Mojo Squeeze
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.
The Rane Mojo Series maintains sonic and construction
quality not found (until now) in this price range. Designed for
the working musician or DJ…simple operation…reduced
features…without compromise in audio quality or dependability.

Architectural Specifications
The dynamic processor shall be a two (2) channel unit
with separate compression controls for each channel. A link
switch shall be provided to allow compression tracking
between channels. The compressor shall provide a means for
setting threshold and ratio independently. LED meters shall
be provided as an indication of gain reduction for each
channel. All attack and release characteristics provided by the
compressor shall be a function of the current program
material, thus providing a high level of transparency to the
listener. The unit shall include an automatic downward
expander circuit.
RFI filters shall be provided at the processor’s inputs.
Input level controls shall be provided for each channel. LEDs
shall be provided to indicate the presence of an input signal as
well as high level overload conditions. Bypass switches shall
be provided for each channel. The inputs shall be active
balanced/unbalanced designs terminated with XLR & ¼" TRS
connectors. The outputs shall consist of both an active
balanced XLR design and an active unbalanced ¼" TS design.
The unit shall be capable of operation by means of its own
built-in power supply connected to 120 VAC (230 VAC
where applicable) and meet UL, cUL, and CE requirements.
The unit shall be entirely constructed from cold-rolled steel,
and mount into a standard EIA relay rack occupying 1 rack
space.
The unit shall be a Rane Corporation Model MC 22.
