I'm trying to troubleshoot a *hiiisss* emanating from the speakers when the C1 and A51 are connected and powered up. At a steady state (no inputs playing), the hiss is actually quite loud ... one can hear it from all 5x speakers quite clearly, even from a distance of 10'!
Tried toggling the ground lift on the A51, and even a cheater plug (yes, I know the latter does the same thing, just tried it to be complete), but no effect on the hiss.
Upon disconnecting all inputs into the A51, though, the hiss is *significantly* reduced. Here's where it gets interesting - the C1 & A51 were connected with balanced (Monster XLR) cables; when replacing these with unbalanced (RCA) cables, the hiss againg is significantly reduced (though still somewhat louder than with nothing connected to the A51)!
Very odd - and makes me wonder whether there may be an issue with the C1's balanced outs? Any thoughts/suggestions would be appreciated!!
