Function Switches
SC Ext: Routes the external sidechain input signal to the detector.
SC Mon: Routes the sidechain signal to the output, interrupting the normal audio.
OverEasy: Activates the OverEasy compression function.
Contour: Activates the frequency-dependent detector function.
Auto: Activates automatic program-dependent attack and release times, disabling the manual Attack and Release controls.
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 relay bypass. Relay automatically hard-wire bypasses unit at power-down and provides a power-on delay of 1.5 sec.
Operating Level (rear panel): Switches the nominal operating level between -10 dBV and +4 dBu simultaneously for both input and output levels.
ST Link: Links both channels for stereo operation. Channel One becomes the master.

Indicators
Gain Reduction Meter: 12-segment LED bar graph at 1, 2, 4, 6, 9, 12, 15, 18, 21, 24, 27, and 30 dB
Input/Output Meter: 8-segment LED bar graph at -24, -18, -12, -6, 0, +6, +12, and +18 dBu
Compressor Threshold Meter: 3-segment LED bar graph at Below (-), OverEasy, and Above (+)
Exp/Gate Threshold Meter: 2-segment LED bar graph at Below (-) and Above (+)
Limiter, Threshold Meter: 1 LED to indicate PeakStopPlus limiting
Function Switches: LED indicator for each front-panel switch
