For optimum performance:

•

The crossfader is a user replaceable item and subject to wear. Excessive force can wear out the fader quickly.

•

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

This is not a warranted item.

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.
