Read this before using the speakers.

●

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 electrical shock,

do not expose the speakers to rain or water.

● 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 the speakers:

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 speakers, 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

the speakers, and/or personal injury.

PRECAUTIONS

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.

PRECAUTIONS WHEN POSITIONING THE SPEAKERS

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 speakers to increase

stability:

Be sure to use the stands regardless of where the speakers

are positioned. Attaching the stands included with the

speakers 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 speakers will

not fall over.

OWNER’S MANUAL

U G R

Thank you for selecting this YAMAHA NS-8390 speaker system.

● 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.

● Placing the speakers on the same shelf or rack as the

turntable can result in feedback.

● 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

speakers may be damaged.

●

When using an amplifier with a rated output power higher

than the nominal input power of the speakers, care should

be taken never to exceed the speakers’ maximum input.

●

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.

● 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.
