TX-NR646 and TX-NR747 network A/V receivers from Onkyo & Pioneer Corporation deliver reproduction of new DTS:X™ and Dolby Atmos® object-based audio formats for multidimensional entertainment experience at home.
With a FW update coming later in the year to add DTS:X, DTS:X scales to any home theater configuration up to 7.1.4 channels. Further, DTS:X incorporates Neural:X, the latest spatial remapping technology from DTS, which provides a fully immersive output for all types of source content.
The TX-NR646 generates an impressive 160 W/Ch of power while the TX-NR747 outputs 175W/Ch and is THX® Select 2™ Plus certified to guarantee theater-reference volume with minimal distortion. Both receivers are fitted with Dual 32-bit DSP Engines and a new 384 kHz/32-bit AK4458 DAC from Asahi-Kasei for transparent reproduction of music and soundtracks.
Joining next-generation audio decoding are eight 4K/60 Hz-ready HDMI® 2.0a inputs and two multi-zone outputs, including dedicated HDCP 2.2-compliant terminals for 4K streaming and UltraHD Blu-ray with Dolby Atmos or DTS:X audio (due later this year). High Dynamic Range (HDR) color and 21:9 cinema-aspect are also supported.
Both receivers are set up for wireless audio with Wi-Fi®, AirPlay, and Bluetooth. Onkyo’s new Remote App 3 streams digital music stored on mobiles while accessing a generous selection of Internet radio and on-demand music services.
Streaming via Spotify app is also supported, while users can enjoy 192/24 FLAC and DSD 5.6 MHz Hi-Res Audio files via DLNA, or use the phono equalizer input to connect a turntable.
Both models are now available in black, Onkyo 646 is retailing at $1,299 and Onkyo 747 is retailing at $1,699. Both models are available from 24 July 2015 at Alpha Audio, Audio House, Courts, and Harvey Norman.
