PRECAUTIONS
FUSE REPLACEMENT
If the fuse blows, check the power connection and replace the f use. 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.
This unit is designed for negative ground 12V DC operation only.
Use speakers with an impedance of 2 or 4 Ohms ( 2 to 4 Ohm when used as
bridging 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 m lfunctions. 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.
a
After the amplifier has been installed and all connections have been made careful
-lyand securely, turn the radio on so that the amplifier is switched on automatically.
After a short power-on period, the amplifier reaches its full performance.
Now turn up the volume slowly using the volume control of the radio. If there is no
sound or only a distorted replay, switch off the radio immediately, the amplifier will
also switch off automatically, and check if all connections have been made correctly.
POWER=LED POWER INDICATOR
After the orderly connection of the three power terminals, the LED indicator shines
green and goes out with off.
PROTECT =LED PROTECTION INDICATOR
This set is equipped with an overload protection, immediately upon overloading
due to short circuit or much increased temperature the overload protection is
activated and the red LED indicator is shining. Through this the amplifier is
protected against damage. In case of the thermal protection a certain short cooling
time must be allowed after which the amplifier automatically resumes operation.
LEVEL CONTROL
The input level control allows the system to work well within a wide range of output
level. Choose the adjustment in the way that you achieve a sound most possibly
without any distortion. as a guideline the following procedure is recommended:
If you use several amplifier, the adjustment has to be made for each set separately,
tune up the volume of your car radio to 2/3 of the maximum volume.
Now turn the gain control of the amplifier from " Min " to " Max " direction until you
can hear distortions. Then turn the level control a little back to " Min ". The gain
control adjustment is finished now.
Attention! If you use 2 Ohm speakers in stereo mode. Tri-mode or 4 Ohm speakers
in bridge mode and the overload protection is triggered, turn the gain control to
" Min " direction, until the operation is free of trouble.
HIGH PASS AND LOW PASS CONTROLS
This amplifier has controls for making good sound
combination.
