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.

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 LPF. This eliminates high range

frequency and outputs low range fre-

quency.

•

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-

quency range.

INPUT SELECT {input select) switch

Select

2CH

for two-channel input and

4CH

for four-channel input.

POWER/PROTECT indicator

The power indicator lights up to indicate

power ON.

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.

If amplifier gain is raised improperly, this will

simply increase distortion, with little increase

in power.
