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.
Speaker Out A: Bass Boost
Level Control
Bass boost level control can boost the
level around the frequency selected by
the bass boost frequency control to 0 to
12 dB.
Speaker Out A: Bass Boost
Frequency Control
(GM-X424)
You can select a bass boost frequency
from 40 to 120 Hz with the bass boost
control.
• Bass Boost Level Control, Bass Boost

when the LPF/HPF select switch is set to a
position other than HPF.
Speaker Out B: HPF (High-Pass Filter) Select Switch
Set the HPF select switch as follows according to the car stereo system
and the type of the speaker that is connected to the speaker output:
HPF Select Audio frequency range Speaker Remarks
Switch to be output Type
OFF (left) Full range Full range
HPF (right) Low-frequency range to Tweeter If you want to cut the very-
high-frequency range low-frequency range

• Be sure to use the special red battery wire
supplied with the amplifier and connect directly
to the battery. Use the supplied black ground wire
and connect to the vehicle body.
1. Pass the battery wire from the
engine compartment to the interior
of the vehicle.
• After making all other connections to the
amplifier, connect the battery wire terminal
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.
3. Connect the speaker wires to the
speaker output terminals.
• Fix the speaker wires securely with the termi-
nal screws.
