1. Connecting the Speakers

Setting the unit

2 FREQ (cut off frequency) control

Cut off frequency selectable from 40 Hz to

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

3 BASS BOOST (bass boost level control)

switch

You can select a bass boost level from 0 dB,

6 dB and 12 dB.

4 GAIN (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.

5 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.
