The input level control (gain) is used to obtain the best possible match between the head unit audio output and the amplifier input. Begin by turning the input level control fully counterclockwise. Next, turn up the head unit volume control around 3/4 of the way up. Adjust the input level control clockwise until audible distortion is heard, then slightly counterclockwise to provide the best match. Repeat for all input level controls.

Select 2 CH mode if the head unit only has 1 pair of RCA outputs. Plug the RCA’s from the head unit into channels 1/2 or 3/4. All 4 amplifier inputs will receive a signal.

NOTE: There is no fader function when using 2 CH mode.

Select 4 CH mode if the head unit has 2 pairs of RCA outputs. Plug the RCA’s from the head unit into channels 1/2 and 3/4.

The crossover is used to filter out frequencies above or below a certain point. Choose LPF when using the amplifier with subwoofers, HPF when using with midrange/tweeter combinations and FULL when using with coaxial-type speakers.

NOTE Choose FULL when using the amplifier in stereo/ bridged simultaneous mode. In this mode, passive crossovers are required. Failure to use the correct passive components may damage the amplifier and/or speakers. Consult a qualified professional for recommendations.

This control allows precise adjustment of the crossover frequency.

This control provides additional boost @ 45Hz when used with subwoofers. Adjust this control with caution - as improper use can damage speakers!

The LED indicator illuminates green during normal operation (POWER) and red when the amplifier detects a fault (PROTECT).
