Configure the AES67/RAVENNA Network

The 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
    Open the VS3 Control panel, and set the Latency to - 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, 16 (up to 9.1.4 + Binaural) or 24 outputs 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 Low Latency 16/32/64 (RAVENNA).
    Core assignation : The Dolby Atmos authoring process can be quite CPU intensive, depending on the size of your project, for both MassCore assigned Cores, and also for the Windows ones.
    Merging recommends you assign at least as much cores to Windows as to MassCore.

  • 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.
