There are two main types of DAC firmware.
One is firmware related to USB connection, which rewrites the control program in the XMOS chip. This update of Ver1.08 is an update of this part, and users can do it using a PC.
The other is the firmware of the controller called MCU. The MCU is a small one-chip PC and is in charge of controlling the DAC.
A special tool is required to update this firmware, and it must be returned to the factory. Unfortunately, the user cannot update this firmware.
