The Mackie Onyx Producer 2-2 is a USB audio/MIDI interface designed for high-resolution recording and monitoring in home and project studios. With its dual Onyx microphone preamps, combo XLR-1/4" inputs, and 5-pin MIDI I/O, the unit is particularly suitable for singer-songwriters and producers who make use of MIDI instruments and MIDI hardware. In your own project studio, you'll be able to connect to your monitors by means of the 1/4" jacks located on the rear of the unit.
