YAMAHA will not be held responsible for any damage
and/or injury caused by not following the cautions below.
● To assure the finest performance, please read this
manual carefully. Keep it in a safe place for future
reference.
● Install this unit 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 this unit to rain or water.
● Never open the cabinet. If something drops into the set,
contact your dealer.
● The voltage to be used must be the same as that
specified on the rear panel. Using this unit with a higher
voltage than specified is dangerous and may cause a
fire and/or electric shock.
● To reduce the risk or fire or electric shock, do not expose
this unit to rain or moisture.
● 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 wires themselves.
● When not planning to use this unit for a long period (i.e.
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 spaces 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.
Be sure to allow spaces of at least 20 cm above, behind
and on both sides of the unit.
● Do not cover the rear panel of this unit with a
newspaper, a tablecloth, a curtain, etc. in order not to
obstruct heat radiation. If the temperature inside the unit
rises, it may cause fire, damage to the unit and/or
personal injury.
●
Do not place small metallic objects on this unit.
Otherwise, the object may fall, possibly causing an injury.
● Do not place the following objects on this unit:
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 unit, and/or you may get an
electric shock.
● Do not place this unit where foreign objects such as
water drips might fall. It might cause a fire, damage to
this unit, and/or personal injury.
● Never place a fragile object near the YST port of this
unit. If the object falls or drops by the air pressure, it may
cause damage to the unit and/or personal injury.
● Never put a hand or a foreign object into the YST port
located on the front of this unit. When moving this unit,
do not hold the port as it might cause personal injury
and/or damage to this unit.
● Never open the cabinet. It might cause an electric shock
since this unit uses a high voltage. It might also cause
personal injury and/or damage to this unit.
●
When using a humidifier, be sure to avoid condensation
inside this unit by allowing enough spaces around this unit
or avoiding excess humidification. Condensation might
cause a fire, damage to this unit, and/or electric shock.
● 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.
● Do not attempt to clean this unit with chemical solvents
as this might damage the finish. Use a clean, dry cloth.
● Be sure to read the “TROUBLESHOOTING” section
regarding common operating errors before concluding
that the unit is faulty.
● 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.
Standby mode
When this unit is turned off by pressing the STANDBY/ON
button on the front panel, this unit 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 is set in the OFF
position or the AC power cable is disconnected.
This unit features a magnetically shielded design, but
there is still a chance that placing it too close to a TV set
might impair picture color. Should this happen, move this
unit away from the TV set.
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.
CAUTION: Read this before operating your unit.

FEATURES
● This subwoofer system employs Advanced
YAMAHA Active Servo Technology which YAMAHA
has developed for reproducing higher quality
super-bass sound. (Refer to page 18 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.
● For the effective use of the subwoofer, the
subwoofer’s super-bass sound should be matched
to the sounds of your main speakers. You can
create the best sound quality for various listening
conditions by using the HIGH CUT control and the
PHASE button.
● You can make setting changes and adjustments for
the subwoofer by using the remote control without
moving from your listening position.
● The Automatic power-switching function saves you
the trouble of pressing the STANDBY/ON button to
turn the power on and off.
● You can select bass effect suitable for the source
by using the B.A.S.S. button.
● The use of the H.P.F. OUTPUT terminals for
connecting with the amplifier is effective for
improving sound quality of your speaker system.
This connection prevents sound output from the
main speakers from muddying by filtering out low
frequencies of input signals to be sent to the main
speakers which are not suitable for reproducing
low frequencies.
QD-Bass Technology
QD-Bass (Quatre Dispersion Bass) technology uses
square, pyramid-shaped reflective plates to radiate the
sound in four horizontal directions.

E-3
PLACEMENT
One subwoofer will have a good effect on your audio
system, however, the use of two subwoofers is
recommended to obtain more effect.
If using one subwoofer, it is recommended to place it on the
outside of either the right or the left main speaker. (See fig.
Å.) If using two subwoofers, it is recommended to place
them on the outside of each main speaker. (See fig. ı.)
The placement shown in fig. Ç 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 in fig. Å or ı.
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.

Notes
● Some amplifiers have line output terminals labelled PRE
OUT. When you connect the subwoofer to the PRE OUT
terminals of the amplifier, make sure that the amplifier
has at least two sets of PRE OUT terminals. If the
amplifier has only one set of PRE OUT terminals, do not
connect the subwoofer to the PRE OUT terminals.
Instead, connect the subwoofer to the speaker output
terminals of the amplifier. (Refer to pages 6 and 7.)
● When connecting to a monaural line output terminal of
the amplifier, connect the L/MONO INPUT2 terminal.
● When connecting to line output terminals of the amplifier,
other speakers should not be connected to the OUTPUT
terminals on the rear panel of the subwoofer. If
connected, they will not produce sound.

Connecting to the LFE (INPUT3) terminal(s)
If your amplifier can cut off high frequencies from the signals for sending to the
subwoofer, connect the amplifier to the subwoofer’s LFE (INPUT3) terminal(s). This
will bring you higher sound quality because the signal routing in the subwoofer is
shortened bypassing the built-in HIGH CUT circuit.

Connecting to the INPUT1/OUTPUT terminals of the subwoofer
For connections, keep the speaker cables as short as
possible. Do not bundle or roll up the excess part of the
cables. If the connections are faulty, no sound will be heard
from the subwoofer or the speakers, or both of them. Make
sure that the + and – polarity markings of the speaker
cables are observed and set correctly. If these cables are
reversed, the sound will be unnatural and lack bass.
How to Connect:
Red: positive (+)

Connecting to H.P.F. OUTPUT terminals
The use of the H.P.F. OUTPUT terminals for connections with the amplifier will improve sound quality of your speaker system.
The H.P.F. (High-Pass Filter) OUTPUT terminals of the subwoofer cut off frequencies below the selected frequency point from
the input signals, and output high frequencies only. By connecting this terminal with the MAIN IN terminals of the amplifier, the
main speakers reproduce high frequencies only.
This will make the whole sound quality clear by preventing sound muddying between the main speakers and the subwoofer.
* This connection can be made if your amplifier has PRE OUT and MAIN IN terminals or you are using separate amplifiers
(pre-amplifier and main amplifier).

Battery replacement
If you find that the remote control must be used closer to
the main unit, the batteries are weak. Replace both
batteries with new ones.
Notes
● Use only AA, R6, UM-3 batteries for replacement.
● Be sure the polarities are correct. (See the illustration
inside the battery compartment.)
● Remove the batteries if the remote control will not be
used for an extended period of time.
● If batteries leak, dispose of them immediately. Avoid
touching the leaked material or letting it come in contact
with clothing, etc. Clean the battery compartment
thoroughly before installing new batteries.
Notes
● There should be no large obstacles between the remote
control and the main unit.
● If the remote control sensor is directly illuminated by
strong lighting (especially an inverter type of fluorescent
lamp etc.), it might cause the remote control not to work
correctly. In this case, reposition the main unit to avoid
direct lighting.

system. When the subwoofer is connected to the
components for custom installation system, you can
operate the subwoofer with the system remote control.
C 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 on page 14. If you do not need
this function, leave this switch in the OFF position.
D GND terminal
Connecting this terminal to ground (GND) terminal of
the receiver/amplifier can reduce a humming noise.
(See page 10.)
E H.P.F. (High Pass Filter) OUTPUT switch
Selects the upper limit of the frequencies to be cut off
from the signals outputted at the H.P.F. OUTPUT
terminals. Use this switch only when the H.P.F.
OUTPUT terminals are used for connecting with the

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 by the automatic power-
switching function, 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.
* 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 STANDBY/ON button to
“ON”).
This function will not work if the subwoofer is turned
into the standby mode by using the STANDBY/ON
button. (The power indicator on the front panel goes
off.)

1 Set the volume level on the amplifier to
minimum, and turn on the amplifier and
other components.
2 Turn the VOLUME control to set the control
to minimum (0).
3 Make sure that the POWER switch on the
rear panel is set to the ON position, then
press the STANDBY/ON button to turn on
the subwoofer.
* The power indicator lights up in green.
4 Play a source containing low-frequency
components and adjust the amplifier’s
volume control to the desired listening level.
5 Turn the HIGH CUT control (or press the
HIGH CUT UP/DOWN buttons on the
remote control) to set the control to the
position where the desired response can be
obtained.
Normally, set the control to the main speaker’s rated
minimum reproducible frequency*.
* The main speaker’s rated minimum reproducible
frequency can be looked up in the speakers’ catalog
or owner’s manual.
6 Increase the volume gradually to adjust the
volume balance between the subwoofer and
the main speakers.
Normally, set the control to the level where you can
obtain a little more bass effect than when the subwoofer
is not used. If the desired response cannot be obtained,
adjust the HIGH CUT control and the VOLUME control
again.
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.
7 Press the PHASE button to select the
regular or reverse mode which gives you the
better bass sound.
Normally, select the reverse mode (so that the PHASE
indicator on the front panel lights up in green). If the
desired response cannot be obtained, select the regular
mode (so that the PHASE indicator lights up in red).
8 Select “MOVIE” or “MUSIC” according to the
played source.
MOVIE (when the MUSIC/MOVIE indicator on the front
panel lights up in green):
When a movie type source is played, the low-frequency
effects are enhanced to allow the listener enjoy more
powerful sound. (The sound will be thicker and deeper.)
MUSIC (when the MUSIC/MOVIE indicator on the front
panel lights up in red):
When an ordinary music source is played, the excessive
low-frequency components are cut off to make the
sound clearer. (The sound will be lighter and repro-
duces the melody line more clearly.)
• 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 to
others, you must make this adjustment again.
• For adjusting the VOLUME control, the HIGH
CUT control and the PHASE button, refer to
“Frequency characteristics” on page 17.

ADVANCED YAMAHA ACTIVE SERVO TECHNOLOGY
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.
