FEATURES
This mode is used 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. Use this mode with DVD, LD or other AC-3 sources
featuring Dolby Digital playback.
Dolby Pro Logic is the standard mode for 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.
Movie Surround processing is similar to Pro Logic and uses matrix surround
decoding, with the option to extend the delay time to 90 ms. Use this to experiment
with surround times above 30 ms, or if the delay time formula suggests a longer time
delay for your room.
This mode is designed for use with stereo recordings. It provides a sound-field effect
that simulates the complex combination of direct and reflected sounds that create
the rich reverberant atmosphere of a medium-sized circular concert hall.
This mode is designed for use with sports broadcasts, live concerts or other programs
where the feeling of a wide surround effect is desired.
This mode turns off all surround processing and presents the pure left and right
channel presentation of two channel stereo programs.
