Biamp MA60 (Apart)

The compact 9.5” MA60 mixing amplifier has an unseen intuitive user-friendly interface and groundbreaking logical rear panel. The unit comes with 1 mic/line input and 2 stereo line, mono summed inputs. On the rear you can find smart left-to-right 4 level priority system for audio routing, an emergency input, paging mic with chime and a 24VDC override output. The design of the MA60 is a true redefinition of the mixing amplifier that goes back to the basics.
