Monitor Output Gain Bypass
By default, monitor output levels are continuously variable. However, the monitor 
outputs can be set to completely bypass the monitor level circuitry and operate at a 
fixed reference level. This feature is set with the MONITOR OUTPUT GAIN menu in the 
Hardware panel within the Console Settings window. 
Tip: This feature routes the signal directly from the D/A converters to the monitor 
outputs for the purest signal path when level control is not needed (for example, 
when connecting the monitor outputs to an external monitor controller).
When the MONITOR OUTPUT GAIN menu is set to BYPASS in Console Settings:
•  The Monitor Level Indicator ring (#23) is solid green
•  When the Monitor knob (#22) is rotated, the ring flashes to indicate that no level 
adjustment is occurring
•  ALT monitoring and assignable FCN switch features are unavailable
•  Signals at the Monitor Outputs (#34) are output at line level (without attenuation)
Monitor Mute
Pressing the Monitor knob toggles the mute state of the signals at the Left & Right 
Monitor Outputs on the rear panel. If ALT monitoring is configured in the Hardware panel 
within the Console Settings window (when ALT COUNT is a non-zero value), the ALT 
monitor outputs are also muted by this control.
When the monitor outs are muted, the Monitor Level Indicator ring (#23) is red.
Note: Monitor Mute does not mute the headphone outputs.
