About Auro-3D

By fully immersing the listener in a cocoon of life-like sound, Auro-3D® creates the sensation of actually ‘being there’. Thanks to a unique configuration of ‘Height channels’, acoustic reflections are generated and heard naturally due to the fact that sounds originate from around as well as above the listener. Either 1 or 2 additional layers (HEIGHT and TOP – a.k.a. “Voice of God” channel) with speakers are mounted above the existing Surround layer at ear-level to produce Auro-3D®’s defining ‘vertical Stereo field’.


The height information, captured in recording or created during the mixing process, is mixed into a standard 5.1 PCM stream that comes with a regular Blu-ray. Moreover, the Auro-3D Engine combines different technologies to guarantee an optimum 3D sound experience generated both natively and from existing audio content. It recognizes Mono, Stereo, 5.1 Surround or an Auro-encoded signal and transforms them into 3D audio. Regardless of original format, you can always experience the stunning effect of sound in 3D.

​Upgrade Preparation

Please ensure the following is ready before registering your device:

    This is easy to test by simply selecting an Internet radio station and ensuring that it is correctly output by the Marantz unit. Please see the corresponding pages in your Operating Manual for this.
  2. Before upgrading, please update your Marantz product to the latest firmware version via the Internet. You can find information on how to do this in your Operating Manual.
  3. Find out the Upgrade ID of your Marantz product. To get your Upgrade ID, call up the A/V pre-amp/receiver menu and select "GENERAL“ - "FIRMWARE“ - "ADD NEW FEATURE“.

    or an “S” in place of a “5”,
    or a “Z” in place of a “2”,
    or a “U” in place of a “V”,
    or “I” in place of a ”1” or a “7”,
    or an “E” in place of a “F”.
