IMPORTANT INFORMATION...

Please read this entire manual before connecting the DM1200 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 or oils 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 DM1200 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, labeled 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.

• Use restraint when operating controls. Try to move them slowly. Rapid adjustments could damage speakers due to amplifier clipping.

A NOTE ON CABLES:

Make the input and output connections with readily available low-capacitance stereo cables.

Quality cables make 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 purchase.

• 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!
