POWER SUPPLY AND TURN-ON-CONNECTION

INTERCONNECTION ATTENTION: Before you start with the installation, disconnect the ground connection from the vehicle’s battery in order to prevent short circuits. Thepowerwiringwhichisusuallyinstalledinon-boardcarnetworksisnotsufcientforapoweramplier‘s demands.MakesurethatthepowerwirestoGNDandtothe+12Vterminalhasbeensufcientlyspecied.A cable crosssection 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. Thenconnect the+12 Vterminal oftheamplier withthe batteryby usinganappropriate cableincluding an 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 accomplished. 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.10

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.

SIGNAL OUTPUTS TO CONNECT ADDITIONAL AMPLIFIERS

The input signal on the LINE INPUT jacks (Fig. 1,2) will be routed in stereo to the output jacks LINE OUTPUT (Fig.1,1).ThustheLINEOUTPUTjackallowstheconnectionofaadditionalamplier.

Now turn INPUT LEVEL clockwise until you hear some distortion. Then turn back the INPUT LEVEL slightly until you hear a cleaner sound.

VARIABLE SUBSONIC FILTER

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 LOW PASS controller (Fig. 1,6). Otherwise no sound will be hearable.

Set the desired cross-over frequency by using the controller LOW PASS (Fig. 1,6). Thus to that only the fre- quenciesbelowthechosencross-overfrequencywillbeampliedandthesubwooferplaysmoreprecisedand efcient.

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!

VARIABLE PHASE SHIFT

The PHASE SHIFT controller (Fig. 1,4) allows to set the phase between 0°and 180° to match the run time of the output signal with the vehicle’s interior acoustic.11 FIGURES (P. 28-30) CONNECTIONS AND CONTROLLERS (FIG. 1) (1) LINEOUTPUTaudiosignaloutputstorunadditionalampliers (2) LINE INPUT audio signal inputs (3) INPUT LEVEL controller (4) PHASE SHIFT controller (5) SUBSONICltercontroller (6) LOWPASSltercontroller (7) BASS BOOST controller (8) Connector for the included bass level remote controller (9) Power-/Protection-LED POWER SUPPLY AND TURN ON CONNECTION (FIG. 2) (1) GND terminal for the ground (2) REM terminal for the turn on connection (3) +12 V terminal for the positive-connection of the battery (4) Vehicle’s battery (5) In-Line Fuse (not included in the scope of delivery) (6) Turn on wire from the headunit or the electrical antenna (7) Fuse 1-CHANNEL OPERATION MONO 2 SUBWOOFERS (FIG. 4) Ifyouwanttoruntheamplierwiththe2lineoutputchannelsfromtheheadunittodrivetwosubwoofers, connect the following setup: (1) To the headunit, line output rear left or subwoofer output (2) To the headunit, line output rear right or subwoofer output (3) Bass level remote controller (4)Subwoofer1(2-8Ω) (5) Subwoofer2(2-8Ω) 1-CHANNEL OPERATION MONO 1 SUBWOOFER (FIG. 3) Ifyouwanttoruntheamplierwiththe2lineoutputchannelsfromtheheadunittodriveasubwoofer,connect the following setup: (1) To the headunit, line output left or subwoofer output (2) To the headunit, line output right or subwoofer output (3) Bass level remote controller (4)Subwoofer(1-8Ω) IMPORTANT!

Procedure 1: CheckAmplierforproperconnections. Verify that POWER/PROTECTION LED lits up green. If If this is the 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 lits up red. 1. If the PROTECT lits up red, this 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 5: CheckAmplierifyouexperienceexcessEngineNoise.

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.
