INFORMATION
■ 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.
■ DSD
Direct Stream Digital (DSD) technology stores audio
signals on digital storage media, such as Super Audio
CDs. Using DSD, signals are stored as single bit values at
a high-frequency sampling rate of 2.8224 MHz, while
noise shaping and oversampling are used to reduce
distortion, a common occurrence with very high
quantization of audio signals. Due to the high sampling
rate, better audio quality can be achieved than that offered
by the PCM format used for normal audio CDs.
■ 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.
■ HDMI
HDMI (High-Definition Multimedia Interface) is the first
industry-supported, uncompressed, all-digital audio/video
interface. Providing an interface between any source (such
as a set-top box or AV receiver) and an audio/video
monitor (such as a digital television), HDMI supports
standard, enhanced or high-definition video as well as
multi-channel digital audio using a single cable. HDMI
transmits all ATSC HDTV standards and supports 8-
channel digital audio, with bandwidth to spare to
accommodate future enhancements and requirements.
When used in combination with HDCP (High-bandwidth
Digital Content Protection), HDMI provides a secure
audio/video interface that meets the security requirements
of content providers and system operators. For further
information on HDMI, visit the HDMI website at
“http://www.hdmi.org/”.
■ 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 5.1/6.1-channel systems.
■ MP3
One of the audio compression methods used by MPEG. It
employs the irreversible compression method, which
achieves a high compression rate by thinning out the data
of hardly audible part to the human ears. It is said to be
capable of compressing the data quantity by about 1/11
(128 kbps) while maintaining a similar audio quality to
music CD.
■ 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.
■ Neural Surround
Neural Surround
™
represents the latest advancement in
surround technology and has been adopted by XM
Satellite Radio for digital radio broadcast of surround
recordings and live events in surround sound. Neural
Surround
™
employs psychoacoustic frequency domain
processing which allows delivery of a more detailed sound
stage with superior channel separation and localization of
audio elements. System playback is scalable from 5.1 to
7.1 multi-channel surround playback.
