1 Speaker Terminals
These terminals are 14K Gold plated for high conductivity and minimum impedance loss. The terminals face upwards for easy wiring in tight situations.
2 Fuse
Protects the amplifier as well as the automobile electrical system from short circuit conditions.
3Power Supply Terminals
4Input 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.
5 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.
6 Bass Boost Control
Allows you to increase the bass signal level sent to the speakers
7 Low Pass Control
Permits you to adjust the crossover frequency from 35 Hz to 400 Hz to suit the subwoofers
8 High Pass Control
Permits you to adjust the crossover frequency from 80 Hz to 2.5 kHz to suit the tweeters
9 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
10 Low Level Input (High Impedance)
This unit is provided with
11 Power LED Indicator
This LED is illuminated when the REMOTE ON system is turned on.
12 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.
