Yamaha launched Monday its new RX-V AV receiver line with a pair of models supporting the HDR10+ high dynamic range (HDR) profile and a number of HDMI 2.1 technologies for advanced gaming and 8K video.

The two 2020 RX-V line models include the RX-V4A ($439.95 suggested retail) and RX-V6A ($599.95), offering five and seven channels of support, respectively. The RX-V6A will hit retailers in September and the RX-V4A will be available this month.

Both models are said to be ready to support and pass through many of the latest 4K and 8K capabilities, including such advanced HDMI 2.1 features as auto low latency mode (ALLM), variable refresh rates (VRR), quick frame transport (QFT) and quick media switching (QMS). Coming via a future firmware update will be up to 8K/60 Hz and 4K/120 Hz frame rates.

Both units also support the new HDMI 2.1 enhanced audio return channel (eARC) feature enabling greater bandwidth for support of lossless streaming audio codecs, better lip-sync accuracy, and multi-component interoperability, among other benefits.

The company said “no other AV receiver on the market offers as many 8K HDMI inputs as Yamaha.” Three of 7 HDMI inputs on the RX-V6A offer 8K support while all four inputs on the RX-V4A support it.

Yamaha said many of the new HDMI 2.1 features supported in the models will be coming to the AVRs via a future firmware update. The additions are said by Yamaha to be “especially helpful for compatibility not only with Ultra HD TVs and emerging 8K setups, but also in preparation for the latest gaming platforms arriving this fall.”

Another new feature available (coming to the RX-V6A in a firmware update) is Dolby Height Virtualization, which was developed to simulate the overhead sound experience of Dolby Atmos through speakers at regular listener levels, when true overhead speakers aren’t available. The technology works by applying height cue filters to overhead audio components in the surround sound mix.

Cosmetically speaking, Yamaha has modernized the look of the AVRs with a simplified, modern design that features a new, high-resolution LCD display and a jog dial with touch-sensitive buttons.

Both models expand support via HDMI for popular high dynamic range video profiles, with the HDR10+ technology with dynamic metadata, joining the baseline HDR10, Dolby Vision (dynamic metadata) and Hybrid Log-Gamma (HLG) HDR profiles. HDR10+, which is supported in Samsung 4K and 8K TVs among others, is available via 4K content from Google Play Movies, Amazon Prime and others.
