The user manual states that you may connect the device to a multi channel receiver (front L&R, rear L&R, center & subwoofer ports) with a Dolby Digital Decoder (does this answer your query, sorry not very audio proficient).Though the player has both Dolby Digital and DTS logos represented on its physical body, the manual, and to an extent my knowledge about the player, is quite ambiguous as to the extent of the player's capabilities regarding either.
