Precaution for use
Read the supplied booklet “Safety Brochure” before using the unit.
Install the unit in a well ventilated, cool, dry, clean place – away from direct sunlight,
heat sources, vibration, dust, moisture, and/or cold. Allow ventilation space of at
least 30 cm (11-3/4”) on the top, 20 cm (7-7/8”) on the left and right, and 20 cm
(7-7/8”) on the back of the unit.
30 cm (11-3/4”) or more
20 cm (7-7/8”) or more
20 cm (7-7/8”) or more
Since the unit adopts bare metallic speaker terminals, make sure keeping enough
space on the back of the unit. If the speaker terminals come into contact with metal
parts of the AV rack, etc., the unit will be shortened and damaged.
Also, never touch the speaker terminals when the unit is powered on since it may
cause an electrical shock.
The unit does not have volume controls. Make sure you connect a device with
volume control (such as a pre-amplifier) to the unit. If you connect a device without
volume control (such as a CD player) directly to the unit, the volume may become
excessively loud and result in damage to the unit or speakers.
Be careful with short circuits.
DO NOT TOUCH!

2 En Features
Features
High-quality power amplifier
High output/high audio-quality
amplifier (150 W x 11 channels)
The unit provides an 11-channel power amplifier
featuring a three-stage Darlington current feedback
circuit, with a power supply that uses the same type of
toroidal transformer used in top-level hi-fi audio devices.
The gold-plated speaker connectors are also of the
highest quality, delivering high-grade sound.
Balance and unbalanced
connections are supported
Balanced (XLR) and unbalanced (RCA) input jacks are
provided on all channels, and can be selected
independently for each channel.
Balanced connections minimize the extraneous noise
that can arise in the cable connection between the unit
and the pre-amplifier, ensuring high-fidelity transmission
of the audio signal.
Unbalanced connections utilize ground-sensing to
achieve fidelity that is close to balanced transmission.
Chassis structure that maximizes
the potential of the unit's
performance
The chassis features a special structure that allows the
full potential of the high-quality power amplifier’s
potential to be revealed.
Symmetrical power amplifier design
Aluminum front panel and side panels
Extremely stable feet utilizing the A.R.T.
(Anti-Resonance Technology)
Expandable to meet diverse needs
Freedom for speaker placement
Since power amplifiers of the identical specification are
provided for all 11 channels, you use the unit not only
for constructing a home theater setup of up to
11 channels but also for multi-room systems or any
other speaker configuration to meet your needs.
Support for bi-amp connections
and multi-speaker playback
The unit provides a channel selector function that lets
you utilize bi-amp connections or multi-speaker
connections without having to connect additional
cables from your pre-amplifier. For example, the CH.2
audio input could be output from both the CH.2 and
CH.3 speaker outputs to drive a bi-amp configuration
for high-quality sound, or the CH.1 (monaural) input
could be output from three speakers connected to CH.1
and CH.4 (L/R).
Switch the unit's power from your
pre-amplifier (trigger function)
The unit can switch its own power status in
synchronization with power switching operations on
another device that supports the trigger function, such
as an AV pre-amplifier (TRIGGER IN). The input signal
from the TRIGGER IN jack can also be output without
change in a cascade connection to switch the power of
another device such as a Yamaha subwoofer
(THROUGH OUT). In addition, another device can be
switched in synchronization when the power of the unit
is switched (TRIGGER OUT), allowing you to set up a
variety of systems with synchronized power switching.

If you want to use a speaker that supports bi-amp connection to have more high-quality
sounds, change the CH. SELECTOR setting and connect the speaker to the
corresponding pair of the SPEAKERS terminals.
(Example)
Using a speaker that supports bi-amp connection for CH.2 (R)
By setting the CH. SELECTOR for CH.3 (R) to “CH.2”, CH.2 (R) input signals are output
from both the CH.2 (R) and CH.3 (R) speaker terminals. In this case, CH.3 (R) input is
not used.
Using two pairs of front speakers (SPEAKERS A/B)
If you connect two pairs of front speakers to the CH.2 A/B terminals, you can switch the
front speakers to be used by pressing SPEAKERS A/B on the front panel of the unit.
When using two pairs of the speakers connected to the CH.2 A/B terminals at the same time, be sure to

Précautions à prendre
Lisez le livret fourni « Brochure sur la sécurité » avant d’utiliser l’unité.
Installez l’unité dans un endroit propre, sec, frais et bien ventilé, où il ne risque pas
d’être exposé directement à la lumière du soleil, à la poussière, à l’humidité, au froid
et/ou soumis à des vibrations. Veillez à disposer de suffisamment d’espace pour
assurer une ventilation adéquate : au moins 30 cm au-dessus de l’unité, 20 cm sur
les côtés et 20 cm à l’arrière.
30 cm minimum
20 cm minimum
20 cm minimum
Étant donné que l’unité est dotée de bornes d’enceinte à surfaces métalliques nues,
veillez à laisser un espace suffisant à l’arrière de l’unité. Si les bornes d’enceinte
entrent en contact avec les parties métalliques du bâti AV, un court-circuit se produit
au niveau de l’unité, risquant d’endommager cette dernière.
Par ailleurs, ne touchez jamais les bornes d’enceinte lorsque l’unité est sous tension,
car cela pourrait provoquer un choc électrique.
L’unité n’est pas dotée de commandes de volume. Assurez-vous de raccorder à
l’unité un appareil doté d’une commande de volume (par exemple, un préamplificateur).
Si vous raccordez un appareil sans commande de volume (par exemple, un lecteur
CD) directement à l’unité, le volume risque d’être assourdissant et des dommages
peuvent survenir au niveau de l’unité ou des enceintes.
Faites attention aux
courts-circuits.
NE PAS TOUCHER !
(lorsque l’unité est sous tension)

Fonctions
Amplificateur de puissance haute
qualité
Amplificateur haute
puissance/haute qualité audio
(150 W x 11 voies)
L’unité est dotée d’un amplificateur de puissance 11 voies
muni d’une boucle de retour de courant Darlington à
trois niveaux, alimenté par un transformateur toroïdal
similaire à ceux utilisés dans les appareils audio Hi-Fi
haut de gamme. Les connecteurs d’enceinte plaqués or
sont également d’excellente qualité et produisent un
son d’une précision remarquable.
Prise en charge des connexions
symétriques et asymétriques
Des prises d’entrée symétriques (XLR) et asymétriques
(RCA) sont fournies sur toutes les voies et peuvent être
sélectionnées de manière indépendante pour chaque
voie.
Les connexions symétriques réduisent les bruits parasites
susceptibles d’être captés au niveau du raccordement
du câble entre l’unité et le préamplificateur, garantissant
ainsi une transmission haute fidélité du signal audio.
Les connexions asymétriques utilisent un détecteur au
sol pour obtenir une fidélité proche de la transmission
symétrique.
Structure de châssis exploitant
tout le potentiel de performances
de l’unité
Le châssis présente une structure spéciale permettant de
libérer tout le potentiel de l’amplificateur de puissance
haute qualité.
Conception d’amplificateur de puissance symétrique
Panneaux avant et latéraux en aluminium
• Pieds extrêmement stables utilisant la technologie A.R.T.
(Anti-Resonance Technology, technologie antirésonance)
Évolutivité pour répondre à divers besoins
Liberté de positionnement des
enceintes
Étant donné que les 11 voies sont dotées d’amplificateurs
de puissance partageant les mêmes caractéristiques
techniques, l’unité permet non seulement de configurer
un Home Cinéma 11 voies maximum mais aussi des
systèmes multipièces ou d’autres combinaisons
d’enceintes selon vos besoins.
Prise en charge de connexions
bi-amplificatrices et de la lecture
multi-enceintes
Grâce à la fonction de sélecteur de voies dont est dotée
l’unité, vous pouvez utiliser des connexions
bi-amplificatrices ou multi-enceintes sans avoir à
raccorder des câbles supplémentaires au niveau de
votre préamplificateur. Par exemple, l’entrée audio CH.2
peut être émise par les sorties des enceintes CH.2 et
CH.3 pour former une configuration bi-amplificatrice et
transmettre un son haute qualité, ou bien l’entrée CH.1
(mono) peut être émise par trois enceintes raccordées à
CH.1 et CH.4 (L/R).
Mise sous/hors tension de l’unité
depuis votre préamplificateur
(fonction de déclencheur)
La mise sous/hors tension de l’unité peut se faire de
manière synchronisée avec le dispositif de mise
sous/hors tension d’un autre appareil prenant en charge
la fonction de déclencheur, par exemple, un préampli
audio-vidéo (TRIGGER IN). Le signal d’entrée de la
prise TRIGGER IN peut également être restitué sans
dégradation dans un raccordement en cascade pour
mettre sous/hors tension un autre appareil, par exemple
un subwoofer Yamaha (THROUGH OUT). De plus, la
mise sous/hors tension d’un appareil externe peut se
faire de manière synchronisée avec la mise sous/hors
tension de l’unité (TRIGGER OUT), ce qui vous permet
de configurer plusieurs systèmes avec commutation
d’alimentation synchronisée.
