Optical lang ang digital input nito so if you use it, it should decode the DTS signal. Been using it in the office and dun nakainput yung audio ng bluray player but its downmixed to standard DTS since bd discs audio are usually encoded with DTS-HD Master. Ok lang yun except yung Apocalypse Now audio di nya ma-decode. Don't know why kaya sa tv lang yung audio nung pinanuod ko dito sa office,
