XPE 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 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 blue during normal operation
(POWER) and red when the amplifier detects a fault
(PROTECT).
