Re: Logitech Z-680 Subwoofer to a receiver
Ok must be a ground loop, but a little confused if I remove the subwoofer cable the hum stops, which I expected that but say if I touch a metal part of the heatsink or the RCA jack it's self I can get hum again.
would that mean a bad ground? I wonder if I put the ground wire in between the wrong spot/
