The 5.1mc THX, 5.1mc THX UL2Cin, and 5.1mc THX SurEX listening modes are designed to convert 5.1-channel film sources that lack THX Surround EX encoding into seven channel audio. The modes also allow 5.1-channel sources to use bass management, speaker crossovers, speaker distance calibration, and audio controls (tone controls). The 5.1mc THX, 5.1mc THX UL2Cin, and 5.1mc THX SurEX listening modes are recommended for home theaters with THX-certified speakers. These modes 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-equalization.

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

The listening mode name differs depending on the SURROUND EX parameter setting, and the speaker setup.

The table below indicates the conditions in which THX Ultra2 and THX Surround EX decoding are activated.
