D-901 Mic Bus
The Mic Bus allows each channel to be sent at
various levels to a side-chain processor, which
may be assigned independently of the main output
buses. Mic input signals may be processed
through this bus, adding Echo Effects and
Feedback Suppressor processing (dynamic/static
filtering), then mixed back into the main output
buses
