VERY IMPORTANT
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.
• Never attempt to make any adjustments or repairs other than those described in this manual. Take the unit to your dealer or to an
authorized Numark Service Center.
• 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.
• 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 unit!
