Dts Digital Surround - Yamaha DSP-A1 Owner's Manual

Dolby Digital (AC-3) forms 5.1 channels as mentioned on the
previous page, and moreover, it can also form fewer channels,
for example 2 channel stereo and monaural. You may be able
to find some 2 channel stereo and/or monaural sources
encoded with the Dolby Digital (AC-3) in a market.
If a 2 channel stereo source encoded with the Dolby Digital
(AC-3) is played back as the input source and the DSP
program No. 10, 11 or 12 is used at the same time, the source
is first decoded with the Dolby Digital (AC-3) decoder into 2
channels, and then decoded with the Dolby Pro Logic decoder.
In such a case, only the decoding of Dolby Pro Logic is shown
on the display panel of this unit.

DTS Digital Surround

The DTS (Digital Theater Systems) system was developed to
replace analog soundtracks of movies with six discrete
channels of digital soundtracks, and now, it is 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.
The DTS technology, through intense research and
development, made it possible to deliver a similar
encode/decode discrete technology to home audio surround-
sound entertainment.
The DTS Digital Surround is an encode/decode system which
delivers six channels of master-quality, 20-bit audio; technically
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
The DTS Digital Surround algorithm is designed to encode the
six channels of 20-bit audio onto any laserdisc or compact disc
(or DVD in the near future) with considerably less data-
compression.

Laserdisc and DVD are home audio formats that could benefit
from Dolby Digital (AC-3). In the near future, Dolby Digital (AC-
3) will also be applied to DBS, CATV and HDTV. The ongoing
release of Dolby Stereo Digital theatrical films now underway
will provide an immediate source of Dolby Digital (AC-3)
encoded video software.

By using the DTS decoder built into this unit, you can
experience the dramatic realism and impact of the DTS
installed theater's high quality sound in your own home.
Laserdisc and compact disc (and DVD in the near future) are
home audio format within which DTS can represent its high
quality multi-channel audio. (In addition to movies on
laserdiscs, many exciting new multi-channel music recordings
will also become available in the form of DTS-encoded
compact discs.)
