■ Dolby Digital
Dolby Digital is a digital surround sound system that gives you
completely independent multi-channel audio. With 3 front channels
(left, center, and right) and 2 surround stereo channels, Dolby Digital
provides 5 full-range audio channels. With an additional channel
especially for bass effects, called LFE (low-frequency effect), the
system has a total of 5.1-channels (LFE is counted as 0.1-channel).
By using 2-channel stereo for the surround channels, more accurate
moving sound effects and surround sound environment are possible
than with Dolby Surround. The wide dynamic range (from maximum
to minimum volume) reproduced by the 5 full-range channels and the
precise sound orientation generated using digital sound processing
provide listeners with excitement and realism previously unheard of.
With this unit, any sound environment from monaural up to a 5.1-
channel configuration can be freely selected for your enjoyment.
■ Dolby Digital Surround EX
Dolby Digital EX creates 6 full-bandwidth output channels from 5.1-
channel sources.
For the best results, Dolby Digital EX should be used with movie
sound tracks recorded with Dolby Digital Surround EX. With this
additional channel, you can experience more dynamic and realistic
moving sound especially with scenes with "fly-over" and "fly-
around" effects.
■ Dolby Digital Plus
Dolby Digital Plus is an advanced audio technology developed for
high-definition programming and media including HD broadcasts,
and Blu-ray Disc. Selected as an optional audio standard for Blu-ray
Disc, this technology delivers multichannel sound with discrete
channel output. Supporting bitrates up to 6.0 Mbps, Dolby Digital
Plus can carry up to 7.1 discreet audio channels simultaneously.
Supported by HDMI version 1.3 and designed for the optical disc
players and AV receivers/amplifiers of the future, Dolby Digital Plus
also remains fully compatible with the existing multichannel audio
systems that incorporate Dolby Digital.
■ Dolby Pro Logic II
Dolby Pro Logic II is an improved technique used to decode vast
numbers of existing Dolby Surround software. This new technology
enables a discrete 5-channel playback with 2 front left and right
channels, 1 center channel, and 2 surround left and right channels
(instead of only 1 surround channel for conventional Pro Logic
technology). Music and Game modes are also available for 2-channel
sources in addition to the Movie mode.
■ Dolby Pro Logic IIx
Dolby Pro Logic IIx is a new technology enabling discrete
multichannel playback from 2-channel or multi-channel sources.
There are three modes available: "Music mode" for music sources,
"Movie mode" for movie sources (for 2-channel sources only) and
"Game mode" for game sources.
■ Dolby Surround
Dolby Surround uses a 4-channel analog recording system to
reproduce realistic and dynamic sound effects: 2 front left and right
channels (stereo), a center channel for dialog (monaural), and a
surround channel for special sound effects (monaural). The surround
channel reproduces sound within a narrow frequency range.
Dolby Surround is widely used with nearly all video tapes and laser
discs, and in many TV and cable broadcasts as well. The Dolby Pro
Logic decoder built into this unit employs a digital signal processing
system that automatically stabilizes the volume on each channel to
enhance moving sound effects and directionality.

■ Dolby TrueHD
Dolby TrueHD is an advanced lossless audio technology developed
for high-definition disc-based media including Blu-ray Disc. Selected
as an optional audio standard for Blu-ray Disc, this technology
delivers sound that is bit-for-bit identical to the studio master,
offering a high-definition home theater experience.
Supporting bitrates up to 18.0 Mbps, Dolby TrueHD can carry up to 8
discrete channels of 24-bit/96 kHz audio simultaneously.
Dolby TrueHD also remains fully compatible with the existing
multichannel audio systems and retains the metadata capability of
Dolby Digital, allowing dialog normalization and dynamic range
control.
■ DTS 96/24
DTS 96/24 offers an unprecedented level of audio quality for multi-
channel sound on DVD video, and is fully backward-compatible with
all DTS decoders. "96" refers to a 96 kHz sampling rate compared to
the typical 48 kHz sampling rate. "24" refers to 24-bit word length.
DTS 96/24 offers sound quality transparent to the original 96/24
master, and 96/24 5.1-channel sound with full-quality full-motion
video for music programs and motion picture soundtracks on DVD
video.
■ DTS Digital Surround
DTS digital surround was developed to replace the analog
soundtracks of movies with a 6-channel digital sound track, and is
now rapidly gaining popularity in movie theaters around the world.
DTS, Inc. has developed a home theater system so that you can enjoy
the depth of sound and natural spatial representation of DTS digital
surround in your home. This system produces practically distortion-
free 6-channel sound (technically, left, right, and center channels, 2
surround channels, plus an LFE 0.1-channel as a subwoofer, for a
total of 5.1 channels). The unit incorporates a DTS-ES decoder that
enables 6.1-channel reproduction by adding the surround back
channel to existing 5.1-channel format.
■ DTS Neo:6
Neo:6 decodes the conventional 2-channel sources for 6-channel
playback by the specific decoder. It enables playback with the full-
range channels with higher separation just like digital discrete signal
playback. Two modes are available: Music mode for playing music
sources and Cinema mode for movies.
■ DTS-HD High Resolution Audio
DTS-HD High Resolution Audio is a high resolution audio
technology developed for high-definition disc-based media including
Blu-ray Disc. Selected as an optional audio standard for Blu-ray Disc,
this technology delivers sound that is virtually indistinguishable from
the original, offering a high-definition home theater experience.
Supporting bitrates up to 6.0 Mbps for Blu-ray Disc, DTS-HD High
Resolution Audio can carry up to 7.1 discrete channels of 24-bit/96
kHz audio simultaneously.
DTS-HD High Resolution Audio also remains fully compatible with
the existing multichannel audio systems that incorporate DTS Digital
Surround.
■ DTS-HD Master Audio
DTS-HD Master Audio is an advanced lossless audio technology
developed for high-definition disc-based media including Blu-ray
Disc. Selected as an optional audio standard for Blu-ray Disc, this
technology delivers sound that is bit-for-bit identical to the studio
master, offering a high-definition home theater experience.
Supporting bitrates up to 24.5 Mbps for Blu-ray Disc, DTS-HD
Master Audio can carry up to 7.1 discrete channels of 24-bit/96 kHz
audio simultaneously. Supported by HDMI version 1.3 and designed
