Well I'm doing the layout for a headphone cue system and I am trying to remember a few things. Using a regular power amp we have unbalanced L and R. So I am planning to use a 4 pin XLR at the wall in the live room. Then make a breakout box that goes from 4 pin to several 3 pin TRS jacks for headphones or maybe XLR and putting XLR connectors on the headphones. Anyway I know the grounds get shared to get down from the 4 pin to 3 pin.
1. which pin gets L hot and which pin gets R hot?
2. what would be the easiest way to add a volume control? I am thinking a stereo pot before the TRS jack. It would be passive but would be inexpensive or is that a bad approach?
