[QUOTE="Greg Cameron, post: 98957, member: 42"] Re: Dirty power wrecking the sound... If you're trying to use a regular DI, it's doing to drop the level to mic levels which won't be enough to drive line level inputs. You need line level isolation transformers, not a DI. Something like Whirlwind ISO1/ISO2 or the good Jensens. I believe the level drop is no more than 6dB. Sounds dangerous and potentially deadly. Get a [i]qualified[/i] electrician in there ASAP to figure out the mess. Could be what JR said, a hot - ground swap or some other crazy stuff. It will also create huge noise problems as well as possible death. There might be other problems as well like ground neutral swaps or appliances on the circuit leaking current into the ground. Again, an isolation transformer that is able to go from balanced to unbalanced would be the best way to isolate ground loops, maintain correct impedances and keep the XLR signal balanced. The ISO1 can work as a balanced to unbalanced box as well as a line balancer.
