• For best results in the DCiDA amplifier both the HiQnet Audio Architect DCiG host firmware and the Dante firmware must be updated to the versions above. 

Prerequisites:

• Audio Architect v2.55.3 or higher
• Dante Controller v4.17.1.1 or higher

Programming Information:

• Install DCiG firmware using Audio Architect. 
  If the firmware version is not already available in Audio Architect, it may be added by copying the BND file to C:\Program Files\Harman Pro\Audio Architect <version>\FirmwareUpdates, for example C:\Program Files\Harman Pro\Audio Architect 2.55\FirmwareUpdates . 
  Audio Architect must be restarted if it was open when the file was added

Dante Firmware Previous Releases

Changes in Crown v1.19.0/Dante 4.2.3.13 (August 9, 2023):

• Added additional support for Dante Domain Manager, Dante Director, bug fixes and support for new hardware changes. 
• Telnet is disabled.
• Reboot from Dante Controller is disabled.
• When clearing config, Keep Network Configuration cannot be unchecked.

Changes in Crown v1.12.0/Dante 4.0.7.8 (September 17, 2019):

• Dante Device ID is corrected. DCiDA amps will no longer accept Sound London Dante firmware when Dante Updater isn't in Manufacturer Override mode. 
• Dante Connection status now updates correctly in Audio Architect. 
   

Known Issues:

• If multiple amplifiers have the same Dante hostname on the network, for example DCiDA, then only one will be recognized in Dante Controller. 
  Workaround: connect only one amp at a time and be sure to give it a unique hostname (aka device name) before connecting another. 
• Some settings in Dante Controller may revert after a few seconds, for example, changing the device name or AES67 Enabled setting. 
  Workaround: Try again. Be sure to wait 15-20 seconds before leaving the tab and changing anything else. 
• There are two separate files for DCiDA Dante firmware.  One for DCi4x1250DA/DCi8x600DA, and one for DCi4x600DA/DCI4x300DA/DCi8x300DA.  The only difference in the two files is the order of the Dante Primary and Secondary ports. 
  • The correct versions of both DNT files were initially included with Audio Architect 2.25.1, build date 9/17/2019.
  • The DCi4x600DA/DCI4x300DA/DCi8x300DA DNT files included with Audio Architect v2.45.0 and v2.45.1 were incorrect and would swap the Dante Primary and Secondary ports.
  • The DCi4x600DA/DCI4x300DA/DCi8x300DA DNT files included with Audio Architect v2.45.2 and higher are correct and do not have the port swap problem.
• DCiDA amplifiers with earlier versions of Harman International/Dante firmware must be updated to Crown/Dante firmware by putting Dante Updater into Manufacturer Override mode.
