GX1200.6 Multi-Channel Power Amplifier 1 1 2 3 POWER/PROTECT LED Amplifier status indicator. Blue indicates all systems working and amplifier is on. Red indicates protection mode, from Thermal or Short Circuit. (See Troubleshooting) GROUND (GND) This must be connected to the negative terminal of the car’s battery or bolted to a clean, unpainted part of the chassis of the vehicle. Bad grounds account for 90% of amplifier issues, make sure the amplifier is grounded correctly and securely.

4 5 6 7 8 INPUT GAIN (SENS) CH 1/2, 3/4, 5/6 Used to adjust the input sensitivity to match the input level signal on the channels. Continuously variable from 0.4V to 10V. Adjust this with the help of a DMM and a test signal or an Oscilloscope. See System Tuning section for basic setup instructions. 5 CROSSOVER (X-OVER) CH 1/2, 3/4, 5/6 High Pass Filter (HPF): When set, activates a highpass crossover for the channels. Continuously variable from 40Hz to 500Hz using the FREQ dial.

Amplifier Owner’s Manual SYSTEM TUNING 1. Install all system fuses. 12. Repeat sensitivity level adjustments for all other amplifiers. 2. Set the amplifier’s input sensitivity controls to their minimum positions (full counterclockwise). 13. Reduce the headunit’s volume to a comfortable level. 3. Set all amplifier crossover switches according to your system’s design. 4. Make preliminary adjustments to the crossover frequency, usually 80Hz is a good starting point for high and low pass.
