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 car chassis near 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 , Route the ground cables from the radio and all other equipment parts. like
equalizer. active crossover network or other amplifiers, to the same ground point.
+12 V = POWER SUPPLY
Connect the +12V terminal to the positive pole of the battery with a lead cable and add a fuse
into the power cable in a distance of not more then 30 cm from the battery. The lead cable's
diameter should be at least 8 mm' for a proper length .
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
2
diameter of 0.5 mm 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 warranty is denied.
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.
LED Protection Shines :
If you use a 1 Ohm speaker , the set 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
GAIN control positions.
HOW TO PROCEED IN CASE OF FAULTS
OPERATION
All cables are sources of interference or gather them. The power cable and Cinch/RCA
audio cable are very prone to interference; the remote cables are less prone. There is
often interference caused by the generator (piping), ignition (cracking) or other car
electronic parts. Most of these problems can be eliminated by correct and careful
cabling. In doing so, there are the following guidelines:
Use only a screenedio audio cable for the wiring between "Line input" of the amplifier
and RCA or DIN output of the radio.
Lay the signal, speaker and power cables separately with enough distance from
another and also from each other car cable. If not possible, you can lay the circuit and
ground cable together with the serial cables. Audio and speaker cable should be as far
away from these as possible. The REM cable to the automatic antenna output of the
radio can be laid together with the signal cables.
Avoid ground loops by laying the ground wiring of all components to a center point in a
star-like way. You can find the best central point in measuring the voltage directly at the
battery. Now compare this voltage value with the chosen ground point and the (+)
terminal of the amplifier, If the measured voltage in only less different, you've found the
correct central. Otherwise you have to look for another point. You should measure
with the ignition being switched on and additionally switched on consumers (rear
window heating and light).
If there are pickups from external electrical sources into the speaker cables, divide the
core leads and twist them together.
If there are noises from the car electrics, add an interference suppression choke into
the power wiring.
If there are huming noises, uses, use thicker ground cables or add further ground
cables to the chassis.
To reduce contact resistance and bad and loose contacts, please tin the cable ends or
use multi core cable ends, spade terminals or others. Chrome Plated spade terminal
are free of corrosion and have the lowest contact resistance.
Should all these meaures be without any success, the use of a ground loop isolator may
solve the problem.
INTERFERENCE
WARNING:
(1)Don't short the SPEAKER OUT and terminals or connection wires, that will
damage the amplifier.
(2)If you want to use your radio ,suggest you turn off this amplifier ,prevent to disturb
your radio.
