MSCL is a stereo compressor in 4 hp designed for your master bus to help "glue" your mix together. Inspired by the DBX "Over Easy" style compressor, it features independent attack and release knobs, output gain, and an all-in-one knob function for compression which decreases threshold, increases gain and ratio all with one turn. Limit Switch allows the MSCL to act more like a peak limiter. The threshold switch lets you compress signals of different amplitudes. It also features a side chain input for classic ducking sounds on stereo tracks. Stereo Compressor in 4 HPSidechain input for classic ducking soundsEasy and intuitive designThreshold switch lets you compress modular level signals as well as lower level sourcesLimit switch limits the makeup gain on the comp knob to make compressor act more like a peak limiterCONTROLS Comp knob: adjusts makeup gain, threshold, ratio simultaneously. - 1.25:1 to infinite:1 ratio Attack Knob: Controls how fast the compressor will react to incoming transients Attack speed: 0.15ms/dB to 0.1s/dB Release Knob: Controls the speed in which the compressor will release. Release speed: 0.6ms/dB to 4s/dB Gain Knob: Adds up to +-35dB on the output Threshold Switch: Changes the threshold rainge Three ranges: -15dBu, -4dBu, +5dBu Limit Switch: Limits the comp knob's makeup gain. Makes the MSCL operate more as a peak limiter. Three selections: None, 9dB, 3dB Other Notable Things Depth: 38mm. Current Draw: +-50mA. Size: 4HP.
