OK. Well I searched all the way back to 2006 and didn't find something which would point me in the right direction so here goes... Just modded old 16ch Soundcraft Spirit Studio board to +4 from -10. Now the static (which has always been there) has increased. Here's what's been done up to this point: -Proper electrical ground -Furman conditioner -Adequate signal to noise ratio. -Climate control on separate circuit. Is there a cost effective way to remedy this situation? Should the computer be on a separate conditioner (or ?) from the outboard gear? Does pluging a power strip or two into the Furman encourage static? Seems like the static drops considerably when the computer and Delta 1010's are off. Any suggestions? I forgot to mention that I've routed power cords away from audio cords as much as possible. This static is loud enough that it is showing up on my meters.
