I have an approximate radial setup but the mixer would be the hub. Thing is and as I said, I've tried to

use some of these things in isolation. (only the zoom H4 or only the mixer, both have integral monitoring so

no need for an amp or pc) but I still see it. (well, hear it)

well AFAIK, the house is grounded and being in the UK the sockets are all 3 pronged. that said, I'm pretty sure

that non of them use the 3rd prong. (plastic tab instead of a metal prong or 2 core flat cables)

hairstyle.
