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),
a center 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 (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

a left, right and center channels,
2 sun'ound

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.

sources and "Cinema mode" for movies.
