PRECAUTIONS
•
This unit is designed for negative ground 12-14.50 VoIts (DC) operation only
•
Use speakers with an impedance of 2 or 4 Ohms (
4 to 8 Ohm when used as
bridged amplifier
)
•
Avoid installing the unit where:
•
It would be subject to high temperatures, such as from direct sunlight or hot
air from the heater.
•
It would be exposed to rain or moisture.
•
It would be subject to dust or dirt.
•
If your car is parked in direct sunlight and there is a considerable rise in
temperature inside the car, allow the unit to cool off before operation.
•
When installing the unit horizontally, be sure not to cover the heatsink fins
with the floor carpet.
•
If this unit is placed too close to the car radio, an interference may occur in this
case, separate the amplifier from the car radio.
•
This power amplifier employs a protection circuit to protect the transistors and
speakers if the amplifier malfunctions.
•
Do not attempt to test the protection circuits by covering the heatsink or
connecting improper loads.
•
Do not use the unit with a weak auto battery as its optimum performance
depends on a normal battery supply voltage.
•
For safety reasons, keep the volume of your car audio system moderate so that
you can still hear normal traffic sounds outside your car.
FUSE REPLACEMENT
If the fuse blows, check the power connection and replace the fuse. If the fuse
blows again after replacement, there may be an internal malfunction.
In this case, consult your dealer.
WARNING:
Use the specified amperage fuse. Use of a higher amperage fuse
may cause serious damage.
PROTECTION CIRCUIT
This amplifier is provided with a protection circuit which operates in the
following cases when:
•
the unit is overheated.
•
the speaker terminals are short circuited.
