General Description
The Rane MP 24x Mixer is a giant step forward for night
club mixers. Following the advice of the most renowned
figures in the night club market, Rane developed the MP 24x
to break down the limiting barriers of previous mixer designs.
Featuring four Stereo Input mixing Channels, each
supplied with a selection of several Phono and Line Inputs,
the MP 24x easily suits the needs of the most complex audio/
video installations. A total of six Stereo Line Inputs are
available plus three Stereo Phono Inputs.
The Mic Control section of the MP 24x handles two
microphones simultaneously. Both mics may be contoured by
the three-band Mic Equalizer as well as processed through a
Mic Loop jack. On the rear of the unit, an XLR low-Z Main
Mic Input with switchable Phantom Power, and a ¼" hi-Z
Aux Mic Input are both mixable.
The Output section of the MP 24x provides a Master
Level fader, four band Program Equalizer (independent of the
Microphone EQ), two auxiliary output controls (Zone and
Booth), a stereo 12-segment Peak Program Meter and full
Headphone Control monitoring and cueing system.
The rear of the MP 24x, besides holding all of the normal
Input and Output connectors, features a transformer isolated
Light Control Output with associated Level control, balanced
XLR Main Outputs, Program Equalizer EQ Range switch (±4
dB or ±8 dB) and a System Mono switch.
All sliders on the MP 24x are studio-quality, side wipe
faders as found on high quality audio mixing consoles.
New features have been added to the MP 24x. Active
Crossfader™ technology combines state of the art voltage
controlled amplifier design with a professional quality, dualrail Alps crossfader control. This combination sets new
standards for performance, reliability and serviceability.
Virtually all crossfader noise is eliminated. Channel to
channel crosstalk is greatly reduced and the off isolation of
the faded channel is greatly increased. Active Crossfader
technology dramatically increases the service life of the
crossfader. In the unlikely event of crossfader failure, there is
no loss of signal. If a crossfader becomes rough or noisy, it
may be “hot-swapped” during a performance with no interruption of the audio signal. Simply use the input faders to set
the audio levels while the crossfader is out of service.
Each of the Phono Inputs can be converted to Line Inputs
by moving internal jumpers. Another internal jumper allows
defeating the Booth Ducker circuit when the mic is activated—this feature has been requested by those wishing to
use the Booth Output as a second record output or second
zone. Another jumper allows the Mic section to be mixed to
the Tape Outs—the default setting is “music only”.

Application Information
Extreme care must be taken when installing the MP 24x.
So many pieces of equipment all connect to the MP 24x that if
proper interconnection wiring is not done, many problems
occur. Our technical service people spend the majority of
their MP 24x time in just unraveling improperly wired
systems. Everything from bad RCA cables (common) to
incorrectly grounded cables (very common) cause unnecessary complaints. Also, many units returned for noisy LOOP
related problems turn out to be problems with the unit
installed in the loop — not with the MP 24x.
Here are a few of the important user details of the MP 24x:
The Master Level control on the front goes to 10. But
what 10 means is determined by the Max Output Gain
Reduction control on the rear (out of the way of inquisitive
fingers). You limit the max gain, hence, the max output, using
this control. This allows the MP 24x to be operated at
compatible maximum levels for the system power amps.
Likewise, the Peak Program Meters are calibrated by the
rear mounted Meter Sensitivity Adjust control. Output levels
ranging from 0.6V to 10V may be set to indicate full scale on
the Meters. Once calibrated, this means when all LEDs are lit
you know the system is, in fact, at maximum level.
The labeling on the Program Equalizer control knobs
indicate Max or Min at their extremes. What this means is
again determined by a switch on the rear panel. You have two
choices: ±4 dB or ±8 dB. Both modest amounts. You determine what the system allows in the way of maximum added
EQ and set it. The operator is happy because they can rotate
the pots to their extremes, and you are happy because you
know this cannot destroy anything. Everybody wins with an
MP 24x.
