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.
