Updating Firmware
The following rmware instructions are for updating DAC and Digital
Director rmware. If you do not have a Digital Director installed in your
system, then ignore any Digital Director instructions. The rmware
les are .WAV audio les.
Updating DAC Firmware - Before Digital Director Install
To start, if you have not installed your digital director in your system,
rst begin by updating the DAC rmware. This is important; your DAC
will not recognize the Digital Director and the rmware updates will
not work. Your Discrete DAC rmware must be updated to 31.21 or
later. Please check your DAC rmware before installing your Digital
Director. This can be done by scrolling through your DAC’s 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
rmware. Add these les 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 include two upgrades
within the same le. The le is several minutes long. Please do not
interrupt the process and let the le nish to the end. When you play
the le, 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 le bit-perfect. You may have computer
upsampling on or digital volume control somewhere in your playback
system. The screen on the DAC will conrm when the upgrade is
happening. Contact MSB if you need help.
After the DAC rmware is updated, you can now install your Digital
Director. Please see our other video on Digital Director Setup for more
specic instructions.
Updating Firmware with a Digital Director
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 rmware rst. The Firmware le 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 rmware update to reach the DAC bit
perfect.
