XIA SERIES
OPERATION
Configuration/Setup
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
counter clockwise. 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 counter clockwise to provide the best match.
The crossover is used to filter out frequencies above or
below a certain point. Choose
LP
when using the amplifier
with subwoofers,
HP
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 (
