INSTALLATION
• 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 in-
line 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 Ω 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)

TROUBLESHOOTING
Symptom Diagnosis Remedy
Amplifier does not turn on. B+ or REM not between 10.5 and 15.5 volts or Check the alternator, battery, fuse, and
no voltage present wiring and repair as necessary

INSTALLATION
• 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

SOLUTIONS AUX PROBLÈMES

Symptôme Diagnostic Solution

INSTALLAZIONE
• Per sicurezza, scollegare il polo netativo della batteria dell’auto prima di iniziare l’installazione.
Nel Bagagliaio
Montando l’amplificatore su una superficie in verticale con le alette direzionate dall’alto verso il basso si garantirá un miglior
raffreddamento dell’amplificatore.
Nel’abitacolo
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

RISOLUZIONE DEI PROBLEMI
