      7. Immersive Audio Formats

      Dolby Atmos

      Yamaha Aventage RX-A770 supports Dolby Atmos with Surround Upmixer.

      • 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

      Yamaha Aventage RX-A770 supports DTS:X with Neural:X.

      • Neural:X 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 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.

      8. HDMI

      Yamaha Aventage RX-A770 features 6 HDMI inputs. It has 1 output.

      • 4K/60Hz Passthrough: All inputs pass up to 4K/60p 4:4:4 video signal.
      • 4K Upscaling: Yamaha Aventage RX-A770 can upscale up to 4K 60p 4:4:4 from HDMI and analog sources.
      • Analog To HDMI Upconversion: The a/v receiver supports video upconversion, so you can connect your analog Component and Composite video sources and Yamaha Aventage RX-A770 will output them 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%.
      • HDCP 2.3 Copy Protection: All inputs and outputs are HDCP 2.3 compliant which is a requirement for 4K/HDR copy-protected content transmission.
      • 3D Ready: Yamaha Aventage RX-A770 is able to pass 3D video through HDMI.

      HDR (High Dynamic Range)

      Yamaha Aventage RX-A770 supports HDR (high dynamic range) video formats such as HDR10, Dolby Vision and Hybrid Log-Gamma via HDMI ports. 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)

      Audio Return Channel (ARC) feature 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.
