moisture and cold. Avoid sources of humming (transformers,
motors). To prevent fire or electric 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 top of the speakers:
●
Other components, as they might cause damage and/or
discoloration on the surface of the speakers.
●
Burning objects (i.e. candles), as they might cause fire,
damage to the speakers and/or personal injury.
●
Containers with liquid in them, as they might cause electric
shock to the user and/or damage to the speakers.
●
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.
●
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.
●
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.
●
Do not attempt to clean the speakers with chemical solvents as
this might damage the finish. Use a clean, dry cloth.
●
Do not attempt to modify or fix the speakers. Contact qualified
YAMAHA service personnel when any service is needed. The
cabinet should never be opened for any reasons.
●
Be sure to read the “TROUBLESHOOTING” section regarding
common operating errors before concluding that the speakers
are faulty.
For YST-SW45 only
●
Do not operate this unit upside down. It may overheat, possibly
causing damage.
●
Do not use force on switches, controls or connection wires.
When moving this unit, first disconnect the power plug and the
wires connected to other equipments. Never pull the wires
themselves.
●
Since this unit has a built-in power amplifier, heat will radiate
from the rear panel. Place the unit apart from the walls, allowing
20 cm above, behind and on 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.
●
To avoid condensation inside this unit, do not expose this unit to
sudden temperature changes from cold to hot, or do not place
this unit in an environment with high humidity (i.e. a room with a
humidifier). Condensation may cause an electric shock, fire,
and/or damage to this unit.
CAUTION: Read this before operating your unit.
Thank you for selecting this YAMAHA NS-P610 Speaker Package.
●
Do not cover the rear panel of this unit with a newspaper, a

●
To prevent lightning damage, disconnect the AC power plug
when there is an electric storm.
●
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.
●
This unit may be damaged if certain sounds are continuously
outputted at high volume level. For example, if 20 Hz–50 Hz sine
waves from a test disc, bass sounds from electronic instruments,
etc. are continuously outputted, or when the stylus of a turntable
touches the surface of a disc, reduce the volume level to prevent
this unit from being damaged.
●
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.
●
Vibration generated by super-bass frequencies may distort
images on a TV. In such a case, move this unit away from the TV
set.
●
When disconnecting the power cord from the wall outlet, grasp
the plug; do not pull the cord.
●
When not planning to use this unit for a long period (i.e. vacation,
etc.), disconnect the AC power plug from the wall outlet.
VOLTAGE SELECTOR (China and general models only)
The VOLTAGE SELECTOR on the rear panel of this unit must be

main supply. Voltages are 110-120/220-240 V AC, 50/60 Hz.
Standby mode
When this unit is turned off by pressing the STANDBY/ON button
on the front panel, it consumes a small amount of power. This
state is called the standby mode. This unit’s power supply is
completely cut off from the AC line only when the POWER switch
on the rear panel is set in the OFF position or the AC power cord
is disconnected.
These speakers feature a magnetically shielded design, but
there is still a chance that placing them too close to a TV set
might impair picture color. Should this happen, move the
speakers away from the TV set.

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 14 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 HIGH CUT control enables you to adjust the tone
balance between the subwoofer and the main speakers.
● The Automatic power-switching function saves you the
trouble of pressing the STANDBY/ON button to turn the
power on and off.
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.
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 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.

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.
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.
( : Subwoofer, : Main speaker)
ıÅ
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.
Note
In this speaker package, the same speakers (NS-10MMT)
are used for the main and rear speakers.
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.

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 (1)
becomes dim.)
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
(9) 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 (9) switch to the OFF position and use the
POWER (5) 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 pressing the STANDBY/ON (2)
button).

9 AUTO STANDBY (HIGH/LOW/OFF) switch
This switch is originally set to the OFF position. By
setting this switch to the HIGH or LOW position, the
subwoofer’s automatic power-switching function
operates as described below. If you do not need this
function, leave this switch in the OFF position.
* Make sure to change the setting of this switch only
when the STANDBY/ON (2) button is not pressed
in.
0 VOLTAGE SELECTOR switch (China and general
models only)
If the preset setting of the switch is incorrect, set the
switch to the proper voltage range (220V-240V or
110V-120V) of your area.
Consult your dealer if you are unsure of the correct
setting.

1 Set the VOLUME control of the amplifier to
minimum (0).
2 Turn on the power of all the other
components.
3 Press the STANDBY/ON button to turn on
the subwoofer.
4 Play a source and adjust the amplifier’s
volume control to the desired listening level.
5 Adjust the HIGH CUT control to the position
where the desired response can be
obtained.
This system is designed so that the optimum tone
balance between the subwoofer and the main speakers
(NS-10MMT) is obtained when this control is set at 110
Hz. However, the tone balance may change depending
on the room size, the distance from the subwoofer to
the main speakers, etc. So, if you prefer, turn the HIGH
CUT control and set it to a position where a better tone
balance is obtained.
䡵 Adjusting the subwoofer before use
Before using the subwoofer, adjust the subwoofer to obtain the optimum volume and tone balance between the subwoofer and
the main speakers by following the procedures described below.
6 Increase the volume gradually to adjust the
volume balance between the subwoofer and
the main speakers.
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-10MMT
to others, you must make this adjustment again.

ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY
(for YST-SW45)
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.
