If the output remains low even when the
headunit volume is turned up, turn the
volume to a lower level (clockwise). If dis-
tortion occurs when the headunit volume is
turned up, turn these volumes to a higher
level (counterclockwise).
If using only one input plug, set the gain
volumes for speaker outputs A, B, and C
to the same position.
For use with an RCA equipped stereo
(standard output of 500 mV), set to the
NOR
(normal) position. For use with an
RCA equipped Pioneer stereo with max-
imum output of 4 V or more, adjust level
to match that of the stereo output.
For use with an RCA equipped stereo
with output of 4 V, set to the

Setting gain properly
Protective function included to avoid
malfunction of the unit and/or speakers
due to excessive output, improper use or
improper connection.
When outputting high volume sound etc.,
this function may cut off the output for a
few seconds as a normal function, Output
will be restored when the volume of the
headunit is turned down.
A cut in sound output may indicate
improper setting of the gain volume. To
ensure continuous sound output with the
headunit at a high volume, set the ampli-
fier gain volume to a level appropriate
for the preout maximum output level of
the headunit, so that volume can remain
unchanged and to avoid distortion caused
by signal waveform clipping at the amplifier
input.
Even with correct volume and gain set-
tings, the unit sound may cut out period-
ically. In such cases, please contact an
authorized Pioneer Service Company.

If amplifier gain is raised improperly, this will
simply increase distortion, with little increase
in power.
