INSTALLATION

Configuration/Setup

Input level Control

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.

Crossover Mode

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

FLAT when using with coaxial-type speakers.

Note: Choose FLAT 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.

Crossover Frequency

This control allows precise adjustment of the

Control

crossover frequency.

Bass Boost

This control provides additional boost @ 45Hz

when used with subwoofers. Adjust this control

with caution - as improper use can damage

speakers!

Subsonic Filter

Setting this control to the desired frequency will

(AX70SM)

limit harmful frequencies below the setting from

going to the subwoofer(s), preventing possible

damage from frequencies that subwoofers are not

designed to handle.

LED Indicators

The green LED indicator illuminates during normal

operation (POWER) and the red LED indicator

is visible when the amplifier detects a fault

(PROTECT).
