        Denon AVR-X1700H DAB's and Denon AVC-S660H's amplifiers can be assigned for different speaker configurations.

        • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
        • Denon AVR-X1700H DAB: 5.2.2 with internal amplifier.
        • Denon AVC-S660H: Not supported.
        • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
        • Denon AVR-X1700H DAB: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.
        • Denon AVC-S660H: Not supported.
        • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
        • Denon AVR-X1700H DAB: 5.2, 7.2 with internal amplifier.
        • Denon AVC-S660H: 5.2 with internal amplifier.
        • Bi-Amp: Denon AVR-X1700H DAB 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-X1700H DAB supports Dolby Atmos.

        • Dolby Surround Upmixer: Denon AVR-X1700H DAB 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.
        • Dolby Atmos Height Virtualization: Denon AVR-X1700H DAB supports Dolby Atmos Height Virtualization which is a digital signal processing solution that leverages Dolby's deep understanding of human audio perception to create the sensation of overhead sound from the listener-level speakers.

        DTS:X

        Denon AVR-X1700H DAB supports DTS:X.

        • DTS Neural:X: Denon AVR-X1700H DAB 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-X1700H DAB 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-X1700H DAB 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.

        9. HDMI 2.1

        Denon AVR-X1700H DAB and Denon AVC-S660H come with 3 HDMI 2.1 inputs with 8K support and 3 inputs with 4K support. It has 1 output.

        • 8K/60Hz and 4K/120Hz Passthrough: On both receivers 3 out of 6 inputs pass up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 and the rest of the inputs pass up to 4K 50/60Hz 4:4:4 video signal.
        • 8K Upscaling: Both receivers can upscale from 1080p up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 from HDMI sources.
        • 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 2.3 Copy Protection: Both receivers are HDCP 2.3 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, HDR10+, Dolby Vision, Dynamic HDR 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-X1700H DAB and Denon AVC-S660H support 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

        Both receivers support Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.
