I'm having some problems with subwoofer humming I can't figure out. Ive tried to plug the sub into different outlets, unhook every source from the receiver, unplug the cable box, and used a ground loop isolater from radio shack. Nothing has worked. I also tried connecting the subwoofer to the lfe input and the sub/sat input. The sub/sat input had less buzzing but was still noticeable. Anyone have suggestions?
The sub does not hum when turned on and not connected to receiver.
Also, what is the sub/sat input for?
The subwoofer is a dynaudio sub 250.
