IMPORTANT INFORMATION...
Please read this entire manual before
connecting the DM2002X to your system.
For optimum performance:
SYSTEM PRECAUTIONS
• Use appropriate cables throughout your system:
Quality shielded audio cables and terminated
shielded video cables, low-capacitance preferred.
Speaker cables must be 14-gauge minimum; 12- or
10-gauge is better.
• Always make sure that AC power is OFF while
making any connections.
• Do not use excessively long cables (i.e. over
50ft/14m) Be sure plugs and jacks are tightly
mated. Loose connections can cause hum, noise or
intermittents that could easily damage your
speakers.
• Reliability will be enhanced through the use of
banana connectors on the speaker wires. Observe
correct speaker wire polarity. If in doubt, consult
your Numark dealer or a qualified technician.
• Never use spray cleaners on the slide controls.
Residues cause excessive dirt build-up and this
will void your warranty. In normal use slide controls
can last for many years. If they malfunction (usually
because of a dirty or dusty environment) consult a
professional technician.
• Take care to connect only one cable at a time. Pay
attention to the color-coded, labelled Input and
Output jacks.
• ALWAYS remember: “TURN AMPS ON LAST
AND OFF FIRST”. Begin with master faders or
volume controls on minimum and the amplifier
gain/input control(s) down. Wait 8 to 10 seconds
before turning up the volume. This prevents
transients which may cause severe speaker
damage.
• Never attempt to make any adjustments or repairs
other than those described in this manual. Take the
DM2002X to your dealer or to an authorized
Numark Service Center.
• Use restraint when operating controls. Try to
move them slowly. Rapid adjustments could
damage speakers due to amplifier clipping.
A NOTE ON CABLES:
• Avoid amplifier “clipping” at all costs: this
occurs when the red LEDs (usually on the front
panel of most professional power amplifiers) start
flashing. “Clipping” is when the power amplifier is
distorting and working beyond it’s limits. Amplifier
distortion is THE major cause of speaker failure.
Make the input and output
connections with readily available
low-capacitance stereo cables.
Quality cable makes a big difference
in audio fidelity and punch. See your
Numark dealer or an electronics or
audio specialist store if you are not
sure which cables to get.
• To prevent fire or shock hazard, do not expose
the unit to rain or moisture. Never place cans of
beer, soda, glasses of water or anything wet
on top of the mixer!

If the DM2002X is your first mixer, please read this
entire manual before you begin operation. If you are an
experienced DJ we recommend reading the manual so
you may fully appreciate this newer technology. The
DM2002X can be 10” rack-mounted or used as a free-
standing unit. Keep in mind that there are a few features
you may never have seen before in a mixer of this type
that you will need to read about.

INSTALLATION AND OPERATION
1
Study the Connections Diagram on page 13. First,
connect all stereo input sources. Next connect your
microphone(s) and monitor headphones. Make sure all
faders are at "zero" and the unit is off. Finally, connect
the stereo outputs to the power amplifier(s) and/or
audio sources. Plug the DM2002X into AC power.
Now you are ready to switch it on.

CHANNEL FEATURES

1. Channels 1, 2, & 3 Rotatable Input Toggle
Switches select which source will be live to that
channel based on what you have connected to the rear
panel input section.
1 5
1 6
To rotate or replace the toggle
a. Turn off all power!
b. Remove corner screws
c. To rotate lift of toggle and place in it’s new
position or to replace unplug the old unit and
plug in the new one.
4. Send Buttons are for allowing a channels pre-fader
output to be sent to the send connectors in the rear of
the unit. These are used for sampling and other special
effects. You would return the send signal through
another input channel.
d. Screw toggle back into place.
5. Treble, Middle, and Bass Controls are for
setting appropriate equalized levels for the music you
are playing. When turn all the way left they “CUT” the
signal by -30dB for special effects mixing.
2. The Input Faders are low-noise, low-impedance,
high-quality, smooth Alps™ faders. These control
individual source levels in the mix.
6. Gain Controls are for accurately matching audio
levels of the channels.
3. PFL and Channel Cue Assign. The PFL
pushbuttons are used to route channel audio to the
main volume meter and the Cue Monitor Section.
7. KILL buttons are for instantly eliminating the chosen
frequency area. This way you can mix the bass of one
song with the treble and middle of another.
When a PFL is pressed the main volume meter
changes its display to the PFL channel. This allows the
DJ to accurately match levels before mixing with that
channel’s gain control. The idea is to properly match
inputs, not the input with the output!

CROSSFADER SECTION
14. Stereo Output Level Indicator. This fast,
accurate stereo meter tracks the output level. It's OK to
be occasionally "in the red" as long as +5dB or +8dB
aren't constantly lit. Set the crossover, equalizer and
power amp inputs to avoid distortion at each step in the
audio chain. Proper attention to the meter results in the
punchiest possible sound without audible distortion.
8. The Replaceable Crossfader achieves clean
segues between the two selected input channels.
"Hard left" selects Channel 2. "Hard right" selects the
Channel 3. With the crossfader centered both channels
are live. Use the crossfader for fast and seamless
segues from one selected channel to the other.
This meter is also used to monitor the PFL/CUE section.
When a PFL LED is lit the display indicates this
channel, when the MASTER LED is lit then the
Master output is shown.
Note: The crossfader is user replaceable in
case of failure. Simply unscrew the two large
screws which hold it in place, lift it out and
disconnect it’s cable. Re-attach the new
crossfader and screw the mounting plate back
onto the unit - you’re back in business!
CUE SECTION
15. The CUE section includes the Program Mix
(PGM) control, the Headphone Volume control
and the Headphone Connector located on the
front of the unit. Connect headphones with a standard
1/4" stereo plug. The PFL audio is sent to the
headphone amp using the PFL Assign
9. The Crossfader Control toggle allows the DJ
either reverse the direction of the crossfader or turn it
off. By reversing direction Channel 3 will be on the left
and Channel 2 will be on the right.
10. Transform Buttons are for quickly reversing the
crossfader direction in order to create various special
effects.
Pushbutton and the PGM Mix control. The
Program Mix controls the amount of program audio in
the headphones so that beats can be matched exactly
and segues are smooth when a song is cued.
11. Beat indicator lights show peaks in the music
that usually represent a strong drum beat. You can use
these to help you try and match up beat mixes.
MIC SECTION
16. The MIC Connector is located on the front panel
of the unit and is controlled through an input on
Channel 1.
MASTER/BOOTH OUTPUT SECTION
12. The Stereo Master Fader controls the overall
output level.
13. The Booth Level controls speaker volume for a
remote zone or booth monitors. If you do not use booth
monitors the output can feed a tape deck, another
amplifier, another mixer or a satellite speaker system.
Note: This can also be used to supply line level audio
to a lighting controller or to lights that are sound
activated.
17. 12V BNC Connector allows a 12 volt gooseneck
lamp to be connected directly to the mixer. This light is
readily available from your Numark dealer.
18. Power Switch and Power-On LED.
CONTRACTOR'S NOTE: Booth Level provides
zone control in installations where there are two
separate rooms, or a bar and dance floor, for example.
Remote zone volume should be controlled from the
DM2002X.

REAR PANEL: INPUTS AND OUTPUTS
6. Channels 2 and 3 Line Inputs are unbalanced
RCA jacks. The Line Input is selected with the toggle
switch on the front panel.
1. AC Connection. Plug your power cord in here.
See safety precautions on page 3 for proper treatment
of the power cord.
You can connect stereo audio from HiFi VCRs, cassette
and reel-to-reel tape decks, DAT machines, CD players,
laser discs, tuners, even synthesizers or other mixing
consoles.
2. GND is the grounding lug for all turntables. Always
use this connection (your turntable cable should have a
grounding wire).
NOTE: Plug mono audio sources into both Left and
Right inputs using a “Y” cable connector.
3. The Stereo Main Outputs are low-impedance
RCA connectors controlled by the Master fader.
7. Phono Inputs on Channels 1, 2 and 3 use
unbalanced RCA jacks. Your input signal is fed directly
to the DM2002X's high-quality RIAA phono pre-
amplifiers so use this position only for moving magnet
cartridges. Line level sources will overload the sensitive
phono pre-amps and will sound very bad, so always be
sure to toggle the line/phono switch over to line before
connection of line sources.
4. The Stereo Booth/Zone Outputs are low-
impedance unbalanced RCA jacks controlled by the
Zone Level control.
5. Send Output is set by the send buttons pressed
on the front panel. Hook up you sampler or other
processor here.
8. Line/Phono Input switch. Use this to allow line
level equipment to be plugged into your phono inputs
giving you a total of 5 line input options.
Warning: make sure the LINE/PHONO input
switch is set to line before playing any line
input level devices through your mix
