The ground-breaking intuitive front panel is clear and easy to use without any unnecessary bells and whistles. The volume control rotary on the front panel is prominent, illuminated, bigger and put in the forefront while the mic volume control is smaller and recessed.

This class-d mixing power amplifier offers 120 watts in 70 or 100 volt mode and comes with three mic inputs balanced, along with four stereo line, mono summed inputs.

The MA120 is a 120W single channel mixing amplifier. Designed for ease of use, the front panel of the MA120 includes volume and microphone controls, providing immediate visual feedback regarding system operation. The MA120 is equipped with four priority levels for audio routing: one emergency input, one paging input, two mic/line inputs, and four stereo line, mono summed inputs. It’s audio performance, easeof-use, and versatile feature set makes the MA120 ideal for a variety of professional audio applications.
