It provides up to five separate main audio channels and a special dedicated Low-Frequency Effects channel.Dolby Digital EXAvailable when the receiver is
14、 configured for 6.1/7.1-channel operation, Dolby Digital EX is the latest version of Dolby Digital.When used with movies or other programs that have special encoding, Dolby Digital EX reproduces specially encoded soundtracks so that a full 6.1/7.1 sound field is available.When the receiver is set fo
15、r 6.1/7.1 operation and a Dolby Digital signal is present, the EX mode is automatically selected. Even if specific EX encoding is not available to provide the additional channel, the special algorithms will derive a 6.1/7.1 output.DTS 5.1When the speaker configuration is set for 5.1-channel operatio
16、n, the DTS 5.1 mode is available when DVD, audio-only music or laser discs encoded with DTS data are played.

Newer discs with special DTS-ES discrete encoding will be decoded to provide six discrete, full-bandwidth channels plus a separate low-frequency channel.All other DTS discs will
18、 be decoded using the DTS-ES Matrix mode, which creates a 6.1-channel sound field from the original 5.1-channel soundtrack.Dolby Pro Logic IIDolby Pro Logic II is the latest version of Dolby Laboratorys benchmark surround technology that decodes full-range, discrete left, center right,Movieright sur

Depending on the number of speakers in use and the selection made in the Logic 7 EnhanceSURROUND SELECT menu, the “5.1” versions of Logic 7 modes are available when the 5.1 option is chosen, while the “7.1” versions of Logic 7 produce a full sound field presentation, including back su
22、rround speakers when the “6.1/7.1” option is chosen.The Logic 7 C (or Cinema) mode should be used with any source that contains Dolby Surround or similar matrix encoding. Logic 7 C delivers increased center-channel intelligibility, and more accurate placement of sounds with fades and pans that are m

Logic 7 M enhances the listening experience by presenting a wider front soundstage and greater rear ambience. Both Logic 7 modes also direct low-frequency
24、 information to the subwoofer (if installed and configured) to deliver maximum bass impact.The Logic 7 E (or Enhance) mode, available only when the 5.1 option is chosen,is an extension of the Logic 7 mode that is primarily used with musical programs. Logic 7 adds additional bass enhancement that cir
