OUTLINE OF THIS UNIT
Dolby Digital and DTS
This unit features a built-in Dolby Digital decoder and a DTS decoder for reproducing surround sounds of sources encoded
with Dolby Digital or DTS. With such state-of-the-art technologies, this unit 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.
Ⅵ
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 offers 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.
Ⅵ
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 surround channel for special sound effects.
The surround 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.
Ⅵ
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.
