Surround Mode Options
Surround sound processing enables four separate audio signals to be transmitted within the left and right channels of a videocassette, radio or TV broadcast, or video disc. Through a process known as matrix encoding a separate center chan- nel signal for dialog and a surround channel for effects are encoded into the stereo signal. When you see the Dolby Surround™, Dolby Stereo™, DTS Stereo™ or other similar logos on a movie or broadcast this indicates that the program has surround information.
When the program you are listening to has encoded surround information, as shown by one of the logos or brand
names described above, select the ProLogic mode using the front panel or remote Surround Mode Selectors
6h.
If a center channel speaker is used along with front left/right speakers, but no sur- round speakers are used, choose the Dolby 3 Stereo mode6h. This combines the surround signal into the front left and right channels to create a greater feeling of presence and a more expansive sound field than with conven- tional stereo signals. Center channel dia- log information will continue to be heard through its proper place at center screen.
When listening to conventional stereo recordings or programs, those with sepa- rate left and right channels but no inten- tionally recorded surround information, you may wish to experiment with the surround modes to see which produces the effect you prefer. Stereo recordings often contain sufficient natural phase differences so that the ProLogic or Dolby 3 Stereo Modes are enjoyable, despite the lack of true surround infor- mation.
Stereo recordings may also sound more expansive in either the Theater or Stadium modes. Selecting these modes 6huses the front left and right speakers for normal stereo, while the sur- round speakers are fed a reverberated sound. In order to provide for a wider variety of sound field effects, the sur- round channel delay available in the Theater and Stadium modes is substan- tially greater than that in Dolby ProLogic.
NOTE: The center channel speaker is not operational in the Theater or Stadium modes.
