FEATURES
This mode is available only when the source material is encoded with Dolby Digital
(AC-3) data. It provides up to five separate main audio channels and a special
dedicated Low-Frequency Effects channel.
This mode is available only when the source material is encoded with DTS data.
Available on special DVD, LD and audio-only discs, DTS provides up to five separate
main audio channels and a special dedicated low-frequency channel.
Dolby Pro Logic is the standard mode for analog surround sound decoding. It uses
information encoded in a two-channel stereo recording to produce four distinct
channels: Left, Center, Right and Surround. Use this mode for accurate reproduction
of programs bearing the Dolby Surround, DTS Stereo, UltraStereo or other
“Surround” logos. Surround encoded programs include videocassette, DVD and LD
movies, TV and cable programs, radio programs and audio CDs. Dolby Pro Logic
processing may also be used to provide a pleasing surround effect with some
stereophonic source material that does not carry surround encoding.
Dolby 3 Stereo uses the information contained in a surround encoded or two-channel
stereo program to create center channel information. In addition, the information
that is normally sent to the rear channel surround speakers is carefully mixed in with
the front left and right channels for increased realism. Use this mode when you have a
center channel speaker, but no surround speakers.
Theater Surround processing uses matrix surround decoding to simulate a standard
movie or stage theater.
These modes are designed for use with stereo recordings. They provide a sound-field
effect that simulates the complex combination of direct and reflected sounds that
create the rich reverberant atmosphere of a medium-sized concert hall (Hall 1) or a
larger concert hall (Hall 2).
This mode turns off all surround processing and presents the pure left and right
channel presentation of two channel stereo programs.
