Prepare to Update

  3. Insert the SD card with the .prg file.
  4. Power on the MixPre.
  5. Navigate to System > Update Firmware and follow the on-screen instructions.
  6. When the update is complete the recorder will power cycle itself. The version number MixPre_ 4.01 will be displayed briefly on the splash screen while booting up. A message box appears “Firmware updated successfully Version: MixPre_ 4.01”. Tap “OK”. Please note any changes or additions to the main Menu (if applicable). Consult product documentation for details.
