UR22C - use as standalone direct monitor

Hi, does anyone know, if the UR22C can be used as a direct monitor without connecting to PC/Mac? Of course considering first proper setup, but then I would want to occasionally use it without my PC, using an AC adaptor.

Thank you for help!

I’m frequently doing just that with my 44C.
Cannot be 100% sure, but most probably works fine with the 22C as well.

I have the older version, UR44 (usb 2.0) and one thing I’m able to do is to adjust different settings in the DSPMIX app (without saving any preset) and then run the unit in standalone, and all my settings will remain which is amazing because I use the UR44 with my MPC (class compliant). I know the DSPmix app in the C series is newer but looks very similar. I’m wondering if that fucntion still works? Will the UR44C retain all the settings once I use it in standalone mode? Thanks!
