●

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.

For SW-P201 only

● Never open the cabinet. If something drops into the set,

contact your dealer.

● Do not use force on switches, controls or connection

wires. When moving the unit, first disconnect the power

plug and the wires connected to other equipments.

Never pull the wires themselves.

● Be sure to read the “TROUBLESHOOTING” section

regarding common operating errors before concluding

that the unit is faulty.

CAUTION: Read this before operating your unit.

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

● 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.

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.

● VOLTAGE SELECTOR

(General model only)

The VOLTAGE SELECTOR on the

rear panel of this unit must be set

for your local main voltage

BEFORE plugging into the AC

main supply.

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 12 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.

● This subwoofer can be easily added to your existing

audio system by connecting to either the speaker

terminals or the line output (pin jack) terminals of the

amplifier.

● The AUTO STANDBY switch saves you the trouble of

setting the POWER switch to the ON or OFF position.

The speaker package “NS-P320” is designed for use in a

multi-channel audio system such as a home theater system.

The package includes two NS-M104 speaker systems, two

NS-E104 speaker systems, one NS-C104 speaker system

and one SW-P201 subwoofer system.

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.

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.

E-3

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.

( : 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.

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.

volume control to the desired listening level.

䡵 Adjusting the subwoofer before use

Before using the subwoofer, adjust the subwoofer to obtain the optimum volume balance between the subwoofer and the main

speakers by following the procedures described below.

Rear panel

5 Increase the volume gradually to adjust the

volume balance between the subwoofer and

the main speakers.

Note: It is recommended to set the

VOLUME control to the middle

position when using all the

speakers of this package in a 5.1-

channel home theater system.

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 NS-M104 to

others, you must make this adjustment again.

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, 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.
