Glossary for Audio Stream & Surround Mode
Glossary for Audio Stream
The Dolby Digital surround format lets you enjoy up to 5.1
channels of digital surround sound from a Dolby Digital pro-
gram source. If you play DVDs with "
even better sound quality, greater spatial accuracy, and
improved dynamic range.
Use this mode when playing movie with Dolby Digital 2 chan-
nel, which carries the " " mark. This mode realistically
simulates a movie theater or live concert house using DOLBY
PRO LOGIC SURROUND technology. The front/back/left/right
sound movement, as well as fixed positions in the sound
image is much clearer and more dynamic than before.
(II)
Dolby Pro Logic II creates five full-bandwidth output channels
from two-channel sources. This is done using an advanced,
high-purity matrix surround decoder that extracts the spatial
properties of the original recording without adding any new
sounds or tonal colorations.
MOVIE mode:
The Movie mode is for use with stereo television shows and all
programs encoded in Dolby Surround. The result is enhanced
sound field directionality that approaches the quality of discrete
5.1-channel sound.
MUSIC mode:
The Music mode is for use with any stereo music recordings.
MATRIX mode:
The Matrix mode is the same as the Music mode except that the
directional enhancement logic is turned off. It may be used to
enhance mono signals by making them seem "larger." The Matrix
mode may also find use in auto systems, where the fluctuations
from poor FM stereo reception can otherwise cause disturbing
surround signals from a logic decoder. The ultimate "cure" for
poor FM stereo reception may be simply to switch the audio to
mono.
3D SURROUND
This unit can produce a 3D Surround effect, using 3D Surround
Sound technology, which simulates multi-channel audio play-
back from two conventional stereo speakers instead of the five
or more speakers normally required to listen to multi-channel
audio from a home theater. This feature works with DVD discs
encoded with Dolby Pro Logic and Dolby Digital audio tracks.
BYPASS
Software with multi-channel surround audio signals is played back
according to its original recording specifications.
Surround Mode
You can enjoy surround sound simply by selecting one
of the pre-programmed sound fields according to the
program you want to listen to.
