Just finished the last connection on my system. Connected sub the same way it used to be with my new Yam 2700 sub pre out. The reciever MASTER power ON or OFF HUMMing from sub ONLY when plugged into reciever or anything else. Level on sub doesn't matter. I reversed the cable (and tried another) and the same thing. It happens when the audio cable is plugged into the input OR OUTPUT of sub as long as the other end is also connected to something. Tried UNPLUGGING all power cords exept sub. Still happens when audio cable is connected.
I'm afraid sub was damaged in move.
I did a test. Connected sub to cd changer. Changer has video connection into tv for on screen display. Disconnected video connection to tv NO HUM, connected has hum. Plugged back into reciever STILL hum. Possibly bad video connection (shielding) someware in setup. I don't know.
