CONTROLS & FUNCTIONS

8

7. Low-Pass Filter Control

For use as a dedicated subwoofer channel, set the filter switch to the "LPF" (Low Pass Frequency). Adjust the variable crossover frequency with control knob as desired. The amplifier input circuit filters out everything above 50Hz ... 150Hz (dependant on the adjustment of the frequency control), so only the lowest bass notes are amplified.

8. Sub Sonic Control

The sub sonic control will cut all frequencies below what it is set to from going to your sub(s). This will prevent your subs from playing any frequencies that may harm them.

9. Bridged Connection

This is the connection used to bridge 2 two of the same class D amplifiers together. Later in this manual it is explained how to bridge the amps and what settings to use.

10. Light Switch

This switch is used to tun the extrnal lights on and off. When set to the off position, only the power/protection lights, volt-meter and clipping lights will stay on.
