General Description

Finally! A cure for confusion has arrived. Quit guessing and anguishing over proper compressor settings. Get on with what’s important, your work! Rane has created a compressor that offers noise reduction and simple settings. No more compression headache! The MC 22 Mojo Squeeze is just what the doctor ordered. Use only as directed.

Let’s start with what a compressor actually does. No matter how you cut it, this is an automatic volume control. It is a hand on a knob, turning the volume down and turning it up again. The hand is really quick and really accurate, but it’s just turning a volume control.

When the input signal reaches a level set by the Threshold control, the compressor begins turning down the signal by an amount determined by the Ratio control. The MC 22, like most compressors, operates by making the loud signals quieter, but does not make the quiet parts louder. However, by keeping the loud signals under control, the entire system may be turned up when necessary to make the quiet parts louder.

There's more than just a stereo compressor working here. The adx circuit is an automatic downward expander, acting like a compressor running in reverse, making the quiet parts quieter. This is valuable in reducing system background noise. This is set at a Ratio of 2:1 that is only active when the input level drops below -55 dBu. The adx LED illuminates when the downward expander is active.

When using the MC 22 as a true stereo processor with left and right signals, activate the Link switch to prevent large balance and image shifts. While Linked, both Channels attenuate by exactly the same amount when either Compressor works, maintaining correct stereo imaging. The channels are totally independent with the Link switch off.
