Dolby Digital
Dolby Digital is a digital surround sound system that gives
you completely independent multi-channel audio. With 3
front channels (front L/R and center), 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
speakers, 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 unprecedented
excitement and realism. With this unit, any sound
environment from monaural up to a 5.1-channel
configuration can be freely selected for your enjoyment.
Dolby Digital EX
Dolby Digital EX creates 6 full-bandwidth output
channels from 5.1-channel sources. This is done using a
matrix decoder that derives 3 surround channels from the
2 in the original recording. 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 Pro Logic II
Dolby Pro Logic II is an improved technique used to
decode vast numbers of existing Dolby Surround sources.
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. There are three modes available: “Music
mode” for music sources, “Movie mode” for movie
sources and “Game mode” for game sources.
Dolby Pro Logic IIx
Dolby Pro Logic IIx is a new technology enabling discrete
multi-channel 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.
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 Theater Systems)
Digital Surround
DTS digital surround was developed to replace the analog
soundtracks of movies with a 6.1-channel digital sound
track, and is now rapidly gaining popularity in movie
theaters around the world. Digital Theater Systems 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 6.1-channel sound (technically,
front left and right, center, surround left and right, and
LFE 0.1 (subwoofer) channels for a total of 5.1 channels).
This unit incorporates a DTS-ES decoder that enables 6.1-
channel reproduction by adding the surround back channel
to the existing 5.1-channel format.
ITU-R
ITU-R is the radio communication sector of the ITU
(International Telecommunication Union). ITU-R
recommends a standard speaker placement which is used
in many critical listening rooms, especially for mastering
purposes.
