        7. Speaker Configurations

        Pioneer VSX-831's and Sony STR-DN1080's amplifiers can be assigned for different speaker configurations.

        • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
        • Pioneer VSX-831: Not supported.
        • Sony STR-DN1080: 5.2.2 with internal amplifier.
        • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
        • Pioneer VSX-831: Not supported.
        • Sony STR-DN1080: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.
        • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
        • Pioneer VSX-831: 5.2 with internal amplifier.
        • Sony STR-DN1080: 5.2, 7.2 with internal amplifier.
        • 2-ch Bi-Amp: Both models are able to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.

        8. Immersive Audio Formats

        Dolby Atmos

        Sony STR-DN1080 supports Dolby Atmos.

        • Dolby Surround Upmixer: Sony STR-DN1080 supports 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

        Sony STR-DN1080 supports DTS:X.

        • DTS Neural:X: Sony STR-DN1080 features 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.

        9. HDMI

        Pioneer VSX-831 comes with 6 HDMI inputs. It has 1 output.

        Sony STR-DN1080 comes with 6 HDMI inputs. It has 2 outputs - 1 Main and 1 Sub/Zone2.

        • 4K/60Hz Passthrough: On both receivers all inputs pass up to 4K/60p (4:4:4 24-bit)
          4K/60p (4:2:0 36-bit)
          4K/24p (4:4:4 36-bit) video signal.
        • 4K Upscaling on Pioneer VSX-831: It can upscale up to 4K from HDMI and analog sources.
        • Analog To HDMI Upconversion: Pioneer VSX-831 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)

        Pioneer VSX-831 supports HDR10 and Dolby Vision.

        Sony STR-DN1080 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)

        Sony STR-DN1080 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.
