        7. Speaker Configurations

        Denon AVR-X550BT's and Pioneer VSX-831's amplifiers can be assigned for different speaker configurations.

        • Configurations: Available configurations are:
        • Denon AVR-X550BT: 5.2 with internal amplifier.
        • Pioneer VSX-831: 5.2 with internal amplifier.
        • Bi-Amp: Pioneer VSX-831 is 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. HDMI

        Denon AVR-X550BT comes with 5 HDMI inputs. It has 1 output.

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

        • 4K/60Hz Passthrough: On both receivers all inputs pass up to 4K 50/60Hz 4:4:4 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)

        Denon AVR-X550BT supports HDR10, Dolby Vision and Hybrid Log-Gamma.

        Pioneer VSX-831 supports HDR10 and Dolby Vision. 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.
