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
<Main speakers (NS-M103)>
2-way acoustic-suspension speaker system
<Center speaker (NS-C103)>
2-way 3-speaker bass-reflex speaker system
<Effect speakers (NS-E103)>
Full-range bass-reflex speaker system
<Subwoofer (SW-P30)>
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.
<For SW-P30 only>
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.
<For Europe and Singapore models only>
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.

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.

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.

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

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.
