The logic is different.
Basically the ADI-2 Pro chooses its operation mode automatically dependend on what you connect to the device.
The unit has different useful screens.
The main screen's purpuse is that you can choose the wanted volume and Bass/Treble.
The unit has special modes / routings, see handbook.
For some use cases it might be required to configure the unit for that purpose.
You can save up to 9 different configurations.
It's also possible to assign the 4 front knobs (VOL, I/O, EQ, SETUP) different functions.
Also to recall one of the 9 stored settings.
So if you have maybe 2 very different use cases you can map to two of the 4 mentioned keys
the function to i.e. restore setup 1 and 2.
By this you can make it very easy to your fam members to use the device.
If you hold the key longer than around half of a second, then the original function is being chosen.
But for most cases the unit does everything automaticall, i.e.:
- if you plug the phones to Phones 3/4 on the front, then the other analog output 1/2 is being muted and there is a slow rampup of volume so that you can remove phones from your head should it become too loud
- of you connect the unit per USB to a Laptop, then the unit automatically chooses USB operation mode.
All this is nicely explained in the handbook.
So basicallly its relatively irrelevant to see which signals come from where and are being routed to where.
This really nobody would understand.
For very nice troubleshooting of connections and where you have signals coming in and going out
the unit provides other main displays, which are very useful: see handbook chapter 15:
- Global Level Meter
- State Overview
The ADI-2 Pro FS or FS BE, if you like the black version more, is worth every cent.
I can strongly recommend it. Quality and feature wise the best product that you can get and for this price.
See Berndhards comment, that for him and hist customers the ADI-2 Pro FS even outperforms DACs in the price range of over $8500, see: https://www.forum.rme-audio.de/viewtopi … 93#p136193
