Hi all. I am looking for some guidance to assist me set up a set of wireless outdoor speakers. I am sorry just in case I am not within the correct thread. My situation is related to the cordless speaker kit transmitter that I am utilizing for my surround loudspeakers. The transmitter won't ever go into standby when my AV receiver is powered down since my receiver will always give off a humming sound. Hence my rear speakers will keep sending out this particular humming noise anytime I am not watching TV. I've been contemplating how to fix this issue. One idea I had was to create a switch in order to cut the sound towards the transmitter or power down the transmitter (cut DC power) whilst my AV receiver is in stand by. However, I do not know how to pair this switch together with my AV receiver. Does anyone have any good ideas?
