Introduction Features

• This subwoofer system employs Advanced
Yamaha Active Servo Technology II which
Yamaha has developed for reproducting higher
quality super-bass sound. (Refer to page 6 for
details on Advanced Yamaha Active Servo
Technology II) This super bass sound adds a
more realistic, theater-in-the-home effect to

( U.S and CANADA model only )

It is recommended to place the subwoofer on the
outside of either the right or the left front 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 may cancel out each other. To
prevent this from happening, face the subwoofer
system at an angle as shown in fig. .

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.

Advanced Yamaha Active Servo Technology II

In 1998, Yamaha brought to the marketplace
speaker systems utilizing YST (

Servo Technology

) to give powerful, high quality

Yamaha Active

bass reproduction. This technique uses a direct
connection between the amplifier and speaker,
allowing accurate signal transmission and precise
speaker control.

As this technology uses speaker units controlled by
the negative impedance drive of the amplifier and
resonance generated between the speaker cabinet
volume and port, it creates more resonant energy
(the “air woofer” concept) than the standard bass

reflex method. This allows for bass reproduction
from much smaller cabinets than was previously
possible.
Yamaha’s newly developed Advanced YST II adds
many refinements to Yamaha Active Servo
Technology, allowing better control of the forces
driving the amplifier and speaker. From the
amplifier’s point of view, the speaker impedance
changes depending on the sound frequency.
Yamaha developed a new circuit design combining
negative-impedance and constant-current drives,
which provides a more stable performance and
clear bass reproduction without any murkiness.
