How Do I Adjust the Surround?
DTS-ES Matrix 6.1 features matrix encoding of surround back (SB)
signals in the SL/SR signals and decoding of the matrix into the SL,
SR and SB signals during playback.
•MPEG: MPEG, which stands for “Moving Pictures Experts Group”, is
an international standard of digital video and audio compression and
decompression in media. It is the most efficient encoding method
for compressed multi-channel audio which provides the highest sound
quality to deliver the best movie theater sound into the home.
•Dolby Pro Logic/Dolby Pro Logic II: Dolby Pro Logic reproduces a
surround sound like in a movie theater from Dolby Surround-encoded
program source (videotape or LaserDisc software carrying the Dolby
Surround logo), and features excellent sound movement on the front
and a surrounding atmosphere of movie theaters. Meanwhile, Dolby
Pro Logic II decodes a signal encoded in 2 channels into 4-channel
signals composed of the left/right front signals, center signal and
surround signal.
Dolby Pro Logic II is an advanced version of the decoding technology
used with Dolby Pro Logic. It inputs 2-channel signals from a Dolby
Surround-encoded source and reproduces 5.1-channel signals in
which the surround channel is divided into independent channels
for the left and right. Dolby Pro Logic II has the MOVIE mode and
MUSIC mode, and the MUSIC mode enables independent adjustment
of three parameters including Panorama mode, Dimension and Center
Width. See page 29 for the Dolby Pro Logic II parameters.
To allow the users enjoy multichannel playback also from the analog
audio of currently available Dolby Surround home video software,
the VR-5900 incorporates a Dolby Pro Logic II surround decoder.
•DTS NEO:6: This is a new technology which decodes 2-channel sig-
nals into 6-channel signals using high-accuracy digital matrix tech-
nology. The DTS NEO:6 decoder has near-discrete properties in the
frequency characteristics of the channels as well as in channel separa-
tion. According to the signals to be played back, DTS NEO:6 uses
either the NEO:CINEMA mode optimized for movie playback or the
NEO:MUSIC mode optimized for music playback.
