The SA-BX500 features a decoder for the HD Audio (Dolby TrueHD, Dolby Digital Plus and DTS-HD Master Audio) now adopted in Blu-Ray Disc, so users can enjoy the deep, lifelike ambience of 7.1-channel Surround Sound that is a Blu-ray hallmark. Those with only a 5.1-channel speaker system can also enjoy 7.1-channel surround sound thanks to the SA-BX500’s 7.1channel Virtual Surround Sound function.
