IMPORTANT INFORMATION...  
Please read this entire manual before  
connecting the mixer 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  
unit 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!

GUIDED TOUR OF FEATURES AND OPERATING INSTRUCTIONS...  
If this is your first mixer, please read this entire manual  
before you begin operation. If you are an experienced  
DJ we highly recommend reading the manual so you  
1 7  
may fully appreciate this newer technology. This mixer  
can be 10” rack-mounted or used as a free-standing  
unit. Keep in mind that there are a few features you may

1 6  
never have seen before in a mixer of this type that you  
will need to read about.

INSTALLATION AND OPERATION  
1 1

1 3

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 mixer into AC power. Now you  
are ready to switch it on.

CHANNEL FEATURES  
1. Channel Input Toggle Switches select which  
source will be active on that channel based on what you  
have connected to the rear panel input section.  
1 0  
1 4

2. The Input Faders are low-noise, low-impedance,  
high-quality, smooth Alps™ faders. These control  
individual source levels in the mix.  
CROSSFADER SECTION  
8. The Replaceable Crossfader achieves clean  
segues between the two selected input channels.  
"Hard left" selects Channel 1. "Hard right" selects the  
Channel 2. With the crossfader centered both channels  
are live. Use the crossfader for fast and seamless  
segues from one selected channel to the other.  
3. Treble, Middle, and Bass Controls are for  
setting appropriate equalized levels for the music you  
are playing. When turned all the way left they “CUT” the  
signal by -30dB for special effects mixing.  
4. Gain Controls are for accurately matching audio input  
levels of the channels.  
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!  
5. Microphone Controls are used to adjust input  
level and equalization level for your mic input. The  
talkover feature will bring down the level of the music  
while keeping the mic level up. This allows you to talk  
over the music.  
9. The Crossfader Control toggle allows the DJ to  
reverse the direction of the crossfader or turn it off. By  
reversing direction Channel 2 will be on the left and  
Channel 1 will be on the right.  
6. Microphone Jack for a 1/4” Microphone  
connector.  
7. KILL buttons (DM1002X only) 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.  
10. Transform Buttons are for quickly reversing the  
crossfader direction in order to create various special  
effects.

output level.  
12. The Program Mix controls the mix of Cue and  
Program audio in the headphones so that beats can  
be matched exactly and segues are smooth when a  
song is cued.  
16. 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.

6. The Phono/Line Inputs are unbalanced RCA  
jacks. The Line Input is selected with the  
Line/Phono Input switch above it.  
1. Power Connection. Plug your power adapter 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.  
Warning: make sure the LINE/PHONO input  
switch is set to line before playing any line  
input level devices through your mixer  
4. The Record Outputs are designed to be hooked  
up to your tape deck’s input jacks.  
5. The Phono Inputs use unbalanced RCA jacks.  
Your input signal is fed directly to your mixer’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.  
8. Line/Phono Input switch. Use this to allow line  
level equipment to be plugged into your phono inputs.
