to use. Incorporated state-of-art technology such as Dolby Digital and DTS can bring the same audio experience to your home
as they have brought to feature films in quality theaters around the world. Take some time now to read more about these
features and enjoy the new experiences this system brings to your home theater.

Dolby Surround

Dolby Surround uses four discrete channels and five
speakers to reproduce realistic and dynamic sound effects:
two main channels (left and right), a center channel for
dialog, and a rear channel for special sound effects. The
rear channel reproduces sound within a narrow frequency
range.
Most video tapes and laser discs include Dolby Surround
encoding, as do many TV and cable broadcasts. The Dolby
Pro Logic decoder built into this unit employs a digital signal
processing system that stabilizes each channel for even
more accurate sound positioning than is available with
standard analog processors.

Dolby Digital
Dolby Digital is a digital surround sound system that
provides completely independent multi-channel audio to
you. Dolby Digital provides five full-range channels in what
is sometimes referred to as a "3/2" configuration: three front
channels (left, center and right), and two surround channels.
A sixth bass-only effect channel is also provided for output
of LFE (low frequency effect), or low bass effects that are
independent of other channels. (This is called the "LFE
channel".) This channel is counted as 0.1, thus giving rise to
the term 5.1 channels in total.
The wide dynamic range of sound reproduced by the five
full-range channels and precise sound orientation by digital
sound processing provides listeners with excitement and
realism that have never been experienced before.
DTS (Digital Theater System) Digital
**
Surround
DTS was developed to replace the analog soundtracks of
movies with six discrete channels of digital soundtracks,
and it is now installed in many theaters around the world.
The DTS digital playback system changed the way we
experienced movies in theaters with six discrete channels of
superb digital audio.
DTS technology, through intense research and development
has made it possible to deliver similar encode/decode
discrete technology to home audio surround-sound
entertainment.
DTS Digital Surround is an encode/decode system which
delivers six channels of master-quality, 20-bit audio;
technically, it is 5.1 channels, which means 5 full-range (left,
center, right and two surround) channels, plus a subwoofer
(LFE) channel (as "0.1"). It is compatible with the 5.1
speaker configurations that are currently available for home
theater systems.
Notes
● When playing an ordinary CD on this system following
playback of a CD or an LD encoded with DTS, some
operations, such as resetting input modes, may be required.
● Even if connected to this system with a digital connection,
some CD, LD, and DVD players may make this system fail to
decode DTS or produce noise. This is because certain digital
output data processing by such a player results in DTS-
encoded data errors that cause playback failure although the
same data processing may cause only a slight change in
volume or in frequency response in normal digital sound.
● When an error occurs in the player's digital output data during
playback of an LD or CD encoded with DTS, playback may
be disrupted. If this occurs, stop playback and repower the
player.
● When digital sound signals from the computer are played,
errors in WAVE signals, etc. may occur resulting in noise or a
playback failure.
