Function Switches
OverEasy®: Activates the OverEasy® compression function.
I/O Meter: Switches between monitoring input and output levels on the Input/Output Level meter.
Bypass: Activates the direct input-to-output hard-wire bypass.
Operating Level (rear panel): Switches the nominal operating level between -10 dBV and +4 dBu simultaneously for both input and output levels.
Stereo Couple: Couples channels in stereo pairs. Channels One and Three become the master channels.
