NSTALLATION

• For safety, disconnect the negative lead from the car battery prior to beginning the installation
Trunk Mounting

Mounting the amplifier vertically on a surface with the fin grooves running up and down will provide the best cooling for the amplifier.

Passenger Compartment Mounting

Mounting the amplifier in the passenger compartment will work as long as you provide a sufficient amount of air for the amplifier to cool
itself. If you are going to mount the amplifier under the seat of the vehicle, you must have at least 1” (2.54cm) of air gap around the
amplifier’s heatsink.

B+ Terminal

The B+ cable MUST be fused 18” (45cm) or less from the vehicle’s battery. Prepare the cable ends and install the fuseholder under the
hood. Connections should be water tight.

GND Terminal

Prepare a length of cable to be used for the ground connection. Prepare the chassis ground by scraping any paint from the metal surface
and thoroughly clean the area of all dirt and grease. Fasten the cable to the chassis using a screw.

REM Terminal

Connect the REM wire to a switched 12 volt positive source. The switched signal is usually taken from the source unit’s auto antenna or
the accessory lead. If the source unit does not have these outputs available, the recommended solution is to wire a mechanical switch in­line with a 12 volt source to activate the amplifier.

Input Connectors

Follow the diagram and connect the appropriate signal cables to the input terminals of the amplifier. Be sure that the signal cables are
routed close together and away from any high current wires.

Speaker Output Terminals

Connect the speaker system to the amplifier by inserting the wires into the corresponding output terminals and tighten the set screws.
Follow the diagram for proper signal polarity. DO NOT chassis ground any of the speaker wires as unstable amplifier operation may

result. CAUTION: This amplifier is not recommended for impedance loads below 2Ω stereo and/or 4Ω bridged (mono).
Gain Control(s)

The amplifier is factory set for optimum dynamic range. The system levels may be adjusted by ear when using a source unit with higher or
lower output levels by using the following procedure.

1. Turn the gain control to minimum (counterclockwise)

2. Play a music track with high dynamic content and turn up the source unit to at least 3/4 volume

3. Slowly increase the gain and set it just below audible distortion or until reaching a comfortable hearing threshold (whichever occurs
first)

el compartimento del motor. Las conexiones han de ser impermeables.

Terminal GND

Prepare un trozo de cable para usarlo como toma de masa. Prepare un punto de masa en el chasis rascando y eliminando la pintura de
la superfcicie de metal y límpielo de toda suciedad asegure el cable al chasis con un tornillo.

Terminal REM (Encendido remoto)

Conecte el cable REM a un punto de +12V conmutable. La señal se suele coger de la salida auto antena del radio cassette si este no
tiene salida remote.

Conectores de Entrada

Siga el diagrama y conecte los cables adecuados para señal a los terminales de entrada del amplificador. Asegúre se que los cables de
señal esten canalizados en conjunto y lo más lejo posible de cualquier cable de alto amperaje.

Terminales de salida para los Parlantes

Conecte el sistema de parlantes al amplificador insertando los cables correspondientes en los ternminales de salida y luego aprete los
tornillos. Siga el diagrama para una adecuada polaridad de señal. NO CONECTE ninguno de los cables de los parlantes a la masa de

la carcasa, ya que esto puede resultar en una operación inestable del amplificador. PRECAUCION: este amplificador no está
recomendado para cargas de impedancia por abajo de 2 Ohmios en estéreo y/ó 4 Ohmios en modo puente (bridge mono).

Control(es) de Ganancia

El amplificador está dispuesto desde la fábrica para óptimo rango dinámico. Los niveles del sistema pueden ser ajustado por oído
cuando se utilice una unidad fuente con niveles de salidas más altos ó bajos, mediante el uso del siguiente procedimiento:

1. Lleve el control de ganancia al mínimo (en contra de las agujas del reloj)

2. Reproduzca una pista musical con alto contemiodo dinámico y lleve el volumen de la unidad fuente hasta unos 3/4 de máximo

3. Lentamente incremente la ganancia y pare justo bajo el nivel audible de distorsion ó hasta que llegue a un umbral agradable de
audición (cualquiera que ocurra primero)

NSTALLATION

• Pour votre sécurité, deéconnectez la borne négative de la batterie du véhicule avant de commencer le montage.

Montage dans l’habitacle

L’installation d’un amplificateur est envisageable dans l’habitacle dès que la convection naturelle est suffisante. Il est possible de fixer
l’amplificateur soud un siège si la hauteur de celui-ci permet au minimum d’avoir trois centimètres au-dessus du dissipateur thermique.

Alimentation
La connexion B doit être reliée impérativement via un fusible, directement à la borne positive de la batterie.
La connexion GND

Cette liaison référence l’amplificateur à la masse. La masse électrique du châssis n’a pas en tous points la même qualité. Il vous sera utile
de recourir aux compétences d’un professionel pour déterminer le meilleur point. Une fois trouvé, il faudra débarrasser la tôle de toutes
traces de peinture, le raccordement devra se faire par une vis acier (sans traitement de surface).

La connexion REM

Cette connexion est la commande à distance de mise en/hors service. Elle est généralement reliée à la sortie (antenne électrique de
l’autoradio) ou auprès d’une source de douze volts commutée.

Connecteur CINCH

Cette liaison assure la transmission de modulation entre l’autoradio et la source. En raison des faibles signaux véhiculés dans ces câbles,
ceux-ci devront être tenus à l’écart du faisceau électrique du véhicule et des câbles d’alimentation de l’amplificateur.

Connections haut-parleurs
Les haut-parleurs serons connectés sur cette partie du bornier. Soyez vigilant quant au sens du branchement + et –. Avertissement:
L’impédance globale en mode stéréo ne peut être inférieure à deux Ω et en mode ponté à quatre Ω.

Contrôle de sensibilité

A la sortie d’usine, l’amplificateur est réglé (valeur qui détermine la meilleure capacité dynamique). La sensibilité est variable pour
adapter l’amplificateur aux différentes sources qui ne possèdent pas le même niveau de sortie. Ce réglage est très important, il est

déterminant de la qualité de reproduction et de la pérennité de l’installation.
Méthodologie du réglage

1. Positionnez le réglage de sensibilité au minimum (à l’inverse du sens des aiguilles d’une montre)

2. Ecoutez un passage musical à grande dynamique (solo de guitare basse, etc.) avec le potentiomètre de volume de la source aul 3/4

3. Doucement dans le sens des aiguilles d’une montre tournez le potentiomètre de sensibilité de l’amplificateur jusqu’à percevoir une
déformation. A cette étape, il fault revenir juste en-dehors du seuil de déformation

4. Il faut répéter plusieurs fois cette procédure avec différents disques pour être sûr du réglage

INBAU

• Zur Sicherheit klemmen Sie den Negativ-Pol der Batterie während des gesamten Einbaues ab.

Im Fahrzeugkofferraum

Der vertikale Einbau der Endstufen, das bedeutet, dab die Kühlrippen von oben nach unten verlaufen, gibt dem Verstärker die beste Kühlung.

Auf der Beifahrerseite

Sollte der Verstärker auf der Beifahrerseite montiert werden, so ist es sehr wichtig für eine ausreichende Kühlung zu sorgen. Sollte der Verstärker z.B. unter
dem Beifahrersitz montiert werden, sollte dem Kühlkörper mindestens ein Luftspalt von 3 cm bleiben, um so für eine ausreichende Kühlung zu sorgen.

B+ Anschluβ

Die Plus-Leitung MUβ ca. 40 cm nach dem Plus-Pol der Batterie abgesichert sein. Preparieren Si die Kabellängen und montieren Sie den
Sicherungshalter im Motorraum. ALLE Verbindungen müssen wasserdicht sein.

GND Anschluβ

Preparieren Sie Ihr Kabel für Negativ Leitung (Erdung). Preparieren Sie die Anschlubstelle des Erdungskabels, indem Sie das Metall gründlich reinigen
und vom Lack befreien. Befestigen Sie nun die Erdung an dieser Stelle mit einer Schraube.

REM Anschluβ

Verbinden Sie das Ein-und Ausschaltungskontroll-Kabel mit Ihrem Radio (12 Volt positiv). Normalerweise verwenden Sie hierfür die Ant.-Remote). Sollte
Ihr Radio diesen Anschluβ nicht besitzen, so verwenden Sie eine 12 Volt Spannung, die Sie durch einen Schalter ein- und ausschalten können.

Eingangs-Anschlüβe

Beachten Sie den Anschlussplan und verbinden Sie die Signalkabel mit den Eingangs-Anschluessen des Verstärkers. Seien Sie sicher, dass die Kabel dicht
zusammen und entfernt von stromfuehrenden Kabeln liegen.

Lautsprecher Ausgänge

Verbinden Sie das Lautsprechersystem mit dem Verstärker, indem Sie die Kabel in die entsprechenden Anschluesse stecken und verschrauben. Beachten
Sie hierbei den Anschlussplan, um eine korrekte Polarität zu gewährleisten. Erden Sie niemals eine der Lautsprecherleitung auf die Masse des

Fahrzeuges. Achtung: Die minimale Last von 2

Ω Stereo und/oder 4Ω gebrueckt (Mono) darf nicht unterschritten werden.

Eingangsempfindlichkeit

Der Verstärker ist Werkssetig auf eine Eingangsspannung. Die Eingangsempfindlichkeit kann nach Gehoer verstellt werden, wenn die Ausgangsspannung
des Steuergerätes hoeher oder niedriger ist. Gehen Sie wie folgt vor.

1. Drehen Sie die Eingangsempfindlichkeit auf ein Minimum (gegen den Uhrzeigersinn).

2. Speilen Sie einen Musiktitel mit einer sehr hohen Dynamik und drehen Sie die Lautstärkekontrolle des Steuergerätes auf ä der Maximallautstärke.

3. Jetzt verstellen Sie die Eingangsempfindlichkeit des Verstärkers soweit (im Uhrzeigersinn drehen), bis Sie eine Verzerrung des Signals wahrnehmen.
Danach sollte ie Empfindlichkeit wieder soweit zurueck gedreht werden (gegen den Uhrzeigersinn), bis die Verzerrungen verschwindern.

Montare l’amplificatore nell’abitacolo si avrá un funzionamento regolare se si garantisce un flusso d’aria sufficiente. Per l’installazione
sotto un sedile, é necessario avere uno spazio di almeno 3 cm attorno a tutto l’amplificatore.

Terminale B+ (cavo positivo)

Il cavo positivo deve essere protetto da un fusibile a non piú di 45 cam dalla batteria. Terminare il cavo e installare il fusibile nel vano
motore. Tutte le connessioni devono essere a prova d’acqua.

Terminal GND (cavo negativo)

Decidere la lunghezza del cavo e terminarlo. Preparare la massa grattando la vernice dal telaio dell’auto ed eliminando tracce di olio o
sporco. Fissare il cavo di massa al telaio con una vite.

Terminal REM (Consenso di accensione)

Collegare il cavo REM ad un positivo present solo ad autoradio accessa (normalmente il cavo pilota dell’antenna elettrica o il cavo
accessori dell’autoradio). Se la sorgente non dovesse essere equipaggiata con queste uscite, la soluzione raccomandabile é di inserire un
interruttore su un cavo positivo e connettersi all’amplificatore.

Connettori di ingresso

Seguendo lo schema collegate i cavi di segnale agli appropriati terminali di ingresso dell’amplificatore. Assicuratevi che i cavi di segnale
siano passati vicini tra loro e lontano da cavi ad alta corrente.

Connettori degli altoparlanti

Collegate il sistema di altoparlanti inserendo i cavi nei terminali corrispondenti e serrate le viti. Seguite lo schema per l’ottimale colle
gamento delle polaritá. Non cortocircuitate a massa nessun cavo degli altoparlanti, potrebbe verificarsi un anomalo comportamento

dell’amplificatore. ATTENZIONE; questo amplificatore non é raccomandato per impedenze inferiori ai 2 ohm stereo w/o 4 ohm
mono a ponte.

Controlli della sensibilitá

L’amplificatore é regolato dalla casa per un ottimale rendimento dinamico. Il lilvello di ingresso puó essere regolato anche ad orecchio
quando si impiega una sorgente con uscita superiore od inferiore. Seguite questa procedure:

1. Portate il controllo della sensibilitá al minimo (senso antiorario)

2. Suonate un brano musicale con elevato contenuto dinamico portando il volume della sorgente a circa 3/4

3. Aumentate lentamente il livello di ingresso dell’amplificatore e posizionatelo subito prima dell’insorgere di distorsione o quando il
livello generale vi appaia confortevole

ISOLUZIONE DEI PROBLEMI

Sintomo Diagnosi Rimendo

L’ampificatore non si accende

Il B+ o il REM n on hanno una tensione
compresa tra i 10,5 e 15,5 volt o nessuna
tensione é presente

L’amplificatore non é correttamente a massa

Verficate l’alternatore, la batteria, i fusibilit,
il cablaggio e riparate quanto necessario

Controllate il cablaggio e riparat se
necessario

Rumore dell’amplificatore

(bump di accensione)

Rumore dal motore

Picchi di tensione provenienti dalla sorgente
entrano dall’ingresso dell’amplificatore

Il rumore si propagna nei cavi di segnale

– 12 –

Se il bump si elimina disconnettendo gli
ingressi, collegate un modulo di accensione

Ristendete i cavi di segnale lontano da cavi
ad alta corrente
