FEATURES
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 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 source material that
does not carry surround encoding.
Dolby 3 Stereo uses the information contained in a surround encoded or stereophonic
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 uses decoding similar to Pro Logic, but it permits delay
times up to 90 ms. Use this mode instead of Pro Logic to experiment with
surround times above 30 ms, or if the delay time formula suggests a
larger 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.
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.
