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 owners 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 soundtracks 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 unit into the AC main supply. Voltages are 110-120/220-240 V AC, 50/60 Hz.
Standby mode If the POWER switch is set to the ON position and the AUTO STANDBY switch is set to the HIGH or LOW position, this unit turns into the standby mode when no signal is received by this unit for 7 to 8 minutes. In this state, this unit is designed to consume a very small quantity of power.

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.

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.

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.

E-4
Screen
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 power­switching 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).

Adjusting the subwoofer before use

Before using the subwoofer, adjust the subwoofer to obtain the optimum volume and tone balance between the subwoofer and the main speakers by following the procedures described below.

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 amplifiers 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 speakers 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, low­frequency 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.
