Take the DM900 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. · Reliability will be enhanced through the use of banana connectors on the speaker wires. · 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. · 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. · 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! A NOTE ON CABLES: Make the input and output connections with readily available low-capacitance stereo cables. See your Numark dealer or an electronics or audio specialist store if you are not sure which cables to get.
