I'm a technical science communicator, reliant on using Linux. Linux has very poor audio support, and so the thing I was most interested in with this device was being able to build a nice vocal channel for streaming, presentations, calls etc. that is not dependent on the computer.
As the device is class compliant, it works totally fine with Linux, you just don't have ability to configure the plugins. However, I can do that in Windows, save to a preset and then I can select which preset to use for my task while using Linux.
I have 3 presets I use the most:
1/- clean - nothing, using for recording videos that I will process later
2/- voice channel - gentle compression and limiting, eq and a bit of a boost
3/- extreme monitoring - I often get a sore throat when I have lots of meetings, so I use the 2nd headphone monitor as an extremely loud monitor of my audio. That helps me talk softly, but an unprocessed version is sent to the conference. As the gain is so high, the background noise is loud, so I also add a gate on my monitor to make it less fatiguing.
Hopefully that gives you an idea of the flexibility of this unit.
The build quality is great, very solid. As others have said, the screen is a bit hard to read especially if there are reflections. The knob clicks too loud. And there could be more knobs/buttons, to make less combinations to change presets, adjust levels etc.
Sound quality is excellent, very low noise and a lot of mic gain. 2 monitors is also very nice. I never send the mic through the first monitor so I can't ever get feedback issues when I have my loud speakers on.
The bundled plugins seem good, but I'm just learning how to use them tbh. I would have liked some more 'basic' stuff like the ableton limiter, gate. Everything is 'vintage'. It would be amazing to load a VST into it and have it stored for use without the PC.
I had problems with some of the plugins not working, but the antelope support has been very fast to help and by using an older firmware I have all the plugins working now.
Expensive, but does the job and lets me do pro level audio processing without a windows / mac computer.
