hi, i have a mic pre that i had racked previously with the output ground lifted, and it sounded fine. my question-i just found the matching eq from the console, and intend to re-rack with the mic pre output hard-wired to the eq input, and then the eq out wired to an output. so....im assuming i should lift the ground on the eq output. what should i do from the mic pre out to the eq in? ground lift or shield to shield?

ps-i know i could try it either way and listen, but taking racks apart can be a pain, and you guys are pros, so i'd like to at least start at a point that is sensible. thanks a lot!!!

Assuming proper balanced inputs and outputs (which includes no "pin 1" problems), then the correct answer is: don't lift the shields at all.

And don't lift the AC mains grounds, either.
