USER MANUAL NSB951 YAMAHA

• 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. PRECAUTIONS Taking care of the speaker To maintain the spotless glossy surface of the polished finish, wipe it with a soft, dry cloth. To avoid damage to the finish, do not apply chemical solvents, such as alcohol, benzine, thinner, insecticide, etc. Also, do not use a damp cloth, or any type of cloth that contains chemical solvents, or place a plastic or vinyl sheet on top of the speaker. Otherwise, the finish may peel, the color may fade, or the sheet may stick to the surface. English Information for Users on Collection and Disposal of Old Equipment This symbol on the products, packaging, and/or accompanying documents means that used electrical and electronic products should not be mixed with general household waste.

For more information about collection and recycling of old products, please contact your local municipality, your waste disposal service or the point of sale where you purchased the items. [Information on Disposal in other Countries outside the European Union] This symbol is only valid in the European Union. If you wish to discard these items, please contact your local authorities or dealer and ask for the correct method of disposal.2 En English The grille is detached from the speaker and packed separately. Be careful not to lose it. Place the speakers on a sturdy, vibration-free surface, or 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 front 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. Placing the speakers too close to a CRT-type TV may impair the picture color or cause a buzzing noise. In this case, move the speakers at least 20 cm (8") away from the TV. This is not an issue with LCD and plasma TVs.

PLACING THE SPEAKERS

Speaker layout image Note NS-B951SurroundSubwooferCenter Yamaha speaker stand SPS-900 (option) You can use this unit as a floor stand speaker when installing on an SPS-900. In this case, use screw holes on the bottom of this unit.

• For details about installing, refer to the assembly instruction of SPS-900.

• To avoid accidents resulting from tripping over loose speaker cables, fix them to the floor.

• Do not fasten the speaker on the stand with nails or adhesives, etc. Long time use and vibrations may cause this unit to fall down.

• Do not pinch the cables between the speaker and the stand.

Before making connections, make sure that the amplifier is switched off. ■ CONNECTIONS You need a commercially available speaker cable.

The size and/or material of a speaker cable affects on the sound quality. Therefore, we recommend you purchase a high-quality speaker cable to exert the performance of this unit.

• Connect the + terminals on the amplifier and the speakers using one side of the cable. Connect the – terminals on both components using the other side of the cable.

• Connect one speaker to the left (L) terminals of your amplifier, and another speaker to the right (R) terminals, making sure not to reverse the polarity (+, –). If one speaker is connected with reversed polarity, the sound will be unnatural and lack bass.

• 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.

• The speaker may be damaged if certain sounds are continuously output at high volume level. For example, if sine waves from a test disc, bass sounds from electronic instruments, etc., are continuously output, or when the stylus of a turntable touches the surface of a disc, reduce the volume level to prevent the speaker from being damaged.

• Please refer to the owner’s manual that came with your amplifier or receiver. How to connect: 1 Loosen the knob. 2 Remove 15 mm (5/8") of insulation from each end of the cables, and twist the exposed conductors together neatly and tightly, as shown below. 3 Insert the bare wire into the hole. 4 Tighten the knob and secure the cable. 5 Test the firmness of the connection by pulling the cable lightly at the terminal.
• Do not let the bare speaker wires touch each other as this could damage the speaker and/or the amplifier.• Do not insert the insulation coating into the hole. The sound may not be produced. <Standard connections> When connecting the speaker cable, leave the jumper cables in place.

CONNECTING TO YOUR AMPLIFIER

Red (+)Black (–)Woofer terminalsNS-B951 (R) NS-B951 (L)AmplifierJumper cableAmplifierNS-B951 (R) NS-B951 (L)Tweeter/Mid-range terminals Both SPEAKERS A and B should be selected. When your amplifier has two sets of speaker output terminals. When your amplifier has only one set of speaker output terminals. Remove the jumper cables before connecting. To connect the speaker to the output terminals of the amplifier, two pairs of cables for each of the woofer and the tweeter/mid-range are used instead of standard connections. This type of connection decreases the modulation distortion caused by electric resistance of the cables and driving current of the speakers. Consequently, purer sound quality can be expected. To utilize bi-wired connections, remove the jumper cables from the terminals first, and then connect the woofer and the tweeter/mid- range to the amplifier separately using two pairs of cables. Remove the jumper cables before connecting. When using a banana plug 1 Tighten the terminal knob. 2 Simply insert the banana plug into the terminal.

Banana plug5 En The speaker and the grille are packed separately. To attach the grille, line up the four salients (magnet) on the reverse side of the grille with the four corresponding pegs.

• When the grille is not attached, take care not to touch the speaker units with your hands or to exert excessive force with tools.

• There are magnets on the reverse side of the grille. Do not place the grille close to objects that might be affected by magnets, such as TVs, clocks, magnetic cards, diskettes etc. when you don’t attach it. The port on the back of this unit has a port plug to adjust the bass level. When you want to increase the bass level, detach the port plug.
