GLOSSARY
• 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.
I-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.l-channel
configuration can be freely selected for your enjoyment.
• 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 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" ryfers to 24-bit word length. DTS 96/
24 offers sound quality transparent
to
the original 96/24
master, and 96/24
5.
I-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.
I-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.
• ITU-R
ITU-R
is
the radio communication sector
of
the lTV
(International Telecommunication Union). ITU-R
recommends a standard speaker placement which is used
in many critical listening rooms, especially for mastering
purposes.
• LFE
0.1
channel
This channel reproduces low-frequency signals. The
frequency range of this channel
is
from 20 Hz to 120 Hz.
This channel
is
counted
as
0.1
because it only enforces a
low-frequency range compared to the full-range
reproduced by the other 5/6 channels in Dolby Digital or
DTS
5.116.
I-channel systems.
• 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. There
are two modes available: "Music mode" for music sources
and "Cinema mode" for movie sources.
