        9. HDMI

        Integra DRX-4.2 comes with 7 HDMI inputs. It has 2 outputs - 1 Main and 1 Sub/Zone2.

        Onkyo TX-SR373 comes with 4 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.
        • Analog To HDMI Upconversion: Integra DRX-4.2 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)

        Integra DRX-4.2 supports HDR10, Dolby Vision and Hybrid Log-Gamma.

        Onkyo TX-SR373 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.

        10. Inputs and Outputs

        Audio

        • Phono Input: There is an MM phono input on Integra DRX-4.2 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
        • Analog Pre-Outs: Integra DRX-4.2 has 11.2 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, Integra DRX-4.2 has 11 channel processing but has only 9 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 6 pair of line inputs on Integra DRX-4.2 and 3 pair of line inputs on Onkyo TX-SR373 for connecting sources with analog outputs.
        • Digital Inputs: 2 optical inputs and 1 coaxial input are available on Integra DRX-4.2 and 1 optical input and 1 coaxial input are available on Onkyo TX-SR373 for digital audio connections.
        • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
