CAUTION Do not open risk of electric shock
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE COVER RACK. REFER SERVICE TO YOUR AUTHORIZED AMERICAN DJ AUDIO DEALER.
The lightning flash with an arrow triangular symbol is intended to alert the user to the presence of uninsulated "dangerous voltage" within the products enclosure, and may be of sufficient magnitude to constitute a risk of electric shock. The exclamation point triangular symbol is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the user manual accompanying the CD player.
For optimum performance and reliability DO NOT PRESENT THE AMPLIFIER WITH A SPEAKER LOAD OF LESS THAN 2 OHMS. [. . . ] This will eliminate 60Hz cycle Hum that is sometimes induced when mounting several units in the same rack.
OPERATING VOLTAGE
(AC mains)
The serial number label indicates the correct AC main voltage. Connecting to the wrong voltage is dangerous and may damage the amplifier.

The limiter has a fixed threshold and will prevent continuous clipping. Below clipping, and during short clips on peaks, the limiter does not act on the audio signal. The limiter for either channel can be disabled independently using the slide switch on the front panel.

OPERATION
CONFIGURING THE AMPLIFIER
A 4-position dip switch on the rear panel allows you to configure certain amplifier characteristics. A diagram on the rear panel shows the individual switch functions and settings. .
LOW-CUT FILTER: Setting position 1 to "ON" enables the low-cut
filter on channel 1 and "OFF" disables it. 30 50 LOW-CUT FILTER FREQUENCY SELECTOR: When setting position 1 or 4 to "ON" then position 2 or 3 up to cut-off of 30 Hz and down is for 50 Hz.
GAIN CONTROLS
The gain controls are located on the front panel and are calibrated in DB of attenuation from full gain. It is best to adjust the amplifier so no "hissing" is heard from speakers with no music being played.
LED INDICATORS
Each channel has 6 LEDS. 2 green LED and 2 yellow LED for level indication, 1 red LED for power clips, 1 red LED for short / overload, and the green LED at center for power indicator.
BUILT IN PROTECTION
LIMITER: During signal overload, the limiter will reduce the input audio signal enough to minimize the amount of clipping. During normal operation, the limiter does not affect the audio signal. It will allow brief clipping of peaks and will only activate when continuous, hard clipping occurs. When the signal amplitude decreases enough that clipping ends, the limiter will deactivate and cease its gain reduction. [. . . ] no sound output), during the "SHORT CIRCUIT PROTECTION. " SHORT CIRCUIT PROTECTION can usually be traced back to the signal output line (i. e. If this line is good, check the internal speaker connections and components. A short circuit will usually be traced to a bad cable or a bad speaker and is rarely traced to the amplifier itself.
