Setting the Unit
Gain Control and Bass Level
Control
Adjusting the gain controls A and B and
the bass level control (CH SUB) will
help match the output of the car stereo
to the Pioneer amplifier. Normally, set
these controls to the “NORMAL
(NORM.)” position. If the output is low,
even when the volume of the car stereo
is turned up, turn these controls clock-
wise. If there is distortion when the vol-
ume 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.
When using with an RCA equipped car
stereo (standard output of 500 mV), set to
the NORMAL position. When using with
an RCA equipped Pioneer car stereo with
max. output of 4 V or more, adjust level to
match the car stereo output level.
When you want to boost bass, turn the bass
level control clockwise.
Power Indicator
The power indicator lights when the
power is switched on.
HPF (High-Pass Filter) Select Switch (CH A and CH B)
Set the HPF select switch as follows according to the type of speaker that is connected to the
speaker output connector and the car stereo system:

HPF (Right) Low Frequency range to Full range Use if you want to cut the

because it is not necessary
for the speakers you are

AM broadcast with your car stereo,

About This Product
This product is a 5-channel Class D amp.
Connect full range speakers to channels A
and B, and a subwoofer to the SUB chan-
nel.
For the SUB channel, if both L (left) and R
(right) are connected to the RCA input,
output is a mixture of the L and R signals.
WARNING
Always use the special red battery and ground
wires ([RD-223]
×
2), which are sold separately.
Connect the battery wire directly to the car battery
positive terminal (+) and the ground wire to the
car body.
Do not touch the amplifier with wet hands.
Otherwise you may get an electric shock. Also, do
not touch the amplifier when it is wet.
For traffic safety and to maintain safe driving
conditions, keep the volume low enough so that
you can still hear normal traffic sound.
Check the connections of the power supply and
speakers if the fuse of the separately sold battery
wire or the amplifier fuse blows. Detect the cause
and solve the problem, then replace the fuse with
another one of the same size and rating.
To prevent malfunction of the amplifier and
speakers, the protective circuit will cut the power
supply to the amplifier (sound will stop) when an
abnormal condition occurs. In such a case, switch
the power to the system OFF and check the
connection of the power supply and speakers.
Detect the cause and solve the problem.
Contact the dealer if you cannot detect the cause.
To prevent an electric shock or short-circuit
during connection and installation, be sure to
disconnect the negative () terminal of the battery
beforehand.
Confirm that no parts are behind the panel when
drilling a hole for installation of the amplifier. Be
sure to protect all cables and important equipment
such as fuel lines, brake lines and the electrical
wiring from damage.
