SETTING THE CROSSOVER AND BASS BOOST
Fine tune the amplifier's input sensitivity.
Access to the gain sensitivity control for the California
amplifier is located on the side panel. This gain control has
been included to allow adjustment to properly match the
output of the radio. This is one of the most misunderstood
adjustments. By rotating the control in the clockwise
direction, the amplifier's input will become more sensitive and
the music will play louder. This is not a volume control and you will not get more power out of
the amplifier in the maximum position! It may seem to deliver more output, but actually the
system is only playing louder faster as you turn the volume control on the radio. Ideally, to
properly level match the system the goal is to achieve maximum output from the amplifier
without distortion at about 3/4 of the volume control.
To determine if the amplifier's gain is set properly, turn the system on and slowly increase the
volume control. You should be able to use about 3/4 volume before the system gets loud but
not distorting. It is very important when making these adjustments that you do not over drive
the speakers (at point of distortion) this will cause permanent damage to the speakers. If you
are unable to achieve 3/4 volume before distortion you will need to adjust gain control (in this
case you would reduce the gain). The gain controls should be adjusted very slowly. It may help
to have another person to assist you by adjusting the gain controls while you listen for
distortion.
