To adjust the switch, use a flathead screwdri-

ver if needed.

1 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.

2 GAIN (gain) control

Adjusting gain controls CHANNEL A (chan-

nel A) and CHANNEL B (channel B) helps

align the car stereo output to the Pioneer

amplifier. Default setting is the NORMAL

position.

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.

! 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 HIGH posi-

tion.

3 INPUT SELECT (input select) switch

Select 2CH for two-channel input and 4CH

for four–channel input.

! You can select input select only for con-

nections when using the RCA input jack.

For connections when using the speaker

input wire, 4CH will be used automati-

cally no matter which switch setting is

selected.

4 FREQ (cut off frequency) control

Cut off frequency selectable from 40 Hz to

500 Hz if the LPF/HPF select switch is set to

LPF or HPF.

! You can select cut off frequency only for

CHANNEL B.

5 BASS BOOST (bass boost level control)

switch

You can select a bass boost level from 0 dB

to 12 dB.
