Select DAC II Firmware
When do I need a Firmware update?
DAC firmware updates offer both corrections of problems we found and performance improvements. We recommend keeping your DAC Firmware up to date. You can check the current version of Firmware installed by following these steps:
- Press the menu button on the top of the unit (left button with square on it)
- Turn the volume knob until “DAC Software” is displayed
- You will see code revision number
- The current version is 188.8.131.52
What to expect when doing the firmware update
This update 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.
What has changed in this version?
Version 184.108.40.206 has made improvements in the overall sound quality for all sample rates. It also provides optimal support for the MQA USB module. It is necessary to upgrade to this version if you have upgraded your USB module to the MQA version.
