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

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.

Using a speaker that supports bi-amp connection

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

use 8-ohm speakers and set IMPEDANCE SELECTOR to the upper position (p.7).

Using three speakers for one channel (multi-speaker)

If you want to use three speakers for reproducing CH.1 audio signals (such as center

channel signals), change the CH. SELECTOR setting and connect the speakers to the

CH.1 and CH.4 (L/R) terminals.

If the problem you are experiencing is not listed below or if the instructions below do not help, turn off the unit, disconnect the power cable, and contact the nearest authorized

Yamaha dealer or service center.

First, check the followings:

a The power cables of the unit and other devices (such as a pre-amplifier) are connected to AC wall outlets securely.

b The unit and other devices (such as a pre-amplifier) are turned on.

c The connectors of each cable are securely inserted in to jacks on each device.

Problem Cause Remedy

The power does not turn on.

The protection circuitry has been activated three times

consecutively. When the unit is in this condition, the power

indicator on the unit blinks.

As a safety precaution, capability to turn on the power is disabled. Contact your

nearest Yamaha dealer or service center to request repair.

The internal microcomputer has frozen, due to an external electric

shock (such as lightning or excessive static electricity) or to a drop

in the power supply voltage.

Disconnect the power cable from the AC wall outlet and plug it again.

An external device is connected to the TRIGGER (IN) jack. Press down z (power) on the unit and then turn on the external device.

The power turns off (standby mode) immediately.

The unit was turned on while a speaker cable was shorted.

Twist the bare wires of each speaker cable firmly and reconnect to the unit and

speakers (p.7).

The unit was shorted because the speaker terminals come into

contact with metal parts of the AV rack, etc.

Keep enough space on the back of the unit (p.i).

The unit enters standby mode automatically.

The auto-standby function worked.

To disable the auto-standby function, set the AUTO POWER STANDBY switch to

“OFF” (p.8).

The protection circuitry has been activated because the volume of

the external device connected to the unit is too high.

Turn down the volume of the external device.

The protection circuitry has been activated because the

temperature inside of the unit is too high.

Install the unit in a well ventilated, place and allow enough ventilation space

around the unit (p.i).

No sound. The BAL/UNBAL switch setting is not correct. Change the BAL/UNBAL switch setting so that it matches the connections (p.6).

No sound is coming from a specific speaker.

The speakers connected to the CH.2 A/B terminals are turned off. Press SPEAKERS A/B to turn on the speakers (p.10).

The XLR balanced cable (or RCA unbalanced cable) connecting

the unit and pre-amplifier is defective, or the speaker cable

connecting the unit and speaker is defective.

If there is no problem with the connection, replace with another cable.

Another channel sound is coming from a specific

speaker.

The CH SELECTOR setting is not correct. Change the CH SELECTOR setting so that it matches your speaker system (p.10).

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

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)

2 Fr Fonctions

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.
