IMPORTANT INFORMATION.

Please read this entire manual before connecting the DM2002X to your system. For optimum performance: 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. 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. 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. 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. 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. 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 O N 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. Use restraint when operating controls. Try to move them slowly. Rapid adjustments could damage speakers due to amplifier clipping. 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 its limits. Amplifier distortion is THE major cause of speaker failure. 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!

A NOTE ON CABLES: 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.

GUIDED TOUR OF FEATURES AND OPERATING INSTRUCTIONS.
If the D M X 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 D M X can be 10 rack-mounted or used as a freestanding 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 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 D M X 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. To rotate or replace the toggle a. Turn off all power! b. Remove corner screws c. To rotate lift of toggle and place in its new position or to replace unplug the old unit and plug in the new one. d. Screw toggle back into place. 2. The Input Faders are low-noise, low-impedance, high-quality, smooth Alps faders. These control individual source levels in the mix. 3. PFL and Channel Cue Assign. The P F L pushbuttons are used to route channel audio to the main volume meter and the Cue Monitor Section. 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 channels gain control. The idea is to properly match inputs, not the input with the output!

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. 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. 6. Gain Controls are for accurately matching audio levels of the channels. 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.

CROSSFADER SECTION 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. N o t e : 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 its cable. Re-attach the new crossfader and screw the mounting plate back onto the unit - youre back in business! 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. 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. 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. 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. CUE SECTION 15. The C U E 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 P F L audio is sent to the headphone amp using the PFL Assign 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. 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. 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 D M X.
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.

6. Channels 2 and 3 Line Inputs are unbalanced RCA jacks. The Line Input is selected with the toggle switch on the front panel. 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. N O T E : Plug mono audio sources into both Left and Right inputs using a Y cable connector. 7. Phono Inputs on Channels 1, 2 and 3 use unbalanced RCA jacks. Your input signal is fed directly to the D M X's high-quality RIAA phono preamplifiers 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 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
1. AC Connection. Plug your power cord in here. See safety precautions on page 3 for proper treatment of the power cord. 2. GND is the grounding lug for all turntables. Always use this connection (your turntable cable should have a grounding wire). 3. The Stereo Main Outputs are low-impedance RCA connectors controlled by the Master fader. 4. The Stereo Booth/Zone Outputs are lowimpedance unbalanced RCA jacks controlled by the Zone Level control. 5. S e n d O u t p u t is set by the send buttons pressed on the front panel. Hook up you sampler or other processor here.
