b) Retain Instructions - The safety and operating instructions should be

kept for future reference.

c) Heed Warnings - All warnings on this product and in these operating

instructions should be followed.

d) Follow Instructions - All operating and other instructions should be

followed.

e) Water and Moisture - This product should be kept away from direct

contact with liquids.

f) Heat - Avoid placing this product to close to any high heat sources such

as radiators.

g) Ventilation - The appliance should be situated so that it’s location or

position does not interfere with it’s proper ventilation. For example, the

appliance should not be situated on a bed, sofa, rug, or similar surface

that may block the ventilation opening; or, placed in a built-installation,

such as bookcase or cabinet that may impede the flow of air through the

ventilation openings.

h) Power Sources - This product should be connected to a power supply

only of the type described in these operating instructions, or as marked

on the unit.

i) Power Cord Protection - Power supply cords should be routed so that

they are not likely to be walked upon or pinched by items placed on or

against them. When removing the cord from a power outlet be sure to

remove it by holding the plug attachment and not by pulling on the cord.

j) Object and Liquid Entry - Take care that objects do not fall into and that

liquids are not spilled into the inside of the mixer.

k) Cleaning – The appliance should be cleaned only as recommended by

the manufacturer.

l) Non-use Periods – The power cord of the appliance should be

unplugged from the outlet when left unused for long periods of time.

m) Damage Requiring Service - Only qualified personnel should service

this product. If you have any questions about service please contact

Numark at the number(s) shown on the back cover of this manual.

n) Grounding or Polarization - Precautions should be taken so that the

grounding or polarization means built into the CD player is not

defeated.

o) Internal/External Voltage Selectors - Internal or external voltage selector

switches, if any, should only be reset and re-equipped with a proper plug

for alternative voltage by a qualified service technician. Do not attempt

to alter this yourself.

p) Carts and Stands －The appliance should be used only with a cart or

stand that is recommended by the manufacturer of the cart or stand for

this purpose. An appliance and cart combination should be moved with

care. Quick stops, excessive force, and uneven surfaces may cause the

appliance and cart combination to overturn.

q) Do not defeat the safety purpose of the polarized-type plug. A polarized

plug has two blades with one wider than the other. The wide blade is

provided for you safety. When the provided plug does not fit into your

outlet, consult an electrician for replacement of the obsolete outlet.

r) Only use attachments/accessories specified by the manufacturer.

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.

•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.

MIXER FEATURES

1. Input fader - Controls individual source levels in the mix.

2. Input toggle switch - Selects which source will be active based on what you have connected to the rear panel input section.

3. Treble and Bass EQ - Adjusts the high and low frequency levels of the input channels for good sound.

4. Channel Gain – Adjusts the pre-fader volume for cleaner sound.

5. Replaceable Crossfader - Achieves clean segues between the two input channels. "Hard left" selects Channel 1. "Hard right"

selects Channel 2. With the crossfader centered, both assigned channels are live. Use the crossfader for fast and seamless segues

from one selected channel to the other.

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!

6. Mic Input Gain – Adjusts microphone level.

7. Mic Input – Insert your Microphone with ¼” plug in here.

8. Headphone Input – Insert in the ¼” plug for your headphones here.

9. Channel Cue - Used to preview channel audio to your headphones. Listen here before bringing up channel faders or moving the

crossfader.

10. Headphone Level – Adjusts cue volume.

11. Master Fader - Controls the overall output level.

REAR PANEL

12. Phono Inputs – Plug your turntables in here. 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.

13. Ground - Grounding lug for turntable connection. Always use this connection when using turntables. (your turntable cable should

have a grounding wire)

14. Line Inputs - Unbalanced RCA jacks for connecting stereo audio from line level sources such as CD players, HiFi VCRs, cassette

and reel-to-reel tape decks, DAT machines, laser discs, tuners, even synthesizers or other mixing consoles.

NOTE: Plug mono audio sources into both Left and Right inputs using a "Y" cable connector.

15. Stereo Main Outputs - Unbalanced RCA connectors controlled by the Master fader.

16. Power Connector - Plug in power adapter here and check the voltage level to match your country’s standard.

17. Power Switch – turns unit off and on.

QUICK SETUP DIAGRAM

Study this setup diagram. Make sure all faders are at "zero" and all devices are off. First, connect all

input sources and processors. Next, connect your microphone and monitor headphones. Finally, connect the

stereo outputs to the power amplifier(s) and/or audio receivers such as tape decks. Plug your mixer into AC

power. Now you are ready to switch everything on. IMPORTANT: 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.
