Connecting the Unit
CAUTION
Disconnect the negative (–) terminal of the battery
to avoid the risk of short-circuit and damage to
the unit.
Secure the wiring with cable clamps or adhesive
tape. To protect the wiring, wrap adhesive tape
around it where they lie against metal parts.
Do not route wires where they will get hot, for
example where the heater will blow over them. If
the insulation heats up, it may become damaged,
resulting in a short-circuit through the vehicle
body.
Make sure that wires will not interfere with mov-
ing parts of the vehicle, such as the gearshift,
handbrake or seat sliding mechanism.
Do not shorten any wires. Otherwise the protec-
tion circuit may fail to work when it should.
Never feed power to other equipment by cutting
the insulation of the power supply wire to tap
from the wire. The current capacity of the wire
will be exceeded, causing overheating.

System remote control wire (sold separately)
Connect the male terminal of this wire to the system remote control
terminal of the car stereo (SYSTEM REMOTE CONTROL). The
female terminal can be connected to the auto-antenna relay control
terminal. If the car stereo does not have a system remote control ter-
minal, connect the male terminal to the power terminal through the
ignition switch.

Setting the Unit
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 gain controls to the NORMAL
position. If the output is low, even when
the volume of the car stereo is turned up,
turn these controls clockwise. If there is
distortion 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.
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.
Power Indicator
The power indicator lights when the
power is switched on.
Input Select Switch
For two-channel input, slide this switch
to the left. For four-channel input, slide
this switch to the right.
Cut Off Frequency Control
If the LPF/HPF select switch is set to
LPF or HPF, you can select a cut off
frequency from 40 to 120 Hz.
LPF (Low-Pass Filter)/HPF (High-Pass Filter) Select Switch
Set the LPF/HPF select switch as follows according to the type of 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) * 40 to 120 Hz Subwoofer Connect a subwoofer.
OFF (center) Full range Full range
HPF (right) * 40 to 120 Hz Full range Use if you want to cut the
very low frequency range*
because it is not necessary
for the speakers you are
using.
* See the Cut Off Frequency Control section.

To prevent damage
Do not ground the speaker wire directly or con-
nect a negative () lead wire for several speakers.
This unit is for vehicles with a 12-volt battery and
negative grounding. Before installing it in a recre-
ational vehicle, truck or bus, check the battery
voltage.
If the car stereo is kept on for a long time while
the engine is at rest or idling, the battery may go
dead. Turn the car stereo off when the engine is at
rest or idling.
If the system remote control wire of the amplifier
is connected to the power terminal through the
ignition switch (12 V DC), the amplifier will
always be on when the ignition is on regardless
of whether the car stereo is on or off. Because of
this, the battery could go dead if the engine is at
rest or idling.
Speakers to be connected to the amplifier should
conform with the standards listed below. If they
do not conform, they may catch fire, emit smoke
or become damaged. The speaker impedance must
be 2 to 8 ohms. But in case of two-channel and
other bridge connections, the speaker impedance
must be 4 to 8 ohms.
Install and route the separately sold battery wire
as far away as possible from the speaker wires.
Install and route the separately sold battery wire,
ground wire, speaker wires and the amplifier as
far away as possible from the antenna, antenna
cable and tuner.
Cords for this product and those for other prod-
ucts may be different colors even if they have the
same function. When connecting this product to
another product, refer to the supplied Installation
manuals of both products and connect cords that
have the same function.
