OPERATION

GND(-)=GROUND CONNECTION
Connect the GND terminal to the chassis ground of your car and take care of best
electric and mechanic contact. In doing so, drill a hole in to the
the amplifier then remove color, dirt or any other substance from the ground point.
After that fasten the cable end with added ring terminal by using a screw. Ensure
that the ground connection is as short as possible and that the cable diameter is
sufficient ( min 4 mm" ). Route the ground
equipment parts. like equalizer. active crossover network or other amplifiers, to
the same ground point.
+12V=POWER SUPPLY
Connect the +12V terminal to the positive pole of the battery with
and add a fuse in to the power cable in a distance of not more then 30 cm from the
battery. The lead cables's diameter should be at least 4 mm' for a length of 3m
and 6 mm" for a length of 6m.
REM(ON/OFF)REMOTE CONTROL
Connect the REM terminal to the automatic antenna connector of your car radio.
Now when turning on and off your car radio. the amplifier automatically switches
ON and OFF. A cable diameter of 0.5mm is sufficient.
FUSE
The amplifier is equipped with a plug-in auto fuse protecting the set against fault
conditions. Do not use a fuse with a higher value and never bridge the fuse over,
as this may lead to irreparability damage so that ant any claim for
denied.
TROUBLE SHOOTING
No Function:
The connection cable is not connected correctly ( = terminal BATT/GND /REM).
Ensure that all connections and mechanic contact and that the jacket has been
removed. The fuse is defective-pay attention to the correct value of a new fuse!
No Sound:
Speaker cable or speaker plug are not connected correctly.
No Sound /Red LED Protection Shines:
The plus and minus wires of the speaker cable have contact, thus eliminate the
short circuit. If you use a 2 Ohm speaker in stereo mode, a 4 Ohm speaker in
bridge mode or tri-mode and the se is overloaded, then turn the gain control to
"min " until the operation is free of trouble.
Poor Sound Quality ( Distortions ):
The speakers are overloaded, therefore turn down the volume level and check
the volume control positions.
No Stereo Sound And A Weak Bass:
Speaker cables (+) and (-) are mixed up, unit wired out of phase.

PRECAUTIONS
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. a
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 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.
Do not attempt to test the protection
