Read this 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 speaker 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
electrical shock, do not expose the speaker to rain or
water.
• To prevent the enclosure from warping or discoloring,
do not place the speaker where it will be exposed to
direct sunlight or excessive humidity.
• Do not place the following objects on the speaker:
Glass, china, etc.
If glass etc. falls by vibrations and breaks, it may
cause personal injury.
A burning candle etc.
If the candle falls by vibrations, it may cause fire and
personal injury.
A vessel with water in it
If the vessel falls by vibrations and water spills, it may
cause damage to the speaker, and/or you may get an
electric shock.
• Do not place the speaker where foreign objects such as
water drips might fall. It might cause a fire, damage to
the speaker, and/or personal injury.
• Do not place the speaker where it is liable to be
knocked over or struck by falling objects. Stable
placement will also ensure better sound performance.
PRECAUTIONS
• Placing the speaker on the same shelf or rack as the
turntable can result in feedback.
• Never put a hand or a foreign object into the port
located on the rear of the speaker as this might cause
personal injury and/or damage to the speaker.
• When moving the speaker, do not hold the port as it
might cause personal injury and/or damage to the
speaker.
• Any time you note distortion, reduce the volume control
on your amplifier to a lower setting. Never allow your
amplifier to be driven into “clipping”. Otherwise the
speaker may be damaged.
• When using an amplifier with a rated output power
higher than the nominal input power of the speaker,
care should be taken never to exceed the speaker’s
maximum input.
• Do not attempt to clean the speaker with chemical
solvents as this might damage the finish. Use a clean,
dry cloth.
• Do not attempt to modify or fix the speaker. Contact
qualified Yamaha service personnel when any service is
needed. The cabinet should never be opened for any
reasons.
• Secure placement or installation is the owner’s
responsibility.
Yamaha shall not be liable for any accident caused
by improper placement or installation of the speak-
er.
PLACING THE SPEAKER
Front
Surround
Subwoofer
NS-C901
The grille is detached from the speaker and packed sepa-
rately. Be careful not to lose it.
Place the speaker on top of the TV or inside the TV rack so
that the speaker and TV are aligned vertically.
Notes
• Do not place the speaker on top of the TV whose
area is smaller than the bottom area of the speaker.
If placed, the speaker may fall and cause injury.
• Do not place the speaker on top of the TV with an
inclination.
• Placing the speakers too close to a CRT-type TV
may impair the picture color or cause a buzzing
noise. In this case, move the speakers at least
20 cm (8”) away from the TV. This is not an issue
with LCD and plasma TVs.
