this new place i got has,i would say possibly destructive static electricity. enough sometimes to send a loud spike through the PA when i move the master sliders.i tried a humidifier..doesn't seem to help. also get them of the mics and just about everything else but not always..usually when i first fire up the system, for the first hour or so, then it's o.k. the house circuits are good, every plug tests correct, no funny daisychaining going on.. i am thinking of hooking up ground wires. one to the amp rail on my rack as all the outboard gear is grounded to the amp rail. one to a body screw on the zed r16. and one to the body screw of my amps. then twisting the the 4 ground wires together and grounding it to the water pipe where the house earthground is. it works for cars with that strip dragging on the ground. can anybody think of a reason i shouldn't try this. i can't think of one but im not shure. anyone ever run into this. anything else that might work?
