[. . . ] There are three cinema modes: STANDARD, HOME THX CINEMA, and ADVANCED THEATER. These are designed to be used with multi channel surround sound audio/visual sources (like DVDs and LDs). Intrinsic to home theater, these modes can deliver realistic and powerful surround sound that recreates the movie theater experience. You may need to experiment with them to see which settings suit your home system and personal tastes. The DSP and STEREO modes are designed to be used with music sources but some DSP modes are also suited for film soundtracks. Again, try different settings with various soundtracks to see which you like. You must choose one of the three cinema modes or the DSP mode in order to get surround sound. In STEREO mode only the front two speakers are used. STANDARD mode This mode is for pure decoding of Dolby Digital, DTS and Dolby Pro Logic. It is good for enjoying regular movies that have been recorded in Dolby Digital, DTS or Dolby Pro Logic. HOME THX CINEMA mode THX is a set of technical standards created by Lucasfilm, Ltd. These standards were designed to emulate a film sound stage and thus reproduce, with the greatest possible accuracy, the soundtrack intended by the filmmakers. 71 ADVANCED THEATER modes The Advanced Theater mode is a newly designed system for enhancing movie soundtracks and other audio-visual sources. · Use DIGITAL NR See front panel explanations on p. 16-17 and display explanations on p. 18 for details on SPEAKERS (A/B), LOUDNESS, BASS (+/­) and TREBLE (+/­). memo When listening to Dolby Digital or DTS sources, DIGITAL NR does not function even if you select STEREO. OPERATION 35 Basic Playback Selecting a Sound Mode To ensure the best possible surround sound, be sure to complete the set up procedures described in "Setting Up for Surround Sound" (starting on page 23) before using the sound modes.
