Limiter, and post-High-Pass. Useful for setting the channel gain.
(PFL) 2

M
Summed mono of the left and right output bus.
ST Stereo monitoring of the master output bus. This is the primary monitoring path.
RTN Stereo return from the RTN monitor input path.
M-MS
Monitoring of the mono signal of an MS stereo signal.
ST-MS
Monitoring of discrete MS signals in the headphones as a decoded stereo signal.
RTN-MS
Monitoring of discrete MS return signal in the headphones as decoded stereo signal.
Headphone Level and Overload LED
The Headphone Level controls the overall headphone level sent to the headphones. The adjacent
LED indicates that the headphone circuit is overloading. The LED will also illuminate with an
overloaded RTN signal.
Return Monitoring
Return input connector
Adjusts return input level
Indicated by the RTN positions on the rotary switch, audio sources connected to the mixers 3.5-mm
jack labeled RTN can be monitored in headphones. Return, or “confidence monitoring,” is useful
to monitor audio from a camera or recorder. Typically, a camera’s headphone output is used as the
Return Monitor source. Return levels are controlled by the heaphone level, while the return level
sensitivity can be adjusted with the RTN L and RTN R Trim controls.
