i'm installing a new system and have found that some of the gear needs
the signal ground lifted. should i do this at the patchbay or the
gear side?

what should be done about the mixer (balanced) to pathcbay connection
(all mixer i/o go to patchbay) ?

-i've read that grounds should be connected at mixer and lifted at gear
but i'm not sure how this applies when a patchbay enters the situation.
