FCC INFORMATION (for US customers only)

YAMAHA and the Electronic Industries Association’s

Consumer Electronics Group want you to get the most out of

your equipment by playing it at a safe level. One that lets the

sound come through loud and clear without annoying blaring

or distortion – and, most importantly, without affecting your

sensitive hearing.

Since hearing damage from loud sounds is often

undetectable until it is too late, YAMAHA and the

Electronic Industries Association’s Consumer

Electronics Group recommend you to avoid

prolonged exposure from excessive volume levels.

We Want You Listening For A Lifetime

“NS-P300” is the package number which includes the YAMAHA speaker system NS-M103, NS-C103, NS-E103 and SW-P30.

This speaker package system is designed for use in a multi-channel audio system, for example a home theater system, so the

package includes a pair of main speakers (NS-M103), a center speaker (NS-C103), a pair of effect speakers (NS-E103) and a

subwoofer system (SW-P30).

PROFILE OF THIS SYSTEM

2-way acoustic-suspension speaker system

2-way 3-speaker bass-reflex speaker system

Full-range bass-reflex speaker system

Active Servo Processing Subwoofer System with a

built-in power amplifier

•

This subwoofer system employs YAMAHA Active Servo

Technology which YAMAHA have developed for

reproducing higher quality super-bass sound. (Refer to page

14 for details on Active Servo Technology.)

•

This unit can be added easily to your existing audio system

by connecting to either the speaker terminals or the line

output (pin jack) terminals of the amplifier.

•

The HIGH CUT switch provides you with two positions

(HIGH and LOW) to adjust the tone balance between the

subwoofer and the main speakers.

•

The AUTO STANDBY switch saves you the trouble of

setting the POWER switch to the ON or OFF position.

●

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 it will be exposed to direct

sunlight or excessive humidity.

●

Do not place the speakers where it is 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 TV set.

●

Do not attempt to clean the speakers with chemical

solvents; 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 the speakers.

For canadian customers

To prevent electric shock, match wide blade of plug to wide

slot and fully insert.

This Class B digital apparatus complies with Canadian

ICES–003.

●

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

contact your dealer.

●

Do not use force on switches, controls or connection cords.

When moving the unit, first disconnect the power plug and

the cords connected to other equipment. Never pull the

cords itself.

●

Be sure to read the “TROUBLESHOOTING” section

regarding common operating errors before concluding that

the unit is faulty.

●

When not planning to use this unit for long periods of time

(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 electrical storm.

●

Since this unit has a built-in power amplifier, heat will radiate

from the rear panel. Therefore, place the unit apart from the

walls, allowing enough space above, behind and on the both

sides of the unit to prevent fire and damage. Also, do not

position with the rear panel facing down on the floor or other

surface.

Be sure to allow a space of at least 20 cm above, behind

and on the 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 distortion (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.

This unit is not disconnected from the AC power source as

long as it is connected to the wall outlet, even if this unit

itself is turned off. This state is called the standby mode.

In this state, this unit is designed to consume a very small

quantity of power.

WARNING

TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO

NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.

CAUTION: READ THIS BEFORE OPERATING YOUR UNIT.

After unpacking, check that the following parts are contained.

Speaker cords Velcro strips (for NS-C103)

SUPPLIED ACCESSORIES

English

Before you make connections, place all speakers in their proper positions respectively. The positioning of speakers is important,

because it controls the whole sound quality of this system.

Position the speakers based on your listening position by following instructions in this section.

Speaker configuration

This system employs a 6 speaker configuration: 2 main

speakers, 2 effect speakers, a center speaker and a

subwoofer.

The main speakers are used for main source sound. The effect

speakers are used for effect and 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 the TV and almost the

same height as the TV.

Effect speakers: Behind your listening position, facing

slightly inward. Nearly 1.8 m (approx. 6

feet) up 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” shown

below for a recommended positioning of

the subwoofer.

SETTING UP THE SPEAKERS

It is recommended to place the subwoofer on the outside of

either the right or the left main speaker. (See fig. .) The

placement shown in fig. 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. To prevent this, face the

subwoofer system obliquely to the wall as shown in fig. .

Note

There may be a case that you cannot obtain enough super-

bass sounds from this unit when listening at the middle 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.

■ Placing the subwoofer

( : subwoofer, : main speaker)

■ Mounting the center speaker

Place the center speaker on the TV, on the floor under the TV

or in 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 velcro strips at two

points on both bottom of the speaker and top of the TV.

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 down and that injures you.

• Though this speaker is a magnetically shielded type,

there may be some influence on a TV picture depending

on the type of TV or the placement of the speaker. In

such a case, place the speaker apart from the TV so that

there is no influence on TV picture.

English

■ Mounting the effect speakers

Mount the effect speakers on a shelf, rack or floor, or hang

them on the wall.

To mount the effect speakers on a wall

Mount the speakers in either of the two configurations shown in

the following figures by using the holes provided on the

speakers’ rear panels.

Fasten wood screws onto a firm wall or wall support as shown

in the following figure, and set the mounting holes on the

protruding screws.

* Make sure that the screw is caught securely at a narrow part

of the hole.

For the upright mounting, only one hole is provided.

As for the side-long mounting, two holes are provided. Be sure

to use these two holes as a set.

WARNING:

• Each speaker weighs 1.4 kg (3 lbs. 1 oz.). Do not mount

them on thin plywood or soft wall surface material. If

mounted, the screws may come out of the flimsy surface

and the speakers may fall down. That damages the

speakers or causes personal injury.

• Do not install the speakers to wall with nails, adhesives,

or other unsound hardware. Long-term use and

vibrations may cause them to fall down.

• To avoid accidents resulting from tripping over loose

speaker cords, fix them to the wall.

Automatic power-switching function

When you play a source, the power of this unit turns on

automatically by sensing audio signals input to this unit.

This unit turns into the standby mode automatically if the

source being played is stopped or the input signal is cut off

for several minutes.

This function will operate by sensing a certain level of low

frequency input signal. Its sensitivity is high in the HIGH

position and low in the LOW position of the AUTO

STANDBY switch. Set this switch to whichever position

you like. In the HIGH position, the power will turn on even

with a low level of input signal, but on the other hand this

unit may not turn into the standby mode when there is an

input signal even if its level is extremely low.

* There may be a case that the power turns on

unexpectedly by sensing noise from other appliances. If

it occurs, set the AUTO STANDBY switch to the OFF or

LOW position.

* The level of low frequency input signal differs with each

source, and each different part on the same source. So,

this function may not operate properly depending on

some sources.

This function is available only when the power of this

unit is on (by setting the POWER switch (

8) to “ON”).

Notes

•

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 only the amplifier’s

volume control.

However, if you change the main speakers NS-M103 to

others, you must make this adjustment again.

•

For adjusting the VOLUME control and the HIGH CUT

switch, refer to “FREQUENCY CHARACTERISTICS” shown

below.

Note about setting the HIGH CUT switch

This system 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. However, the tone

balance may change depending on the room size, the distance

from the subwoofer to the main speakers, and so on.

So, if necessary, switch it to the HIGH position.

ADJUSTMENT BEFORE USING THE SUBWOOFER

Before using the subwoofer, make an adjustment on the subwoofer to obtain the optimum volume and tone balance between the

subwoofer and the main speakers by following the procedures shown below.

The theory of Active Servo Technology is 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 output

from this opening as waves of great amplitude if the

design is such that 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 design in which the amplifier functions to

supply 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, and,

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, and 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 Active Servo Technology.

Turn the VOLUME control to right.

Connect them securely.

Connect them correctly, that is to say L (left)

to L, R (right) to R, “+” to “+” and “–” to “–”.

Play a source sound with bass frequencies.

Set the HIGH CUT switch to the “HIGH”

position.

Re-position the subwoofer or break up the

parallel surface by placing bookshelves etc.

along the walls.

Set the POWER switch to the ON position.

Set the AUTO STANDBY switch to the

“HIGH” or “LOW” position.

Set the AUTO STANDBY switch to the

“HIGH” position.
