Rane MM 8z User Manual
OPERATORS MANUAL MM 8z
MOJO CLUB MIXER
QUICK START
Here are a few basic “plug and play” steps to get you performing. If you are a first-time DJ mixer user, please do
yourself a favor and at least read this section.
Begin by making sure your amplifier is off before making connections. The MM 8z has all unbalanced connectors,
except for the ¼" balanced Main Outputs and XLR Mic Inputs. Plug a source component, such as a CD player, into one of
the four LINE Inputs on the rear. Connect the MAIN OUTPUTS to your amplifier. Set all front panel controls to the
middle of their travel and all pushbuttons to their out position. Slide the MASTER LEVEL down to 0. Set the INPUT
SELECT switch to your active Source Input. Plug in the MM 8z’s power supply and see the PWR indicator illuminate.
Turn on your source and amplifier. Slowly turn up the MASTER LEVEL, as the meters light and music is heard from the
speakers.
You can get tripped up at two places. If you have a phono signal into one of the four PH/LN Inputs, be sure the PH/LN
switch is in the PHONO position (in); likewise, when using a tape deck or CD into these Inputs, be sure the switch is in the
LINE (out) position. If you plug into the PROGRAM LOOP, the internal signal path is broken. Be sure that a complete
loop is made, to and from an outside device.
Couldn’t be easier, right?
With the CROSSFADER CONTOUR set to full
counter-clockwise position, it operates as a typical constantpower crossfader. Set to clockwise position, the crossfader
has the very steep slope as indicated in Figure 1 to the right.
Now that was a pretty quick start, right?
Never connect anything except a Rane RS 1 to the
thing that looks like a red telephone jack on the rear of the
MM 8z. This is an AC supply and requires some special
attention if you do not have an operational power supply
exactly like the one that came with your unit. Consult the
Rane factory for a replacement or substitution.

Manual-1
FRONT PANEL DESCRIPTION
MAIN MIC ON switch: puts the Main Mic signal into the mixer signal path. When the switch is pressed in, the Main Mic
is on and the adjacent red indicator blinks.
Front panel MAIN MIC input: accepts a balanced microphone with an XLR connector. A parallel Main Mic Input is on the
rear of the unit. Do not connect microphones to both front and rear Main Mic inputs.
MAIN MIC LEVEL control: adjusts the level of the Main Mic Input.
MIC OVERLOAD indicator: monitors both Main and Aux Mic Inputs, before and after the Mic EQ. It lights when the
signal exceeds the Mic section’s output capability (3 dB below clipping). Occasional flickering is acceptable; however,
steady lighting requires a reduction in the Mic LEVEL control to prevent distortion.
AUX MIC ON switch: puts the Aux Mic signal into the mixer signal path. The adjacent red indicator blinks when the
switch is pressed in, indicating that the Aux Mic is on.
AUX MIC LEVEL control: adjusts the level of the Aux Mic Input.
MIC EQ controls: contour the frequency response of the summed Main and Aux Mic Inputs.
Source Input Select switch: selects either a Phono/Line or Line Input for the Source. In the center position the Source
Input is muted.
Source EQ controls: contour the frequency response of the selected Input.
Source Input fader: controls the level of the selected Input.
Source ASSIGN PRE/POST CROSSFADER switches: are provided for Inputs 1 and 4. In the PRE (up) position, this
Input is routed to the Crossfader. In the POST (down) position the Input bypasses the Crossfader.
ACTIVE CROSSFADER: controls the relative output level from the summed A and B Mixes. When the fader is at its far
left, only the A Mix is heard from the Outputs. As the fader is moved toward the right, the amount of B Mix is increased and
the amount of A Mix is decreased. When the fader is centered, equal amounts of A and B Mixes are routed to the Outputs.
Fully right is all B Mix at the Outputs.
Manual-2
CROSSFADER CONTOUR control: Allows adjusting the “shape” of the Crossfader response from a gentle curve for
smooth, long running fades, to the steep pitch required for top performance cut and scratch effects. See Figure 1 on page
Manual-1.
Meter and Mode switch: This peak-dBu reading meter displays one of two modes, depending on the switch position. In the
LEFT/RIGHT (out) position, the meter indicates the stereo level in the LEFT and RIGHT Main Outputs. In the CUE/PRG
(in) position, mono CUE level is displayed on the Left meter and mono PROGRAM level is displayed on the Right meter.
MASTER LEVEL fader: adjusts the level at the rear panel Main Outputs.
AUX INPUT: This stereo pair of RCA connectors is an extra line level Input which sums with the other signals before the
Master Level fader.
AUX IN LEVEL control: adjusts the level of the front panel Aux Inputs.
AUX OUTPUT: This stereo pair of RCA connectors provides an extra line level output mix. This is the same signal as the
Main Outputs, but with a separate Level control.
AUX OUT LEVEL control: adjusts the level of the front panel Aux Outputs. This control is independent of the Master
Level fader and Main Outputs.
CUE switches: Pressing in any or all of the CUE pushbuttons routes the respective Source to the Headphone and Meter Cue
sections. The adjacent yellow indicator illuminates when the switch is depressed.
HEADPHONE PAN control: adjusts the relative levels of Cue and Master signals mixed together in stereo for the head-
phones. Counterclockwise rotation increases the amount of Cue signal; clockwise rotation increases the amount of Master
signal.
HEADPHONE LEVEL control: adjusts the volume for the headphones.
HEADPHONE Output jack: This stereo ¼" TRS (Tip-Ring-Sleeve) jack accepts ¼" TRS stereo headphone plugs (do not
use mono plugs).
POWER “ON” indicator: When the yellow indicator is lit, the MM 8z is ready to go.
Fader Cleaning
With heavy use in harsh environments, the faders may
need lubrication. This treatment extends longevity and can
make used faders as good as new. The fader assembly must
be removed from the MM 8z for proper cleaning. We recommend any of the following cleaning solutions:
Caig Cailube MCL 100% spray lubricant
Caig Cailube MCL 5% spray cleaner
CRC 2-26 (www.crcindustries.com)
Order CaiLube MCL® from:
CAIG Laboratories, Inc.

REPLACING THE ACTIVE CROSSFADER
The Crossfader may be removed without any disassembly
of the MM 8z itself, and may be performed while the unit is
operating with no interruption of the audio signal.
F 60 and F 45 Fader Kits are available from your local
retailer or the factory. The kit includes full assembly including knobs, ribbon, and face plate.
1. Remove the two (2) outer screws attaching the crossfader
assembly to the front panel.
2. Pull the Crossfader Assembly forward and unplug the
ribbon from the connector on the bottom board.
3. Proceed with Cleaning Instructions, or install the replace-
ment assembly by reversing the above instructions.
CLEANING INSTRUCTIONS
1. Hold the fader assembly away from the mixer.
2. Position the fader at mid-travel.
3. Spray cleaner/lubricant into both ends of the fader.
4. Move the fader over its full travel back and forth a few times.
5. Shake excess fluid from the fader assembly.
6. Wipe off excess fluid.
