[QUOTE="Lisa Lane-Collins, post: 99178, member: 2967"] Re: Dirty power wrecking the sound... Why yes, that's exactly what it has. Does kinda look like it left the factory that way. Of course, now I am puzzled how it is meant to ground. Tried plugging in a different mixer and that was fine, no shocks. Then the 800 again and that was Also fine. By this point in time I'd been messing around with the patching at the amp end a bit though so maybe the problem came from there. Whatever was causing me to become the ground, it isn't anymore :-D. The signal flow that Worked in the end. DJ mixer - balanced out - adapted to rca using a specifically made cable that summed black and ground (instead of black and red as I now suspect the adaptor was doing) - zone control - amps. The difference between using the tailored cable and the store bought adaptor (or even the Isolation box - gah waste of cash!) is night and day!!!! Another thing discovered, the DJ mixer has a master attenuation control at the back of it, wound that up and got quite a bit more volume that way. So, not the power that wrecked the sound in the end at all but quiet source signals, unbalanced outs and unsuitable rca to xlr adaptors. Feeling quite proud now :-D (and my prize - not having to set up a second PA in that room for salsa dancing, an Excellent prize!) [/QUOTE]
