47、HXis an exclusive set of standards and technologies established bythe world-renowned film production company, Lucasfilm Ltd. THXresulted from George Lucas desire to reproduce the moviesoundtrack as faithfully as possible both in the movie theater and inthe home theater.THX engineers developed patent

48、ed technologies to accuratelytranslate the sound from a movie theater environment into the home,correcting the tonal and spatial errors that occur.When the THX mode of the SR-12S1 is on, three distinct THXtechnologies are automatically added:Re-Equalization-restores the correct tonal balance for wat

49、ching amovie in a home environment.These sounds are otherwise mixed to be brighter for a large movietheater. Re-EQ compensates for this and prevents the soundtracksfrom being overly bright and harsh when played in a home theater.Timbre Matching-filters the information going to the surroundspeakers s

50、o they more closely match the tonal characteristics of thesound coming from the front speakers.This ensures seamless panning between the front and surround speakers.Adaptive Decorrelation-slightly changes one surround channels timeand phase relationship with respect to the other surround channel.Thi
