      VOLT 4 is shockingly good!

      I bought this to use as an inexpensive aggregate device. I am surprised at the clarity of the pre's and of the line inputs. It functions well in my system alongside my Apollo Twin X.

      Small and Portable Audio Interface with user friendly DAW

      This audio interface record beautiful sound. It comes with Live 11 Element which is very user friendly. The cons is that it has only two mic/line inputs; the 3/4 line inputs have no volume control.
