        9. HDMI

        Sony STR-ZA3100ES comes with 6 HDMI inputs. It has 2 outputs - 1 Main and 1 Sub/Zone2.

        Yamaha RX-A860 comes with 8 HDMI inputs. It has 2 outputs which work parallelly and output the same signal.

        • 4K/60Hz Passthrough: On both receivers all inputs pass up to 4K/60p (YCbCr4:4:4) video signal.
        • 4K Upscaling: Both receivers can upscale up to 4K/60p from HDMI and analog sources.
        • Analog To HDMI Upconversion: Both receivers support 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 2.2 Copy Protection: Both receivers are 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)

        Both receivers support 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)

        Sony STR-ZA3100ES 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.

        10. Inputs and Outputs

        Audio

        • Phono Input: There is an MM phono input on Yamaha RX-A860 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
        • Analog Pre-Outs: Sony STR-ZA3100ES has 9.2 and Yamaha RX-A860 has 7.2 preamplifier outputs which allow you to connect the receivers to the external power amplifiers. You may want to use a high quality external amplifier for certain channels, usually for front L/R and center, and use the receiver to power the rest. Also, Sony STR-ZA3100ES has 10 channel processing but has only 7 channel amplifier, so it needs external amplifier connected to the analog pre-outs in order to reach its maximum speaker configuration.
        • Analog Line Inputs: There are 4 pair of line inputs on Sony STR-ZA3100ES and 5 pair of line inputs on Yamaha RX-A860 for connecting sources with analog outputs.
        • Digital Inputs: 2 optical inputs and 1 coaxial input are available on Sony STR-ZA3100ES and 2 optical inputs and 2 coaxial inputs are available on Yamaha RX-A860 for digital audio connections.
        • Headphone Output: There is a 6.3 mm (1/4") output jack on Yamaha RX-A860 for headphones.
