Yamaha PA2030a Power Amplifiers

The Yamaha PA2030a is a compact Class-D power amplifier designed for commercial audio installations requiring flexible speaker configurations. It supports both low-impedance (Lo-Z) and high-impedance (Hi-Z) systems, making it ideal for retail stores, restaurants, classrooms, and small public address systems.

Delivering 30W per channel in low-impedance mode or 60W in high-impedance mode, the PA2030a provides efficient and reliable performance in a space-saving design. It features built-in DSP including speaker EQ optimized for Yamaha VXC/VXS series speakers, along with high-pass and low-pass filters for system tuning.

The amplifier can be used as a standalone unit or paired with the Yamaha MA2030a mixer amplifier for expanded system flexibility.
