PLACEMENT
: main speaker)
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 superbass sounds from the subwoofer 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.
Use the nonskid pads
Put the provided nonskid pads at the four corners on the
bottom of the subwoofer to prevent the subwoofer from
moving by vibrations etc.

Can be used for connecting to the main speakers.
Signals from the INPUT1 terminals (6) are sent to
these terminals.
VOLUME control
Adjusts the volume level. Turn the control clockwise to
increase the volume, and counterclockwise to
decrease the volume.
HIGH CUT (HIGH/LOW) switch
Selects the high frequency cut off point.
Normally, it is set to LOW, however, you may set to
HIGH if necessary. Refer to page 10.
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 powerswitching 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 will operate 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 subwoofer 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. The tone
balance may change, however, depending on
the room size, the distance from the subwoofer
to the main speakers, and so on. If necessary,
switch it to the HIGH position.

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
this unit is not used. If the desired response
cannot be obtained, adjust the HIGH CUT
switch and the VOLUME control again.
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 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 and the HIGH CUT
switch, refer to “Frequency characteristics” on page 11.

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, lowfrequency 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.
