●

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

●

Install the speakers 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 electric shock, do not expose the
speakers to rain or water.

●

To prevent the enclosure from warping or discoloring, do not
place the speakers where they will be exposed to direct sunlight
or excessive humidity.

●

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

●

Other components, as they might cause damage and/or
discoloration on the surface of the speakers.

●

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

●

Containers with liquid in them, as they might cause electric
shock to the user and/or damage to the speakers.

●

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.

●

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

●

Secure placement or installation is the owner’s responsibility.
YAMAHA shall not be liable for any accident caused by improper
placement or installation of speakers.

●

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 speakers may be damaged.

●

When using an amplifier 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 clean the speakers with chemical solvents as
this might damage the finish. Use a clean, dry cloth.

●

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

●

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

For YST-SW105 only

●

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

●

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

●

Since this unit has a built-in power amplifier, heat will radiate
from the rear panel. Place the unit apart from the walls, allowing
enough spaces above, behind and on both sides of the unit to
prevent fire or damage. Furthermore, do not position with the
rear panel facing down on the floor or other surfaces.

<For U.K. and Europe models only>

Be sure to allow spaces of at least 20 cm above, behind and on
both sides of the unit.

●

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

CAUTION: Read this before operating your unit.

Thank you for selecting this YAMAHA NS-P620 Speaker Package.

●

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

●

Do not plug in this unit to a wall outlet until all connections are
completed.

●

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

●

To prevent lightning damage, disconnect the AC power plug
when there is an electric storm.

●

Super-bass frequencies reproduced by this unit may cause a
turntable to generate a howling sound. In such a case, move this
unit away from the turntable.

●

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

●

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

●

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

●

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

●

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

●

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

Standby mode
When this unit is turned off by pressing the STANDBY/ON button
on the front panel, it consumes a small amount of power. This
state is called the standby mode. This unit’s power supply is
completely cut off from the AC line only when the POWER switch
on the rear panel is set in the OFF position or the AC power cord
is disconnected.

These speakers feature a magnetically shielded design, but
there is still a chance that placing them too close to a TV set
might impair picture color. Should this happen, move the
speakers away from the TV set.

Active Servo Processing Subwoofer System with a
built-in power amplifier

● This subwoofer system employs Advanced YAMAHA
Active Servo Technology which YAMAHA has developed
for reproducing higher quality super-bass sound. (Refer to
page 14 for details on Advanced YAMAHA Active Servo
Technology.) This super-bass sound adds a more
realistic, theater-in-the-home effect to your stereo system.

system by connecting to either the speaker terminals or the
line output (pin jack) terminals of the amplifier.

● The HIGH CUT control enables you to adjust the tone
balance between the subwoofer and the main speakers.

● The Automatic power-switching function saves you the
trouble of pressing the STANDBY/ON button to turn the
power on or turn it to the STANDBY mode.

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:

Blue: NEUTRAL
Brown: LIVE

As the colours of the wires in the mains lead of this apparatus
may not correspond with the coloured markings identifying the
terminals in your plug, proceed as follows: The wire which is
coloured BLUE must be connected to the terminal which is
marked with the letter N or coloured BLACK. The wire which is
coloured BROWN must be connected to the terminal which is
marked with the letter L or coloured RED. Making sure that
neither core is connected to the earth terminal of the three pin
plug.

䡵 Placing the subwoofer

It is recommended to place the subwoofer on the outside of
either the right or the left main speaker. (See fig. Å .) The
placement shown in fig. ı is also possible, however, if the
subwoofer system is placed directly facing the wall, the
bass effect may die because the sound from it and the
sound reflected by the wall may cancel out each other. To
prevent this from happening, face the subwoofer system at
an angle as shown in fig. Å.

Note

There may be a case that you cannot obtain enough super­bass sounds from the subwoofer when listening in the
center of the room. This is because “standing waves” have
been developed between two parallel walls and they cancel
the bass sounds.
In such a case, face the subwoofer obliquely to the wall. It
also may be necessary to break up the parallel surfaces by
placing bookshelves etc. along the walls.

Use the nonskid pads

Put the provided nonskid pads at the four corners on the
bottom of the subwoofer to prevent the subwoofer from
moving by vibrations etc.

( : Subwoofer, : Main speaker)

SETTING UP THE SPEAKERS

Before making connections, place all speakers in their respective positions. The positioning of the speakers is important
because it controls the whole sound quality of this system.
Place the speakers depending on your listening position by following the instructions below.

Speaker configuration

This speaker package employs a 6 speaker configuration: 2
main speakers, 2 rear speakers, a center speaker and a
subwoofer.
The main speakers are used for main source sound. The
rear speakers are used for surround sounds, and the center
speaker is for center sounds (dialog etc.). The subwoofer is
for reinforcing low frequencies on your audio system.

Note
In this speaker package, the same speakers (NS­10MMT) are used for the main and rear speakers.

Placing speakers

Main speakers: On both sides of and at approximately

the same height as the TV set.

Rear speakers: Behind your listening position, facing

slightly inward. About 1.8 m (approx. 6
feet) from the floor.

Center speaker: Precisely between the main speakers.

Subwoofer: The position of the subwoofer is not so

critical because low bass tones are not
highly directional.
Refer to “Placing the subwoofer” below
for a recommended positioning of the
subwoofer.
