Before connecting/

installing the amplifier

WARNING

!The use of a special red battery and ground

wire RD-223, available separately, is recom-

mended. Connect the battery wire directly to

the car battery positive terminal +and the

ground wire to the car body.

!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.

!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.

To adjust the switch, use a flathead screwdri-

ver if needed.

1LPF (low-pass filter) switch

Switch the settings based on the connected

speaker.

!When the Subwoofer is connected:

Select ON. This eliminates high range

frequency and outputs low range fre-

quency.

!When the full range speaker is con-

nected:

Select OFF.OFF outputs the entire fre-

quency range.

2FREQ (cut off frequency) control

Cut off frequency selectable from 40 Hz to

500 Hz if the LPF select switch is set to ON.

3BASS BOOST (bass boost level control)

switch

You can select a bass boost level from 0 dB,

6 dB and 12 dB.

4GAIN (gain) control

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.

!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 HIGH posi-

tion.

!If you hear too much noise when using

the speaker input terminals, turn the

gain control to higher level.

5Power indicator

The power indicator lights up to indicate

power ON.

Setting the unit

5707000011340V <5>

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: 4 V

Preout level: 2 V

(Standard: 500 mV)

Above illustration shows NORMAL gain set-

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.

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.

!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.

About bridged mode

!Do not install or use this amplifier by wiring

speakers rated at 4 W(or lower) in parallel to

achieve a 2 W(or lower) bridged mode (Dia-

gram B).

Amplifier damage, smoke, and overheating

could result from improper bridging. The am-

plifier surface could also become hot to the

touch and minor burns could result.

To properly install or use a bridged mode and

achieve a 4 Wload, wire two 8 Wspeakers in

parallel with Left +and Right *(Diagram A)

or use a single 4 Wspeaker.

In addition, refer to the speaker instruction

manual for information on the correct connec-

tion procedure.

!For any further enquiries, contact your local

authorized Pioneer dealer or customer

service.
