SECTION 1
GENERAL This section is extracted
from instruction manual.
Features
•Maximum power output of 400W per channel
(at 4 Ω).
•This unit canbe usedasa bridging amplifier
with a maximum output of 1,200 W.
•Direct connection can be made with the speaker
output of your car audio unit if it is not equipped
with a line output (High level input connection).
•Built-in variable LPF (Low-pass filter) and low
boostcircuit.
•Dual mode connection possible for a multi-
speakersystem.
•Protection circuit.
•Pulsepower supply*for stable,regulated output
power.
* Pulsepower 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. Thesepulses 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
•Puissancede sortie maximale de 400W par canal
(à4 Ω).
•Cetappareil peut êtreutilisé comme
amplificateur en pont d’une sortie maximale de
1200W.
•Une connexion directe est possible avec la sortie
haut-parleur de votre autoradio si celle-ci n’est
paséquipée d’une sortie de ligne (connexion
d’entrée haut niveau).
•Filtre passe-bas(LPF) intégré et circuit
d’amplification de bassesfréquences.
•Double mode de connexion possible au moyen
d’un systèmeàplusieurs haut-parleurs.
•Circuit de protection.
•Alimentation électrique par impulsions *pour
une puissancede 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 CCen
impulsions ultra-rapides au moyen d’un
commutateur à semi-conducteur. Cesimpulsions
sont amplifiées par le transformateur
d’impulsions intégré et séparéesen 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
•Beforemaking any connections,disconnect
the ground terminal of the car battery to avoid
short circuits.
•Besure to use speakerswith an adequate
power rating. If you usesmall capacity
speakers,they may bedamaged.
•Do not connect the#terminal of the speaker
system to the car chassis, and do not connect
the #terminal of the right speakerwith that
of the left speaker.
•Install the input and output cords away from
the power supply wire asrunning them close
together cangeneratesomeinterference noise.
•This unit is a high powered amplifier.
Therefore, it may not perform to its full
potential if used with the speakercords
supplied with the car.
•If your car is equipped with acomputer
systemfor navigation or someother purpose,
do not remove the ground wire from the car
battery. If you disconnect the wire, the
computer memory may beerased.To avoid
short circuits when making connections,
disconnect the +12V power supply wire until
all the other wires have beenconnected.

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-passesthe
speaker with frequencies at around the crossover
frequency. If audio signals are continued to be fed
into the crossover frequency area, it may causethe
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/octave dans
votre voiture, vous devez respecter les points suivants. Dans
un système à 12 décibels/octave 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 sesituant 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 cecas,
l’impédance dans la zone de résonance sera
considérablement réduite, et comme dans le casd’un court-
circuit, l’amplificateur peut être endommagé. Par
conséquent, veillez à ce qu’un haut-parleur soit toujours
raccordé au circuit.

pouvez raccorder jusqu’à trois amplificateurs.
Sinon les niveaux de sortie requis ne peuvent
pas être obtenus et votre auto-radio risque

When you connect amplifiers using the

connect up to a maximum of three.
Otherwise the necessaryoutput levels can not

Use the THROUGHOUT terminal when you
install more amplifiers. Audio signals pass

Bias Adjustment
Note :In Bias Adjustment, adjust RV103 if any of Q108 through
Q113 are replaced. Adjust RV203 if any of Q208 through
Q213 are replaced.
Condition :This adjustmentshould be performed about oneminute
after the remote mode is turned on at a room tempera-
ture of about 25°C.
Setting :
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 B+ and REM terminals from the stabi-
lized power supply and gradually increase it up to 12.0 V 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 700 mA (total of 1.4 A).
5. After adjustment, check that the power current is at 1.65 to 2.05A.
Adjustment Location : Main board (component side)
