The little brother, if you will, to the UMC22.
The key differences from the above are:
- Plastic chassis
- Smaller, compact form factor (dials are on the top)
- RCA Outputs
- XENYX Mic Preamp (MIDAS Preamp on the 22)
Apart from those, both have 48v phantom power and the same amount of IO.
From what I read and hear, both perform the exact same but this is slightly cheaper (I'm assuming to the above).
