dts DIGITAL SURROUND
#1: What is DTS Digital Surround?
FINEST 5.1 SURROUND SOUND TECHNOLOGY ON THE MARKET TODAY!
amazing new technology for surround-sound entertainment, DTS Digital
Surround is an encode/decode system that delivers six channels (5.1)
of master- quality, 20-bit audio. In the encoding process, the DTS algorithm
encrypts 6 channels of 20-bit digital audio information in the space
previously allotted for only 2 channels of 16-bit linear PCM. Then during
playback, the DTS decoder reconstructs the original 6 channels of 20-bit
digital audio. Each of these 6 channels is audibly superior to the 16-bit
linear PCM audio found on conventional compact discs.
#2: How does this format compare to Dolby Digital (AC-3)?
AUDIO QUALITY FOR BOTH MOVIES AND MUSIC.
DTS master-quality mode, for laserdiscs, compact discs, and DVDs, use
less than one-fourth the data reduction of Dolby Digital (AC-3), resulting
in audibly superior performance. The DTS commitment is to deliver an
uncompromised reproduction of the original multi-track masters. For
laserdiscs, however, this approach allocates all of the available digital-audio
data space to the new six channels of audio, while Dolby Digital uses
high data-reduction to fit their digital data onto an analog stereo
track, leaving the stereo PCM tracks in-tact.
#3: What equipment do I need to playback in DTS?
CHANNELS OF ELECTRONICS AND SPEAKERS, WITH A DTS DECODER.
discrete 5.1 audio system is required to experience this state-of-the-art
technology. That means a system with six separate channels of electronics
and speakers; for left, center, right, left surround, right surround
and subwoofer (the .1 channel). The electronics can consist of any 5.1
surround processor with a built-in DTS decoding circuit or add-on DTS
decoder, plus six channels of amplification (or five channels plus a
powered subwoofer). Since the introduction of an advanced Motorola chip
that can be easily integrated into any multi-channel product, all new
models (including all-in-one receivers) can now offer both DTS and Dolby
A popular analogy draws comparisons to AM and FM radio transmissions.
You cannot receive AM signals on a FM radio and vice-versa. However,
for maximum choices in entertainment, your radio can be equipped with
both technologies, so that you can select one or the other at the flip
of a switch. And while there have always been practical uses for the
low-fidelity broadcasts on AM radio, the success of FM-stereo is a strong
example of the demand for higher-quality sound.
MOVIES ON LASERDISC
#1: What is unique about DTS Digital Surround laserdiscs?
BEST SOUNDING MULTI-CHANNEL AUDIO EVER OFFERED.
Digital Surround laserdiscs have been encoded with six channels of master-quality
audio. For the first time, you can experience the multi-channel soundtracks
that Digital Theater Systems (DTS) provides to more than 11,000 movie
theaters around the world. And the only requirements ar an existing
laserdisc player with a digital output interface and a DTS decoder.
#2: How do DTS-encoded laserdiscs compare to Dolby Digital (AC-3) titles?
SOUNDTRACKS, WITH EXISTING PLAYERS.
previously discussed, all DTS soundtracks are encoded with considerably
less data reduction than Dolby Digital, to deliver 6 channels of sonic
perfection. In addition, Dolby has chosen a stereo-compatible approach,
by RF-modulating the six channels of audio onto a single analog track;
thereby preserving the original stereo digital tracks. However, this
approach requires the purchase of a new laserdisc player with a special

LASERDISCS SOUND GREAT, DTS DVDs SOUND GREAT.
manufacturers are gearing up product to demonstrate the many benefits
of the new DVD format. And its reasonable to predict that this new technology
may someday become the dominant format for all home entertainment applications.
However, the number of years that it will take for this transition to
occur will be dependent upon the depth of software that becomes available.
DTS is also one of the multi-channel standards for DVD and is committed
to support both laserdiscs and DVDs. First, by ensuring the availability
of a wide variety of DTS-encoded laserdiscs with state-of-the-art soundtracks,
for laserdisc fans. And also, by delivering a wide variety of DVD software
titles that truly represent the highest quality sound and picture that
this new format is capable of delivering.
MUSIC ON COMPACT DISC
#1: What is a DTS Digital Surround music disc?
MUSIC MIXES WITH MASTER QUALITY SOUND.
Theater Systems (DTS) is already recognized around the world for providing
the finest surround sound digital audio tracks ever developed for motion
pictures. Now DTS brings Digital Surround technology to music recordings,
creating the opportunity to experience a truly state-of-the-art multi-channel
mix of any multi-channel master. The result is a new level of sonic
realism that dramatically transcends all previous stereo versions, changing
forever the way we can experience recorded music.
#2: How do these multi-channel mixes compare to the quad titles of the
DIGITAL TECHNOLOGY CAN FAR SURPASS 4-CHANNEL ANALOG.
in the seventies, there were several attempts to bring four-channel
sound into the home. The idea of multi-channel in the home was a good
one, but the needle-in-groove technology of the time limited the quality
and separation of the music to such an extent that quad eventually faded
away. Now, DTS makes it possible to deliver what the quad systems of
the seventies only hinted at. Multi-channel mixes can now be reproduced
in the home exactly as they sound in the studio control room, with six
completely discrete channels in 20-bit resolution.
#3: What kind of equipment is needed to experience DTS-encoded music
DISCRETE 5.1 PLAYBACK SYSTEM WITH A DIGITAL OUT CD PLAYER
compact discs play on any 5.1 discrete surround system that utilizes
a DTS decoder and a compact disc player (or laserdisc combi-player)
with a digital output. And all DTS-encoded movies and music recordings
are mixed and mastered compatibly with the 5.1 speaker configurations
that are designed for home theater audio systems. However, it is already
anticipated that each title will vary in terms of how each artist/engineer/producer
chooses to mix their multi-channel master, and what musical information
is allocated into each of the five full-range channels and the L.F.E.
(.1) sub-woofer track. For optimum playback of all future recordings,
it is highly recommended that full-range, equally-matched loudspeakers
are utilized for all five of the main channels (including the surrounds).
