•Protection circuit.
•Pulse power supply
* for stable, regulated output
power.
* Pulse power supply
This unit has a built-in power regulator which
converts the power supplied by the DC 12 V car
battery into high speed pulses using a
semiconductor switch. These pulses are stepped
up by the built-in pulse transformer and
separated into both positive and negative power
supplies before being converted into direct
current again. This light weight power supply
system provides a highly efficient power supply
with a low impedance output.
Caractéristiques
•Puissance de sortie maximale de 280 W par canal
(à 4
Ω ).
•Cet appareil peut être utilisé comme
amplificateur en pont avec une sortie maximale
de 800 W.
•Une connexion directe est possible avec la sortie
haut-parleur de votre autoradio si celle-ci n’est
pas équipée d’une sortie de ligne (connexion
d’entrée haut niveau).
•Une fonction de mise sous tension par détection
de haut niveau permet à cet appareil d’être activé
sans raccordement à REMOTE.
•Filtre passe-bas (LP), filtre passe-haut (HP) et

intégrés.
•Double mode de connexion possible au moyen
d’un système à plusieurs haut-parleurs.
•Circuit de protection.
•Alimentation électrique par impulsions
* pour
une puissance de sortie stable, régulée.
Alimentation électrique par impulsions
Cet appareil est équipé d’un régulateur de
puissance intégré qui convertit la puissance
fournie par une batterie de voiture de 12 V CC en
impulsions ultra-rapides au moyen d’un
commutateur à semi-conducteur. Ces impulsions
sont amplifiées par le transformateur
d’impulsions intégré et séparées en alimentation
positive et négative avant d’être reconverties en
courant continu. Ce système d’alimentation de
faible poids assure une alimentation électrique
très efficace pour une sortie d’impédance faible.

Caution
• Before making any connections, disconnect
the ground terminal of the car battery to avoid
short circuits.
• Be sure to use speakers with an adequate
power rating. If you use small capacity
speakers, they may be damaged.
• Do not connect the # terminal of the speaker
system to the car chassis, and do not connect
the
# terminal of the right speaker with that
of the left speaker.
• This is a phase-Inverted Amplifier.
• Install the input and output cords away from
the power supply wire as running them close
together can generate some interference noise.
• This unit is a high powered amplifier.
Therefore, it may not perform to its full
potential if used with the speaker cords
supplied with the car.
• If your car is equipped with a computer
system for navigation or some other purpose,
do not remove the ground wire from the car
battery. If you disconnect the wire, the
computer memory may be erased. To avoid

Notes
•When using passive crossover networks in a multi-
speaker system, care must be taken as the speaker
system’s impedance should not be lower than that
of the suitable impedance for this unit.
•When you are installing a 12 decibels/octave system
in your car, the following points must be
considered. In a 12 decibels/octave system where
both a choke and capacitor are used in series to
form a circuit, a great care must be taken when
they are connected. In such a circuit, there is going
to be an increase in the current which by-passes the
speaker with frequencies at around the crossover
frequency. If audio signals are continued to be fed
into the crossover frequency area, it may cause the
amplifier to become abnormally hot or the fuse will
be blown. Also if the speaker is disconnected, a
series-resonant circuit will be formed by the choke
and the capacitor. In this case, the impedance in the
resonance area will decrease dramatically resulting
in a short circuit like situation causing a damage to
the amplifier. Therefore, make sure that a speaker
is connected to such a circuit at all times.
Remarques
•Lorsque vous utilisez des circuits de recoupement de
fréquence passifs dans un système à plusieurs haut-parleurs,
assurez-vous que l’impédance du système n’est pas inférieure
à celle prévue pour cet appareil.
•Lorsque vous installez un système à 12 décibels/octaves dans
votre voiture, vous devez respecter les points suivants. Dans
un système à 12 décibels/octaves où la bobine d’arrêt et le
condensateur sont utilisés en série pour former un circuit,
vous devez réaliser les branchements avec beaucoup de
précaution. Dans ce type de circuit, une augmentation du
courant contournant le haut-parleur se produit dans les
fréquences se situant autour de la fréquence de coupure. Si
des signaux audio continuent d’être fournis dans la zone de
la fréquence de recoupement, une surchauffe risque de se
produire dans l’amplificateur et le fusible risque de griller. Si
le haut-parleur n’est pas raccordé, un circuit de résonance
série sera créé par la bobine et le condensateur. Dans ce cas,
l’impédance dans la zone de résonance sera
considérablement réduite, et comme dans le cas d’un court-
circuit, l’amplificateur peut être endommagé. Par
conséquent, veillez à ce qu’un haut-parleur soit toujours
raccordé au circuit.

Bias Adjustment
Note : In Bias Adjustment, adjust RV103 if any of Q108 through
Q111 are replaced. Adjust RV203 if any of Q208 through
Q211 are replaced.
Condition :This adjustmentshould beperformed aboutone minute
after the remote mode is turned on at a room tempera-
ture of about 25°C.
Setting :
SECTION 3
ELECTRICAL ADJUSTMENT
Procedure :
1. Turn the variable resistors RV103 (L-CH) and RV203 (R-CH)
full clockwise as seen from the component side to minimize the
bias current.
2. The input signal is to be no signal.
3. Apply the voltage to the +12V and REM terminals from the sta-
bilized power supply and gradually increase it up to 14.4V while
checking for any unusual current.
4. Adjust each of RV103 (L-CH) and RV203 (R-CH) so that the
power current of the stabilized power supply is increased in steps
of 550 mA.
