No thanks. The UA-25 is bus powered, has two XLR+jack inputs, phantom power, rca/jack outputs, direct monitor, individual channel gain control, master gain control, and in a road tuff metal case. I have two of them, so it makes sense to dump the PI if I can't get it to work with proven linux friendly hardware especially when the pi costs less.
Too bad.
