This blu-ray audio requires a blu-ray player. Decoding the Dolby Atmos Mix requires a Dolby Atmos certified soundbar or a Dolby Atmos compatible receiver or amplifier, with appropriate speaker set-up. The Dolby Atmos Mix will play on 5.1 systems. It will 'fold down' to 5.1 if an Atmos decoder is not detected and sounds in elements that are unique to Atmos (e.g. 'height' speakers) will get player via other channels.
