How-to configure MERGING+NADAC with Roon on Windows OS ?

Merging Audio Device driver users :
Merging recommends you set your Main Media Player as Master ASIO Host in the Merging Audio Device panel, to avoid untimely sampling rate changes from other players.

If you want to run at a fixed sampling rate, then please set Merging Audio Device as your Master ASIO Host.  In such case you may need to configure your Media Player to convert to the set sampling rate.
When your MERGING+ device is in DSD sampling rate, the driver mixing features are disabled, and the WDM audio is not available.

Prerequisite

The MERGING+NADAC ASIO driver (Win7 / Win10) or the Merging Audio Device driver (Win10) is installed and configured
Roon media player is installed https://roonlabs.com/

  1. Start ROON player

  2. Click in the top left corner Menu and select Settings menu.

  3. Go to the Audio Menu
    Merging RAVENNA ASIO driver users :     select MERGING RAVENNA ASIO Driver and click on Enable.
    Merging Audio Device driver users :     select Merging Audio Device driver -ASIOand click onEnable. Do not select the WASAPI version
  4. Enter a Zone Name for the MERGING Ravenna ASIO driver device /Merging Audio Device driver.

    Click on the Settings  icon next to the Zone Name and select Device Setup.

  5. In the General tab :
    Set the Volume Control Mode to Use NADAC Volume Control (this feature requires Roon 1.2 or above)
    Set the Resync delay to 0.1s


  6. Now in the Advanced section :
    Set the Max Sample Rate (PCM) to 384kHz
    Set the Max Bits per Sample (PCM) to 24.
    Set the Max Sample Rate (DSD) to Up to DSD256.
    Channel Layout should be set according to your NADAC model; 2.0 if you have a 2 Channels NADAC or 7.1 if you have a 8 Channels NADAC.
    Configure the Multichannel Mixing Strategy according to your needs  (see this page for details)
    Click on Save Settings.
     

  7. You can now play music on your MERGING+NADAC.
    If you have several Zones defined, make sure you have selected the NADAC one.
    You may control NADAC volume directly from Roon, with its Speaker icon in the bottom right corner.

     


    Note on Volume Leveling and Crossfade options

    Both Crossfade and Volume Leveling options in the Zone Settings page enables a sampling rate conversion for DSD files, which will prevent NADAC to run in DSD native mode, the conversion will force the device to run in DXD mode. Disable the Volume Leveling and leave the Crossfade option to 0 seconds if you don't want this conversion.
     
     

    DSP ENGINE

    Please use Roon DSP Engine features with caution, it can be very demanding resources wise, and therefore can cause drops for multichannels / high sampling rate playback !
