DHC-60.7 provides home consumers with an experience "as the director intended" in the cinema. THX spends 40-60 hours testing over 2000 data points ensuring that the DHC-60.7 is capable of meeting rigorous audio and video performance standards for reference level, distortion-free playback and includes THX Loudness Plus technology to bring out intricate details at lower listening levels. The Dolby Surround up mixer expands audio content that is not mixed in Dolby Atmos for playback on any speaker configuration, including overhead speakers- giving a better audio experience even without a Dolby Atmos soundtrack.
