Gain Control
Adjusting the gain controls A and B will
help match the output of the car stereo
to the Pioneer amplifier
. Normally
the gain controls to the NORMAL
position. If the output is low
the volume of the car stereo is turned
up, turn these controls clockwise. If
there is distortion when the volume 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.
