help with behringer feedback destroyer and amplifier noise

noodle_snacks · 11th July 2006, 12:20 PM

I am having a bit of strange trouble with noise and my behringer feedback destroyer pro that i just aquired. Basically one channel of my amplifer, with the feedback destroyer in the circuit has quite a lot of electrical noise (from my computer, and a bit of hum). Switching cables and around and whatnot doesn't fix the problem. When i unplug the digital rca going to my computer, the noise goes away.

What is strange about this problem, is that only one channel of my amplifier is afflicted with this issue, sort of getting a sound card with optical out, does anyone have any solutions that i could try for this problem?

My amplifier is a Beima 2 X 300W amplifer being used to power two subwoofers.

Running an aligator clip from the case of my BFD to the shield on my yamaha (ungrounded) amplifer, just about fixed the problem except for a very minor amount hum, any ideas for a more permanant fix? What is this acutally doing ?
