Onkyo AVRs Combine Atmos, DTS:X, HDMI 2.0a

Upper Saddle River, N.J. — Onkyo plans June shipments of its first two AVRs to support two object-based surround formats: Dolby Atmos and DTS:X.

DTS:X will be available as a firmware upgrade sometime later this year.

The TX-NR646, due in early June at a suggested $699, and the TX-NR747, due in late June at a suggested of $999, will also be the brand’s first AVRs with HDMI 2.0a inputs and outputs, which pass through high dynamic range (HDR) video formats to a compatible TV.

Both are networked 7.2-channel models that support a 5.1.2 Dolby Atmos or DTS:X speaker configuration. An outboard amp can’t be added to support a 5.1.4 speaker configuration, a spokesperson said.

Both models also feature HDCP 2.2 copy protection on three of eight HDMI inputs and both HDMI outputs to pass through copy-protected UltraHD 4K video from future 4K IP set-top boxes and 4K Blu-ray players to 4K TVs equipped with HDCP 2.2.

The AVRs are also the company’s first with HDMI/HDCP2.2 inputs and outputs that support full-bandwidth 18Gbps HDMI instead of 10.2Gbps HDMI. The change enables the AVRs to pass through 4K video at 60fps with 4:4:4 color sampling, a step up from 4:2:0 color sampling.

They’re also the company’s first AVRs with Apple AirPlay and first with 384kHz/32-bit DACs.

Later this year, the company will unveil additional AVRs at lower price points with Dolby Atmos, 18Gbps HDMI 2.0a, and HDCP 2.2 but without DTS:X, a spokesman said. In its 2014 lineup, Onkyo started Dolby Atmos at a suggested $699, HDCP 2.2 at $699, and HDMI 2.0 without HDCP 2.2 at $299. DTS:X was unavailable in the 2014 line.

Both new models also feature built-in Wi-Fi, DLNA 1.5, and high-resolution 192kHz/24-bit and DSD 5.6MHz music streaming over DLNA, though DSD streaming requires a wired Ethernet connection. They also feature phono input to connect turntables.

In the 2014 lineup, embedded Bluetooth started at $299, and built-in Wi-Fi, DLNA 1.5 and DSD 5.6HMz streaming playback started at $499.

Here’s what each AVR offers:

The $699 TX-NR646 features 7×100-watt output from 20Hz to 20kHz into 8 ohms with 0.08 percent THD and two channels driven. Other key features include eight HDMI inputs, including a front input, and two HDMI outputs, each enabling video output to a separate room. Three HDMI inputs and both outputs support HDCP 2.2.

Streaming services include TuneIn Radio, Pandora, Slacker, SiriusXM Internet Radio, Spotify and Deezer. Other features include mass-storage class USB, Made for iPod/iPhone/iPad USB, AccuEQ room acoustics calibration, and powered audio-zone two.

The $999 TX-NR747 adds 7×110 watts per channel amplification, THX Select2 Plus certification, and a whole-house mode for sending synchronized audio throughout the house. Details on that capability were unavailable.
