In order to use this feature speakers must have 2 pairs of connectors.

      8. Immersive Audio Formats

      Dolby Atmos

      NAD T 778 and NAD T 758 V3i 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

      NAD T 778 and NAD T 758 V3i 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 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

      NAD T 778 comes with 6 HDMI inputs. It has 2 outputs which work parallelly and output the same signal.

      NAD T 758 V3i comes with 3 HDMI inputs. It has 1 output.

      • 4K/60Hz Passthrough on NAD T 778: All inputs pass up to 4K 50/60Hz 4:4:4 video signal.
        8K/60Hz and 4K/120Hz Passthrough on NAD T 758 V3i: All inputs pass up to 4K 50/60Hz 4:4:4 video signal.
      • 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 NAD T 778 only).
      • 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)

      NAD T 778 supports HDR10, Dolby Vision and Hybrid Log-Gamma.

      NAD T 758 V3i supports HDR10 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)

      NAD T 778 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.

      10. Inputs and Outputs

      Audio

      • Phono Input: There is an MM phono input on NAD T 778 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
      • Analog Pre-Outs: NAD T 778 has 11.2 and NAD T 758 V3i has 11.1 preamplifier outputs which allow you to connect the receivers to the external power amplifiers. 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, NAD T 778 has 11 channel processing but has only 9 channel amplifier, so it needs external amplifier connected to the analog pre-outs in order to reach its maximum speaker configuration.
      • Analog Line Inputs: There are 2 pair of line inputs on NAD T 778 and 4 pair of line inputs on NAD T 758 V3i for connecting sources with analog outputs.
      • Digital Inputs: 2 optical inputs and 2 coaxial inputs 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.
