Power Supply Terminals Input Level Control Use this control to match the output of the head unit to the amplifier. If distortion is present, reduce the setting of this control. Phase Shift Switch Allows you to change the phase of your subwoofer from 0 degree to 180 degrees to help compensate from timing difference between drivers. High Pass Subsonic Filter Adjustable from 15Hz to 40Hz with a slope of 24dB per octave.This allows for the attenuation of frequencies that are mostly inaudible and cause unnecessary strain on the amplifier. Crossover Low Pass Filter Adjustable from 20Hz to 250Hz with a slope of 24dB per octave.This allows for the adjustment of the upper point of the frequency bandwidth and the respective subwoofer. Low Level Input (High Impedance) This unit is provided with gold-plated RCA input jacks. Using RCA-RCA type patch cords, connect these inputs to the RCA outputs from your head unit. 5 Low Level Output (High Impedance) This unit is provided with gold-plated RCA Output jacks. Using RCA-RCA type patch cords, connect these Outputs to the RCA Inputs for your anyther amplifier. Protection LED Indicator The protection circuitry in the amp will disable it if it senses an input overload, speaker short circuit, or thermal overload conditions. Should this occur, the PROTECT LED will be illuminated. At that time, it is important that you check to determine what has caused the protection circuitry to become activated. If the amp shut off because of a thermal overload, allow it to cool down before attempting to restart. If the shutdown occured because of an input overload, or speaker short circuit, be sure to correct these conditions before attempting to restart the amp. To reset the amp, turn the REMOTE power off and on again. Power LED Indicator This LED is illuminated when the REMOTE ON system is turned on.
