5.1mc MUSIC
The 5.1mc LOGIC 7 MUSIC listening mode is similar to the 5.1mc
LOGIC 7 FILM listening mode, but specifically tailored for music
sources. This mode is designed and recommended for playback of
5.1-channel music sources.
See page 5-35 for detailed parameter descriptions.
5.1mc , 5.1mc UL2Cin, & 5.1mc SurEX
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.
