This is my first post - so hello to everybody! I have a problem with one of my studios and wondered whether anybody would be able to shed some light on my issue! We have a problem with fairly drastic gain output drop when we patch any outboard equipment through the insert/return points on the patchbay. We have a multicore from the Soundcraft Ghosts' insert point (Tip=Hot) going into a Bantom Patchbay (no rear connectors - soldering onto patchbay) with return and screen on the bottom patchbay (S and T repectively) and the send to the top patchbay point above (also on T) and half-normalised. On paper, this seems correct with patchbay and mixing desk manuals. (unless anybody tells me different and the manuals are wrong?!) Anyway, it is not the desk because we can patch some insert cables direct from the desk into any of the compressors/gates etc - so it has to be a patchbay/wiring issue. is there something i've missed here? Or are there any recommendations as to what to try? Any help greatly appreciated - before I go bald!
