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 overheat-
ing 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
load, wire two 8 speakers in paral-
lel with Left + and Right - (Diagram A) or
use a single 4
speaker. For a four-chan-
nel amplifier, follow the speaker output
connection diagram for bridging as shown
on the back of your amplifier, and wire
two 8
speakers in parallel to achieve a 4
load or use a single 4 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.

Setting the Unit
ENG/MASTER 96
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.
· If you hear too much noise when using the
speaker input terminals, turn the gain
control counter-clockwise.
Input Select Switch
For two-channel input, slide this switch
to the left. For four-channel input, slide
this switch to the right.
