Owner’s Manual

Caution

■ Read the following before using the speaker:

• To assure the finest performance, please read
this manual carefully. Keep it in a safe place for
future reference.

• Install the speakers in a cool, dry, clean place
away from windows, heat sources, sources of
excessive vibration, dust, moisture and cold.
Avoid sources of humming (transformers,
motors). To prevent fire or electric shock, do
not expose the speakers to dripping or
splashing.

• To prevent the enclosure from warping or
discoloring, do not place the speakers where
they will be exposed to direct sunlight or
excessive humidity.

• Do not place the following objects on top of the
speakers:

1. Glass, china, etc.

If glass etc. falls by vibrations and breaks, it
may cause personal injury.

2. A burning candle etc.

If the candle falls by vibrations, it may
cause fire and personal injury.

3. A vessel with water in it

If the vessel falls by vibrations and water
spills, it may cause damage to the unit, and/
or you may get an electric shock.

• Do not place the speakers where foreign
objects such as water drips might fall. It might
cause a fire, damage to this unit, and/or
personal injury.

• Do not place the speakers where they are liable
to be knocked over or struck by falling objects.
Stable placement will also ensure better sound
performance.

• Secure placement or installation is the owner’s
responsibility. Yamaha shall not be liable for
any accident caused by improper placement or
installation of speakers.

• Any time you note distortion, reduce the
volume of your amplifier immediately. Make
sure the input power does not exceed the
specified maximum input power, otherwise the
speakers will be damaged.

• Do not attempt to clean the speakers with
chemical solvents as this might damage the
finish. Use a clean, dry cloth.

• Do not attempt to modify or fix the speakers.
Contact qualified Yamaha service personnel
when any service is needed. The cabinet
should never be opened for any reasons.

Note:

This speaker is magnetically shielded, but placing
them too close to a TV may impair the TV picture. If
this happens, move the speaker away from the TV.

Precautions When

Supplied Accessories

Positioning the Speakers

The speaker is constructed with the majority of
the weight located in its upper portion, and is thus
susceptible to falling over if proper care is not
taken to insure its stability. If the speaker falls
over, it may damage the speaker or be the cause of
injury (or even death) to persons and/or damage to
personal property.

■ For safe and proper use of the speaker:

• Position the speaker in a location that is solid,
level, smooth, and low (with respect to the
floor).

• Do not push or apply pressure to the side of the
speaker when moving, or lean objects against
the side of the speaker.

• Do not sit on or set objects on top of the
speaker.

Vibrations or jolts associated with earthquakes
and other phenomena or activities may cause the
speaker to fall over. For safety reasons, using
commercially available products that increase
stability in the speaker is recommended (metal
fittings or chains, etc.).

■ Use the stands included with the

speaker to increase stability:

Be sure to use the stands regardless of where the
speaker is positioned. Attaching the stands
included with the speaker reinforces the base of
the speaker not to fall over.

Please be cautioned that even though the stands
are connected, this does not guarantee that the
speaker will not fall over.

Placing the Speakers

Attaching the Stands

English

Place the speakers on a sturdy, vibration-free
surface.

■ Using as Normal Stereo Speakers

To get the best stereo performance, angle the
speakers inward so as to create a triangle, with the
listener at the apex.

■ Using as Front Speakers in a Surround Sound System

Position the speakers both side of your TV. The
positioning of these speakers is important because
they provide a solid anchor for the sound image.
They should be positioned facing the listener at
about ear level, and equidistant from the TV.

NS-50F

When placing the speakers, be sure to use the
stands to increase stability.

Use the 8 specified holes located on the base of
the speaker.

■ Procedure:

1. Put the screw through the inner hole of the
stand, and screw it into the outside hole of
the speaker. Do not tighten too much at this
point.

2. Put a screw through the outer hole on the

stand, and screw it into the other hole on
the base of the speaker.

3. Tighten both of the screws firmly.

4. Attach a pad to the bottom of the end

portion of the stand.

5. Attach the other stands to the other corners

of the base of the speaker in the same way
and confirm that all 4 stands have been
firmly attached.

Note:

Be careful not to apply force to the side of the speaker,
otherwise the speaker may fall causing damage to the
speaker or personal injury.

Connecting Your Speakers

Always turn off your amplifier or receiver
before making any connections.

■ Preparing Your Speaker Cables

Carefully remove 10 mm (3/8 ”) of insulation
from both ends of your speaker cables and twist
the bare wires tightly, as shown.

Notes:

• Make sure that the bare wires are not touching each
other as this could damage the speaker and
amplifier.

• Connect one speaker to the left terminals of your
amplifier, and another speaker to the right
terminals, making sure not to reverse the polarity
(+, –). If one speaker is connected with reversed
polarity, the sound will be unnatural and lack bass.

SYSTEME D’ENCEINTES

Nous vous remercions d’avoir opté pour le système d’enceintes de Yamaha.

Prècautions

■ Lisez ces précautions attentivement avant d’utiliser votre enceinte:

• Pour garantir les meilleures performances
possibles, lire ce manuel avec attention. Le
garder dans un endroit sûr pour une utilisation
ultérieure.

• Installer cette enceinte dans un endroit frais,
sec et propre, loin de fenêtres, sources de
chaleur et d’endroits où les vibrations, la
poussière, l’humidité ou le froid sont
importants. Eviter les sources de
bourdonnements (transformateurs, moteurs).
Pour éviter les risques d’incendie ou
d’électrocution, tenez les enceintes à l’écart de
tout liquide et de toute source d’éclaboussures.

• Pour éviter que le coffret se gondole ou se
décolore, ne pas placer l’enceinte à un endroit
ou elle sera exposée aux rayons directs du
soleil ou à une trop forte humidité.

• Ne posez jamais les objets suivants au-dessus
des enceintes:

1. Verres, porcelaine, etc.

Si les verres, etc., tombent sous l’effet des
vibrations et se rompent, ceci risque de
causer des blessures.

2. Une bougie allumée, etc.

Si la bougie tombe sous l’effet des
vibrations, ceci risque de causer un
incendie et des blessures.

3. Un récipient contenant de l’eau

Si le récipient tombe sous l’effet des
vibrations et que l’eau se répand, ceci
risque d’endommager l’appareil et/ou de
causer une électrocution.

• Ne pas placer l’appareil dans un endroit où des
corps étrangers comme des gouttes d’eau
peuvent tomber à l’intérieur. Ceci peut causer
un incendie, des dommages à l’appareil et/ou
une blessure corporelle.

• Ne pas placer l’enceinte à un endroit où elle
risque d’être renversée ou percutée par des
objets tombants. Un endroit bien stable
améliorera aussi la qualité du son.

• Le propriétaire du système est entièrement
responsable du bon positionnement et de la
bonne installation du système. YAMAHA
décline toute responsabilité en cas d’accident
causé par un positionnement ou une
installation inadéquats de l’enceinte.

• Si vous remarquez que le son sature, diminuez
immédiatement le volume sur l’amplificateur.
Vérifiez que la puissance d’entrée ne dépasse
pas la puissance d’entrée maximum spécifiée,
faute de quoi les enceintes seront
endommagées.

• Ne pas essayer de nettoyer cette enceinte avec
des diluants chimiques, ceci endommagerait le
fini. Utiliser un chiffon propre et sec.

• Ne pas essayer de modifier ni de réparer
l’enceinte. Contacter un dépanneur YAMAHA
qualifié en cas de nécessité de réparation. Le
coffret ne doit jamais être ouvert pour quelque
raison que ce soit.

Remarque:

Bien que ce système d’enceintes comporte un blindage
magnétique, il pourrait provoquer une distorsion de
l’image si vous le placez trop près d’un téléviseur.
Dans ce cas, éloignez les enceintes du téléviseur.
