●
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-P220 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.
<For U.K. and Europe models only>
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-P220” is designed for use in a
multi-channel audio system such as a home theater system.
The package includes two pairs of main/rear speakers (NX-
220P), a center speaker (NX-C220) and a subwoofer
system (SW-P201).
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.
3
m 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)

Å
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 (NX-220P) 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.

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.
