Level(V) Control
The amplifier is capable of operating from audio signal sources supplying a wide range of input levels. The Level (V) control should initially be set to the mid-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 to 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.
OPERATION
After initial set-up, the amplifier should not require any further adjustment unless there is a change in the car stereo or speaker system with which it is used.

1 Power Indicator
The POWER LED functions as both a power and a warning indicator. When the amplifier is off, the indicator is inactive and appears white. When power is applied to the amplifier, the LED indicator illuminates green, provided no malfunction is present, thus signifying the amplifier is operating normally. When the LED illuminates red, the built-in self-protection circuits have been activated and have shut down operation of the amplifier. The protection circuits may be triggered by the temperature of the unit rising above a safe level or by an overload condition. If activated by a rise in temperature, the unit will resume operation after cooling off to a normal operating range. If activated by an overload condition, the source of the overload must be found and corrected to resume normal operation of the amplifier. Most overload conditions are-8-
