8. OPERATIONS AND SPECIFICATIONS
-SETTING THE UNIT
Speaker Out A: LPF (Low-Pass Filter)/HPF (High-Pass Filter)
Select Switch
Set the LPF/HPF select switch as follows according to the type of the
speaker that is connected to the speaker output connector and the car
stereo system:
LPF/HPF Select Audio frequency range Speaker Remarks
Switch to be output Type
LPF (left) Very-low-frequency range Sub-woofer Connect a sub-woofer.
OFF (center) Full range Full range
HPF (right) Low-frequency range to Tweeter If you want to cut the very-
high-frequency range low-frequency range
because it is not necessary
for the speaker you use.
Gain Control
Adjusting the gain controls A and B will
help match the output of the car stereo
to the Pioneer amplifier. Normally, set
the switch to the “NORMAL” position.
If the output is low even when the vol-
ume of the car stereo is turned up, turn
these controls clockwise. If there is dis-
tortion when the volume of the car
stereo is turned up, turn these controls
counter-clockwise.
• If you only use one input plug, set the gain
controls for speaker outputs A and B to the
same position.
• Set the gain control to “NORMAL” when
this amplifier is connected to a Pioneer car
stereo with RCA output jacks. If the sound
is too low or distorts, adjust the gain con-
trol.
RCA Input Select Switch
For two-channel input, slide this switch
to the left. For four-channel input, slide
this switch to the right.
Power Indicator
The power indicator lights when the
power is switched on.

of the amplifier to the positive (+) terminal of
the battery.
2. Connect the wires to the terminal.
• Fix the wires securely with the terminal
screws.
1. Expose the end of the speaker wires
by about 10 mm and twist it using
nippers or a cutter.
2. Attach lugs to speaker wire ends.
• Use pliers, etc., to crimp lugs to wires.
