Auto Gain
This can be used independently of Auto Set and turned on or off at any time. Auto
Gain constantly checks the input signal level in the background and if the preamp
gain is set too high (e.g. an instrument or voice get louder than they were during
sound check), it will reduce gain until the signal is back to an optimum level.
Multi Select
Use Gain Assistant functions on multiple preamps at the same time with Multi
Select by simply turning it on and then selecting the desired channels; Input
Source and Gain Assistant settings will then be available at the bottom of the
screen.
