MOUNT THE DEVICE AND OTHER COMPONENTS OF THE SOUND SYSTEM SUFFICIENTLY. Otherwise
the device and components may get loose and act as dangerous objects, which could cause serious harm and
damages in the passenger room.
ENSURE NOT TO DAMAGE COMPONENTS, WIRES AND CABLES OF THE VEHICLE WHEN YOU DRILL
THE MOUNTING HOLES. If you drill the mounting holes for the installation into the vehicle’s chassis, ensure
by any means, not to damage, block or tangent the fuel pipe, the gas tank, other wires or electrical cables.
DO NOT INSTALL AUDIO CABLES AND POWER SUPPLY WIRES TOGETHER. Ensure while installation
not to lead the audio cables between the head unit and the processor together with the power supply wires
on the same side of the vehicle. The best is a areal separated installation in the left and right cable channel of
the vehicle. Therewith a overlap of interferences on the audio signal will be avoided. This stands also for the
equipped bass-remote wire, which should be installed not together with the power supply wires, but rather with
the audio signal cables.
ENSURE THAT CABLES MAY NOT CAUGHT UP IN CLOSE-BY OBJECTS. Install all the wires and cables
like described on the following pages, therewith these may not hinder the driver. Cables and wires which are
installed close-by the steering wheel, gear lever or the brake pedal, may caught up and cause highly danger-
ous situations.
DO NOT SPLICE ELECTRICAL WIRES. The electrical wires should not be bared, to provide power supply to
other devices. Otherwise the load capacity of the wire may get overloaded. Use therefor a appropriate distribu-
tion block. Otherwise re hazard and risk of electric shock consists.
DO NOT USE BOLTS AND SCREW NUTS OF THE BRAKE SYSTEM AS GROUND POINT. Never use for
the installation or the ground point bolts and screw-nuts of the brake system, steering system or other security-
relevant components. Otherwise re hazard consists or the driving safety will be derogated.
ENSURE NOT TO BEND OR SQUEEZE CABLES AND WIRES BY SHARP OBJECTS. Do not install cables

INTERCONNECTION
FUSE
The inserted fuses (2 x 40 A) are protecting the amplier from shorts and capacity overload. If you
need to replace the fuse, make sure to use the same type of fuse with the same rating.
BEFORE CONNECTING
For the professional installation of a sound system, car audio
retail stores offers appropriate wiring kits. Ensure a sufcient
prole section (refer to the table below) and a suitable fuse rat-
ing and the conductivity of the cables when you purchase your
wiring kit. Clean and remove rust-streaked and oxidized areas
on the contact points of the battery and the ground connection.
Make sure that all screws are xed tight after the installation,
because loose connections cause malfunctions, insufcient
power supply or interferences.
POWER
Connect the POWER + terminal with the +12V pole of the vehicle’s battery. Use a suitable cable with
a sufcient cross section (refer to the table below).
Connect the POWER – terminal with a suitable contact ground point on the vehicle’s chassis. The
ground wire must be as short as possible and must be connected to a blank metallic point at the
vehicle’s chassis. Ensure that this ground point has a stable and safe electric connection to the nega-
tive “–”pole of the battery. Check this ground wire from the battery to the ground point if possible and
enforce it if required. Use a ground wire with a sufcient cross section (refer to the table below) and
the same size like the +12V power supply wire.

SYSTEM CONFIGURATION
Before turning on the system, set the head-unit output level to a lower level (approximately
20% of its maximum excursion) to avoid damaging the speakers during calibration.
Check again carefully the conguration of the crossovers , the speakers setup. Wrong type
of crossover or inappropriate parameter may cause permanent damages on the speakers,
especially tweeters without passive crossovers.
WARNING
In order to congure the inputs, amplied speaker outputs and pre-amplied power outputs, EQ and time
delays for the amplier, it must be interfaced with the PC. When you get to this point you must already be
aware of what type of system you intend to set up. In order to avoid complications in preparation, make sure
the following points before you start:
• The type of signals that will be assigned to the inputs (e.g.: front left or center or subwoofer, etc.).
• The speakers in the system (e.g.: 3-way front or sub stereo or 2-way rear, etc.).
• If there are passive crossovers that manage groups of speakers (e.g.: 3-way systems with active
midrange).
• If you intend to use an external mono amplier to drive a subwoofer.
• If you intend to use the amplied outputs of the amplier bridged (BLT mode), thus increasing the power on
the output.
INITIAL SYSTEM START-UP
• Download and save the MUSWAY DSP V3.x software via “www.musway.de/dsp” before connecting the
amplier to your personal computer.
• Install the amplier in your vehicle before you connect a computer to it.
• Turn the ignition key to the ACC or ON position.
• Connect a PC/Laptop with the USB terminal of amplier by using the enclosed USB cable.
• After you have open the DSP software, you can set/adjust all the audio settings on the computer.
• The amplier is on when the logo on the top lights up in orange. After 10 seconds it becomes operative.

TROUBLE SHOOTING
NO FUNCTION / THE POWER LED IS NOT ILLUMINATED
First check the fuse of the routed power cable on the vehicle battery
The fuse is defective
Replace the defective fuse with an equivalent one, never with a higher value.
• The fuse fails again.
In this case there appears to be a short circuit between the fuse and the amplier. To do this, check
the + 12V power cable along its entire length from the battery to the amplier for damage and whether
there is a short circuit to ground, e.g. a contact with the vehicle chassis or the body. If necessary,
replace the defective power cable.
The fuse is apparently okay
Use a standard 12 volt voltmeter to check the voltage between the + 12V connection and the ground
connection on the amplier.
• There is no voltage.
Use the voltmeter to check the fuse, which is located close to the vehicle battery, to see whether there
is voltage between the output and ground.
If there is no voltage there, either the fuse holder or the fuse is defective, although it appears to be
okay. If necessary, replace the fuse holder or fuse.
• There is voltage.
If you operate the amplier with a pre-amplier signal (RCA), you must have laid a remote turn-on
wire from the head unit to the REM terminal of the amplier. The AUTO TURN-ON switch must be in
the OFF position. However, you can test the AUTO TURN-ON switch to SIG. to see if the amplier
then turns on. If so, there is a problem with the control line..
• A remote turn-on wire is connected to the REM terminal at the amplier.
Use the voltmeter to check whether there is voltage between the REM terminal of the amplier and
ground. The head unit must be switched on.
There is no voltage.
• Check the remote turn-on wire from the amplier to the head unit for a short circuit or damage.
If necessary, replace the control line..
There is voltage.
• The amplier is probably malfunctioning or defective. Contact your retailer.
If you operate the amplier with the loudspeaker signals (high level mode), the AUTO TURN-ON
switch must be switched to DC.
• The AUTO TURN-ON switch is in the DC position, but the amplier remains off.
Check the speaker cables from the head unit to the amplier for short circuits or damage. If
necessary, replace the speaker cables or insulate the damaged area.

AMPLIFIER ACTIVATES THE PROTECTIVE CIRCUIT / THE PROTECT LED ILLUMINATES
Check the following steps:
Short circuit on the speaker cables
• First disconnect all speaker cables from the amplier. Use a multimeter to check the ohmic impedance
of each loudspeaker by measuring between its plus and minus lines. With standard loudspeakers the
value uctuates between 3 and 5 ohms. The values for low-resistance subwoofers can be lower.
• The measurement shows a resistance value of less than 0.5 Ohms
Then there is a short circuit. Remove the wiring of the affected loudspeaker at its connections. Now
use the multimeter to check the ohmic impedance directly at the loudspeaker connections by measur-
ing between the plus and minus connections.
The measurement shows a resistance value of more than 0.5 Ohms
• The speaker is ne, so the speaker wire appears to be defective and causing a short circuit.
Replace the defective speaker cable.
The measurement shows a resistance value of less than 0.5 Ohms
• The speaker appears to be defective and is shorting out. Replace the defective speaker.
The load impedance of the loudspeakers or the subwoofer is too low
• Compare the ohmic impedance of the connected loudspeaker or subwoofer with the technical speci-
cations of the amplier. For example, if the amplier is only designed for 2 or 4 ohm operation, no
loudspeaker with less than 2 ohms may be connected.
The cross-section of the power cables is too small
• If the cable cross-section is too small, this leads to an increased ohmic resistance and thus to a volt-
age drop (voltage loss). This indicates that the amplier consumes more power. The increased power
consumption results in a signicantly higher heat development and the amplier switches to thermal
protection mode. Therefore, observe the recommended cable cross-sections in these instructions and, if
necessary, lay power cables with a larger cable cross-section.
The amplier is overheated
• The heat sink of each amplier requires sufcient air circulation to be able to dissipate the heat gener-
ated during operation. If necessary, change the installation position in favor of better cooling of the
amplier or ensure better air circulation at the installation location.
• Turn off the sound system and wait about half an hour for the amplier to cool down again. With very
hot outside temperatures and strong sunlight, enormous heat develops inside the vehicle. The amplier
then activates its thermal protection circuit to prevent damage. After cooling down, the amplier works
properly again.

DAS VON IHNEN ERWORBENE GERÄT IST NUR FÜR DEN BETRIEB AN EINEM 12-V-BORDNETZ EINES
FAHRZEUGS AUSGELEGT. Andernfalls besteht Feuergefahr, die Gefahr eines elektrischen Schlages oder
anderer Verletzungen.
BITTE KEINE BEDIENUNG DES SOUNDSYSTEMS AUSFÜHREN, WELCHE VOM SICHEREN LENKEN
DES FAHRZEUGS ABLENKEN KÖNNTE. Führen Sie keine Bedienungen aus, die Ihre Aufmerksamkeit län-
gere Zeit in Anspruch nehmen. Stoppen Sie besser das Fahrzeug an einer sicheren Stelle am Straßenrand,
bevor Sie solche Bedienungen ausführen. Andernfalls besteht Unfallgefahr.
DIE LAUTSTÄRKE NUR SO HOCH EINSTELLEN, DASS SIE WÄHREND DER FAHRT NOCH AUSSENGE-
RÄUSCHE WAHRNEHMEN KÖNNEN. Hochleistungsaudiosysteme in Fahrzeugen, können den Schallpegel
eines “Live-Konzertes” erzeugen. Dauerhaft extrem lauter Musik ausgesetzt zu sein kann den Verlust des
Hörvermögens oder Hörschäden zur Folge haben. Das Hören von lauter Musik beim Autofahren kann Ihre
Wahrnehmung (Warnsignale) beeinträchtigen. Im Interesse der allgemeinen Sicherheit empfehlen wir das Mu-
sikhören beim Autofahren mit geringer Lautstärke. Andernfalls besteht Unfallgefahr.
LÜFTUNGSÖFFNUNGEN UND KÜHLKÖRPER NICHT ABDECKEN. Andernfalls kann es zu einem Wärme-
stau im Gerät kommen und es besteht Feuergefahr.
DAS GERÄT AUF KEINEN FALL ÖFFNEN. Andernfalls besteht Unfallgefahr, Feuergefahr oder die Gefahr
eines elektrischen Schlages. Das Öffnen des Gerätes hat auch einen Garantieverlust zur Folge.
SICHERUNGEN IMMER DURCH SOLCHE MIT DER RICHTIGEN AMPEREZAHL ERSETZEN. Andernfalls
besteht Feuergefahr oder die Gefahr eines elektrischen Schlages.
DAS GERÄT NICHT WEITERBENUTZEN, WENN EINE FEHLFUNKTION AUFTRITT, DIE NICHT VON IH-
NEN BEHOBEN WERDEN KANN. Beachten Sie dazu den Abschnitt FEHLERBEHEBUNG. Andernfalls kann
es zu Verletzungen oder Schäden am Gerät kommen. Geben Sie das Gerät zu Reparaturzwecken an einen
autorisierten Händler oder den nächsten Kundendienst.
DIE INSTALLATION EINES PUFFERKONDENSATORS MIT AUSREICHENDER KAPAZIÄT WIRD EMP-
FOHLEN. Hochleistungsverstärker verursachen sehr hohe Spannungsabfälle und benötigen eine sehr hohe
Stromstärke bei hoher Leistung. Um das Bordnetz des Fahrzeuges nicht übermäßig zu belasten, wird die
Installation eines Pufferkondensators (auch Pufferelko, Powercap oder Power Capacitor genannt) empfohlen,
der parallel zum Verstärker und zur Stromquelle als Puffer fungiert. Lassen Sie sich am besten im Car Audio
Fachhandel beraten.
VERKABELUNG UND EINBAU VON FACHPERSONAL AUSFÜHREN LASSEN. Die Verkabelung und der
Einbau dieses Gerätes erfordern technisches Geschick und Erfahrung. Zu Ihrer eigenen Sicherheit sollten Sie
Verkabelung und Einbau dem Händler überlassen, bei dem Sie das Gerät erworben haben.
VOR DER INSTALLATION DAS KABEL VOM MASSEPOL DER BATTERIE ABKLEMMEN. Bevor Sie mit
der Installation des Soundsystems beginnen, trennen Sie unbedingt den Massepol der Autobatterie ab, um
Kurzschlüsse und Stromschläge zu vermeiden.
WÄHLEN SIE EINEN GEEIGNETEN EINBAUORT. Suchen Sie einen geeigneten Einbauort für das Gerät, bei
dem ausreichend Raum für eine kühlende Luftzirkulation vorherrscht. Am besten geeignet sind Reserverad-
mulden und offene Bereiche im Kofferraum. Weniger geeignet sind Stauräume hinter der Seitenverkleidung
oder Bereiche unter den Fahrzeugsitzen.
DAS GERÄT NICHT AN STELLEN EINBAUEN, AN DENEN ES HOHER FEUCHTIGKEIT ODER STAUB
AUSGESETZT IST. Bauen Sie das Gerät so ein, dass es vor hoher Feuchtigkeit und Staub geschützt ist. Wenn
Feuchtigkeit oder Staub in das Gerät gelangen, kann es zu Betriebsstörungen kommen. Schäden am Gerät,
welche durch Feuchtigkeit hervorgerufen wurden, unter- liegen nicht der Garantie.
DAS GERÄT SOWIE ANDERE KOMPONENTEN DES SOUNDSYSTEMS AUSREICHEND BEFESTIGEN.
Andernfalls könnten sich die Geräte und Komponenten während der Fahrt lösen und als gefährliche Geschos-
se im Fahrgastraum Beschädigungen und Verletzungen hervorrufen.
SICHERHEITSHINWEISE

DEUTSCH
BEIM BOHREN VON LÖCHERN, BESTEHENDE KOMPONENTEN, LEITUNGEN UND KABEL DES FAHR-
ZEUGS NICHT BESCHÄDIGEN. Wenn Sie bei der Installation Löcher in das Fahrzeugchassis bohren, achten
Sie unbedingt darauf die Kraftstofeitungen, den Benzintank, elektrische Kabel und andere Leitungen nicht zu
beschädigen, zu berühren oder zu blockieren.
AUF KORREKTE ANSCHLÜSSE ACHTEN. Bei fehlerhaften Anschlüssen besteht Feuergefahr, Kurzschluss-
gefahr und es kann zu Schäden am Gerät kommen.
AUDIOKABEL UND STROMKABEL SOLLTEN NICHT ZUSAMMEN VERLEGT WERDEN. Bei der Installati-
on des Audiokabels zwischen dem Cinch-Ausgang des Autoradios und dem Cinch-Eingang des Verstärkers im
Fahrzeug ist darauf zu achten, dass das Audio- und das Stromversorgungskabel möglichst nicht auf der selben
Seite des Fahrzeugs verlegt werden. Besser ist eine räumlich getrennte Installation, im rechten und linken Ka-
belschacht des Fahrzeugs. Damit wird das Überlagern von Störungen auf das Audio-Signal verringert. Dieses
gilt ebenfalls für das Verbindungskabel der beiliegenden Kabel-Fernbedienung. Das Kabel sollte nicht auf der
Seite der Stromversorgungsleitung verlegt werden, sondern zusammen mit den Audiokabeln.
SORGEN SIE DAFÜR, DASS SICH DIE KABEL NICHT IN GEGENSTÄNDEN IN DER NÄHE VERFANGEN.
Verlegen Sie die Kabel wie auf den folgenden Seiten beschrieben, damit diese beim Fahren nicht hinderlich
sind. Kabel die sich im Bereich des Lenkrads, des Schalthebels oder im Bremspedal usw. verfangen können,
führen zu äußerst gefährlichen Situationen.
ELEKTRISCHE KABEL NICHT SPLEISSEN. Kabel dürfen nicht abisoliert werden, um andere Geräte mit
Strom zu versorgen. Andernfalls wird die Strombelastbarkeit des Kabels überschritten, und es besteht Feu-
ergefahr oder die Gefahr eines elektrischen Schlages. Verwenden Sie hierfür am besten geeignete Verteiler-
blöcke.
BOLZEN UND MUTTERN DER BREMSANLAGE NICHT ALS MASSEPUNKT VERWENDEN. Verwenden
Sie für den Einbau oder Masseanschluss keine Bolzen oder Muttern der Brems- bzw. Lenkanlage oder eines
anderen sicherheitsrelevanten Systems. Andernfalls besteht Feuergefahr oder die Fahrsicherheit ist beein-
trächtigt.
DIE KABEL SO VERLEGEN, DASS SIE NICHT GEKNICKT ODER DURCH SCHARFE KANTEN GE-
QUETSCHT WERDEN. Verlegen Sie die Kabel so, dass sie sich nicht in beweglichen Teilen wie den Sitzschie-
nen vefangen oder an scharfen Kanten oder spitzen Ecken beschädigt werden können. Wenn Sie ein Kabel
durch eine Bohrung in einer Metallplatte führen, schützen Sie die Kabelisolierung mit einer Gummitülle vor
Beschädigungen durch Metallkanten der Bohrung.
KLEINTEILE WIE SCHRAUBEN UND ANSCHLUSS-STECKER VON KINDERN FERNHALTEN. Werden
solche Gegenstände verschluckt, besteht die Gefahr schwerwiegender Verletzungen. Suchen Sie unverzüg-
lich einen Arzt auf, sollte ein Kind einen solchen Gegenstand verschluckt haben.

MECHANISCHE INSTALLATION
Bevor Sie mit der Installation des Soundsystems beginnen, trennen Sie unbedingt den
Massepol der Fahrzeugbatterie ab, um Kurzschlüsse und Stromschläge zu vermeiden.
ACHTUNG
• Achten Sie bei der Installation darauf, dass keine serienmäßig im KFZ vorhandenen Teile wie z.B. Kabel,
Bordcomputer, Sicherheitsgurte, Tank oder ähnliche Teile beschädigt bzw.entfernt werden.
• Vergewissern Sie sich, dass der Verstärker am Montageort genügend Kühlung erhält. Montieren Sie das
Gerät nicht in zu kleine, abgeschlossene Gehäuse ohne Luftzirkulation, in die Nähe von wärmeabstrahlende
Teilen oder elektronischen Steuerungen des Fahrzeuges.
• Montieren Sie den Verstärker auf keinen Fall auf ein Bassgehäuse oder andere vibrierende Teile, dadurch
können sich die Bauteile im Inneren losvibrieren und das Gerät ernsthaft beschädigen.
• Die Kabel der Stromversorgung und die Audiosignalkabel sollten bei dem Einbau so kurz als möglich gehal-
ten werden, um Verluste und Störungen zu vermeiden.
