HPF IN: Push-button switch that illuminates GREEN when the 6dB/octave HPF is engaged.
LF: 31-detent potentiometer that controls the Low Frequency Shelf gain within a range of +/- 9dB.
LF FREQ: 31-detent potentiometer that controls the Low Frequency Shelf corner frequency within a range of 30Hz to 240Hz.
HF: 31-detent potentiometer that controls the High Frequency Shelf gain within a range of +/- 9dB.
HF FREQ: 31-detent potentiometer that controls the High Frequency Shelf corner frequency within a range of 3kHz to 24kHz.
EQ IN: Push-button switch that illuminates GREEN when the equalizer section is engaged.
THRESHOLD: 31-detent potentiometer that controls the compressor threshold within a range of +24dBu to 0dBu.
S/C HPF: 31-detent potentiometer that controls the corner frequency of the side-chain high-pass filter within a range of 20Hz to 350Hz.
COMP IN: Push-button switch that illuminates GREEN when the compressor section is engaged.
GAIN REDUCTION: LED that illuminates GREEN when gain reduction is occuring. The LED indicates compression for left and right channels.
RELEASE: 31-detent potentiometer that controls the Release time of the compressor within a range of 100mS to 1.5S.
RATIO: Opaque push-button switch that toggles between a LO (OUT) 2:1 ratio and a HI (IN) 5:1 compressor ratio curve.
BLEND: 31-detent potentiometer that controls the amount of dry (0%) vs. wet (100%) compressed signal in the audio path.
GAIN: 31-detent potentiometer that controls the amount of compressor make-up gain within a range of 0dB to +20dB.
WIDTH IN: Push-button switch that illuminates GREEN when the WIDTH section is engaged.
WIDTH HPF: 31-detent potentiometer that controls the corner frequency of the width processing HPF within a range of 50Hz to 800Hz.
WIDTH: 31-detent potentiometer that controls the amount of Width stereo field processing within a range of MIN to MAX.
SILK IN: Push-button switch that illuminates PURPLE when the SUPER SILK section is engaged.
BLUE: 31-detent potentiometer that controls the amount of low frequency SILK pre-emphasis.
DRIVE: LED that illuminates RED when the signal level reaches the optimal range for transformer harmonics. The LED indicates drive level for left and right channels.
RED: 31-detent potentiometer that controls the amount of high frequency SILK pre-emphasis.
HARMONICS: 31-detent potentiometer that controls the amount of transformer harmonics added to the audio path.
ZENER DRIVE: Push-button switch that illuminates AMBER when the soft clip circuitry is engaged.
BYPASS ALL: Push-button switch that illuminates RED when the master bypass is engaged. This master bypass is a true hard- wire bypass that ensures the MBT will pass audio in the event that power is lost.
OUTPUT TRIM: 31-detent potentiometer that controls the amount of output trim within a range of +/- 12dB.
OUTPUT METERS: Stereo 16-segment LED meters that indicate output level in dBu.
