VERY IMPORTANT
Please read this section before connecting this unit to your system
For optimum performance:
•
All the slide faders are subject to wear. Excessive force can wear out the fader quickly. User replaceable
slide faders are 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 use.
•
Never attempt to make any adjustments other than those described in this manual, or repairs. 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
equipment 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 near or on top of the unit!
• Headphone outputs can be set to levels which can cause damage to your ears. Use caution.
• This unit may contain a microcomputer for signal processing and control functions. In very rare situations,
severe interference, noise from an external source, or static electricity may cause it to lockup. In the
unlikely event that this should happen, turn off the unit, wait at least five seconds, and then turn it back on
again.
