Setting the Unit
Gain Control and Bass Level
Control
Adjusting the gain controls A and B and
the bass level control (CH SUB) will
help match the output of the car stereo
to the Pioneer amplifier. Normally, set
these controls to the "NORMAL
(NORM.)" position. If the output is low,
even when the volume of the car stereo
is turned up, turn these controls clock-
wise. If there is distortion when the vol-
ume of the car stereo is turned up, turn
these controls counter-clockwise.
• If you only use one input plug, set the gain
controls for speaker outputs A and B to the
same position.
• When using with an RCA equipped car
stereo (standard output of 500 mV), set to
the NORMAL position. When using with
an RCA equipped Pioneer car stereo with
max. output of 4 V or more, adjust level to
match the car stereo output level.
• When you want to boost bass, turn the bass
level control clockwise.
BFC (Beat Frequency Control) Switch
If you hear a beat while listening to an
AM broadcast with your car stereo,
change the BFC switch using a small
standard tip screwdriver.
Cut Off Frequency Control
You can select a cut off frequency from
40 to 240 Hz.

power is switched on.
