Denon and Marantz Launch New 8K Receiver Ranges
Marantz and Denon have both released new receivers that support 8K.
The AV 10 is the flagship for Marantz, which also has a new high-end Cinema line with four models, the 40, 50, 60, and 70. All have HDMI 2.1 with support for 8K and HDR, including Dolby Vision. Reflecting the change in technology to digital sources, all but the 40 modle drops support for composite and component video. Scaling from 1080P to 8K is supported, and more details are listed here.
Denon also has a new range that starts at lower prices than Marantz, and even the $399 AVR-S570BT entry-level product has 8K/60Hz, 4K/120Hz, HLG, HDR, Dolby Vision, HDR10+ pass-through, and 8K upscaling on all four HDMI inputs and one output, for maximum bandwidth up to 40Gbps (8K/60p 4:2:0).
We have published several articles on the 8K Association website that digs into upscaling. This technology is crucial for 8K as the content industry scales up to create and supply 8K content. The first article looks at the theory of upscaling and digs into how the technology has rapidly developed in the last couple of years. AI, big data, and machine learning have become available to TV designers and have improved the quality of upscaling.
The second article examines where upscaling is best done in typical home TV setups.
