        7. Speaker Configurations

        Denon AVR-X1800H DAB's and Yamaha RX-A840's amplifiers can be assigned for different speaker configurations.

        • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
        • Denon AVR-X1800H DAB: 5.2.2 with internal amplifier.
        • Yamaha RX-A840: Not supported.
        • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
        • Denon AVR-X1800H DAB: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.
        • Yamaha RX-A840: Not supported.
        • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
        • Denon AVR-X1800H DAB: 5.2, 7.2 with internal amplifier.
        • Yamaha RX-A840: 5.2, 7.2 with internal amplifier.
        • 2-ch Bi-Amp: Both models are 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-X1800H DAB supports Dolby Atmos.

        • Dolby Surround Upmixer: Denon AVR-X1800H 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-X1800H 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-X1800H DAB supports DTS:X.

        • DTS Neural:X: Denon AVR-X1800H 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-X1800H 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-X1800H 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

        Denon AVR-X1800H DAB comes with 3 HDMI 2.1 inputs with 8K support and 3 inputs with 4K support. It has 1 output.

        Yamaha RX-A840 comes with 8 HDMI inputs. It has 2 outputs which work parallelly and output the same signal.

        • 8K/60Hz and 4K/120Hz Passthrough on Denon AVR-X1800H DAB: 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.
          4K/60Hz Passthrough on Yamaha RX-A840: All inputs pass up to 4K/60p (YCbCr 4:4:4) video signal.
        • 8K Upscaling on Denon AVR-X1800H DAB: It can upscale up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 from HDMI sources.
          4K Upscaling on Yamaha RX-A840: It can upscale up to 4K/60p (YCbCr 4:4:4) from HDMI and analog sources.
        • Analog To HDMI Upconversion: Yamaha RX-A840 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 Denon AVR-X1800H DAB only).
        • HDCP Copy Protection: Denon AVR-X1800H DAB is HDCP 2.3 and Yamaha RX-A840 is 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-X1800H DAB supports HDR10, HDR10+, Dolby Vision, Dynamic HDR and Hybrid Log-Gamma.

        Yamaha RX-A840 does not support HDR. 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-X1800H DAB 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-X1800H DAB supports Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.

        10. Inputs and Outputs

        Audio

        • Phono Input: There is an MM phono input on Denon AVR-X1800H DAB with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
        • Analog Pre-Outs: Yamaha RX-A840 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 and Outputs: There are 2 pair of line inputs on Denon AVR-X1800H DAB and 5 pair of line inputs on Yamaha RX-A840 for connecting sources with analog outputs. There is also 1 pair of line outputs on Yamaha RX-A840.
        • Digital Inputs: 2 optical inputs and 1 coaxial input are available on Denon AVR-X1800H DAB and 2 optical inputs and 2 coaxial inputs are available on Yamaha RX-A840 for digital audio connections.
        • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
