RAVENNA/AES67 requires that the MERGING+NADAC is connected to a Gigabit Ethernet port.

The Merging Audio Device - WDM bridge is not compatible with Windows 7.
The ASIO driver is NOT supported under XP or Vista or any 32bit OS version. 

  • The Merging Audio Device driver supports up to 8fs (384 kHz, DXD or DSD64, DSD128 & DSD256)

Leaving your mouse over the MERGING+NADAC icon will give you the addressing details  

ASIO Settings section

Master ASIO Host : Allows to set a Master application, that will act as a Master sampling rate device.
This list is dynamically populated, the first time you start an application set to use the Merging Audio device, it will be added to the list.
When a Master ASIO host is set, other applications cannot change the sampling rate.
If left to Default, any application can change the sampling rate any time.
If set to Merging Audio Device, you can set the sampling rate from the panel, and ASIO applications cannot change it.
Some applications may not support such sampling rate change, refer to the manufacturer for details.
Changing the sampling while recording / playing back will obviously create drops, do not change the sampling rate during crucial real-time operations.

Audio and Video Sync

If you use the NADAC with MAD and listen to video it is important that you set the NADAC Playout setting to Pro mode in order to have the Video and Audio in sync.
Go to the NADAC System page and under Playout Delay select PRO mode.

Video and Audio should now properly be aligned. If you also use NADAC in parallel with Anubis then PRO mode is also recommended.
