I introduced the Minidsp 2x4HD into my system today and have an annoying humming from the system subwoofers. I've isolated the humming down to Output 3 and output 4 which use RCA from the minidsp outputs to my active subwoofers inputs. Output 1 and 2 which go to my Parasound amp to the mains do not produce the hum.
If unplug the RCA from the outputs of the minidsp to my subs the noise goes away. When I plug the RCA back into the minidsp the hum is back.
Likewise w/ the RCA connected and I unplug the power supply to the minidsp so dsp is off the hum is still there.... if I unplug the RCA to the active subs the hum goes away.
I've also tried plugging in power from all gear into various other outlets or the same outlets on an Emotiva power strip.
Note, this noise wasn't present without the minidsp.
Any help would be appreciated as the hum is loud enough that the active subs won't auto turn off.
