Mixed Mono Mode
The Mixed Mono feature allows performers to adjust the balance of the Left and Right audio signals sent from the transmitter right on the body pack.

With Mixed Mono:
- the performers can have their vocals in Input 1 and the band mix in Input 2 and adjust the volume of each independently to create their own personal mix, or
- you can send two different monitor mixes from the board so each performer can decide which mix they want to hear on their belt pack.
