        7. Speaker Configurations

        Denon AVR-X6500H's and Marantz NR1508's amplifiers can be assigned for different speaker configurations.

        • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
        • Denon AVR-X6500H: 5.2.2, 5.2.4, 7.2.2, 7.2.4 with internal amplifier.
        • Marantz NR1508: Not supported.
        • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
        • Denon AVR-X6500H: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2, 5.2.4, 7.2.2, 7.2.4 with internal amplifier.
        • Marantz NR1508: Not supported.
        • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
        • Denon AVR-X6500H: 5.2, 7.2 with internal amplifier.
        • Marantz NR1508: 5.2 with internal amplifier.
        • Bi-Amp: Denon AVR-X6500H is able to bi-amp up to 5 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-X6500H supports Dolby Atmos.

        • Dolby Surround Upmixer: Denon AVR-X6500H 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

        Denon AVR-X6500H supports DTS:X.

        • DTS Neural:X: Denon AVR-X6500H supports 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-X6500H 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: Denon AVR-X6500H 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.

        Auro-3D

        Denon AVR-X6500H supports Auro-3D.

        • Auro-Matic upmixer: Auro-Matic upmixer takes non Auro-3D sound and upmixes to the current speaker configuration.

        IMAX Enhanced

        Denon AVR-X6500H is IMAX Enhanced certified. To qualify for IMAX Enhanced certification, 4K HDR televisions, projectors, sound bars, a/v receivers, loudspeakers, powered subwoofers and other premium home entertainment devices must meet carefully prescribed performance requirements established by IMAX, DTS and Hollywood's leading experts.

        • What makes an IMAX Enhanced A/V receiver different from an A/V receiver with DTS:X technology? DTS:X technology is commonly found in most multi-channel A/V receivers on the market today. All IMAX Enhanced A/V receivers include DTS:X technology and deliver additional features, such as auto-sensing of IMAX Enhanced content, via IMAX Mode. IMAX Mode indicates that your A/V receiver supports fully immersive IMAX signature sound.

        9. HDMI

        Denon AVR-X6500H comes with 8 HDMI inputs. It has 3 outputs - 2 for MAIN and 1 for ZONE2.

        Marantz NR1508 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 Denon AVR-X6500H: It can upscale up to 4K 50/60Hz 4:4:4 from HDMI and analog sources.
        • Analog To HDMI Upconversion: Denon AVR-X6500H 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)

        Denon AVR-X6500H 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.


        Gaming Features

        Denon AVR-X6500H supports Auto Low Latency Mode (ALLM) for lag-free and smooth gaming.
