YAMAHA NS-F40 (01) PDF DOCUMENT

Please read the following operating precautions before use. Yamaha will not be held responsible for any damage and/or injury caused by not following the cautions below.

1. To assure the finest performance, please read this manual carefully. Keep it in a safe place for future reference.

2. Install the speakers in a cool, dry, clean place – away from windows, sources of heat, sources of excessive vibration, dust, moisture or cold. Avoid sources of electrical humming (e.g., transformers and motors). To prevent fire or electric shock, do not expose the speakers to rain or water.

3. To prevent the enclosure from warping or discoloring, do not expose the speakers to direct sunlight or excessive humidity.

4. Avoid installing the speakers where foreign objects may fall onto them and/or where they may be exposed to liquid dripping or splashing.

5. Do not place the following objects on top of the speakers:

– Other components, as they might damage or discolor the surface of the speakers.

– Burning objects (e.g., candles), as they might cause fire, damage to the speakers or personal injury.

– Containers of liquid, as they might spill and cause electric shock to the user or damage to the speakers.

6. 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.

7. Placing the speakers on the same shelf or rack as the turntable can result in feedback.

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

9. When using an amplifier with a rated output power higher than the nominal input power of the speakers, care should be taken not to exceed the maximum input of the speakers.

10. When you clean the unit, use a clean, dry and soft cloth (such as cloth for glasses).

11. Do not attempt to modify or fix the speakers. Contact qualified Yamaha service personnel when service is needed. The cabinet should never be opened for any reason.

12. Be sure to read the “Troubleshooting” section regarding common operating errors before concluding that the speakers are faulty.

13. Secure placement or installation is the owner’s responsibility. Yamaha is not liable for accidents caused by improper placement or installation of speakers.

Caution on Speaker Stability: 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 ensure its stability. For safe use:

– 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.

Vibrations or jolts may cause the speaker to fall over. For safety reasons, using commercially-available products that increase stability (metal fittings or chains, etc.) is recommended.

WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.

1. Do not operate this unit upside down. It may overheat, possibly causing damage.

2. Do not use excessive force on switches, controls or connection wires. When moving this unit, first disconnect the power plug and the wires connected to other equipment. Never pull the wires themselves.

3. Never put a hand or a foreign object into the port located on the right side of this unit. When moving this unit, do not hold the port, as it might cause personal injury and/or damage to this unit.

4. Since this unit has a built-in power amplifier, heat radiates from the rear panel. Place the unit away from walls, allowing at least 20 cm (8″) of space above, behind and on both sides of the unit to prevent fire or damage. Furthermore, do not position the unit with the rear panel facing down on the floor or other surfaces.

5. When using a humidifier, be sure to avoid condensation inside this unit by allowing enough space around the unit and avoiding excess humidification. Condensation might cause fire, damage to the unit, and/or electric shock.

6. Do not cover the rear panel of this unit with a newspaper, tablecloth, curtain, etc. to avoid obstructing heat radiation. If the temperature inside the unit rises, it may cause fire, damage to the unit, or personal injury.

7. Do not plug this unit into a wall outlet until all connections are complete.

8. The voltage to be used must match that specified on the rear panel. Using this unit with a voltage higher than specified is dangerous and may cause fire, damage to the unit, and/or personal injury. Yamaha is not responsible for damage resulting from use of this unit with a voltage other than specified.

9. Super-bass sound reproduced by this unit may cause a turntable to generate audio feedback. In this case, move the unit away from the turntable.

10. This unit may be damaged if certain sounds are continuously output at high volume level. For example, if 20 Hz-50 Hz sine waves from a test disc or bass sounds from an electronic instrument, etc. are continuously output, or if a turntable stylus touches the surface of a disc, reduce the volume level to prevent the unit from being damaged.

11. If you hear distorted noise (i.e., unnatural, intermittent “rapping” or “hammering” sounds) from this unit, reduce the volume level. Extremely loud movie soundtrack low frequency, bass-heavy sounds, or similarly loud popular music passages can damage this unit.

12. Vibration generated by super-bass sound may distort images on a TV. In this case, move the unit away from the TV set.

13. When disconnecting the power cord from the wall outlet, grasp the plug; do not pull the cord.

14. When you plan not to use this unit for a long period of time (i.e. vacation, etc.), disconnect the AC power plug from the wall outlet.

15. Install this unit near the wall outlet and where the AC power plug can be reached easily.

This applies to China, Korea, Asia, and General models. The voltage selector switch on the rear panel of the NS-SW40 subwoofer must be set to your local main voltage BEFORE plugging the unit into the AC main supply. The selectable voltages are 110-120/220-240 V AC, 50/60 Hz.

Warning: Disconnect the power cable before changing the VOLTAGE SELECTOR setting.

Please make sure that all parts are included in the package. Pay attention not to drop the bases when you take them out of the box.

The package contains:

– Front speaker (NS-F40) x2

– Center speaker (NS-C40) x1

– Surround speaker (NS-B40) x2

– Subwoofer (NS-SW40) x1

– Screw x10 (For the front speakers)

– Non-skid pads (24 pcs.) x1 (For the center and surround speakers, including 12 spare pads)

– Subwoofer cable 5 m (16 ft.) x1

– Speaker cable 24.5 m (80 ft.) x1

Caution Before Assembling:

– Assemble the speakers on top of soft material, such as a carpet, on a level surface.

– Do not grab the grilles on the front panel of the speakers while handling them, as the grilles may be crushed.

– Use only the specified screws supplied in the package.

– Keep screws out of reach of children.

– Tighten the screws firmly so the speaker does not get shaky.

– Do not insert your fingers into any gaps between movable surfaces to avoid injury.

– You must assemble the speaker top, bottom, and base together; you cannot use only the speaker top.

Note: You will need a Phillips (+) screwdriver with a shaft length of 80 mm (3-1/8″) or more.

Part 1: Attach the Base to the Bottom

1. Insert the three projections on the Base into the three holes on the lower end surface of the Bottom section. Make sure the notch on the Base faces the same direction as the rear panel of the Bottom (which has a groove for the speaker cable).

2. Insert four screws from the underside of the Base to attach it to the Bottom. Finger-tighten each screw alternately, then tighten all of them securely.

Hint: You can use the packing polystyrene foam to support the Bottom section during assembly.

Part 2: Attach the Top to the Bottom

1. Place the assembled Bottom and Base on the floor.

2. Place the Top section on the Bottom section so that the Top is slightly toward the front by approximately 15 mm (5/8″).

3. Slide the Top slowly toward the rear until it stops and the rear panel of the Top aligns with the rear of the Bottom.

4. Attach the Bottom to the Top by using a Phillips screwdriver to securely tighten the supplied screw. Rotate approximately twelve times clockwise.

Speaker positioning is very important as it affects the overall sound quality. Place the speakers in locations that will optimize the sound quality at your listening position.

Note on TV Placement: Placing speakers too close to a CRT-type TV may impair picture color or cause buzzing. Move the speakers at least 20 cm (8″) away from the TV. This is not an issue with LCD and plasma TVs.

Front speakers (NS-F40): Place the two front speakers on the left and right sides of the TV, facing directly forward.

Center speaker (NS-C40): Place the center speaker centrally between the front speakers, facing directly forward.

Surround speakers (NS-B40): Place the left and right surround speakers behind your listening position, facing slightly inward.

Installing the subwoofer (NS-SW40): The position of the subwoofer is not as critical as the other speakers. Place the subwoofer on the outside of either the right or the left front speaker. If the subwoofer is placed directly facing a wall and your listening position is in the center of the room, you may not get enough bass sound due to “standing waves”. In this case, position the subwoofer at an angle to the wall or break up parallel wall surfaces by placing bookshelves, etc., along them.

You can mount the center (NS-C40) and surround (NS-B40) speakers on a wall.

Warning:

– Do not mount speakers on thin plywood or a wall with a soft surface. The screws may pull out, causing the speakers to fall.

– Do not affix speakers to a wall using nails, adhesives, or unstable hardware. Long-term use and vibration may cause them to fall.

– To avoid accidents from tripping over loose speaker cables, affix the cables to the wall.

– Mount speakers in a location where they will not likely result in injury to an individual’s head.

– If you are unsure of a safe installation method, consult a professional installer or a building contractor.

Installation Steps:

1. Install commercially available screws into a solid wall or wall support. Use 3.5 to 4 mm (1/8″) diameter self-tapping screws. The screw head should protrude from the wall.

2. Hang each speaker by its keyhole slots onto the protruding screws.

Note: Make sure the shaft of the screw is seated in the narrow part of the keyhole slot. Otherwise, the speaker may fall.

Caution: Make sure the power cables for the subwoofer and your other AV components are disconnected from AC wall outlets before making any connections.

Preparing the Speaker Cables:

1. Cut the included 24.5-meter (80 ft.) speaker cable to make five cables of suitable lengths for the front, center, and surround speakers.

2. Remove about 10 mm (3/8″) of insulation from the end of each speaker cable.

3. Twist the bare wires tightly so the individual strands are not splayed.

Note: Make speaker cables as short as possible. Do not bundle or roll up excess cable. Be careful not to trip on the cables.

Operating the Speaker Terminals (Center and Surround Speakers):

1. Press and hold the terminal tab.

2. Insert the bare wire. Make sure the terminal is gripping the bare wire, not the insulation.

3. Release the tab so that it closes securely on the bare wire.

4. Test the security of the connection by pulling gently on the cable.

Note: Make sure the bare wires do not touch each other, as this could damage the speaker or the amplifier.

Connecting the Front Speakers (NS-F40):

1. After connecting the cable to the terminals on the Bottom section, fit the cable into the groove on the rear panel of the Bottom.

2. After the cable is fit in place down to the Base, pass the cable through the hole in the Base. Pull the cable gently from the underside of the Base and pass it through the notch on the Base.

Connecting to the Amplifier:

Connect each speaker to the appropriate speaker terminals on your amplifier. Make sure you connect with the correct polarity: positive (+) to positive (+) and negative (-) to negative (-). If crossed, the sound will be unnatural and lack bass. In your AV receiver’s speaker size settings, specify small (or “S”) for all of the NS-PA40 speakers.

Caution: When moving a front speaker, grasp both the Base and the Bottom. If a cable comes off a notch, affix it using adhesive tape. Ensure children do not lean on the speaker to prevent it from tipping over.

Connecting Power Cables:

Once you’ve completed all speaker and subwoofer connections, plug the subwoofer, amplifier, and your other AV components into suitable AC wall outlets. Remember to remove any protective sheet from the unit before use.

NS-SW40 Subwoofer Rear Panel Controls:

1. Power indicator: Lights up when the POWER switch is set to ON.

2. INPUT jack: Input jack for connecting the line-level subwoofer output on your amplifier.

3. VOLUME control: Adjusts the subwoofer volume. Turn clockwise to increase, counterclockwise to decrease.

4. POWER switch: Set to ON to turn the subwoofer on, OFF to turn it off.

5. VOLTAGE SELECTOR (China, Korea, Asia, and General models): Ensure this is set to the correct voltage for your area (110–120/220–240 V AC, 50/60 Hz). Ask your dealer if you are not sure.

Setting the Subwoofer Volume:

The first time you use the subwoofer, you need to set the volume balance between the subwoofer and the front speakers.

1. Turn on your other AV components.

2. Set the subwoofer’s VOLUME control to minimum (0).

3. Set the subwoofer’s POWER switch to ON. The power indicator will light up.

4. Play an audio source that contains low-frequency bass sounds. Set the amplifier’s volume control to a suitable level.

5. Turn the subwoofer’s VOLUME control up gradually until you achieve a good balance between the subwoofer and the other speakers.

Note: Once the subwoofer volume is set, you can leave its VOLUME control and use your amplifier’s volume control to adjust the entire system’s volume. If you replace the front speakers, you will need to re-adjust the subwoofer’s volume.

If there is no sound from your front (NS-F40), center (NS-C40), or surround (NS-B40) speakers, the speaker cables may not be connected properly. Please make sure the speaker cables are connected properly.

If the sound is very quiet, the speaker cables may not be connected properly. Make sure the speaker cables are connected with the correct polarity: L (left) to L, R (right) to R, “+” to “+” and “-” to “-”.

If the subwoofer does not work even with the POWER switch on, the power cable may not be connected properly. Set the POWER switch to OFF, then make sure the power cable is connected properly before turning it back ON.

If there is no sound from the subwoofer, check the following:

– The VOLUME control is set to 0. Turn up the VOLUME control.

– The subwoofer cable is not connected properly. Make sure the subwoofer cable is connected properly.

If the subwoofer sounds too quiet, there are two possible causes:

1. The source material doesn’t contain much bass. Try playing a source material that contains more bass.

2. Bass sounds are being cancelled out by standing waves. Reposition the subwoofer, or break up parallel wall surfaces by placing bookshelves or other large objects along the wall.
