•

This subwoofer system employs YAMAHA Active Servo

Technology which YAMAHA developed for reproducing

higher quality super-bass sound. (Refer to page 14 for

details on Active Servo Technology.)

This unit does not only enhance bass frequency response

of sound output in your audio system, but, by reproducing

the bass frequencies, the subwoofer permits your existing

amplifier and speakers to operate under less strenuous

conditions, improving overall system performance.

•

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.

•

For the effective use of this unit, this unit’s super-bass

sound must be matched to the sounds on your main

speakers. Therefore, this unit employs the continuously

variable high frequency cut-off point (HIGH-CUT) control.

Moreover, the PHASE switch allows you to select better

sound quality according to the listening condition.

•

As a utility function for using two subwoofers, this unit has

two types of signal code for remote control. By selecting a

different code for each subwoofer, you can operate two

subwoofers individually with one remote control transmitter.

If using one subwoofer system, it is recommended to place it

on the outside of either the right or the left main speaker. (See

fig. .) If using two systems, it is recommended to place them

on the outside of each main speaker. (See fig. .) The

placement shown in fig. 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 will collide. To prevent this, face the

subwoofer system obliquely to the wall as shown in fig. or

One subwoofer system will have a good effect on your audio

system, however, the use of two subwoofer systems is

recommended to obtain more presence.

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 the “standing waves” occur 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.

If your amplifier has two sets of speaker terminals

For connections, use speaker wires of the proper gauge, cut

as short as possible. If the connections are faulty, no sound

will be heard from the speakers. Make sure that the polarity of

the speaker wires is correct, that is, + and – markings are

observed. If these wires are reversed, the sound will be

unnatural and will lack bass. Do not let the bare speaker

wires touch each other and do not let them touch the

metal parts of this unit as this could damage this unit,

your amplifier and/or speakers.

How to Connect:

Red: positive (+)

ACTIVE SERVO TECHNOLOGY

The theory of Active Servo Technology is 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 Active Servo Technology.
