• Timecode is required for real-time Loudness measurement in the Dolby Atmos Renderer, and will use 1 audio channel.
• The Dolby Atmos authoring process can be quite CPU intensive, depending on the size of your project.
  Therefore, Merging recommends running Pyramix Native on i7 CPU (or more) with 16 Gb of RAM (or more).

• Dolby Atmos Renderer on Windows: the Dolby Atmos Renderer requires MAD to be configured with a buffer size of 512 samples.  ThereforeTherefore, it cannot be used in AES67 mode (for connectivity with DANTE devices, i.e.) since AES67 requires MAD to be set with buffers sizes which are multiples of 48 (48, 96, 192 or 384 samples).
  If the Dolby Atmos Renderer is hosted on a Mac computer, there is no such limitation.

• Recording back Live Re-renders on the Pyramix computer is possible.  The number of channels may vary depending on your computer and project configuration.
  Exporting Re-renders offline from the Dolby Atmos Renderer application is possible when opening the Dolby Atmos ADM Master file (Export Audio > Re-Renders).
• MacMini 10Gb Ethernet port : currently not suitable for RAVENNA/AES67 network.   Please use a dedicated USB-C to Ethernet, USB3 to Ethernet, or Thunderbolt to Gigabit Ethernet (Sonnettech) adapter.
• Currently Pyramix can only export 48kHz Dolby Atmos ADM Master files.

Configure the AES67/RAVENNA Network

All the devices have to communicate in the same RAVENNA (64) or AES67 (48) mode.
If you use DANTE devices (MacOS only), you must set the network in AES67 mode (48).
If you use Merging devices, you can set the network in AES67 (48) or RAVENNA (64) mode.

• Pyramix - Merging Audio Device
  Please open the MAD Panel, and click on Advanced settings :
  Set MAD in RAV/AES67 mode
  Set Merging Audio Device as Master ASIO Host
  Set the sampling rate to 48000
  Set the Buffer size to 512
  Set the Sample type to 32bit integer
  Set the required Number of Inputs and outputs:
  Up to 128 Inputs and outputs, but unused channels will still use some power processing. 
  Therefore Merging recommends you rather set the number of channels you need ; e.g. if you don't plan to use Live Re-renders, 8 inputs are sufficient.
  Merging recommends you disable the MAD - WDM, or do not set the WDM outputs to any Bridge channels, to avoid having the WDM channels routed into the Dolby Atmos Renderer.
  Set the Latency to 6/12/48 AES67 (mandatory for DANTE devices) or 16/32/64 (RAVENNA).
  Click on Apply
  
  
• Hapi MKII
  Browse to Setup > System, and set the Latency to AES67 48smp (mandatory for DANTE devices) or Low 64 smp (RAVENNA).
• Anubis
  Browse to Home (Merging logo button) > Settings > General, and set the Latency to AES67-48 (mandatory for DANTE devices) or Low-64 (RAVENNA).
  DANTE devices
  Your DANTE devices must be set to AES67 mode.  Please consult your DANTE device documentation for details.

Configure the Dolby Atmos Renderer audio driver

...

• In the World view (left pane), select both Anubis and your Hapi MKII.
• In the Matrix (right pane), connect the relevant Anubis Monitor to the Hapi MKII.
  Note: Make sure you first select the Monitor set on the Anubis itself in order to see it listed for connectivity in ANEMAN
  
• The Binaural Source can be listened to by selecting the Stereo Monitor (named "Phone" in our example), then the Stereo Source (named "Binaural" in our example), directly on the Anubis.
