Dolby Digital is a digital surround sound system that gives 
you completely independent multi-channel audio. It 
provides 5 full-range audio channels; 3 front channels 
(left, center, and right), and 2 surround stereo channels. 
An additional channel especially for bass effects, called 
LFE (low frequency effect) is also provided giving the 
system a total of 5.1-channels (LFE is counted as a 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 (maximum to 
minimum volume) reproduced by the 5 full-range 
channels and the precise sound orientation generated 
using digital sound processing provide listeners with a 
previously unheard of excitement and realism.

■

Dolby Digital EX creates 6 full-bandwidth output 
channels from 5.1-channel sources. This is done by using 
a matrix decoder that derives 3 surround channels from 
the 2 in the original recording. For best results, Dolby 
Digital EX should be used with movie sound tracks 
recorded with Dolby Digital Surround EX. With this 
additional channel, you can experience more dynamic and 
realistic moving sound especially with scenes that have 
“flyover” and “fly-around” effects.

■

Dolby Pro Logic II is an improved technique used to 
decode vast numbers of existing Dolby Surround 
software. This new technology enables a 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). Music and Game modes are also available 
for 2-channel sources in addition to the Movie mode.

■

Dolby Pro Logic IIx is a new technology enabling 6.1 or 
7.1 multi-channel playback from 2-channel or multi-
channel sources. There is a Music mode for music, a 
Movie mode for movies and a Game mode for games.

■

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 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 surround 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, left, right and center channels, 2 surround 
channels, plus an LFE 0.1 channel as a subwoofer, for a 
total of 5.1-channels). This unit incorporates a DTS-ES 
decoder that enables 6.1- channel reproduction by adding 
a surround back channel to the existing 5.1-channel 
format.

■

Neo:6 decodes conventional 2-channel sources for 6 
channel playback by. It enables playback with the full-
range channels with higher separation comparable to 
digital discrete signal playback. Two modes are available; 
“Music mode” for playing music sources and “Cinema 
mode” for movies.
