Dolby Vision compatibility is newly supported, too. HLG (Hybrid Log Gamma) passthrough is supported for coming HDR broadcasting contents. eARC (Enhanced Audio Return Channel) willl be supported via firmware update.

Full wireless connectivity is provided via both Wi-Fi and Bluetooth, Apple Airplay is supported for music streaming, and built-in HEOS wireless multi-room audio technology allows the AVR-X6400H to become the heart of a whole-house wireless multi-room music network.

As well as the HEOS app, the “Denon 2016 AVR Remote” app is also available free from the Apple app store, GooglePlay and the Amazon appstore for your smartphone or tablet.
