Onkyo TXNR646 (Black)
Atmos AV Receiver
Out of stock
Check out what has to be the home cinema sensation of the year! The Onkyo TXNR646 is the first affordable AV receiver equipped with both DTS:X and Dolby Atmos and truly ahead of its time.
Introducing DTS:X
DTS:X is the flagship processor from this highly respected tech company and literally pushes the boundaries of what you can expect from home cinema. This highly sophisticated processor renders images in three dimensions that conventional processing can't match. It also offers other advantages such as the ability to boost the spatial effect of conventional DTS and easily adapts with your existing speaker configuration.
Engineered for Dolby Atmos sound
Optimised for Dolby Atmos, you can be amongst the first to experience the wonder of Dolby Atmos in your own home. Producing a multi-dimensional and totally immersive sound, Dolby Atmos has been hailed as the greatest advance in surround sound for 20 years - so don't miss out!
A powerful performer
Making sure you feel the full impact of DTS:X and Atmos, the Onkyo TX-NR646 boasts a powerful 100w per channel amplifier . The high current design with WRAT (Wide Range Amplifier Technology) and discrete circuitry easily sustains powerful but testing dynamics such as explosions and intense action scenes.
High Resolution sound
As well as offering multi-dimensional surround sound, the Onkyo TXNR646 is compatible with High-Resolution Audio. This gives the highest sound quality, that's far more natural sounding than standard audio. The premium 384kHz/32-bit DAC is compatible with a wide range of HD audio formats, including DSD 5.6 MHz and FLAC 192kHz-24-bit for exceptional sound quality.
Wi-Fi with Spotify and AirPlay
Connect via Ethernet or wi-fi to your home network and gain access to a whole new world of entertainment. From here you'll be able to access a massive range of Internet radio stations plus music services such as the hugely popular Spotify and Deezer. New to this year's model is the introduction of AirPlay, making it easier than ever to stream from your Apple iOS devices, too.
Stream music from your mobile with Bluetooth
With a Bluetooth receiver built in, it's easy to enjoy your music from other devices. Pair with your smartphone, tablet, laptop or PC and wirelessly stream all your favourite music. With the possibility of streaming music services, such as Spotify, Deezer and Tidal, as well as your own music library, you get access to near unlimited music! Advanced Music Optimiser improves the dynamic response from compressed music sources, adding 'sparkle' to the sound and restoring the sound quality.
The latest connections
As you'd expect from this leading AV brand, the TXNR646 comes with the latest connectivity. The TXNR646 features the latest HDMI 2.0a connections and supports HDCP 2.2, which means you can stream UltraHD video and that it's ready for the next generation of 4K discs. With twin HDMI outputs you can also have a second AV display in another room.
Take a listen to just how far home cinema has come in the past few years. With the DTS:X and Dolby Atmos-equipped Onkyo TXNR646 home cinema has never sounded so real.
