Hi Damascato,

see this sticky article for an overview of the ADI-2 DAC / Pro devices in order of appearance and their differences:
https://forum.rme-audio.de/viewtopic.ph … 06#p165706

If you are not yet familiar with the operation of your new device, here is how to find this out, e.g. for "Main Out 1/2":
I/O -> Main Out 1/2 -> Settings -> DA Filter -> SD LD

Hint: while you are at it, you can check the current filter settings for all ports by turning Encoder 1 "B".

More verbose instructions:
  Press Button I/O
  Turn Encoder 1 "B" until you see "Main Output 1/2" in the 1st line of the display (green background)
  Turn Encoder 2 "T" until you see "Settings" in the 2nd line of the display (grey background)
  Push Encoder 2 to scroll down on this menue page until you are on the entry "D/A Filter"
  [ push Encoder 1 to scroll up, if you missed the enty ]
  At the entry "D/A" Filter turn Encoder 2 clock-wise to the last entry which should be "SD LD".

For more information about the D/A filter "SD LD", see manual p. 83.
