        8. Immersive Audio Formats

        Dolby Atmos

        Onkyo TX-RZ820 and Sony STR-DH790 support Dolby Atmos.

        • Dolby Surround Upmixer: Both models support Dolby Surround Upmixer. If the content is not mixed in Dolby Atmos then the Dolby surround upmixer will expand the audio to all channels including ceiling speakers. The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.

        DTS:X

        Onkyo TX-RZ820 and Sony STR-DH790 support DTS:X.

        • DTS Neural:X: Both models feature DTS Neural:X which is an advanced upmixer that can take non DTS:X content and upmix it to the DTS:X speaker layout. It has replaced the DTS Neo family with improved flexibility.
        • DTS Dialog Control: Onkyo TX-RZ820 supports DTS Dialog Control. This function adjusts the dialog levels during playback of the DTS:X stream. It allows you to separately increase the dialog levels in contrast with the background sound and hear dialog easily even under noisy circumstances.

        9. HDMI

        Onkyo TX-RZ820 comes with 7 HDMI inputs. It has 2 outputs - 1 Main and 1 Sub/Zone2.

        Sony STR-DH790 comes with 4 HDMI inputs. It has 1 output.

        • 4K/60Hz Passthrough: On both receivers all inputs pass up to 4K/60p (RGB/YCbCr4:4:4) video signal.
        • Analog To HDMI Upconversion: Onkyo TX-RZ820 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 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-DH790 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 Onkyo TX-RZ820 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
        • Analog Pre-Outs: Onkyo TX-RZ820 has 7.2 preamplifier outputs which allows you to connect the receiver to the external power amplifier. 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, both receivers have 7 channel processing but have only 7 channel amplifiers, so they need external amplifiers connected to the analog pre-outs in order to reach their maximum speaker configurations.
        • Analog Line Inputs: There are 6 pair of line inputs on Onkyo TX-RZ820 and 4 pair of line inputs on Sony STR-DH790 for connecting sources with analog outputs.
        • Digital Inputs: 2 optical inputs and 1 coaxial input are available on Onkyo TX-RZ820 and 1 optical input and 1 coaxial input are available on Sony STR-DH790 for digital audio connections.
        • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
