DM1885X
IMPORTANT INFORMATION...
Please read this entire manual before connecting the DM1885X 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 DM1885X to your dealer or to an authorized Numark Service Center.
A NOTE ON CABLES:

SYSTEM PRECAUTIONS
•Use appropriate cables throughout your system: Quality shielded audio cables and terminated shielded video cables, low- capacitance preferred. Speaker cables must be
•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
•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 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 mixer!
