RME Fireface UCX II

Finally got my hands on my first RME product, UCX II !

The sound quality is superb, a noticeable difference from my lower-budget audio interface.

AD/DA conversion is the best I've experienced. The preamps are clean and have great headroom.

Drivers are strong, and some small errors I used to get in Pro Tools from the previous interface are totally gone with RME drivers (on Windows).

Overall I couldn't have been happier!
Time to dive into Total Mix and learn how to use DURec )))

It was worth waiting for it to be in stock for a while.
After ordering it, Thomann shipped it right away with no issues.
Thanks to RME and Thomann team!

The paper box containing this device is only about 40-50cm, about 15cm high and about 30cm wide.
But the wrapped package I think should contain a full-size computer case.
I thought I received something other than the RME UCX II.
But when opened, it's great. My package was well wrapped, to make sure it wasn't damaged in transit.

What's even better is that when I opened it up inside and got a free Thomann UK power cable, I was using it instead of the existing power cord, because it has a ground wire.

In terms of product, overall, this device is really great. The product has no scratches on the surface. So beautiful.

When plugged in, it works right away, and fast.

I still don't know how to use it properly.
But when you have just installed the company's driver, you will need to restart the machine, for TotalMix FX to be turned on. It looks harder to use on the inside than it looks on the outside.


It's difficult to buy an RME UCX II at the moment. Although it costs money, at least I feel I was lucky to have bought it, because I am an international customer. After a long time reading a lot of reviews and a decision has been made. But there was no stock, except for Thomann, and the product after I bought it was also out of stock. Perhaps anyone who wants to buy it later will have to wait for a relatively long time. I am very lucky and very satisfied with Thomann.

I am a UCX and Babyface PRO FS user.

This is a comparison between Babyface PRO FS and UCX II.

Owned equipment
Speaker Genelec 8331 (purchased at Thomann)
Headphones SHR1840

External processor
RUPERT NEVE DESIGNS Portico II Master Bus processor
SSL FUSION (purchased at Thomann)
Analog synthesizer

The first impression is the headphone amplifier.
Babyface pro fs sounds brighter than UCX II.
I hear more high frequencies.
The UCX II has the impression that it sounds a little more subdued than the Babyface pro fs.
If you like flashy sounds, Babyface pro fs is a good choice.
But UCX II is also very good. Enough for me.

Next is the impression of speaker out.
You can see the sound better with UCX II. Overall.

About input
I think the mic preamp, other inputs, and the UCX II are very good.

Both the UCX II and Babyface pro FS sound great.
UCX II is a very good item because I need a lot of input.

It's also worth noting that the major difference between UCX I and UCX II is the addition of AES.
I own a genelec 8331.
The difference in sound is obvious when connected to 8331 with AES.

If you are considering UCX II as a replacement from UCX I, I highly recommend UCX II. The UCX II has a good view sound.

**Edit 14/3/26**
I completely forgot to circle back to this initial review. Before giving up, I contacted RME once again, based on other favorable reviews. This time I received assistance from someone who was very knowledgeable and helpful. Once set on the right path, I can clearly recommend this product. It is a more expensive than alternatives, but it is so far ahead in features, performance and quality.

While I see this has great reviews which I am sure are legit, this interface was a big waste of time for me.

I did a lot of research, but apparently not enough. I had no idea that while a simpler inexpensive Focusrite can work seamlessly with most pieces of keyboard hardware, this RME is not enough to power a simple single synthesizer with monitors unless connected to a computer.

Secondly, while RME support was initially quite prompt in answering to issues involved in running necessary updates, they generally appeared to be noticeably unpolished and unhelpful. The update process is not necessarily correct on the RME website, and as many have mentioned on Youtube, tutorial and information videos are best referenced from individual users.
