increase the output from the system. If, however, there
is still output from the amplifier when the car stereo
volume control is at its minimum setting, or the output
level increases too fast with a small rotation of the volume
control, adjust the Level control to decrease the output
from the system. Once the correct setting is found, these
controls should not require any further adjustment.

Fuse
The circuitry of the amplifier is protected from damage by
an automotive-type fast-blow fuse. If fuse replacement is
necessary, use only fuses of the same ampere rating as
originally supplied with the unit. The use of fuses with
incorrect ratings may cause serious damage to the
amplifier. If fuses blow consistently, carefully check all
electrical connections to the unit.

Power Indicator LED
The Power Indicator LED will light to indicate that the
unit is connected to the battery and that the Remote

on the amplifier.

Level (Gain) Controls
The amplifier is capable of operating from sources
supplying a wide range of input levels. The Level
control should initially be set to the mid-rotation position.
If it is found that there is not enough output even when the
volume control on the car stereo is at its maximum setting,
adjust the Level control of the respective channels to
