The terminals face upwards for easy wiring in tight situations. Fuse Protects the amplifier as well as the automobile electrical system from short circuit conditions. 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. Crossover Mode Switch In a full range system, set this to FULL. If the amp is being used to power a crossover system, set to either HPF or LPF as needed. Bass Boost Control Allows you to increase the bass signal level sent to the speakers Low Pass Control Permits you to adjust the crossover frequency from 35 Hz to 400 Hz to suit the subwoofers High Pass Control Permits you to adjust the crossover frequency from 80 Hz to 2.5 kHz to suit the tweeters High Level Input (Low Impedance) Use these if your car stereo does not have RCA output jacks: connect the speaker output from the head unit to these inputs 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. Power LED Indicator This LED is illuminated when the REMOTE ON system is turned on. 1112 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 pr...
