IMPORTANT NOTES PRIOR TO INSTALLATION

- This device is only suited for a 12 volt system with negative ground. - Theradiatedheatwhileoperationrequiressufcientaircirculationattheplaceofinstallation.Itis veryimportantthattheheatsinknsdonothavecontactwithanymetalpartsoranysurfaceswhich couldimpairaircirculation.Theampliermaynotbeinstalledinsmallclosedlocationorspaces without air circulation (e.g. spare wheel recess or below the vehicle carpeting). We recommend the installationinthevehicle’strunk.Ensuresufcientprotectionagainstvibrations,dustanddirt. - Ensurethattheinputandoutputcablesaresufcientlyseparatedfromthepowersupplycables. Otherwise interferences may occur. - Ensure the accessibility of the fuse and the operating elements after installation. - Thereliabilityandperformanceoftheamplierdependsonthequalityofinstallation.Preferably consult an expert to install the system, particularly if you want to install several loudspeakers.

POWER SUPPLY AND TURN-ON-CONNECTION

INTERCONNECTION ATTENTION: Before you start with the installation, disconnect the ground connection from the ve- hicle’s battery in order to prevent short circuits. Thepowerwiringwhichisusuallyinstalledinon-boardcarnetworksisnotsufcientforapoweramplier‘s demands.MakesurethatthepowerwirestoGNDandtothe+12Vterminalhasbeensufcientlyspecied.A cable-cross section of at least 10 mm

mustbeusedtoconnectthebatterytotheamplier‘sterminals. FirstconnecttheGNDterminaloftheampliertoanappropriategroundconnectionatthechassis.Toensurea good connection, residue dirt and dust from the connection point. A loose connection may cause malfunctions or interferences noise and distortion. Thenconnectthe+12Vterminaloftheamplierwiththebatterybyusinganappropriatecableincludingan in-line fuse. This fuse should be located very close to the battery; for safety reasons not more than 30 cm away. Only insert the fuse when the installation, including the connection of the loudspeakers, has been ac- complished. Thenconnecttheremoteturn-on-wirefromtheheadunitwiththeamplier‘sREMOTEterminal.Acablewitha cross section of 0.5 mm

is adequate. LOUDSPEAKER CONNECTIONS - The total impedance must not be lower than 1 ohm. - Never connect loudspeaker cables with the ground of the chassis or the +12 V supply voltage. Iftheamplierisoperatedwithatoolowimpedanceorincorrectlyused,theentiresoundsystem may be damaged. This means a warranty void in such cases.

WheninstallingtheaudiocablesbetweentheRCAoutputsoftheheadunitandtheRCAinputsoftheamplier, the audio and power supply cables should, if possible, not be routed along the same side of the vehicle. We recommend a separated installation, e.g. routing the power cable through the cable channel on the left side and the audio cables through the cable channel of the vehicle on the right side or vice versa. This prevents interferences due to crosstalk into the audio signal.10 INPUT SENSITIVITY OPERATING ELEMENTS TurntheGAIN(Fig.1,3)controlleroftheampliertotheMINposition.Thenturnthevolumecontrollerofthe head unit to 80 - 90% of its full setting. Now turn GAIN clockwise until you hear some distortion. Then turn back the GAIN slightly until you hear a cleaner sound.

VARIABLE SUBSONIC FILTER

WiththeSUBSONICcontroller(Fig.1,5)youcanadjustthelowercrossoverfrequency,toltertheverylow frequencies to relieve the subwoofer or to generate a bandpass signal. If you don’t want to use this function, turn the controller (Fig. 1,5) to the very left to the 10 Hz position. NOTE: The adjusted value of the SUB SONIC (Fig. 1,5) should not be higher than the adjusted value of the LPF controller (Fig. 1,6). Otherwise no sound will be audible.

VARIABLE LOW PASS FILTER

Set the desired crossover frequency by using the controller LPF (Fig. 1,6). Thus to that only the frequencies belowthechosencrossoverfrequencywillbeampliedandthesubwooferplaysmorepreciselyandefcient.

BASS LEVEL REMOTE CONTROLLER

With the included bass level cable remote controller you are able to adjust the bass level e.g. out of the driver’s seat.

With the bass boost controller (Fig. 1,7) you are able to adjust the bass level from 0 - 12 dB. Attention: Use the BASS BOOST wisely!

PHASE SHIFT CONTROLLER

The PHASE SHIFT controller (Fig. 1,4) allows to adjust the phase between 0° and 180° to match the output signal with the vehicle’s interior acoustic.

Procedure 1: CheckAmplierforproperconnections. POWER/PROTECTION LED lights up green. In this case skip to Step 3, if not continue.

1. Check in-line fuse on battery positive cable. Replace if necessary.

2.Checkfuse(s)onamplier.Replaceifnecessary.

3. Verify that Ground connection is connected to clean metal on the vehicle’s chassis. Repair/replace if necessary.

4. Verify there is 9 to 16 Volts present at the positive battery and remote turn-on cable. Verify quality connections for both cables at amplier,stereo,andbattery/fuseholder.Repair/replaceifnecessary. Procedure 2: POWER/PROTECTION LED lights up red. 1. If the LED lights up red it is a sign of a possible short in the speaker connections. Check for proper speaker connections and use an ohm meter to check for possible shorts in the speaker wiring. Too low speaker impedance may also cause PROTECTION tolight.Thiscanalsobeasignofdrivingtheamplieratveryhighpowergainswithoutadequateairowaroundtheamplier.Shut offthesystemandallowampliertocool.Checkthatthevehiclechargingsystemismaintainingpropervoltage.Ifthepreviousitems donotsolvetheproblem,afaultmaybeintheamplier.Inthiscaseyoushouldcontactyourdealer. Procedure 3: CheckAmplierforaudiooutput.

1. Route all signal carrying wires (RCA, Speaker cables) away from power and ground wires.

3. Remove existing ground wires for all electrical components. Reground wires to different locations.

Verify that grounding location is clean, shiny metal free of paint, rust etc.

4. Add secondary ground cable from negative battery terminal to the chassis metal or engine block of vehicle.
