when my AV receiver is powered down as my receiver will always send out a humming sound. Thus my rear speakers will keep sending out this particular humming sound when I am not watching television. I'd appreciate it if any person might provide some suggestions concerning how to deal with this issue.
