        7. Speaker Configurations

        Denon AVR-S730H's and Onkyo TX-RZ820's amplifiers can be assigned for different speaker configurations.

        • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
        • Denon AVR-S730H: 5.2.2 with internal amplifier.
        • Onkyo TX-RZ820: 5.2.2 with internal amplifier.
        • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
        • Denon AVR-S730H: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.
        • Onkyo TX-RZ820: 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:
        • Denon AVR-S730H: 5.2, 7.2 with internal amplifier.
        • Onkyo TX-RZ820: 5.2, 7.2 with internal amplifier.
        • Bi-Amp: Onkyo TX-RZ820 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. Immersive Audio Formats

        Dolby Atmos

        Denon AVR-S730H and Onkyo TX-RZ820 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

        Denon AVR-S730H and Onkyo TX-RZ820 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 Virtual:X: Denon AVR-S730H supports DTS Virtual:X which bridges the gap between DTS:X codec and the reality of so many consumers' homes, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. If you have a limited speaker setup you will miss a full immersive potential of your entertainment system. DTS Virtual:X adds height and surround audio effect to your system without adding height speakers. It works with multiple configurations and delivers immersive sound experience out of 5.1 or even 2.1 speaker layouts.
        • DTS Dialog Control: Both models have 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

        Denon AVR-S730H comes with 6 HDMI inputs. It has 1 output.

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

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


        Gaming Features

        Denon AVR-S730H supports Auto Low Latency Mode (ALLM) for lag-free and smooth gaming.

        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 2 pair of line inputs on Denon AVR-S730H and 6 pair of line inputs on Onkyo TX-RZ820 for connecting sources with analog outputs.
        • Digital Inputs: 2 optical inputs and 1 coaxial input are available for digital audio connections on both receivers.
        • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
