These modes are designed for 7-channel playback of 5.1-channel Dolby Digital film sources that do not have THX Surround EX encoding. They apply THX re-equalization to simulate high-frequency rolloffs that occur in movie theaters. Most films are mixed for movie theaters, and might sound too bright when played back in home theaters without re-equal- ization. THX timbre matching is applied to minimize timbre differences between the front and surround channels, which results in smoother sound movements between them. These modes are recommended for home theaters with THX-certified speakers.

The listening mode name differs, depending on the encoding present in the input source, the SURROUND EX parameter setting and the speaker setup.

The table at the bottom of the page shows the conditions for the behavior of the THX Ultra2 and THX Surround EX modes when activated:

•The THX UL2Cin listening mode is available when both the side and rear speakers are present and THX ULTRA2 decoding is engaged. THX Ultra2 decoding is engaged when the SURROUND EX parameter is set to OFF or AUTO and a non-flagged

5.1-channel Dolby Digital source with or without THX Surround EX encoding is detected.

•The THX SurEX listening mode is available when both the side and rear speakers are present and THX Surround EX decoding is engaged. THX Surround EX decoding is engaged when the SURROUND EX parameter is set to ON or AUTO and a flagged 5.1-channel Dolby Digital source with THX Surround EX encoding is detected.

•The THX listening mode is available when both Ultra2 and THX Surround EX decoding are deactivated.

Note:

Some EX-encoded sources are not flagged, and require manually setting the SURROUND EX parameter to ON for EX decoding.

When THX Ultra2 decoding is active:

•Adaptive de-correlation is applied to increase the perceived width of the listening space. De-correlation of the mono surround channel increases the perceived width of the surround field in home theaters.
