Your NADAC+PLAYER comes with a VIP Service Program that covers software and firmware issues that are not covered by the general warranty terms, but may require reconfiguring the unit at Merging Technologies factory in Switzerland.

However, to avoid unnecessary shipping of the unit and its potentially long immobilization, NADAC+PLAYER includes a recovery mechanism for its internal CPU operating system, drivers and applications.

 

Warning
Important note 1: This recovery procedure is only applicable to NADAC PLAYER running ROON OS version 1.0.148 and above.
If your NADAC PLAYER has not been updated to ROON OS 1.0.148 or above, please download the previous Recovery procedure. 
Warning
Important note 2: Please do NOT proceed to a system recovery before contacting Merging Tech support to find alternative solutions first.

 

The procedure for performing a complete recovery of the NADAC+PLAYER internal CPU is described below:

 

Panel
  • Backup your Roon database before proceeding as it will be deleted by the recovery mechanism.
    Backing up the Roon database is available through the Roon Remote menu Settings > Backups.
    This procedure is required only if you performed any metadata editing on your library. If not, the library will be automatically reconstructed when you connect your music files at the end of the recovery process.
  • Your computer device has to be connected to the same network as your NADAC+PLAYER (e.g. the device you use to remote control Roon)
    In your web browser , access the NADAC+PLAYER System Status page.
    Type  http://nadacplayer-<<your nadac serial number>>.local
    Example with serial number 100227 :
  • The System Status page will open.
  • First try to restart the Roon Server Software, by clicking the Restart button next to Roon Server Software, and confirm.
    During the restart, the front panel display will briefly show a red blinking stop sign on the top right of the display under the sampling rate.
    Restarting the Roon Server Software should only take a few seconds.
  • If after the restart, you still cannot use your NADAC+PLAYER, access the System Status page as described above.
    Press on the Reinstall button next to Operating System.
  • Warning:  During the re-installation process, the front panel display will show a red blinking stop sign on the top right of the display under the sampling rate for several minutes.

    Wait until this blinking red sign turns back to a steady white logo.
    The source display (NADACPLAYER-XYZ) on the bottom of the display should also turn to white at this stage. This means the recovery procedure is completed.
  • Launch your Roon Remote application on your tablet, smartphone or computer and connect to your NADAC+PLAYER.
  • You will now have to re-enter your account information: email address and password.
    If this procedure fails with an error saying Network problems, it probably means that the Roon Core is performing some updates, please wait for 5 to 10 minutes and try signing in again.
  • Go in the Settings > About (on the top right corner of the Settings page) and proceed to any updates the system may suggest.
    This may involve a few reboot of the Roon Core but will not require rebooting the whole NADAC+PLAYER.
  • Go in the Roon Settings > Audio, locate the Roon Ready section and locate the Merging Technologies NADACPLAYER audio unit.
    Click on the button Enable and give it a name, like “My NADAC” or NADAC-XYZ. Initial factory programming names it NADAC-XYZ where XYZ is the three last digit of the unit's serial number.
    You can go to the settings pages for that audio unit and configure further options for your NADAC driver, like multichannel behaviors, etc...
  • Exit the settings page and select your NADAC audio unit as your current Zone on the bottom bar of the Roon user interface.
  • Reconnect to your music files through the Settings > Storage page.
  • Restore your Roon database if you backed it up initially.
