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. Furthermore, 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.
CAUTION: Read this before operating your unit.
Thank you for selecting this YAMAHA NS-P230/NS-P236 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.
●

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
<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).
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
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 super-
bass 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)
ıÅ
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.
䡵 Placing the center speaker
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.

Automatic power-switching function
If the source being played is stopped and the input signal
is cut off for 7 to 8 minutes, the subwoofer automatically
switches to the standby mode. (When the subwoofer
switches to the standby mode by the automatic power-
switching function, the power indicator lights up in red.)
When you play a source again, the power of the
subwoofer turns on automatically by sensing audio signals
input to the subwoofer.
This function will operate by sensing a certain level of low
frequency input signal. Usually set the AUTO STANDBY
switch to the LOW position. However, if the power is not
switched to ON or STANDBY smoothly, set the switch to
the HIGH position. In the HIGH position, the power will
turn on even with a low level of input signal. But please be
aware that the subwoofer may not switch to the standby
mode when there is an extremely low input signal.
* The power might turn on unexpectedly by sensing noise
from other appliances. If that occurs, set the AUTO
STANDBY switch to the OFF position and use the
POWER switch to switch the power between ON and
OFF manually.
* This function detects the low-frequency components
below 200 Hz of the input signals (i.e., the explosion in
the action movie, the sound of the bass guitar or the
bass drum, etc.).
* The minutes required to switch the subwoofer to the
standby mode might change by sensing noise from
other appliances.
This function is available only when the power of the
subwoofer is on (by pressing the POWER switch).

1 Set the VOLUME control to minimum (0).
2 Turn on the power of all the other
components.
3 Press the POWER switch to the ON position.
* The power indicator on the front panel lights
up in green.
4 Play a source containing low-frequency
components and adjust the amplifier’s
volume control to the desired listening level.
5 Set the HIGH CUT switch to the LOW or
HIGH position.
This subwoofer is designed so that the
optimum tone balance between the subwoofer
and the main speakers is obtained when this
switch is set to the LOW position. The tone
balance may change, however, depending on
the room size, the distance from the subwoofer
to the main speakers, and so on. If necessary,
switch it to the HIGH position.
6 Increase the volume gradually to adjust the
volume balance between the subwoofer and
the main speakers.
Normally, set the control to the level where you
can obtain a little more bass effect than when
this unit is not used. If the desired response
cannot be obtained, adjust the HIGH CUT
switch and the VOLUME control again.
● Once the volume balance between the subwoofer and
the main speakers is adjusted, you can adjust the
volume of your whole sound system by using the
amplifier’s volume control.
However, if you change the main speakers (NX-230P)
to others, you must make this adjustment again.
● For adjusting the VOLUME control and the HIGH CUT
switch, refer to “Frequency characteristics” below.

ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY
(for YST-SW005)
The theory of Yamaha Active Servo Technology has been
based upon two major factors, the Helmholtz resonator and
negative-impedance drive. Active Servo Processing
speakers reproduce the bass frequencies through an “air
woofer”, which is a port or opening in the speaker’s cabinet.
This opening is used instead of, and performs the functions
of, a woofer in a conventionally designed speaker system.
Thus, signals of low amplitude within the cabinet can,
according to the Helmholtz resonance theory, be outputted
from this opening as waves of great amplitude if the size of
the opening and the volume of the cabinet are in the correct
proportion to satisfy a certain ratio.
In order to accomplish this, moreover, the amplitudes within
the cabinet must be both precise and of sufficient power
because these amplitudes must overcome the “load”
presented by the air that exists within the cabinet.
Thus it is this problem that is resolved through the
employment of a new design in which the amplifier supplies
special signals. If the electrical resistance of the voice coil
could be reduced to zero, the movement of the speaker unit
would become linear with respect to signal voltage. To
accomplish this, a special negative-impedance output-drive
amplifier for subtracting output impedance of the amplifier is
used.
By employing negative-impedance drive circuits, the
amplifier is able to generate precise, low-amplitude, low-
frequency waves with superior damping characteristics.
These waves are then radiated from the cabinet opening as
high-amplitude signals. The system can, therefore, by
employing the negative-impedance output drive amplifier
and a speaker cabinet with the Helmholtz resonator,
reproduce an extremely wide range of frequencies with
amazing sound quality and less distortion.
The features described above, then, are combined to be the
fundamental structure of the conventional Yamaha Active
Servo Technology.
Our new Active Servo Technology — Advanced Yamaha
Active Servo Technology — adopted Advanced Negative
Impedance Converter (ANIC) circuits, which allows the
conventional negative impedance converter to dynamically
vary in order to select an optimum value for speaker
impedance variation. With this new ANIC circuits, Advanced
Yamaha Active Servo Technology can provide more stable
performance and improved sound pressure compared with
the conventional Yamaha Active Servo Technology, resulting
in more natural and dynamic bass reproduction.
