How To | Room combining with the the MP-M series mixers
Learn how to use MP-M series mixers to combine multiple audio sources for a single output.
Procedure
You will need to setup two scenes, one for each state of "Uncombined" and "Combined".
The "Uncombined" state would require each output zone to be sourced independently.
The "Combined" state would have room 1 zone output be selected as the audio source for room 2 zone output. The user would need to be able to toggle each scene relative to the state of the room combination.
