GLOSSARY
Audio formats
Dolby Digital
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
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.

GLOSSARY
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
(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 (Digital Theater Systems)
Digital Surround
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).
