Dolby Atmos and DTS:X surround sound technologies dispense with channel-based coding in favour of object-based coding, giving the sound designer the ability to precisely place sounds anywhere in the 3-dimensional space. The AV7703, features the ability to connect a 7.1 surround sound speaker system and 4 additional overhead speakers (or 4 additional Dolby Atmos elevation speakers) via separate power amplifiers for the ultimate home cinema experience. Dolby Surround Upmixer and DTS Neural:X Upmixer are also in place to simulate 3D sound from standard formats.

Auro-3D Upgradeable: By fully immersing the listener in a cocoon of life-like sound, Auro-3D puts you right in the middle of the action. Auro-3D provides an immersive surround sound experience thanks to dedicated height and overhead channels, in addition to the regular channels. The height information, captured in recording or created during the mixing process, is mixed into a standard 5.1 PCM stream that comes with a regular Blu-ray. Moreover, the Auro-3D engine recognizes mono, stereo, 5.1 surround or an Auro-encoded signal and transforms them into 3D audio. Once upgraded with the Auro-Codec decoder, the AV7703 is capable of decoding the original Auro-3D mix and playing back an Auro-3D 10.1 channel configuration (with external amplifier). Auro-3D upgrade availability and pricing to be announced. (available early 2017)
