PRECAUTIONS

Install the speakers in a cool, dry, clean, stable and horizontal place.

To avoid electric shock, fire, injury, damage to the speakers, and discoloration of the cabinet, install away from windows, heat sources, sources of excessive vibration, dust, moisture, cold, rain, water, falling objects, noise sources (transformers, motors, etc.) and direct sunlight.

Do not insert a hand or object into the port or pick up the speaker by holding the port, as it may cause personal injury or damage to the speaker.

Any time you note distortion, reduce the volume control on your receiver to a lower setting. Never allow your receiver to be driven into “clipping”. Otherwise the speakers may be damaged.

When using a receiver 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 modify or fix the speakers. Contact qualified Yamaha service personnel when any service is needed. The cabi- net should never be opened for any reasons.

Secure placement or installation is the owner’s respon- sibility. Yamaha shall not be liable for any accident caused by improper placement or installation of speak- ers.

ACCESSORIES

Check that the following items are included.

Speaker cable (2 m) x 2 / Front cover x 2

ATTACHING THE FRONT COVER

The speaker and the front cover are packed separately. To attach the front cover, line up the projections (magnets) on the reverse side of the front cover with their corresponding screw heads on the speaker.

Note

When the cover is removed, be sure not to touch the speaker units with your hands or to exert excessive force with tools.

CONNECTION TO YOUR RECEIVER
BEFORE MAKING CONNECTIONS, MAKE SURE THAT THE RECEIVER IS SWITCHED OFF.

When this unit is connected to the receiver, refer also to the owner’s manual supplied with the receiver.

See page 1 for the connection method.

PLACING THE SPEAKERS

Place the speakers on a sturdy, vibration-free surface. You may not be able to obtain good bass quality when the speakers are placed directly on the floor. Put a block, etc. under the speakers.

Better stereo images will be obtained when the speakers are slightly angled in towards the listening position.

Note

Placing this unit too close to a CRT TV set might happen impair picture color or create a buzzing noise. Should this happen, move the speaker away from the TV set.

ATTACHING THE SPEAKER STANDS

You can also use the screw holes on the bottom of the NS-BP400 for installing the speakers on commercially available speaker stands.

A screw with a diameter of 4 mm can be used(Hole depth: 10 mm, 3/8”)

Before installing, please refer to the instruction manual of the speaker stand.

Taking care of the speaker

When you wipe this unit, do not use chemical solvents (ex. alcohol or thinners etc.); this might damage the finish. Clean the cabinet using a soft, dry cloth (such as a Yamaha Unicon cloth). For heavy dirt, use a Yamaha Piano Unicon.

(For polish-finished model) Bumping the surface of the instrument with metal, porcelain, or other hard objects can cause the finish to crack or peel. Use caution.
