The Safety of Your Ears is in
Your Hands
Get the most out of your equipment by playing
it at a safe level—a level that lets the sound
come through clearly without annoying blaring or distortion and, most importantly, without affecting your sensitive hearing. Sound
can be deceiving. Over time, your hearing
“comfort level” adapts to higher volumes of
sound, so what sounds “normal” can actually
be loud and harmful to your hearing. Guard
against this by setting your equipment at a
safe level BEFORE your hearing adapts.
ESTABLISH A SAFE LEVEL:
! Set your volume control at a low setting.
! Slowly increase the sound until you can
hear it comfortably and clearly, without distortion.
! Once you have established a comfortable
sound level, set the dial and leave it there.
BE SURE TO OBSERVE THE FOLLOWING
English
GUIDELINES:
! Do not turn up the volume so high that you
can’t hear what’s around you.
! Use caution or temporarily discontinue use
in potentially hazardous situations.
! Do not use headphones while operating a
motorized vehicle; the use of headphones
may create a traffic hazard and is illegal in
many areas.

To adjust the switch, use a flathead screwdriver if needed.
1 LPF (low-pass filter)/HPF (high-pass filter) select switch
Switch the settings based on the connected
speaker.
! When the Subwoofer is connected:
Select LPF. This eliminates high range
frequency and outputs low range frequency.
! When the full range speaker is con-
nected:
Select HPF or OFF. HPF eliminates low
range frequency and output high range
frequency. OFF outputs the entire fre-
English
quency range.
2 GAIN (gain) control
Adjusting gain controls CHANNEL A (channel A) and CHANNEL B (channel B) helps
align the car stereo output to the Pioneer
amplifier. Default setting is the NORMAL
position.
If output remains low, even when the car
stereo volume is turned up, turn controls to
lower level. If distortion occurs when the car
stereo volume is turned up, turn these controls to higher level.
! If using only one input plug, set the gain
controls for speaker outputs A and B to
the same position.
! For use with an RCA equipped car stereo
(standard output of 500 mV), set to the
NORMAL position. For use with an RCA
equipped Pioneer car stereo, with maximum output of 4 V or more, adjust level
to match that of the car stereo output.
! For use with an RCA equipped car stereo
with output of 4 V, set to the HIGH position.
3 INPUT SELECT (input select) switch
Select 2CH for two-channel input and 4CH
for four–channel input.
! You can select input select only for con-
nections when using the RCA input jack.
For connections when using the speaker
input wire, 4CH will be used automatically no matter which switch setting is
selected.
4 FREQ (cut off frequency) control
Cut off frequency selectable from 40 Hz to
500 Hz if the LPF/HPF select switch is set to
LPF or HPF.
! You can select cut off frequency only for
CHANNEL B.

Setting the unit
! Bass boost level setting applies only to
CHANNEL B (channel B) output.
6 Power indicator
The power indicator lights up to indicate
power ON.
Setting gain properly
! Protective function included to prevent
malfunction of the unit and/or speakers
due to excessive output, improper use or
improper connection.
! When outputting high volume sound etc.,
this function cuts off the output for a few
seconds as a normal function, but output
is restored when the volume of the head
unit is turned down.
! A cut in sound output may indicate impro-
per setting of the gain control. To ensure
continuous sound output with the head
unit at a high volume, set amplifier gain
control to a level appropriate for the preout
maximum output level of the head unit, so
that volume can remain unchanged and to
control excess output.
! Despite correct volume and gain settings,
the unit sound still cuts out periodically. In
such cases, please contact the nearest
authorized Pioneer Service Station.
Relationship between amplifier gain
and head unit output power
If amplifier gain is raised improperly, this will
simply increase distortion, with little increase
in power.
Signal waveform when outputting at
high volume using amplifier gain
control
If the signal waveform is distorted due to high
output, even if the amplifier gain is raised, the
output power will change only slightly.

Before installing the amplifier
WARNING
! To ensure proper installation, use the supplied
parts in the manner specified. If any parts
other than those supplied are used, they may
damage internal parts of the amplifier, or become loose causing the amplifier to shut
down.
! Do not install in:
— Places where it could injure the driver or
passengers if the vehicle stops suddenly.
— Places where it may interfere with the dri-
ver, such as on the floor in front of the driver’s seat.
! Install tapping screws in such a way that the
screw tip does not touch any wire. This is important to prevent wires from being cut by vibration of the car, which can result in fire.
! Make sure that wires do not get caught in the
sliding mechanism of the seats or touch the
legs of a person in the vehicle as short-circuit
may result.
! When drilling to install the amplifier, always
confirm no parts are behind the panel and
protect all cables and important equipment
(e.g. fuel/brake lines, wiring) from damage.
CAUTION
! To ensure proper heat dissipation of the ampli-
fier, ensure the following during installation:
— Allow adequate space above the amplifier
for proper ventilation.
— Do not cover the amplifier with a floor mat
or carpet.
! Protection function may activate to protect the
amplifier against overheating due to installation in locations where sufficient heat cannot
be dissipated, continuous use under high-volume conditions, etc. In such cases, the amplifier reduces the power output or shuts
down until it has cooled to a certain designated temperature.
! Place all cables away from hot places, such
as near the heater outlet.
! The optimal installation location differs de-
pending on the car model. Secure the amplifier at a sufficiently rigid location.
! Check all connections and systems before
final installation.
! After installing the amplifier, confirm that the
spare tire, jack and tools can be easily removed.
Example of installation on
the floor mat or chassis
1 Place the amplifier in the desired installation location.
Insert the supplied tapping screws (4 mm ×
18 mm (1/8 in. × 3/4 in.)) into the screw holes
and push on the screws with a screwdriver so
they make an imprint where the installation
holes are to be located.
2 Drill 2.5 mm (1/8 in.) diameter holes at
the imprints either on the carpet or directly
on the chassis.
