QUICK START
If you won’t read the manual (we know how it is) here are a few basic “plug it in and get signal thru it” facts. e MP 22z has all
unbalanced RCA connectors, except for the XLR & ¼" Mic Inputs, ¼" Mic Loop, and the balanced ¼" TRS Master Outputs. Be
sure your amplifier is off while making connections. On the front panel, set all controls to the middle of their travel. Set all pushbut-
tons to their out position, slide the MASTER LEVEL all the way down. Turn the INPUT SELECT switch for Channel A or B to an
Input with material playing. Turn your amplifier on. Now slowly turn up the MASTER LEVEL and see the material on the meters
and hear it from the MASTER OUTPUT jacks.
ere are two places where you can get lost. If you bring a phono signal into PH/LN 1 or 2 be sure to keep the LINE/PHONO
switch set to PHONO; likewise when using a CD player be sure this switch is set to LINE. If you plug into the MASTER LOOP
RETURN the signal path thru the unit is broken, since these are switching jacks. ey are looking for the return from an outside
device that got its signal from the MASTER LOOP SEND, so only use these when you can make a complete loop.
With the CROSSFADER CONTOUR set to full counter-clockwise position, it operates as a typical constant-power 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?
WEAR PART
is product contains the following wear part subject to the
ninety (90) day warranty period described on page Warranty-1:
(1) Active Crossfader Assembly F 60.
Never connect anything except a Rane RS 1 to the thing
that looks like a red telephone jack on the rear of the
MP 22z. is is an AC supply and requires some special atten-
tion 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.

FRONT PANEL DESCRIPTION
1 Front panel MAIN MIC input: Use this XLR connector for connecting a balanced microphone of any impedance.
2 MIC EQ controls: Adjust the frequency contour of both Microphone Inputs. ey have no effect on any other Inputs. Position-
ing these controls to the “12 o'clock” position turns the Mic EQ off.
3 CHANNEL A & B EQ ENGAGE switches: Engaging this switch enables the Channel Equalizer to function. In the out posi-
tion, the Equalizer is bypassed.
4 CHANNEL A & B EQ level controls: ese four rotary controls, when enabled with the EQ ENGAGE switch, are used to
contour the frequency response of the selected Input Channel. is is not designed to be the only Equalizer in the system, this is
intended to provide EQ between varying program materials. We recommend an external graphic equalizer for best overall system
sound, connected between the MASTER OUTPUTS and the amplifier.
5 CUE A or CUE B switches: Engaging any single or combination of CUE pushbuttons sends any program present at the respec-
tive Channel's INPUT SELECT selector to the Headphone and meter cue sections. e yellow LEDs adjacent to each CUE
select button illuminate when the switch is engaged. Not recommended for beat sync lights. See Operating Instructions on page
Manual-6.
6 INPUT SELECT A & B: ese four position rotary switches provide Input selection between the various phono/line inputs for
their respective mixing Channels.
7 AUX LEVEL control: Adjusts the input Level from the AUX LINE IN jacks.
8 ZONE LEVEL controls: Adjust the output Levels of ZONE 1 and ZONE 2.
9 PEAK dBu CUE/PROGRAM meter: Can switch between two display modes. See 0 below.
0 Meter CUE/PROGRAM switch: In the out position, the meter indicates Master Program output level in PEAK dBu in LEFT
and RIGHT stereo. In the in position, mono CUE level is displayed on the LEFT side and mono Program level is displayed on
the RIGHT side.
q REMOTE MIC ENGAGE switch: When pressed, ENGAGES the REMOTE MIC Input. e adjacent red LED flashes when-
ever the switch is pressed in, signalling that the Main Mic is on.

w MAIN & REMOTE MIC OVERLOAD indicator: Monitors both Microphone Inputs, before and after the MIC EQ. It lights
whenever these levels exceed 4 dB below clipping. Occasional flickering is normal; however, it should not be allowed to light steadily.
e MAIN MIC ENGAGE switch: When pressed, ENGAGES the MAIN MIC Input. e adjacent red LED flashes whenever the
switch is pressed in, signalling that the Main Mic is on.
r MAIN MIC LEVEL control: Adjusts the Level of the front panel MAIN MIC Input.
t REMOTE MIC LEVEL control: Adjusts the Level of the rear panel REMOTE MIC Input.
y 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 performance cut and scratch effects. See Figure 1 on page Manual-1.
u A & B Input Channel faders: Control the Levels of the Input selected on each Channel.
i ACTIVE CROSSFADER: Controls the relative level of the Inputs assigned to the A and B Channels. When this fader is at its far
left, only Channel A is heard from the Outputs. As the fader is moved toward the right, the volume of Channel B is increased.
When the fader is centered, both Channels deliver equal volume. As you might expect, at the far right only Channel B is heard
from the Outputs. In the unlikely event of Crossfader trouble, See Replacing the Active Crossfader below. See Figure 1 on page
Manual-1 for response curves of various contour settings.
o MASTER LEVEL fader: Determines the final Level at the MASTER and ZONE OUTPUTS. Unity gain is around “6”.
p HEADPHONE PAN control: Serves two purposes. When the Headphone Mode switch (see s) is in STEREO mode, this con-
trols the relative levels of the Cue and Program mixed together in Stereo. When the Mode is switched to MONO, this controls
the balance between Mono Cue in the left earcup and the Mono Program in the right.
a HEADPHONE LEVEL control: Clockwise rotation of this rotary control increases the Headphone drive Level.
s HEADPHONE mode switch: In the out position, this switch feeds Stereo Cue and Program to both earcups. In the in position
the headphone circuit provides Mono Cue to the Left ear and Mono Program to the Right ear.
d HEADPHONE Output jack: A ¼" tip-ring-sleeve stereo jack delivers signal to stereo headphones.
f POWER “ON” indicator: Illuminates when the MP 22z is connected to an appropriate power source (see Rear Panel r).
FADER CLEANING
With heavy use in harsh environments, the faders may need
lubrication. is treatment extends longevity and can make used
faders as good as new. e fader assembly must be removed from
the MP 22z for proper cleaning. We recommend any of the fol-
lowing cleaning solutions:
Caig Cailube MCL 100% spray lubricant
Caig Cailube MCL 5% spray cleaner
CRC 2-26 (www.crcindustries.com)
Order CaiLube MCL® from:

REPLACING THE ACTIVE CROSSFADER
e Crossfader may be removed without any disassembly of
the MP 22z itself, and may be performed while the unit is oper-
ating with no interruption of the audio signal.
F 60 and F 45 Fader Kits are available from your local retailer
or the factory. e kit includes full assembly including knobs,
ribbon, and face plate.
1. Remove the two (2) outer screws attaching the crossfader as-
sembly 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 replacement
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.

Manual-4
REAR PANEL DESCRIPTION
1 REMOTE MIC/LINE INPUT: is ¼" tip-sleeve Input is for wireless mics or other high-impedence sources.
2 MICROPHONE LOOP jacks: ese ¼" tip-sleeve connectors are for inserting external signal processing in the microphone
circuit only. ese jacks do not effect the other Inputs.
3 PHONO GROUND screw: is can facilitate your hum chasing, buzz eliminating experiments, providing a place to connect
those extra wires coming out of the turntables. See Chassis Grounding, next page.
4 PHONO/LINE 1 & 2 INPUTS: ese stereo Inputs are switchable from a PHONO (RIAA) stage for magnetic cartridges to a
LINE level Input suitable for any line level device such as a CD player. Each Input may be adjusted with its TRIM control for
level matching purposes if desired.
5 LINE 3, 4, 5 & 6 INPUTS: ese stereo pairs of RCAs connect LINE level Inputs only. Each Input may be adjusted with its
TRIM control for level matching purposes if desired.
6 MASTER LOOP SEND & RETURN: ese stereo pairs of RCA connectors allow inserting external signal processing in the
Master, Zone and Headphone circuits. is feature does not affect the operation of the MIC or AUX INPUTS. ese are switch-
ing jacks—always finish the loop when connecting send or return. Only connect to a device that is capable of returning signal
back to the MP 22z.
7 AUX LINE INPUT: is stereo pair of RCA connectors is an extra set of LINE level Inputs with an independent front panel
LEVEL control (see Front Panel, 7).
8 TAPE OUTPUT: ese line level RCA Outputs are intended for use with a tape recorder, but not necessarily restricted to that
purpose. You may be creative. ese Outputs are not affected by the MASTER LEVEL fader.
9 MIC & AUX TO TAPE OUT switch: In the YES position the Mic and Aux signals along with all Inputs are routed to the TAPE
OUTPUT. In the NO position only program material from Inputs 1 through 6 appear at the TAPE OUTPUT.
0 MIC & AUX TO ZONE 1 switch: In the YES position the Mic and Aux signals along with all Inputs are routed to the ZONE 1
OUTPUT. In the NO position only program material from Inputs 1 through 6 appear at the ZONE 1 OUTPUT. Note: Mic and
Aux signals are never routed to the ZONE 2 OUTPUT.
q ZONE OUTPUTS: ese are stereo pairs of line level RCA Outputs with independent front panel OUTPUT LEVEL controls
(see Front Panel, 8) and are not affected by the MASTER LEVEL control.
w MASTER OUTPUTS: ese balanced ¼" TRS (tip-ring-sleeve) Outputs connect to a balanced equalizer or amplifier. ough
not recommended, unbalanced ¼" TS (tip-sleeve) cables may be used for short runs (under 3 meters [10 feet]) to an amplifier
with unbalanced inputs. See RaneNote 110 “Sound System Interconnection” for wiring recommendations.
e Chassis ground point: is screw is provided for connection to chassis ground if required. See Chassis Grounding on the next
page.
r POWER input connector: is is not a telephone jack! Connect an 18 volt AC center-tapped transformer only. Use only a Rane
model RS 1, shipped with the unit, or other RS 1 compatible power supply approved by Rane.

MP 22z CONNECTION
When first connecting the MP 22z to other components,
leave the power supply for last. is gives you a chance to make
mistakes and correct them without damaging your fragile speak-
ers, ears and nerves.
All of the line level inputs are unbalanced RCA connec-
tors. Inputs PH/LN1, LINE 3, LINE 4 and LINE 5 appear on
Channel A; while PH/LN2, LINE 4, LINE 5 and LINE 6 each
appear on Channel B. e only restriction is the assignment of
the Phono Inputs, one per Channel A and Channel B. So for you
phono only users, Inputs are pretty simple; Phono 1 is on Chan-
nel A and Phono 2 is on Channel B. If you bring a phono signal
into PH/LN 1 or 2 be sure to set the appropriate Line/Phono
switch to PHONO. Like a mic input, a phono requires a lot of
gain plus RIAA equalization.
e Aux Line Input has its own Level control on the front
panel and sums with the other signals before the Master and
Zone Level controls.
e Main Mic Input on the front panel allows use of a goose-
neck mounted microphone. e connector is rotated such that
a right angle connector may be used when connecting via mic
cable. e Remote Mic Input is located on the rear panel and has
enough range on it's Level control to accommodate mic or line
level inputs. e Mic Loop has an unbalanced ¼" TS (Tip/
Sleeve) Output (send) and a separate ¼" TS (Tip/Sleeve) Input
(return). e effect in this Loop affects both Mics simultaneously.
Inserting plugs into the Master Loop Return breaks the
signal path thru the unit unless they contain the return from an
outside device that got its signal from the Master Loop Send. In
other words, these are switching jacks—only use a stereo effects
device that passes signal completely patched through.
e Mic and Aux can be switched to appear or not appear
on the Zone 1 Output, and the Mic and Aux can be switched
to appear or not appear on the Tape Output, determined by the
YES/NO switches on the rear panel.
If you are connecting balanced devices (3-conductor) to
either the Input or Output of the MP 22z, consult the included
RaneNote “Sound System Interconnection” for proper wiring
procedures.
IMPORTANT NOTE
CHASSIS GROUNDING
If your system exhibits excessive hum or buzzing, there is an
incompatibility in the grounding configuration between units
somewhere. Your mission, should you accept it, is to discover
how your particular system wants to be grounded. Here are some
things to try:
1. Try combinations of lifting grounds on units that are sup-
plied with ground lift switches or links.
2. If your equipment is in a rack, verify that all chassis are
tied to a good earth ground, either through the line cord ground-
ing pin or the rack screws to another grounded chassis like the
amplifier.
3. Units with outboard power supplies do not ground the
chassis through the line cord. Make sure that these units are
grounded either to another chassis which is earth grounded, or
directly to a known ground by means of a wire connected to
a screw on the chassis with a star washer to guarantee proper
contact.
Please refer to the RaneNote “Sound System Interconnection”
included with this manual for further information on system
grounding.
