Onkyo has announced two premium AV receivers with support for DTS:X, the audio company's latest surround format that, like Dolby Atmos, adds extra spatial effects to a sound mix.

The receivers also continue Onkyo's recent tradition of support Dolby Atmos and the extra height channels required to accurately render the more immersive cinema soundtracks on offer on some recent Blu-ray releases.

The Onkyo TX-RZ800 and TX-RZ900 receivers also each come with 4K Ultra HD HDMI inputs and outputs, THX Select 2 Plus-certification, and Wi-Fi. They are also AirPlay and Bluetooth-enabled for simple audio hook up and come with Spotify and Deezer software built-in.

The TX-RZ800 is a 7.2 channel receiver (5.1.2 for Dolby Atmos) and is capable of outputting 185W per channel. The TX-RZ900 has the same channel configuration but is capable of outputting 200W per channel.
