        9. HDMI

        Denon AVC-S660H comes with 3 HDMI 2.1 inputs with 8K support and 3 inputs with 4K support. It has 1 output.

        Marantz NR1606 comes with 8 HDMI inputs. It has 1 output.

        • 8K/60Hz and 4K/120Hz Passthrough on Denon AVC-S660H: 3 out of 6 inputs pass up to 8K 50/60Hz (YCbCr 4:2:0/8-bit) and 4K 100/120Hz (RGB/YCbCr 4:4:4/8, 10-bit and YCbCr 4:2:2/12-bit) and the rest of the inputs pass up to 4K 50/60Hz 4:4:4 video signal.
          4K/60Hz Passthrough on Marantz NR1606: All inputs pass up to 4K 50/60Hz 4:4:4 video signal.
        • 8K Upscaling on Denon AVC-S660H: It can upscale from 1080p and 4K up to 8K 50/60Hz and 4K 50/60Hz from HDMI sources.
          4K Upscaling on Marantz NR1606: It can upscale up to 4K 30/25/24p 4:4:4 from HDMI and analog sources.
        • Analog To HDMI Upconversion: Marantz NR1606 supports analog to HDMI Upconversion, so you can input your analog video sources and output them digitally via HDMI. This means that you will need only one HDMI cable to connect to your TV.
        • BT.2020 Color Space: BT.2020 or Rec. 2020 is a color standard which delivers a wider color gamut compared to Rec. 709. It covers approximately 75% of the total visual spectrum while the Rec. 709 covers only 35% (available on both models).
        • HDCP Copy Protection: Denon AVC-S660H is HDCP 2.3 and Marantz NR1606 is HDCP 2.2 compliant which is a requirement for 4K/HDR copy-protected content transmission.
        • 3D Ready: Both receivers are able to pass 3D video through HDMI.

        HDR (High Dynamic Range)

        Denon AVC-S660H supports HDR10, HDR10+, Dolby Vision, Dynamic HDR and Hybrid Log-Gamma.

        Marantz NR1606 supports HDR10, Dolby Vision and Hybrid Log-Gamma. High dynamic range video has greater dynamic range than standard dynamic range (SDR) video with brighter whites and deeper blacks. The result is greater contrast and more details in dark and bright areas, better color and depth.


        Enhanced Audio Return Channel (eARC)

        Denon AVC-S660H supports Audio Return Channel (ARC) which allows the compatible TV to send audio signal to the a/v receiver through the same HDMI cable which is used to send audio and video signals to the TV. So one HDMI cable is used to transfer audio signal in both directions. New Enhanced ARC will support uncompressed audio formats such as Dolby Atmos, DTS:X, Dolby TrueHD and DTS HD Master Audio whereas the previous ARC could support only Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.


        Gaming Features

        Denon AVC-S660H supports Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.
