- Drive and level-match the interstage transformers with the I/O amplifiers

MBT Front Panel Controls
Input Level:
LED indication that illuminates GREEN when the input signal reaches -20dBu and illuminates RED to show when the input signal reaches +23dBu. This indication is post input trim control.
Input Trim:
31-detent potentiometer that controls the input level within a range of +/- 12dB.
HPF Freq:
31-detent potentiometer that controls the HPF frequency within a range of 15Hz to 100Hz.
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 S/C HPF 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 simultaneously.
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.
Power:
LED that illuminates GREEN when POWER is ON.
MBT Rear Panel
Power:
IEC standard 3 pin grounded switched AC power inlet with an input range of 100-240 VAC, 50/60Hz. 70 Watts maximum AC power consumption.
GND Lift:
Slide switch that lifts XLR Output Pin 1 from chassis ground to minimize ground loops.
Output:
Balanced XLR outputs with custom Rupert Neve Designs transformers capable of handling up to +25.5dBu at 1kHz.
Input:
Balanced XLR combo jack inputs capable of handling up to +26.8dBu at 1kHz.
