Very Important
Please read this section before connecting this unit to your system:
For optimum performance:
• All slide faders are subject to wear. Excessive force can wear out the faders quickly. User-
replaceable slide faders are not covered by our warranty.
• 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 32
feet / 10 meters). 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. Cable quality 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 8–10 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 its limits. Amplifier distortion is the main 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.
• Under rare circumstances, if this product is exposed to electromagnetic interference during use,
there may be a slight drop in signal-to-noise ratio.
• Intended electromagnetic environments: residential, commercial, light industrial, urban outdoors.
