Setting the unit

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.

3 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 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 HIGH posi-

tion.

cally no matter which switch setting is
