I’m trying to set up a system where the vocalist in the recording booth can control the instrumental and monitoring volumes separately (not to mention giving that same control to the audio engineer in the control room).
Is there a guide on the manual or somewhere here that I can refer to?
Normally you’d set up a cue channel in the control room for the headphone feed in the vocal booth.
The issue you are going to have is how to let the vocalist control the mix remotely - normally you just ask them if it’s ok…and if not change it yourself in the control room.
An alternative (and better IMO) is to invest in something like the Behringer (I know but these actually work ok!) Powerplay P16 system and the vocalist can adjust whatever he likes.
