Hi Vicshere,

welcome to the RME user forum.

I never heard of any incompatibilities regarding ADAT in general, so it will work.

The UFX II is an excellent and feature rich recording interface, a solid basement for your setup, good choice.

I do not know how to answer your second question in terms of "whether its a good match".

To be able to judge this from different angles I would need to know more about your current and future demands regarding:
- number of I/O ports that you actually need, its always good to have reserves for future demands
- whether you might need to add additional devices like additional preamps or AD/DA converter in the future
- whether you intend to record at double speed (88.2/96 kHz) which reduces the number of ADAT channels by 50%

Regarding the UFX II (vs UFX III)

For the UFX II, I can definitive tell you that you did a good choice. The only question that you should always raise from the perspective of a long-term investment is, whether it would be better to buy the UFX III with MADI (64 additional channels) instead, this is only around €550 more (+26%), but you have more options for the future. Selling UFX II and having to buy UFX III at a later point would mean more loss of money and things are not becoming cheaper these days.

Don't worry quality wise, both interfaces UFX II and III are basically the same, the only difference is MADI and USB3 because of higher channel count.

But as I mentioned above. Always think about the future. One of the most important questions is, whether you might want to record in double speed (88.2/96 kHz) or not. I am currently satisfied with 44.1 for the things that I currently do.
But I do not know your demand.

If you can't exclude that you want to record at double speed in the future, then an UFX II might become too small quickly.

Lets assume that you want to record in double speed and you have the Neve connected to ADAT1.
Then you have only ADAT2 free for connecting another device like e.g. an 8 port preamp.
At double speed you have only 4 instead of 8 channels due to channel multiplexing.
This means at double speed you can only use 50% of the ports of the 8-port preamp connected to ADAT2.

In such a case it would be better to have MADI to be able to add more external 8- or 12- port devices. MADI has at single speed 64ch, at double speed still 32 channels to definitively support adding more devices, where you can also chain multiple in a serial fashion. Then you could use those two ADAT ports for connecting such smaller devices like the Neve preamp.

Regarding the Neve

The Neve I don't know. Also not your expectations, I assume something like "Neve Sound".
Whether this device really has the Neve Console or Preamp sound .. I don't know.

I see that the Neve only supports USB3 bus power and that it doesn't seem to support stand-alone operation mode.
The manual says that the driver setting dialog shows a selection for clock synch via ADAT, if ADAT is connected.
So you might need to install the Neve driver for operation of the device even if you do not need it for the application.

Clock synchronization

I would use the UFX II as clock master in this setup (set clock source = internal in MADIface driver settings)
and the Neve will be slaved to the clock of the UFX II, clock source ADAT IN.

I am not sure whether of interest for you, but as it is fresh. If you want to document your setup, maybe you have interest reading my latest blog article, which gives you an Excel template file for documenting a setup:

Yes, it’s tricky! Thank you.
