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 blar-
ing or distortion and, most importantly, with-
out 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 dis-
tortion.
!Once you have established a comfortable
sound level, set the dial and leave it there.
BE SURE TO OBSERVE THE FOLLOWING
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.

installing the amplifier
WARNING
!This product contains chemicals known to the
State of California and other governmental en-
tities tocause cancer and birth defects or
other reproductive harm. Wash hands after
handling.
!Slots and openings in the cabinet are provided
for ventilation to ensure reliable operation of
the product, and to protect it from overheat-
ing. To prevent fire hazard, the openings
should never be blocked or covered with items
(such as papers, floor mat, cloths).
!This unit is for vehicles with a 12 V battery and
negative grounding. Before installing in re-
creational vehicles, trucks or buses, check the
battery voltage.
!When installing this unit, make sure to con-
nect the ground wire first. Ensure that the
ground wire is properly connected to metal
parts of the car s body. The ground wire of the
one of this unit must be connected to the car
separately with different screws. If the screw
for the ground wire loosens or falls out, it
could result in fire, generation of smoke or
malfunction.
!Be sure to install the fuse to the battery wire.
!Always use a fuse of the rating prescribed.
The use of an improper fuse could result in
overheating and smoke, damage to the pro-
duct and injury, including burns.
!Check the connections of the power supply
and speakers if the fuse of the separately sold
battery wire or the amplifier fuse blows. Deter-
mine and resolve the cause, then replace the
fuse with and identical equivalent.
!Always install the amplifier on a flat surface.
Do not install the amplifier on a surface that
is not flat or on a surface with a protrusion.
Doing so could result in malfunction.
!When installing the amplifier, do not allow
parts such as extra screws to get caught be-
tween the amplifier and the automobile.
Doing so could cause malfunction.
!Do not allow this unit to come into contact
with liquids. Electrical shock could result.
Also, damage to this unit, smoke, and over-
heating could result from contact with liquids.
The surfaces of the amplifier and any attached
speakers may also heat up and cause minor
burns.
!In the event of any abnormality, the power
supply to the amplifier is cut off to prevent
equipment malfunction. If this occurs, switch
the system power off and check the power
supply and speaker connections. If you are un-
able to determine the cause, please contact
your dealer.
!Always disconnect the negative terminal of*
the battery beforehand to avoid the risk of
electric shock or short circuit during installa-
tion.
!Do not attempt to disassemble or modify this
unit. Doing so may result in fire, electric
shock or other malfunction.
CAUTION
!Always keep the volume low enough to hear
outside sounds.
!Extended use of the car stereo while the en-
gine is at rest or idling may exhaust the bat-
tery.
!This product is evaluated in moderate and tro-
pical climate condition under the Audio, video
and similar electronic apparatus - Safety re-
quirements, IEC 60065.
!The graphical symbol placed on the
product means direct current.

1 BASS BOOST REMOTE (bass boost level
remote control) jack
By connecting the Bass boost level remote
control to the jack on the main unit, you will
be able to select a bass boost level from
0 dB to 18 dB.
! Bass boost level setting applies only to
CHANNEL B (channel B) output.
! For instruction of connecting the bass
boost remote control to the amplifier, see
the .Connection diagram
2 FREQ (cut off frequency) control
Cut off frequency selectable from 40 Hz to
500 Hz if the / select switch is set toLPF HPF
LPF HPFor .
3 GAIN (gain) control
Adjusting gain controls (chan-CHANNEL A
nel A) and (channel B) helpsCHANNEL B
align the car stereo output to the Pioneer
amplifier. Default setting is the NORMAL
position.
En
Before you start Setting the unit
If the output remains low, even when the car
stereo volume is turned up, turn the con-
trols to a lower level. If distortion occurs
when the car stereo volume is turned up,
turn these controls to a 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 maxi-
mum 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 position.H
4 LPF (low-pass filter)/HPF (high-pass fil-
ter) select switch
Switch the settings based on the connected
speaker.
!When the Subwoofer is connected:
Select . This eliminates high rangeLPF
frequency and outputs low range fre-
quency.
!When the full range speaker is con-
nected:
Select or . eliminates lowHPF OFF HPF
range frequency and output high range
frequency. outputs the entire fre-OFF
quency range.
5 INPUT SELECT (input select) switch
Select for two-channel input and2CH 4CH
for four channel input.
6 POWER/PROTECT indicator
The power indicator lights up to indicate
power ON.
!If something is not normal, the indicator
turns red.
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.
Gain control of this unit
Preout level: 2 V (Standard: 500 mV)
Preout level: 4 V
Above illustration shows gain set-NORMAL
ting.
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.
En
Setting the unit
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.

WARNING
! Secure the wiring with cable clamps or adhe-
sive tape. To protect the wiring, wrap sections
in contact with metal parts in adhesive tape.
! Never cut the insulation of the power supply
to feed power to other equipment. Current ca-
pacity of the wire is limited.
CAUTION
! Never shorten any wires, the protection circuit
may malfunction.
! Never wire the speaker negative cable directly
to ground.
! Never band together multiple speaker s nega-
tive cables.
! If the system remote control wire of the ampli-
fier is connected to the power terminal via the
ignition switch (12 V DC), the amplifier will re-
main on with the ignition whether the car
stereo is on or off, which may exhaust battery
if the engine is at rest or idling.
! Install and route the separately sold battery
wire as far as possible from the speaker wires.
Install and route the separately sold battery
wire, ground wire, speaker wires and the am-
plifier as far away as possible from the anten-
na, antenna cable and tuner.
