Yamaha MA2120 Power Amplifiers

The Yamaha MA2120 is a versatile mixer amplifier designed for commercial and professional audio installations. Combining powerful amplification with flexible mixing capabilities, it is ideal for retail stores, restaurants, classrooms, houses of worship, and conference spaces.

Delivering 120W per channel at 4 ohms (or 100W per channel at 8 ohms), the MA2120 supports both low-impedance and high-impedance (70V/100V) speaker systems, making it highly adaptable for various installation types. Built-in DSP processing—including feedback suppression, priority control, and EQ—ensures clear and reliable sound performance.

Its compact half-rack design allows for easy installation on a desk, under a counter, or in a rack using optional mounting hardware.
