NS-90
Read these precautions carefully before using your 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. To clean, wipe with a dry, soft cloth.
●
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 speaker where it is liable to be knocked over or
struck by falling objects. Stable placement will also ensure better
sound performance.
●
Placing the speakers on the same shelf or rack as the turntable
can result in feedback.
●
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 speaker.

PRECAUTIONS
OWNER’S MANUAL
English
PLACING THE SPEAKERS
Place the speakers on a sturdy, vibration-free surface, on a wellbuilt stand.
■ Using as 2ch stereo speakers
Better stereo images will be obtained when the speakers are
slightly angled in towards the listeners.
■ Using as main speakers in a multi channel
system
Position the speakers on both sides of the TV. The positioning of
speakers is important, because it controls the whole sound quality
of a multi channel system. Set up the speakers on the basis of your
listening position by following the owner’s manual supplied with
your amplifier.
