Thank you for selecting this YAMAHA NS-P320 Speaker Package.

CAUTION: Read this before operating your unit.

●

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 electrical 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 the speakers:

Glass, china, etc.

If glass etc. falls by vibrations and breaks, it may cause personal injury.

A burning candle etc.

If the candle falls by vibrations, it may cause fire and personal injury.

A vessel with water in it

If the vessel falls by vibrations and water spills, it may cause damage to the speakers, and/or you may get an electric shock.

●

Do not place the speakers where foreign objects such as water drips might fall. It might cause a fire, damage to the speakers, and/or personal injury.

●

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.

●

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.

●

As these speakers contain strong magnets (though all of them are magnetically shielded types), avoid placing watches, magnetic tapes, etc. near them. Also, placing the speakers near a TV set may impair picture color. If this happens, move the speakers away from the TV set.

●

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

●

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.

●

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

●

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

●

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 space above, behind and on the 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 a space of at least 20 cm above, behind and on both sides of the unit.

●

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.

●

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.

●

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.

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.

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.

Placing the subwoofer

Å ı

( : 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.

䡵

Placing the center speaker

Place the speaker on TV whose top is flat or on the floor under the TV or inside the TV rack so that it is stabilized.

When placing the speaker on top of the TV, to prevent the speaker from falling down, put the provided fasteners at four points on the bottom of the speaker and the top of the TV.

Peel off the seal

Fastener

Notes

● Do not place the speaker on top of the TV whose area is smaller than the bottom area of the speaker.

If placed, the speaker may drop out causing an injury to you.

●

Do not place the speaker on top of the TV with an inclination.

● 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 drop.

WARNING

Be sure to unplug the subwoofer before setting the

VOLTAGE SELECTOR switch correctly.

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, 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 operates 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 setting the POWER switch (

1

) to

“ON”).

ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY

(for SW-P201)

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, 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.
