I Dolby Surround
Dolby Surround uses a four analog channel recording
system to reproduce realistic and dynamic sound effects:
two left and right main channels (stereo), a center channel
for dialog (monaural), and a rear channel for special
sound effects (monaural). The rear 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.
I Dolby Digital
Dolby Digital is a digital surround sound system that
gives you completely independent multi-channel audio.
With three front channels (left, center and right), and two
rear stereo channels, Dolby Digital provides five 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).
Using two-channel stereo for the rear 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 five 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 freely selected for
your enjoyment.
I Dolby Digital Surround EX
This unit is equipped with the Dolby Digital decoder that
can reproduce 5.1-channel sources adding a rear center
channel. (The sound to be output from a rear center
speaker is created by mixing the content of rear L/R
channels.) This decoder is the most suitable to reproduce
the soundtrack for the movies recorded by Dolby Digital
Surround EX. You can enjoy dynamic and realistic sounds
by adding another channel.

GLOSSARY

I Dolby Pro Logic
Dolby Pro Logic
vast numbers of existing Dolby Surround programs. This
new technology enables a discrete 5-channel playback
with two left and right main channels, a center channel,
and two left and right rear channels compared with one
limited rear channel for the conventional Pro Logic
technology. Also the music mode is available for 2-
channel sources in addition to the movie mode.
I DTS (Digital Theater Systems)
Digital Surround
DTS digital surround was developed to replace the analog
soundtracks of movies with a six-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 is practically distortion-free, clear 6-channel
sound (technically, a left, right and center channels, two
rear channels, plus an LFE 0.1 channel as a subwoofer,
for a total of 5.1 channels).
I DTS ES (Extended Surround)
This unit is equipped with the DTS ES decoder that can
reproduce 5.1-channel sources adding a rear center
channel. The DTS ES decoder on this unit is compatible
with the two types of format: Discrete 6.1 and Matrix 6.1.
The DTS ES Discrete decoder enables the 6.1-channel
playback by adding a rear center channel recorded
independently from the 5.1 channels. The DTS ES Matrix
decoder enables the 6.1-channel playback by adding a
rear center created from the rear L/R channels. This
decoder is the most suitable to reproduce the music or the
soundtrack of the movies recorded by DTS ES.
I 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.
I DTS 96/24
DTS 96/24 achieves the high quality playback with all 5.1
channels at the sampling frequency 96 kHz / 24 bit by
using the data for extension of a DTS signal, that is
recorded on the DTS 96/24 software.
