Function Swithces
SC EXTERN: switches the detector section to the external SC input

SC MON: monitoring the external SC input, disengaging the normal audio

INTERACTIVE: enables the Interactive Knee Adaption characteristics

CONTOUR: allows for frequency dependent detection

AUTO: enables the automatic and program dependent setting of the Attack-/Release times, disengaging the manual Attack-/Release controls

I/O METER: switches between input and output for the level meter

IN/OUT: relay controlled hard-bypass

OPERATING LEVEL: changes the internal reference level from +4 dBu to -10 dBV

COUPLE: linking both channels for stereo operation and channel 1 becomes master
