Dolby Digital is a digital surround sound system that gives 
you completely independent multi-channel audio. With 3 
front channels (left, center, and right), and 2 surround 
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 surround 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 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 freely selected for 
your enjoyment.

Dolby Pro Logic II is an improved technique used to 
decode vast numbers of existing Dolby Surround 
software. This new technology enables a discrete 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 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, a left, right and center channels, 2 surround 
channels, plus an LFE 0.1 channel as a subwoofer, for a 
total of 5.1-channels). The unit incorporates a DTS-ES 
decoder that enables 6.1- channel reproduction by adding 
the surround back channel to existing 5.1-channel format.

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.
