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 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 NSM40, NS-C40 and SW-P40 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 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 SW-P40 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 equipment. Never pull the wire
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 a space of at least 20 cm (7-7/8”) above,
behind and on the both sides of the unit. Also, do not
position with the rear panel facing down on the floor or other
surface.
●
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 has a port called “air woofer” which is for
reproducing a super-bass sound.
Be careful not to put a hand or some objects into the port,
otherwise it may give you an electric shock or give this unit
a damage, or cause a fire.
●
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.
Voltages are AC 110/120/220/240V, 50/60 Hz.
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.
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.

Before you make connections, place all speakers in their proper positions respectively. The positioning of speakers are important,
because it controls the whole sound quality of this system.
Position the speakers on the basis of your listening position by following instructions on this section.
English
SETTING UP THE SPEAKERS
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 the main source sound plus the effect sounds. The effect speakers are used for the effect and
surround sounds, and the center speaker is for the 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 in 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.

■ Placing the subwoofer
A
(
: subwoofer,
B
: main speaker)
It is recommended to place the subwoofer on the outside of
either the right or the left main speaker. (See fig. A .) The
placement shown in fig. B 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. A .
Note
There may be a case that you cannot obtain enough superbass sounds from this unit when listening at the middle of the
room. This is because “standing waves” have developed
between two parallel walls and the bass sounds are being
canceled.
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.
6
Use the rubber pads
Put the provided rubber pads at the four corners on the bottom
of the subwoofer to prevent the subwoofer moving due to
vibrations etc.
Mount the effect speakers on a shelf, rack or on the floor
directly, or hang them on the wall.
To mount the effect speakers on a wall
The speakers can be mounted on a wall by using the holes
provided on the speakers’ rear panels.
Fasten screws into a firm wall or wall support as shown in the
diagram, and hang the holes on the rear of the speaker on the
protruding screws.
* Make sure that the screws are caught by a narrow part of
the holes securely.
WARNING:
• Each speaker weighs 1.6 kg (3 lbs. 8 oz.). Do not mount
them on thin plywood or soft wall surface material, as
the screws may come out of the flimsy surface, causing
the speakers to fall down and be damaged, or result in
personal injury.
• Do not fasten 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.

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.
• 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.

When you play a source, the power to 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 responding to a certain level of
low frequency input signal. Increase the output level on
the input source if the automatic power ON function will not
operate, or decrease the level if the automatic power OFF
function will not operate.
* There may be a case that the power turns on
unexpectedly by sensing noise from other appliances. If
it occurs, set the AUTO POWER ON/OFF switch to the
OFF 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 source.
This function is available only when the power of this
unit is on (by setting the POWER switch (6) 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-M40 to
others, you must make this adjustment again.
• For adjusting the VOLUME control and the HIGH CUT
control, refer to “FREQUENCY CHARACTERISTICS” on
the next page.
Note about setting the HIGH CUT control
This system is designed so that the optimum tone balance
between the subwoofer and the main speakers is obtained
when this control is set at the point of 80 Hz. 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 you prefer, turn the HIGH CUT control to set it to a
position where a better tone balance is obtained.

ACTIVE SERVO TECHNOLOGY
The theory of Active Servo Technology is based upon two
major factors, the Helmholtz resonator and negativeimpedance 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.
Highamplitude
bass
sound
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 highamplitude 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.
