OWNER’S MANUAL

NS-M515

Thank you for selecting this YAMAHA NS-M515 speaker system.

PRECAUTIONS

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.

● 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 speaker.

Speaker System

PLACING THE SPEAKERS

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

■ Using as front effect or effect speakers

Mount the speakers on a wall or place the speakers on a
shelf. Determine the best position by following the owner’s
manual supplied with your amplifier.

Note
This speaker features a magnetically shielded design,
but there is still a chance that placing it too close to a
TV set might impair picture color. Should this happen,
move the speaker away from the TV set.

mounted, the screws may come out of the flimsy
surface and the speaker may fall. This damages the
speaker or causes personal injury.

adhesives, or any other unstable hardware. Long­term use and vibrations may cause it to fall.
