- Page 7 MBP Front-Panel Features Compressor Threshold This 31-detent potentiometer adjusts the level at which the compressor begins to attenuate the signal and is fully vari- able within a signal level range of +20dBu to -30 dBu. If the compressor input signal level exceeds the set threshold level, compression will occur.
- Page 8 MBP Front-Panel Features Gain This 31-detent potentiometer provides two different functions. When used with the compressor, the Gain control acts as standard Make-Up Gain, allowing the user to add gain to the compressed signal to match the bypassed signal level. When used in the context of the PIIMB limiter, the Gain control allows the user to set the desired “ceiling”...
- Page 9 MBP Front-Panel Features Limiter Limit This 31-detent potentiometer controls the threshold of the soft-clip limiter section. The limiter is disengaged until the user rotates the Limit potentiometer past the 3rd detent (+24dBu) from the fully clock-wise (OFF) position. As the user rotates the threshold control counter clock-wise, the limiter’s release time gradually increases.
- Page 10 MBP Front-Panel Features (continued) Silk This illuminated push-button switch toggles through the available SILK transformer harmonic saturation modes: OFF, RED, and BLUE. Red Silk has a high frequency emphasis associated with the transformer harmonics, while Blue Silk has a low frequency emphasis associated with the transformer harmonics. We encourage the user to experiment with both modes to find the most suitable tonal coloration for their particular application.
