What is the point of these things if you can't run anything off of them without tripping the circuits? EVERYTIME we play a gig where these are what the venue uses, we have issues.
One of our soundguys has suggested that there might be something in our wiring---could be something as simple as a mic cable that isn't grounded properly---that is causing some of the problems, but that there would be no way to effectively trace it at a gig. I don't know enough about that sort of stuff to know if that makes sense or not.
But we played a gig last weekend---beautiful venue---and nothing but GFIs. We were supplied with a spider box for power with nothing but GFIs. 4 circuits and we're constantly tripping one of them that half the PA was plugged into. Soundguy resolved the problem by the 2nd set by finally just turning down the low-end, but sacrificing our sound is NOT the solution, IMO.
Another soundguy suggested we insist on "no GFIs" in our contracts, but obviously that isn't going to happen for the type of gigs we do and the venues we play.
I hate these things. Anyone have trouble with them? Or suggestions on how to figure out if it IS something in our setup causing an issue?
