GAIN (gain) control
If output remains low, even when the car
stereo volume is turned up, turn controls to
lower level. If distortion occurs when the car
stereo volume is turned up, turn these con-
trols to higher level.
!
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 max.
output of 4 V or more, adjust level to
match that of the car stereo output.
!
If you hear too much noise when using
the speaker input terminals, turn the
gain control to higher level.

Setting gain properly
!
Protective function included to prevent
malfunction of the unit and/or speakers
due to excessive output, improper use or
improper connection.
!
When outputting high volume sound etc.,
this function cuts off the output for a few
seconds as a normal function, but output
is restored when the volume of the head
unit is turned down.
!
A cut in sound output may indicate impro-
per setting of the gain control. To ensure
continuous sound output with the head
unit at a high volume, set amplifier gain
control to a level appropriate for the preout
maximum output level of the head unit, so
that volume can remain unchanged and to
control excess output.
