Advanced Features 32 Surround Mode Chart MODE FEATURES DELAY TIME RANGE DOLBY PRO LOGIC 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 source material that does not carry surround encoding. 15 ms - 30 ms Initial Setting = 20 ms THX CINEMA DOLBY 3 STEREO THX Cinema is a patented process developed by Lucasfilm Ltd. as an enhancement to surround processing. It includes additional enhancements that greatly improve the spectral and spatial realism of motion pictures that are recorded with surround encoding. THX Cinema's exclusive processing is designed to overcome the differences in acoustics between movie theaters and home listening rooms so that movie sound tracks will sound the same way at home as they did in the mixing room where they are created. Use this mode when viewing motion pictures on video. 15 ms - 30 ms Initial Setting = 20 ms Dolby 3 Stereo uses the information contained in a surround encoded 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. No Surround Channels MOVIE SURROUND Movie Surround uses decoding similar to Pro Logic, but it permits delay times up to 90 ms. Use this mode instead of Pro Logic or THX to experiment with surround times above 30 ms, or if the delay time formula suggests a larger time delay for your room. 40 ms - 90 ms Initial Setting = 20 ms HALL SURROUND 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. 10 ms - 90 ms Initial Setting = 20 ms MATRIX SURROUND This mode is designed for use with sports broadcasts, live concerts or other programs 10 ms - 90 ms where the feeling of a wide surround effect is desired. Initial Setting = 20 ms MONO This mode is intended for use with old movies, televisions shows and other programs that have a monaural sound track. All sound will be reproduced through the center channel speaker, if installed. If there is no center channel speaker, monaural sound is reproduced from the front left and right speakers. No Surround Channels STEREO This mode turns off all surround processing and presents the pure left and right channel presentation of two channel stereo programs. No Surround Channels
