• Dolby Digital
Dolby Digital is a digital sun'ound sound system that gives
you completely independent multi-channel audio. With 3
front channels (left, center, and right), and 2 sun'ound
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 sun'ound speakers, more
accurate moving sound effects and surround sound
environment are possible than with Dolby Surround. The
wide dynamic range (from maximum to mininmm
volume) reproduced by the 5 full-range channels and the
precise sound orientation generated using digital sound
processing provide listeners with previously unheard of
excitement and realism.
With this unit, any sound environment from monaural up
to a 5.1-channel configuration can be fi'eely selected for
your el_ioyment.
• Dolby Pro Logic II
Dolby Pro Logic II is an improved technique used to
decode vast numbers of existing Dolby Sun'ound
software. This new technology enables a discrete 5-
channel playback with 2 front left and right channels, 1
center channel, and 2 sun'ound left and right channels
(instead of only 1 sun'ound channel for conventional Pro
Logic technology). Music and Game modes are also
available for 2-channel sources in addition to the Movie
mode.
• 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), acenter channel for dialog
(monanral), and a surround channel for special sound
effects (monaural). The sun'ound channel reproduces
sound within a narrow fi'equency range.
Dolby Sun'ound 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 9624 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 nmsic programs and motion picture
soundtracks on DVD-video.
• DTS (Digital Theater Systems)
Digital Surround
DTS digital sun'ound 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. 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-channel sound
(technically, a left, right and center channels, 2 sun'ound
channels, plus an LFE 0.1 channel as a subwoofer, for a
total of 5.i-channels). The unit incorporates a DTS-ES
decoder that enables 6.1- channel reproduction by adding
the sun'ound back channel to existing 5.1 -channel format.
• Neo:6
Neo:6 decodes the conventional 2-chmmel 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.
