These are instructions for updating the firmware in both your DAC and Digital Director.

*** Attention Digital Director owners***

To start, if you have not installed your digital director in your system, first begin by updating the DAC firmware. This is important, your DAC will not recognize the Digital Director and the firmware updates will not work. Your Discrete DAC firmware must be updated to 21.14 or later. Please check your DAC firmware before installing your Digital Director. This can be done by scrolling through your DACs menu until you see the “Code” or “DAC Software” screen where the currently installed revision number will be displayed.

Begin by downloading both the Digital Director Firmware and the DAC firmware.  Add these files to your bit perfect playback software.  Please note, these must be played by a bit perfect source, if the update fails, it is not being played bit perfect. These updates includes two upgrades within the same file. The file is several minutes long. Please do not interrupt the process and let the file finish to the end. When you play the file you will hear instructions and two upgrade tones. Following each tone you will either hear silence for about 30 seconds (this varies) or you will hear the message ‘upgrade failed’. If all the upgrades fail, it is because you did not play the file bit-perfect. You may have computer upsampling on or digital volume control somewhere in your playback system. The screen on the DAC will confirm when the upgrade is happening. Contact MSB if you need help.

After the DAC firmware is updated, you can now install your Digital Director.  Please see our other video on Digital Director Setup for more specific instructions.

For any updates after the initial setup, you will need to follow this order for updating.

Power on the DAC and the director. Always begin by updating the DAC firmware first.  The Firmware file will not be able to update the DAC while Digital Director processing is on.  Enter the menu, scroll to the “Director” screen, then select “passthrough mode” for the Digital Director.  This will allow the firmware update to reach the DAC bit perfect.

Now, play the DAC firmware update.  After the DAC firmware is installed and complete, you can now play the Digital Director firmware.  Finally, go back into the menu and enable the Digital Director filtering again.

After the firmware updates are complete, you can check for a successful connection between the Digital Director and DAC indicated by a small “+” sign on the display.  If you do not see this “+” sign, the Digital Director is not performing the improved digital filtering.  Please check the menu to see if the filtering is enabled.  If it is, please check and confirm the currently installed firmware numbers reflect the new update files.

If you see an error message with “Err” it means there is an issue with the quality of the ProISL connection or tousling control cable. Check your cables and replace.

If you need further clarification or are encountering issues with your update, please reach out to our technical support team.
