Yamaha PA2120 //E Power Amplifiers

The Yamaha PA2120 is a powerful and flexible Class-D power amplifier designed for professional and commercial audio installations. With support for both low-impedance (Lo-Z) and high-impedance (Hi-Z) speaker systems, it is ideal for retail environments, restaurants, houses of worship, and multi-zone installations.

Delivering up to 120W per channel in stereo or 200W in bridged mono mode, the PA2120 offers excellent performance and versatility. It features advanced DSP processing including output EQ, speaker optimization for Yamaha VXC/VXS series, and selectable high-pass and low-pass filters.

The PA2120 also supports dual-zone operation, allowing independent control of source and volume in two areas. Additional units can be added to expand system zones, making it ideal for scalable installations.
