Dolby Pro Logic IIx expands stereo or 5.1-channel audio to 6.1- or 7.1-channel sound, and lets you customize audio playback with listening modes designed specifically for movies, music, and games.
By expanding your listening environment with 6.1 or 7.1 channels of sound, Dolby® Pro Logic® creates a seamless, natural soundfield and a more realistic audio experience.
Select a listening mode—Movie, Music, or Game—to adjust the audio playback for the best possible sound, no matter what your choice of entertainment.
Movie mode decodes movie soundtracks with the same audio mixing format used to encode most movie surround soundtracks, so you get the audio that the director intended.
Game mode adds impact to video games by reproducing full-range special effects to your surround channels.
Music mode produces natural and balanced surround sound from stereo content.
