OPERATION

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 crossover
Control
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 limit
(AXA10D)
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).
