Onkyo announces the addition of eARC (Enhanced Audio Return Channel) to a number of AVRs via firmware update-- an update also bringing native Amazon Music support to a selection of Onkyo hardware.
The firmware update initially activates eARC capability on the 9.2-channel Onkyo TX-RZ830 and Integra DRX-5.2 network AVRs.
ARC technology supports transmission of aduio signals, including LPCM, Dolby Digital and DTS formats, from ARC-compatible TVs or devices connected to the TV. The introduction of eARC enables transmission of object-based audio formats (such as Dolby Atmos and DTS:X) as well as Dolby TrueHD and DTS-H Master Audio lossless audio formats from compatible TVs via single HDMI cable between AVR and display.
