Thank you for selecting this YAMAHA NS-P230/NS-P236 Speaker Package.

CAUTION: Read this before operating your unit.

English

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.

Avoid installing the speakers where foreign objects may fall onto

●

them and/or where they may be exposed to liquid dripping or
splashing.
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 reason.

Be sure to read the “TROUBLESHOOTING” section regarding

●

common operating errors before concluding that the speakers
are faulty.

For YST-SW005

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

●

causing damage.

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 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. Further more, do not position with the
rear panel facing down on the floor or other surfaces.

<For U.K. and Europe models>

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.

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

●

(For China, Korean and General models)
The voltage selector switch on
the rear panel of this unit must
be set for your local main
voltage BEFORE plugging this

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.

English

Speaker configuration

<NS-P230>

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

<NS-P236>

This speaker package employs a 7 speaker configuration: 2
main speakers, 2 rear speakers, a center speaker, a rear
center speaker and a subwoofer.
The main speakers emit main source sound. The rear and
rear center speakers emit surround sounds, and the center
speaker emits center sounds (dialog etc.). The subwoofer
emits reinforcing low frequencies on your audio system.

Note
In this speaker package, the same speakers (NX-230P)
are used for the main and rear speakers (and rear
center speaker for NS-P236).

Main L Center Main R

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.

Rear center speaker (for NS-P236):

Precisely between the rear 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.

䡵 Placing the subwoofer

ıÅ

( : Subwoofer, : Main speaker)

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.

䡵 Placing the center speaker

You can place the speaker on top of the TV if the top is flat,
on the floor under the TV, or inside the TV rack . Be sure to
place the speaker in a stable position.
When placing the speaker on top of the TV, to prevent the
speaker from falling, attach the provided fasteners at two
points on the bottom of the speaker and on the top of the
TV.

Notes

● Do not place the speaker on top of a TV whose area

is smaller than the bottom of the speaker. If placed,
the speaker may fall and cause injury.

● Do not place the speaker on top of a TV if the top is

inclined.

● Do not touch the adhesive surface after peeling off

the seal as this will weaken its adhesive strength.

● Thoroughly wipe clean the surface where the

fastener is to be applied. Note that adhesive strength
is weakened if the surface is dirty, oily or wet and
that this may cause the center speaker to fall.
