radiate from the rear panel. Therefore, place the unit apart

from the walls, allowing enough space above, behind and

on the both sides of the unit to prevent fire and damage.

Also, do not position with the rear panel facing down on

the floor or other surface.

Be sure to allow a space of at least 20 cm above, behind

and on the both sides of the unit.

10.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.

11. Vibration generated by super-bass frequencies may cause

images on a TV to be distorted. In such a case, move this

unit away from the TV set.

12.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.

13.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

FEATURES

• 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 Technol-

ogy.) This super-bass sound adds a more realistic, theater-

in-the-home effect to your stereo system.

• This unit can be added easily to your existing audio system

by connecting to either the speaker terminals or the line

output (pin jack) terminals of the amplifier.

PLACEMENT

One subwoofer will have a good effect on your audio system,

however, the use of two subwoofers is recommended to obtain

more presence.

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. To prevent this, face the subwoofer system

obliquely to the wall as in fig. Å or ı.

Note

There may be a case that you cannot obtain enough super-

bass 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 canceled.

In such a case, face the unit obliquely to the wall. It also may

be necessary to break up the parallel surfaces by placing

bookshelves etc. along the walls.

CONTROLS AND THEIR FUNCTIONS

Automatic Standby function

When you play a source, the power of 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 low frequency input signal is

cut off for several minutes.

This function will operate by sensing a certain level of low

frequency input signal. Its sensitivity is high in the HIGH

position and low in the LOW position of the AUTO STANDBY

switch. In the HIGH position, the power will turn on even with

a low level of input signal, but on the other hand this unit may

not turn into the standby mode when there is an input signal

even if its level is extremely low.

* There may be a case that the power turns on unexpectedly

by sensing noise from other appliances. If it occurs, set the

AUTO STANDBY switch to the OFF or LOW 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

sources.

This function is available only when the power of this

unit is on (by setting the STANDBY/ON button Ÿ to ON).

Power indicator

Lights up while this unit is ON.

* If the AUTO STANDBY switch on the rear panel is set

to the LOW or HIGH position, this indicator is illumi-

nated dimly when no signal is input to this unit.

STANDBY/ON button

Each press of this button turns the unit on and off (on

standby). A small amount of power is always consumed

even while this unit is on standby.

HIGH CUT control

Adjusts the high frequency cut off point.

Frequencies higher than the frequency selected with this

control are all cut off (and not output).

⁄

VOLUME control

Adjusts the volume level.

Main POWER switch

Normally, leave this switch to the ON position. When you

will not use this unit for a long period, set this switch to the

OFF position.

AUTO STANDBY switch

Processing

Amplifier

Signals

Signals of low amplitude

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 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.

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

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 maximum sound pressure

compared with the conventional Yamaha Active Servo

Technology, resulting in more natural and energetic bass

reproduction.
