Available on special Delay not adjustable 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 The standard mode for analog surround sound decoding. It uses information encoded in a two-channel stereo recording to produce four distinct outputs: Left, Center, Right and a Mono Surround channel. 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 LOGIC 7 C LOGIC 7 M An advanced mode that extracts the maximum surround information from either surround-encoded programs or conventional stereo material. When used with encoded material, decoding is more accurate in terms of the placement of sounds, and fades and pans are much smoother and more realistic than with other decoding techniques. Logic 7 also delivers increased spaciousness and a wider sound stage when it is used with conventional stereo recordings and music programs. The Logic 7C or Cinema mode is tailored to provide an optimal sound field for movie soundtracks. The Logic 7M or Music mode uses a decoding formula that is best suited to music. Delay time not adjustable DOLBY 3 STEREO THEATER VMAx 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 front-right channels for increased realism. Use this mode when you have a center-channel speaker but no surround speakers. No surround channels Surround processing uses matrix surround decoding to simulate a standard movie or stage theater. 27.3 ms (not adjustable) When only the two front-channel loudspeakers are used, Harman's patented VMAx mode delivers a three-dimensional sound space with the illusion of "phantom speakers" at the center and surround positions. No surround channels This mode turns off all surround processing and presents the pure left and right channel presentation of two-channel stereo programs. No surround channels 22 OPERATION
