Listening Mode Definitions
The various listening modes affect signals from any input except the 7.1-channel analog input. Not all listening modes are available for every type of input. For example, modes that generate surround signals from stereo sources cannot be used with DTS or Dolby Digital signals that have discrete digital surround channels, and decoding modes for such digital surround signals won’t work with stereo signals. When you select modes, those not available for your currently selected input simply won’t show up as options. If you switch to an input that your currently selected mode won’t work with, the PRePro will automatically select an appropriate mode (usually, Stereo for stereo sources and Dolby D or DTS for surround sources).
Listening Modes
Stereo: Plays all sources in stereo, through the front left and right channels. When surround input signals are played in stereo mode, the contents of the surround, rear, and center channels are reproduced in the stereo output signal.
Dolby Pro Logic II Movie: Optimized for movies and electronic games, this 5.1-channel mode has more channel separation than Pro Logic, and two full-range surround channels instead of a single, filtered channel. By feeding the two surround speakers slightly different signals, Pro Logic II produces a more spacious, enveloping effect. Unlike the original Pro Logic, it is designed for use with stereo analog or digital signals as well as for films and other two-channel material with Dolby Surround encoding. Available only with two-channel sources.
Dolby Pro Logic II Music: Optimized for music listening, this mode is designed to produce surround ambience from stereo sources such as CDs.
Dolby Digital EX: An enhancement of the original Dolby Digital 5.1-channel surround system, it adds backof-the-room surround information to the information coming from the surround speak- ers at the room’s sides. It can be used with a 6.1-channel speaker setup having one surround back speaker, or with a 7.1- channel setup having two surround back speakers. If the program includes an EX "flag" signal, the PRePro will select this mode automatically. The Dolby EX mode can be selected manually for the many EX DVDs that lack the flag. A list of Surround EX films can be found at www.dolby.com/movies/films_previous.html.
Dolby 2/0: Two channel stereo recordings using the Dolby Digital signal format. Processing modes available are mostly the same as those for stereo CDs.
DTS-ES:An enhancement of the DTS 5.1-channel surround system which adds back-of-the-room surround information. In DTS-ES Discrete soundtracks, this is carried on a discrete, or independ- ent, channel. In DTS-ES Matrix soundtracks, it is encoded as a matrix that is carried by the left and right surround channels. In Setup you can elect to play Surround-back information through one (6.1-channel) or two (7.1-channel) surround-back speakers.
DTS Neo:6 Cinema: For 6.1-channel decoding of movies with surround-encoded, two-channel soundtracks; adds a single rear channel (which can be fed to two surround back speakers); not available in systems with no surround back speakers.
