Setting the unit

What's what

Front side

Rear side

To adjust the switch, use a flathead screwdri-

ver if needed.

LPF (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.

GAIN (gain) control

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 con-

trols to 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 max.

output of 4 V or more, adjust level to

match that of the car stereo output.

•

If you hear too much noise when using

the speaker input terminals, turn the

gain control to higher level.

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.

If amplifier gain is raised improperly, this will

simply increase distortion, with little increase

in power.
