Note: The TRIM and MIC button status are two of the only controls that are not written into automation or snapshot data. That’s a disadvantage of analog circuitry, but these controls are necessary. Running a strip of white safe-release tape across the top label strip allows for careful recording of each channel’s TRIM level and MIC button status. This kind of tape can be removed and folded for storage with session documentation, guaranteeing accurate settings whenever you need to restore the mix.

6.In the CONTROL ROOM section, press the MASTER L–R button so the yellow light comes on. Assigning this button sends whatever is coming from the MASTER L/R fader to the selected speakers.
