Pioneer amplifier. Normally, set the gain
controls to the NORMAL position. If the
output is low, even when the volume of the
car stereo is turned up, turn these controls
clockwise. 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.

Cut Off Frequency Control
If the LPF/HPF select switch is set to LPF
or HPF, you can select a cut off frequency
from 40 to 120 Hz.
LPF (Low-Pass Filter)/HPF (High-Pass Filter) Select Switch
Set the LPF/HPF select switch as follows according to the type of speaker that is connected
to the speaker output connector and the car stereo system:
LPF/HPF Select Audio frequency range Speaker Remarks

HPF (Right) * 40 to 120 Hz — Full range Use if you want to cut the
very low frequency range*
because it is not necessary
for the speakers you are
using.
