Also, forgive my ignorance, but what do you mean by "switching between monitors and headphones"? Can you only have signal to one or the other at a given time?
Lets start simple:
Usually you connect active speakers (aka "monitors") and phones to the main recording interface with TM FX mixer sw.
You open TotalMix FX and create your usual setup/routing:
1st configure TM FX control room, so that the control room features as "mono, dim, etc" become available for your main outputs:
1. assign Main Out to e.g. Analog Out 1/2
2. assign Phones1 to e.g. Analog Out x/y (depends on the interface)
Then you configure the routing for Monitors, save it to snapshot 1.
Then you configure the routing for Phones1, save it to snapshot 2.
If you want to hear music through monitors, open TM FX, recall snapshot 1.
If you want to hear music through phones, open TM FX, recall snapshot 2.
You can even configure TM FX to restore only the routing, but not the volume level (all nice and flexible).
But now imagine, you do not want to open TM FX all the time to control routing.
Therefore you buy e.g. the ARC USB. It can be used by all RME interfaces that support TM FX (as good as all back to ~2001, thanks RME ! Even for interfaces for which no remote was ever planned.)
Then you can select Snapshot 1 and 2 by pressing a key on the ARC USB ... so nice so far.
But as I said, either the volume becomes restored as it had been saved or you configure in preferences not to restore volume, then it stays like it is. Whenever you switch, you usually directly restore the volume.
Now you connect an ADI-2 Pro to the system, e.g. through ADAT1 to have a digital/lossless connection.
Clock master = recording interface (setting clock source = internal, ADI-2 Pro: clock source SPDIF)
Monitors and Phones also move to the ADI-2 Pro.
Now you have only one connection to the ADI-2 Pro through one digital port.
Now you can use the remap-key feature of the ADI-2 Pro to switch between monitors and phones by e.g. making a short click to the I/O key. Like described in this article: https://www.tonstudio-forum.de/blog/ind … our-Setup/
The advantage here is, the ADI-2 pro FS has built-in relais, that perform a slow ramp-up of volume within approx 1sec.
This has been done so that nobody gets ear problems, because the extreme power outputs have so much power, that it could severely damage either phones or additionally also your ears.
And the handling is very nice, whenever you switch on the ADI-2 Pro, then you always have this nice ramp-up in volume.
This setup is currently my personal favourite. Switching on the ADI-2 Pro
And then on the recording interface (UFX+) routing to other systems, or for special recording use cases / purposes.
Another option which I highlighted 1st in this article https://www.tonstudio-forum.de/blog/ind … ort-DE-EN/
is how you can route audio with the ARC USB by connecting the ADI-2 Pro with two different digital links to the recording interface.
Then in the ADI-2 Pro's "AD/DA" Basic routing mode you can configure, that
- Main out gets audio from AES
- Phones 3/4 gets audio from ADAT ("SPDIF")
Then its even possible to route audio to either monitors or phones by routing with TM FX and also with the ARC.
Simply send audio to AES, then you hear it in monitors or to ADAT then you hear it through phones.
But then you have no ramp-up of volume because
- there is nothing being switched at the ADI-2 and
- also nothing that triggers the relais by plugging phones ...
So these are the different possibilities ...
And I like the RayDAT because it has it all .. many types of digital connections.
And even if you would use all 4 ADAT ports to connect even preamps or converts,
you would still have one SPDIF and one AES port free to be hooked up to the ADI, to be able to switch with TM FX / ARC.
And .. whenever you WOULD require it, you can also add a Word Clock module.
And if you want to play MIDI notes and render audio through your synth ... well this is also possible, because RayDAT also has MIDI ..
Well because of this flexibility I like the RayDAT more compared to Digiface USB.
But that doesn't mean that Digiface USB is bad ...
You only need to know whats "sufficient" for you.
The problem at the beginning for everybody is to exactly know "whats sufficient".
Therefore I am a big fan of pragmatic solutions ... UFX+ ... end of discussions .. you are in dreamland.
And you have USB3/2 and Thunderbolt
So also towards the PC or Apple you have lots of options.
And the best interface for standalone mode. Amen
A solid basement for everything and based on the latest analog designs of RME for recording interfaces.
In other words, the combination of UFX+ and ADI-2 Pro (now or later) is a no-brainer, you can do everything with it.
Very long investment protection. You do not need to worry about anything that you "might have forgotten".
Can use it also very flexible in a mobile recording environment. Record with DURec like with a tape deck or as backup recording.
