No 4k 120fps HDMI bug for new Yamaha Aventage AV receivers

Yamaha has unveiled a new trio of Aventage AV receivers, which it says do not suffer from the HDMI v2.1 4k High Frame Rate bug which has afflicted rivals.

The RX-A8A, RX-A6A and RX-A4A, offering 11-, 9- and 7-channels respectively, will feature no fewer than seven HDMI 2.1 inputs supporting 8k60/4k120 each.

The £3,299 RX-A8A is a 150-watt design; the £2,299 RX-A6A a 150-watt model; the £1,299 RX-A4A a 110-watt receiver. All are available from August.

Simon Feben-Harknett, AV Product Specialist, said: “The HDMI 2.1 bug will not affect these products, as the delay in manufacturing has meant we were able to ensure compatibility with new source devices. All that will be required is a firmware update to unlock these new functions, expected to arrive later in the year.”

Hailed as the biggest update to the Aventage line yet, these new AVRs sport a new simplified cosmetic design with a centered volume knob, high-resolution LCD display, rotary jog dial and touch-sensitive buttons.They also sport a new version of the brand’s signature ‘fifth foot’, an Anti-Resonance Technology wedge which promises more efficient dispersion of chassis vibration.

Dolby Vision and HDR10+ compatible, the models support auto low latency mode (ALLM), variable refresh rates (VRR), quick frame transport (QFT) and quick media switching (QMS).

Codec support covers Dolby Atmos and DTS:X, with Height Virtualization, delivered by a new Qualcomm QCS407 smart audio platform. The top two models also offer Auro-3D.

In addition, all models feature Surround:AI, a proprietary Yamaha technology which analyzes the DSP parameters and optimizes each sound element, such as dialogue, background music and sound effects, in real time. The three new AVENTAGE models double the previous platform with 64-bits of processing power, thanks to the Qualcomm QCS407 chip.

Other features include Yamaha Parametric room Acoustic Optimizer, (YPAO) Reflected sound control, Multi-point measure, Precision EQ and a new Low frequency mode.

More news on the HDMI 2.1 fix for Yamaha’s RX-V4, RX-V6, RX-A2 is expected next week.
