Advanced Features 31 The first time a PCM source is played the AVR85 will automatically select the Stereo mode, but you may then select any surround mode desired. Recording When Digital Sources Are In Use Since the record outputs of the AVR85 are traditional two-channel stereo, the multichannel outputs of a Dolby Digital signal are not available for recording. When a Dolby Digital signal is being played, the accompanying analog audio signal is sent to the Tape Out and VCR Out jacks £∞fj. The video source being output is the last selected video input shown in the Visual indicator Q. Surround Mode Chart MODE FEATURES DELAY TIME RANGE DOLBY DIGITAL This mode is used only when the source material is encoded with Dolby Digital (AC-3) Center: 0 ms - 5 ms data. It provides up to five separate main audio channels and a special dedicated Low- Surround: 0 ms - 15 ms Frequency Effects channel. Use this mode with DVD, LV or HDTV sources. 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, 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. 15 ms - 30 ms Initial Setting = 20 ms DOLBY 3 STEREO 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. No Surround Channels MOVIE SURROUND Movie Surround processing uses matrix surround decoding, with the option to extend 40 ms - 90 ms the delay time to 90 ms. Use this to experiment with surround times above 30 ms, or if Initial Setting = 40 ms the delay time formula suggests a longer time delay for your room. 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. 40 ms - 90 ms Initial Setting = 40 ms MATRIX SURROUND This mode is designed for use with sports broadcasts, live concerts or other programs 40 ms - 90 ms where the feeling of a wide surround effect is desired. Initial Setting = 40 ms 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
