When a chairman override channel is
gated on, all non-chairman inputs are
gated off.
Adaptive Ambient mode
On/off Automatically sets the ambient audio
level of the room averaged over time.
PA Adaptive mode

Keeps the last gated microphone or one
Mic 1–8 on when no mics are providing a

.1 to 8.0 seconds
Programs the amount of time it takes
until the mic starts the off attenuation
