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 a power and warning indicator. The indicator is white when the power to the

amplifier is off. When the indicator is green, the amplifier is operating normally. The LED illuminates red to

indicate that the self-protection circuits have been activated and have shut off 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 operation of the amplifier. Most overload conditions are caused by mis-wiring or operation into

incorrect speaker loads. Re-check all wiring and connections if this situation occurs and correct as necessary.

2 Level (Gain) Control

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 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. Once the correct setting is found, this control should not require

any further adjustment.
