Splitting mic line signals
Posted: Wed Feb 09, 2022 10:05 am
Hey there, a little bit of an odd question I think because I haven't been able to find much about this online, but I'm sure it's a situation that people come across often.
I'm working in a small sized commercial facility at the moment with a small control room, a live room with 24 lines through to the CR, and an iso booth with another 4 lines through to the main room. There's also an adjacent B studio which isn't currently connected electrically to either the booth or the live room, and as part of our future studio plans I'd like to be able to record from either of the two rooms.
As we're working on a limited budget, i was wondering if I could add some sort of split at the pre-existing mic panels in both of the two rooms and allow either of the consoles to connect to these lines - kinda like how a split works in a FOH/Monitor situation. I do realise i'd probably have to add some isolating transformers on one side of the split, but I'm not exactly sure, hence my asking here.
Also I am worried I might run into issues with power grounding, and ground loops between the two rooms - I need to investigate if they're on the same circuit. Could this be fixed if I ran audio power from the first room into the second room, and ran all the interfaces/console off of that power while leaving computers and lighting on the preexisting electricity in the B room.
Just throwing stuff out there.
