7. Firmware Update 
The ADI-2 DAC might receive improved features or bug fixes by a firmware update. This update 
will be available from the RME website, section Downloads, USB. Download the tool that 
matches your operating system (Mac or Windows), then unpack the zipped archive. 
The Flash Update Tool updates the firmware of the ADI-2 DAC to the latest version. Under 
Windows it requires an already installed MADIface series driver, which is found on the same 
download page. 
Start the Flash Update Tool. It displays 
the current revision of the ADI-2 DAC 
firmware, and whether it needs an 
update or not. If so, then simply press 
the 'Update' button. A progress bar will 
indicate when the flash process is 
finished (Verify Ok). 
After the update the ADI-2 DAC needs 
to be reset. Push the standby button to 
switch it off for 5 seconds. 
When the update unexpectedly fails 
(status: failure), the unit's Safety BIOS 
will be used from the next boot on, the 
unit stays fully functional. The flash 
process should then be tried again. 
The flash process does not affect user 
data like sample rate choices, EQ 
settings or Setups. 
Returning to Factory State 
In case a total reset is desired: hold encoder 1 and the VOL button pushed while turning on the 
unit. This will reset all current settings to factory default. User-stored Setups and EQ presets are 
not affected. The same action is performed by loading Factory via Setup Select. Note that the 
reset will be incomplete when the unit is connected to USB while performing the reset. 
When holding encoder 1, 2 and the VOL button pushed while turning on the unit, user-stored 
Setups and EQ presets are still not affected, but their names are reset as well.
