I am having problems trying to integrate home audio system with pro gear. I am trying to use an EV DC-ONE to actively filter my Klipschorns. Here is the situation.
Goal: Be able to actively cross my Khorns with an EV DC-ONE.
Setup: Integra DHC 9.9 pre/pro source ( balanced), to EV DC-ONE (balanced), to Parasound HALO A23 and A52 amps (balanced), to Khorn drivers. Two in six out setup.
Problem: It all works, but I get loud hissing from the mid and tweeters when the system powers on and can be heard anywhere in the room without music playing.
The system is very quiet when amps are on and nothing else if I take the EV out. When I turn on the EV, the hissing starts. If I mute the EV channels, the hiss is still there. I have guessed this is a gain matching problem. The A23 has gain knobs and when I lower the gain a little on the amps, the hiss goes away. Problem is the A52 doesn't have gain knobs.
So, I decided to try going XLR to RCA on the EV output so I can use a Parasound HCA-1205 5 channel amp that has gain knobs, but no XLR inputs. I got the cables, but they are picking up some wicked RFI. These XLR to RCA cables have pins 1,3 and the XLR case hooked together going to the RCA shield. Pin 2 is going to the center RCA pin.
Bottom line is I'm between a rock and a hard place. If I go all balanced, I get noise floor hissing. If I go XLR to RCA, I get terrible RFI.
Any ideas on how to solve this?
