You can select associate one of the digital inputs with the selected input source. Some digital video input sources, such as a cable box or HDTV set-top, may change between analog and digital outputs, depending on which channel is in use. The LR-7500's Auto Polling feature allows you to avoid losing the audio feed when this happens by permitting both analog and digital connections to the same source on the unit Digital audio is the default, and the unit will auto- matically switch to the analog audio if the digital audio stream stops.

Dolby Digital
Available only with digital input sources encoded with Dolby Digital data. It provides up to five separate main audio channels and a special dedicated low-frequency effects (LFE) channel.
Dolby Digital EX
Available when the receiver is configured for 6.1/7.1-chan- nel 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 for 6.1/7.1 operation and a Dolby Digital signal is present, the EX mode is automati- cally 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 5.1
When the speaker configuration is set for 5.1-channel oper- ation, the DTS 5.1 mode is available when DVD, audio-only music or laser discs encoded with DTS data are played. DTS 5.1 provides up to five separate main audio channels and a special dedicated low-frequency channel.
DTS-ES 6.1 Matrix, DTS-ES 6.1 Discrete
When the speaker configuration is set for 6.1/7.1 operation, playback of a DTS-encoded program source will automati- cally trigger the selection of one of the two DTS-ES modes. 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 be decoded using the DTS-ES Matrix mode, which cre- ates a 6.1-channel sound field from the original 5.1-channel soundtrack.
Dolby Pro Logic II (Movie, Music, Pro Logic)
Dolby Pro Logic II is the latest version of Dolby Laboratory's benchmark surround technology that decodes full-range, discrete left, center right, right surround and left surround channels from either matrix surround-encoded programs and conventional stereo sources when an analog input is in use. The Dolby Pro Logic II Movie mode is optimized for movie soundtracks, while the Pro Logic II Music mode should be used with musical selections. The Pro Logic mode activates original Pro Logic processing for those who prefer that presentation.
DTS Neo:6 Cinema, DTS Neo:6 Music
These two modes are available when any analog source is playing to create a six-channel surround presentation from conventional Matrix-encoded and traditional Stereo sources. Select the Cinema version of Neo:6 when a pro- gram with any type of analog Matrix surround encoding is present.
Select the Music version of Neo:6 for optimal processing when a nonencoded, two-channel stereo program is being played.
Dolby Virtual Speaker
Dolby Virtual Speaker uses advanced technology to simu- late the sonic signature of a speaker location even when there is no speaker physically present in that location. The Reference ("REF") mode activates any missing speakers to simulate a 5.1 presentation with accurate localization.
The Wide mode virtualizes the locations of the front-chan- nel speakers to create a wider image and a more envelop- ing sound field. It is available no matter how many speakers are present.
