The hum is there when the DSP is connected to the Amp. It does not matter if it is turned on or off. Even unplugged with not power cord attached to the back of the unit, and completely disconnected from the pre-amp. I still get the humm.

I did not budget nor do I have very long RCA cable to try and put the DSP on the other side of the room from the rest of the equipment. It was never discussed with my by Brent when I inquired about the unit that it would humm if connected.

I get the distinct feeling that there must be some form of short inside the DSP that causes this buzzing humm on the speakers.
