1 FREQ (cut off frequency) control
Cut off frequency selectable from 40 Hz to
500 Hz if the HPF select switch is set to HPF.
! You can select cut off frequency only for
CHANNEL A.
2 LPF (low-pass filter)/HPF (high-pass fil-
ter) select switch

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

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.
4 INPUT SELECT (input select) switch

! 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
