Setting the Unit
<ENGLISH>
Thank you for purchasing this PIONEER
product. Before attempting operation, be
sure to read this manual.
In case of trouble
When the unit does not operate properly,
contact your dealer or the nearest autho-
rized PIONEER Service Station.
CAUTION
Never replace the fuse with one of greater
value or rating than the original fuse. Use
of an improper fuse could result in over-
heating and smoke and could cause dam-
age to the product and injury including
burns.
CAUTION
Do NOT install or use your Pioneer ampli-
fier by wiring speakers rated at 4 Ohm (or
lower) in parallel to achieve a 2 Ohm (or
lower) bridged mode (Diagram B).
Amplifier damage, smoke, and overheating
could result from improper bridging. The
amplifier surface could also become hot to
the touch and minor burns could result.
To properly install or use a bridged mode
for a two-channel amplifier and achieve a 4
Ω
load, wire two 8
Ω
speakers in parallel
with Left + and Right – (Diagram A) or use
a single 4
Ω
speaker. For a four-channel
amplifier, follow the speaker output con-
nection diagram for bridging as shown on
the back of your amplifier, and wire two 8
Ω
speakers in parallel to achieve a 4
Ω
load
or use a single 4
Ω
speaker per channel.
If you have any questions or concerns,
please contact your local authorized
Pioneer dealer or call Pioneer customer
service.
WARNING
• Always use the special red battery and ground
wire [RD-223], which is 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.
• DO NOT allow amplifier to come into contact
with liquids due to, for example, the location
where the amplifier is installed. Electrical shock
could result. Also, amplifier and speaker damage,
smoke, and overheating could result from contact
with liquids. In addition, the amplifier surface and
the surface of any attached speakers could become
hot to the touch and minor burns could result.

Gain Control
If the sound level is too low, even when the volume of the car stereo used along with this
power amplifier is turned up, turn gain control clockwise. If the sound distorts when the vol-
ume is turned up, turn the gain control counter-clockwise.
• 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.
• If you hear too much noise when using the speaker input terminals, turn the gain control
counter-clockwise.
Power Indicator
The power indicator
lights when the power is
switched on.
LPF (Low-Pass Filter)/HPF (High-Pass Filter) Select Switch

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 Hz to 120 Hz.
Terminal Cover
Before setting up the unit, unfasten the screws
with a 4 mm hexagonal wrench (not supplied)
and remove the terminal cover.
Bass Boost Control
You can select a bass boost level
from 0, 6, 9 and 12 dB.
For instruction of connecting the
bass boost remote control to the
amplifier, see the “Connection
Diagram” section.
BFC (Beat Frequency Control)
Switch
BFC switch is on the bottom of the
unit. If you hear a beat while listening
to an AM broadcast with your car
stereo, change the BFC switch using
a small standard tip screwdriver.
Input Switch
It is possible to input from a car stereo external output (subwoofer
output) or a car stereo speaker output. When using an external output (subwoofer output),
slide the switch to the left. For connection instructions, see the “Connection Diagram” sec-
tion. When using a speaker output, slide the switch to the right. In this case, it is necessary to
use the supplied speaker input wire with RCA pin cord. For details, see the “Using the
Speaker Input” section.
