Precautions

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. Do not attempt to clean the speakers with chemical
solvents as this might damage the finish. Use a clean,
dry cloth.

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.

For NS-SW20

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.

Precautions

• VOLTAGE SELECTOR
(For China, Korea, Asia and General models)
The voltage selector switch on the rear panel of this
unit must be set to your local main voltage BE­FORE plugging this unit into the AC main supply.
Voltages are 110-120/220-240 V AC, 50/60 Hz.

This unit is not disconnected from the AC power
source as long as it is connected to the wall outlet, even
if this unit itself is turned off. In this state, this unit is
designed to consume a very small quantity of power.

For U.K. customers

If the socket outlets in the home are not suitable for the
plug supplied with this appliance, it should be cut off and
an appropriate 3 pin plug fitted. For details, refer to the
instructions described below.

Note: The plug severed from the mains lead must be
destroyed, as a plug with bared flexible cord is hazardous
if engaged in a live socket outlet.

SPECIAL INSTRUCTIONS FOR U.K. MODEL

IMPORTANT:

THE WIRES IN MAINS LEAD ARE COLOURED
IN ACCORDANCE WITH THE FOLLOWING
CODE:

Installing the speakers

Before you connect the speakers, place each speaker in
its respective location. Speaker positioning is very
important as it affects the overall sound quality of the
system. Place the speakers in locations that will
optimize the sound quality at your listening position.
Refer to the illustration.

The position of the subwoofer is not as critical as the
position of the other speakers because sub-bass
sounds are not very directional. Refer to “Installing the
subwoofer” on page 2 for more information.

Note

• 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.

Installing the speakers

Installing the front, center, and surround speakers

Front speakers: Place the two front speakers on the

left and right sides of the TV facing directly forward.

Surround speakers: Place the left and right

surround speakers behind your listening position,
facing slightly inward.

The front and surround speakers can be placed on a
flat surface or wall- mounted.
See “Wall-mounting the speakers” for more
information.

Center speaker: Place the center speaker centrally

between the front speakers, facing directly forward.

Installing the subwoofer

Place the subwoofer on the outside of either the right
or the left front speaker, as shown in A and B.

AB

Wall-mounting the speakers

You can mount the speakers on the wall as follows.

1 Install screws into a solid wall or wall support

as shown below. Use 3.5 to 4 mm (1/8")
diameter self-tapping screws.

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.

Note: Standing waves
may make it difficult to
hear bass sounds here.

Subwoofer Front speaker

The placement shown in C is also possible, however, if
the subwoofer is placed directly facing a wall and your
listening position is in the center of the room, you may
not be able to obtain enough bass sound from the
subwoofer. This is because “standing waves” are
forming between the two parallel walls and cancelling
out the bass sounds. In this case, position the
subwoofer at an angle to the wall. It may be necessary
to break up parallel wall surfaces by placing
bookshelves, etc., along them.

War nin gs

• NS-B20 speaker weighs 0.48 kg (1.06 lbs.) and
NS-C20 speaker weighs 0.68 kg (1.50 lbs.). Do not
mount the speakers on thin plywood or on a wall
with a soft surface material. Otherwise, the screws
may pull out of the surface and the speakers may fall,
possibly damaging the speakers or causing personal
injury.

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

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

• Mount the speakers in a wall location that will be
unlikely to result in injury to an individual’s head.
