Frequently Asked Questions - NSB310 YAMAHA

How to connect NS-B310 speakers to an amplifier?

Use a speaker cable stripped to 10 mm. Loosen the screw terminals, insert the stripped wire respecting polarity (+/-) and tighten. Connect the left speaker to the L output and the right speaker to the R output. You can also use banana plugs after removing the terminal caps.

Can the NS-B310 be wall-mounted?

Yes, the speakers come with a wall mounting bracket. Use self-tapping screws (diam. 3.5–4 mm, min. length 20 mm) into a solid wall. Hang the bracket on the screws. The speaker weight is 1.6 kg. Do not mount on plywood or a soft surface.

How to remove the front grille of the speakers?

The grille is held by magnets. Hold the speaker with one hand and gently pull the grille with the other hand. Avoid touching the drivers. Do not place the grille near objects sensitive to magnets (CRT TV, magnetic cards).

What is the recommended amplifier power for these speakers?

The nominal power is 40 W and maximum power is 120 W. Use an amplifier with output power not exceeding 120 W per channel. If distortion occurs, reduce the volume to avoid damaging the speakers.

What to do if the sound is distorted or lacks bass?

Check the polarity of the connections: the (+) and (-) wires must match between the amplifier and each speaker. If a speaker is reversed, the sound will be weak and lack bass. Correct the wiring.

Can the NS-B310 be used with a TV?

Yes, they can be used as front or surround speakers in a home theater system. Place them on each side of the TV. For a CRT TV, keep the speakers at least 20 cm away to avoid interference. No problem with plasma or LCD TVs.

How to maintain the speakers?

Clean with a clean, dry cloth. For stubborn stains, slightly dampen the cloth with water and wring it well. Never use chemical solvents (alcohol, thinners) that could damage the finish.

Are the speakers magnetically shielded?

Yes, they are magnetically shielded type, allowing placement near a TV without distorting the picture (except CRT closer than 20 cm).

What is the warranty period?

YAMAHA offers a 2-year warranty against manufacturing defects, parts and labor, in the European Economic Area and Switzerland. Keep the purchase receipt as proof.

Are speaker cables supplied?

No, no speaker cables are included. You must purchase them separately. Use cable of appropriate gauge (at least 1.5 mm²) for good performance.

■Using as front speakers and surround speakers in a surround system

Position the speakers on both sides of the TV. The positioning of speakers is important, since this dictates the overall sound quality of the surround system. Set up the speakers on the basis of your listening position by following the owner's manual supplied with your amplifier.

And 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.

■To mount the speakers on a wall by using the attached mounting bracket

Fasten screws into a firm wall or wall support as shown in the figure, and hang the holes of the mounting bracket on the protruding screws.

* Make sure that the screws are secured in the narrow sections of the holes.

You can also use the screw holes on the bottom of the speaker for installing the speaker using a commercially available speaker bracket (if you do not use the attached mounting bracket).

Note

Placing this unit too close to a CRT TV set might impair picture color or create a buzzing noise. Should this happen, move the speaker away (more than 20 cm (7-7/8")) from the TV set.

When using a PDP or LCD TV, it would not happen.

WARNING

• NS-B310 weighs 1.6 kg (3 lbs. 8 oz.). Do not mount it on thin plywood or a wall with soft surface material. If mounted, the screws may come out and the speaker may fall. This may damage the speaker, or cause personal injury.
• Do not install the speaker on a wall with nails, adhesives, or any other unstable hardware. Long term use and vibrations may cause it to fall.
  • To avoid accidents resulting from tripping over loose speaker cables, fix them securely to the floor or wall.
