Listening mode menu option and parameter descriptions begin on page 5-28.

•Designed for playback of 5.1-channel Dolby Digital film sources.

•Listening mode name differs depending on the encoding present in the input source, the SURROUND EX parameter setting, and the speaker setup. The table on the next page indicates the conditions in which THX Surround EX and THX Ultra2 decoding are engaged.

•Allows 7-channel playback of 5.1-channel Dolby Digital sources without Surround EX encoding.

•Applies 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-equalization.

•Applies THX timbre matching to minimize timbre differences between the front and surround channels, which results in smoother sound movements between them.

•When the 5.1 THX ULTRA2 listening mode is activated, ASA processing is applied to signals sent to the rear speakers. Refer to the ASA parameter description on page 3-34 for more information.

•When the 5.1 THX ULTRA2 listening mode is activated, adaptive de-correlation increases 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.

•When the 5.1 THX SurEX listening mode is activated, matrix decoding derives three surround channels from 5.1-channel Dolby Digital sources.

•Recommended for home theaters with THX-certified loudspeakers.
