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

working beyond it’s limits. Amplifier distortion is THE major cause of
speaker failure.
