PRODUCT OVERVIEW

Front Panel

1. POWER: Turns the amplifier on or off.

2. LED: The LED illuminates green when power is applied.

3. PHASE: The PHASE setting allows you to compensate for the subwoofer location

relative to the main speakers. Adjust the PHASE setting a level that results in the

highest subwoofer audio output.

4. CROSSOVER: The CROSSOVER sets the frequency of the low-pass filter, below

which audio signals will be sent to the subwoofer connected to the amp.

5. VOLUME: Sets the level of the audio output in relation to the main speakers. Set it

to an appropriate level for a smooth, natural sounding transition between the main

speakers and the subwoofer.

Rear Panel

1. INPUT: Two RCA jacks for connecting a stereo or mono line level input.

2. SPEAKER LEVEL OUT: A speaker level output that passes through the audio

connected to SPEAKER LEVEL IN. Connect full-range speakers appropriately rated

for the power level of the amplifier connected to SPEAKER LEVEL IN. The VOLUME

control on the front panel does not affect the volume level of speakers connected

to SPEAKER LEVEL OUT.

3. SPEAKER LEVEL IN: A speaker level input for connecting the speaker level outputs

of an audio amplifier or AV receiver. The audio from this input is passed to the

SPEAKER LEVEL OUT connector, without any modification by the amp.

4. TRIGGER: A 3.5mm TS jack for connecting a 12-24V trigger signal. When DC voltage is

detected, the amplifier turns on, and when DC voltage is removed, the amplifier

turns off.

5. SUB OUT: A 5-way binding post for connecting a subwoofer. The output signal will

be modified by the PHASE, CROSSOVER, and VOLUME settings on the front panel.

6. AC IN: An IEC 60320 C8 panel connector for attaching the included AC power cord.
