AMPLIFIER FEATURES:

LINK - Link will allow the user to daisy-chain one amplifiers signal input into another amplifier. Plug the signal source outputs into the 

first amplifier’s input, patch from the amplifier’s LINK jacks to the next amplifier’s input, and so on, daisy-chaining as many amplifiers 

as there is no excessive level loss.
OPERATING VOLTAGE (AC MAINS) - The correct AC main voltage is listed above the Power Cord input. Connecting to the wrong 

voltage is dangerous and may damage the amplifier.
GAIN CONTROLS - The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to 

adjust the amplifier so no “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion 

during normal operation.
LED INDICATORS - Each channel has eight LEDS. The bottom LED is the channel power indicator. The next five LEDs indicate signal 

level activity. One red LED indicates signal clipping and the other red LED indicates protections mode for shorts/ overload.
