Yamaha unveiled the next generation of its premium Aventage network AV receivers, which now support both Dolby Atmos and DTS:X object-based surround decoding out of the box in all six 2016 models, as well as 4K Ultra HD with HDR streaming via HDMI 2.0a/HDCP 2.2 inputs.
The company said it developed the series with the level of craftsmanship that Yamaha has used in developing its lines of musical instruments.
All models will pass through the latest 4K/HDR video signals over HDMI 2.0a/HDCP inputs and outputs. These will support up to: 3840×2160 resolution; 4:4:4 chroma subsampling; up to 60Hz frame rates; 12-bit color and HDR metadata.
The entry model (RX-A660) this year begins at a $649.95 suggested retail with the top of the line model offered at $2,199.95. Step-up models in the series starting at $1,699 feature 9.2-channel amplification with Dolby Atmos/DTS:X processing. This enables object-based surround sound-speaker configurations of 5.1.4 and 7.1.2.
The flagship RX-A3060, which carries a $2,199 suggested retail, features 9.2-channel amplification with 11.2-channel processing and, with the addition of an outboard two-channel amp, will drive speaker configurations up to 7.1.4.
