OPERATION
GND(-)=GROUND CONNECTION
Connect the GNDterminal to thechassis ground ofyour car andtake care ofbest
electric and mechaniccontact. In doingso, drill ahole in tothe car chassisnear
the amplifier thenremove color,dirt or anyother substance fromthe ground point.
After that fastenthe cable endwith added ringterminal by usinga screw. Ensure
that the groundconnection is asshort as possibleand that thecable diameter is
sufficient ( min4 mm" ).Route the ground cables from the radio and allother
equipment parts. likeequalizer. active crossover network orother amplifiers, to
the same groundpoint.
+12V=POWER SUPPLY
Connect the +12Vterminal to thepositive pole ofthe battery with a lead cable
and add afuse in tothe power cablein a distanceof not morethen 30 cmfrom the
battery. The lead cables'sdiameter should beat least 4mm' for alength of 3m
and 6 mm"for a lengthof 6m.
REM(ON/OFF)REMOTE CONTROL
Connect the REMterminal to theautomatic antenna connectorof your car radio.
Now when turningon and off your carradio. the amplifierautomatically switches
ON and OFF. Acable diameter of0.5mm is sufficient.
FUSE
The amplifier isequipped with aplug-in auto fuseprotecting the setagainst fault
conditions. Do notuse a fusewith a highervalue and neverbridge the fuseover,
as this maylead to irreparabilitydamage so thatant any claim for warranty is
denied.
No Function:
The connection cableis not connectedcorrectly ( =terminal BATT/GND /REM).
Ensure that all connections and mechaniccontact and that the jacket has been
removed. The fuseis defective-pay attentionto the correct value of anew fuse!
No Sound:
Speaker cable orspeaker plug arenot connected correctly.
No Sound /RedLED Protection Shines:
The plus andminus wires ofthe speaker cablehave contact, thuseliminate the
short circuit. Ifyou use a 2 Ohm speakerin stereo mode, a 4 Ohm speaker in
bridge mode or tri-mode and these is overloaded, thenturn the gaincontrol to
"min " untilthe operation isfree of trouble.
Poor Sound Quality( Distortions ):
The speakers areoverloaded, therefore turn down the volumelevel and check
the volume controlpositions.
No Stereo SoundAndA WeakBass:
Speaker cables (+)and (-) aremixed up, unitwired out ofphase.

TROUBLE SHOOTING
PRECAUTIONS
FUSE REPLACEMENT
If the fuseblows, check thepower connection andreplace the fuse. If the fuse
blows again afterreplacement, there maybe an internalmalfunction. In thiscase,
consult your dealer.
WARNING:
Use the specifiedamperage fuse. Useof a higheramperage fuse maycause
serious damage.
PROTECTION CIRCUIT:
This amplifier isprovided with aprotection circuit whichoperates in thefollowing
cases when:
the unit isoverheated.
the speaker terminalsare short circuited.
This unit isdesigned for negativeground 12V DCoperation only.
Use speakers withan impedance of2 or 4Ohms (2 to 4Ohm when usedas
bridging amplifier)
Avoid installingthe unit where:
-It would besubject to hightemperatures, such asfrom direct sunlightor hot air
from the heater.
-It would beexposed to rainor moisture.
-It would besubject to dustor dirt.
If your caris parked indirect sunlight andthere is aconsiderable rise in
temperature inside thecar, allowthe unit tocool offbefore operation.
When installing theunit horizontally, be surenot to coverthe heatsink fins with
the floor carpet.
If this unitis placed tooclose to thecar radio, aninterference may occur. In this
case, separate theamplifier from thecar radio.
This power amplifieremploys a protectioncircuit to protectthe transistors and
speakers if theamplifier m lfunctions. Do notattempt to test the protection
circuits by coveringthe heatsink orconnecting improper loads.
Do not usethe unit with a weak autobattery as itsoptimum performance
depends on anormal battery supplyvoltage.
For safety reasons,keep the volumeof your caraudio system moderateso that
you can stillhear normal traffic sounds outsideyour car.
