CONTROLS & FUNCTIONS

1. Bass Boost Gain Remote Control

This plug connects the amplifier and the remote bass knob using the supplied cable.

2. Input Sensitivity Control

This control adjusts the amplifier's input sensitivity. The input sensitivity is variable from 200 Millivolts to 8
volts. Turning clockwise increases sensitivity. Turning counter clockwise decreases sensitivity. This knob
is not a volume control for the amplifier. The amplifier can be driven to full power with a wide range of
input signals. A lower signal level will require increased sensitivity to reach full power. A higher signal level
will require decreased sensitivity.

3. Low level Input RCA Jacks

These inputs are for signal cables from the source. Always use high quality, shielded RCA cables.

CONTROLS & FUNCTIONS

4. Low Level LINE OUT RCA Jacks

The LINE OUT allows you to build a multiple amplifier system without having to use splitter cords or
Y-adapters to distribute the signal. Now it is simply a matter bringing one set of RCAs into the first
amplifier, then using the line out RCA jacks as the feed to the next amplifier.

5. Bass Boost Control

By using the bass boost function, bass notes at 45Hz are emphasized as much as 18dB.

6. Phase Shift Control

Allows you to change the phase of your subwoofer from 0 to 180 degrees to help compensate for timing
differences between drivers.
