Yamaha announced three new HDMI 2.1 AV receivers in its flagship AVENTAGE lineup last week, the RX-A8A, RX-A6A, and RX-A4A, which support up to 11.2 channels of audio, Dolby and DTS’s latest sound technologies (e.g., Atmos), and 8K/60 Hz and 4K/120 Hz output. According to a separate advisory, none of these receivers are affected by the bug that had prevented many HDMI 2.1 receivers from properly passing through 4K/120 Hz content from select devices such as the Xbox Series X. Yamaha warned that these units will still require a future firmware update to enable “certain HDMI 2.1 capabilities,” however.
[…] these new AVENTAGE models will include industry-leading support for the latest HDMI technology, with seven inputs and three outputs in each model supporting 8K60/4K120. This HDMI 2.1 compatibility provides faster, smoother and uninterrupted entertainment and gameplay with auto low latency mode (ALLM), variable refresh rates (VRR), quick frame transport (QFT) and quick media switching (QMS). The RX-A8A, RX-A6A and RX-A4A support immersive 3D audio with Dolby Atmos and DTS:X, enabled by the Qualcomm QCS407 smart audio platform.
