Please follow this procedure if you already have the Merging Ravenna ASIO driver installed and want to update to Merging Audio Device driver.


System Requirements

Certified Windows Operating Systems (OS)

The Merging Audio Device Driver has been tested and qualified on Windows 10 Professional 64 bit.

Which Windows operating system am I running ?

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

The Merging Audio Device - WDM bridge is not compatible with Windows 7.  
If your computer is running Windows 7, please continue using the Merging+NADAC ASIO driver
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) 
  • MERGING+NADAC will follow the sampling rate changes provided by the ASIO host.
    If several ASIO hosts are present, the Master ASIO Host will determine the sampling rate.

Additional notes on the Merging Audio Device panel


Status section

Sample Rate: Shows the current Driver Sampling Rate

State: Shows the connected ASIO Host or warn user if no ASIO Host is connected.

Network Configuration section

Your MERGING+NADAC will appear in the online devices when properly connected.

Mouse clicking on the MERGING+NADAC icon will open the MERGING+NADAC app which allows some remote control functions

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.

Clicking on the NADAC icon will give you the status error at cause

Example: Not Reachable.

Verify your set up connections and reboot your MERGING+NADAC
