VERY IMPORTANT  
Please read this entire manual before connecting this unit to your system  
For optimum performance:  
·
·
The crossfader is a user replaceable item and subject to wear. Excessive force can wear out the fader quickly. This is not a  
warranted item.  
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.  
·
·
Always make sure that AC power is OFF while making any connections.  
Use appropriate cables throughout your system. 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. 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.  
·
·
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.  
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.  
·
·
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 it’s 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 unit!

QUICK SETUP DIAGRAM  
Study this setup diagram. Make sure all faders are at "zero" and all devices are off. First, connect all stereo  
input sources. Next, connect your microphone(s) and monitor headphones. Finally, connect the stereo outputs to  
the power amplifier(s) and/or audio sources. Plug your mixer into AC power. Now you are ready to switch  
everything on. Always switch on your audio input sources such as turntables or CD players first, then your mixer,  
and finally any amplifiers. When turning off, always reverse this operation by turning off amplifiers, then your  
mixer, and then input devices.

We have divided this section into various functional  
blocks: Inputs, Microphone, Crossfader, Equalizer, Outputs,  
and Headphone Cueing. It is important to learn how each of  
these work.  
8. Neutrik™ “Combo” connector - allows connection  
of either a 1/4” jack or an XLR jack. This is ideal for  
connecting an XLR gooseneck directly into the mixer.  
CROSSFADER  
INPUTS  
9. Crossfader Assign Knob - determines which input  
channel will be heard when the crossfader is moved  
towards the knob.  
1. Input faders - control individual source levels in the  
mix.  
2. Input Toggle Switches - select which source will be  
live to that channel based on what you have connected to  
the rear panel input section.  
Note: All channels not assigned will remain active.  
10. Replaceable Crossfader - achieves clean segues  
between the two input channels selected by the Crossfader  
Assign.  
3. Pre-fader Gain Controls – adjust the pre-fader  
volume for cleaner sound.  
MICROPHONE  
4. Mic Gain Controls – The DJ Mic Fader controls  
the DJ Mic volume for the Neutrik™ “Combo”  
connector. The Mic 2 Fader controls the Mic volume  
for the 1/4” connector on the rear of the mixer.  
In this example "Hard left" selects Channel 1 and "Hard  
right" selects Channel 4. With the crossfader centered,  
both assigned channels are live. Use the crossfader for fast  
and seamless segues from one selected channel to the  
other.  
5. Mic Talkover/On/Auto-Talkover Switch –  
controls DJ Mic only. Mic 2 activation is controlled only  
through the Mic 2 level fader.  
Note: The crossfader is user replaceable in case of failure.  
Simply unscrew the two large screws that 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  
- you’re back in business!  
Talkover turns down the input level of your music  
sources from Channels 1-4.  
Auto-Talkover automatically reduces the input level of  
Channels 1-4. This works with the talk-over  
sensitivity adjustment. Talkover is very useful for  
making announcements without adjusting any levels.  
11. Fader Start – activates the crossfader to send play and  
cue commands to your auto-start Numark CD player or  
other popular brand. For fader start, attach your mixer to a  
remote start CD player using industry standard  
6. Talkover sensitivity adjust – determines the point  
in which auto-talkover activates. The more sensitive the  
adjustment, the quieter you need to speak into your  
microphone to activate auto-talkover.  
1/8”(3.5mm) cables. When you move the crossfader  
toward the active channel, the attached CD player will  
start. When it is moved away, that side will cue (similar  
to pressing the cue button).  
7. Treble and Bass Controls – for fine-tuning the tone  
of your voice on both mics through the sound system.  
The controls are detented for setting tone "flat". For best  
results, use a dynamic cardioid microphone.

EQUALIZER  
OUTPUTS  
12. 5-Band Stereo Graphic Equalizer (EQ) -  
compensates for differences in source material sound  
quality. In ultra-compact mobile systems this EQ can be  
used to tailor the sound to the acoustical requirements of  
the room. Center frequencies are 63Hz, 250Hz, 1kHz,  
4kHz and 16kHz. Faders have a center detent for an  
accurate "flat” response.  
14. Master Fader – to control the overall output level.  
15. Stereo/Mono toggle - adjusts the Master output for  
stereo or mono operation.  
16. Panning – adjusts the balance of right to left audio.  
17. Booth/Zone Fader - controls speaker volume for a  
remote zone or booth monitors.  
Below is a typical "house" EQ curve. Notice how the  
knobs above "0" balance out the knobs below. Start with  
this setting if you've never used a graphic EQ before:  
NOTE: This can also be used to supply line level audio to a  
lighting controller or to lights that are sound activated.  
18. Meter Assign – determines whether pre-fader or master  
audio is sent to the stereo LED meter. PFL signal is  
determined by the cue assign switches.  
19. Stereo Auto Peak Hold Level Indicator- quickly  
and accurately tracks level of audio sent to it by the meter  
assign. The red LEDs for +3dB, +5dB and +8dB hold  
program peaks for a second or two. With peak metering,  
it's OK to be "in the red" as long as +5dB or +8dB aren't  
constantly lit. When using as a master output  
meter, set the crossover, equalizer and power amp inputs  
to avoid distortion at each step in the audio chain. Proper  
attention to the peak meter results in the punchiest  
possible sound without audible distortion. When used  
to adjust the PFL levels, accurately match channel  
levels with the Pre-fader gain controls before mixing them  
together. The idea is to properly match PFL inputs, not  
the input with the stereo output meter!  
Below is an example of a poor EQ curve because it cuts  
the output volume down by 6-12dB. You have to  
compensate by running the Master output higher:  
HEADPHONE CUEING  
20. Channel Cue/Send Assign - are used to route PFL  
channel audio to the Monitor Section. The channel  
faders do not control the Cue send volume. This audio is  
also sent to a rear panel output for use with an external  
sampler or other source such as booth monitor.  
Below is the worst sort of curve to use because you are  
using EQ to add volume. With exaggerated boost, you can  
easily run your power amplifiers into “clipping” and  
damage your speakers.  
21. Split/Blend Cue – controls how PFL and Program  
audio are sent to your headphones. In split mode, the  
PFL audio can be heard in your left ear and PGM audio  
can be heard in your right ear. In blend mode, both PFL  
and PGM can be heard in both ears.  
22. Headphone Mix - controls the mix of PFL and PGM  
signals to your headphones. When the slider is moved to  
the left, all you will hear is the cue source. When the  
slider is all the way right, you will hear what is playing  
through the master output. By blending, beats can be  
matched exactly and segues can be smooth when a song is  
cued.  
GENERAL EQ HINTS  
• Boost the 63Hz band for deep bass tones and solid kick  
drum sound. Use sparingly because this dramatically  
increases demand on power amplifiers and could drive  
them into “clipping” .  
• Cut slightly at 250Hz and more at 1kHz for extra  
clarity.  
23. Headphone Level – to adjust cue volume.  
Note: Cutting is preferable to boosting.  
• Boost 16kHz for a little "sizzle".  
24. Headphone Input – for your 1/4” headphone.  
As a general rule, less equalization is  
better!  
25. 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.  
13. EQ ±6/12dB adjust – sets the amount of adjustment  
you can make with the equalizer.  
26. Power Button – turns unit off and on.

27. Phono Inputs – for attaching your turntables. When  
these connectors are used, your signal is fed directly to the  
high-quality RIAA phono pre-amplifiers. Use this  
position only for turntables. Line level sources will  
overload the sensitive phono pre-amps and will cause  
distortion.  
32. Cue/Send Output – to temporarily send channel PFL  
signal to an external sampler or other source such as both

33. Record Outputs – are unbalanced RCA jacks used to  
send the output of the program to any connected recording  
device.
