Description
The MA2120 is a professional Class-D mixer power amplifier designed for both low-impedance (Lo-Z) and high-impedance (Hi-Z) speaker systems. It delivers reliable audio performance for PA systems, background music, announcements, and microphone applications. The amplifier supports 70V/100V line operation and low impedance outputs, making it suitable for commercial installations such as schools, offices, malls, railway stations, factories, and public address systems. It includes built-in DSP processing for improved sound quality and easy audio management.
