Yamaha PX5 Power Amplifier


Since the 1976 release of the P2200, our first professional power amplifier, we've strived to achieve the highest possible levels of sound quality, power output, and reliability in sound reinforcement, studio, and installed applications.

The new PX Series power amplifiers continue this tradition of excellence, utilising Yamaha’s renowned digital signal processing technology and unparalleled professional audio expertise to achieve a light, durable design, capable of delivering maximum output power to the speakers while simultaneously protecting them with optimized processing.

Driven by a newly-developed Class-D amplifier the four new models that make up the PX Series are suitable for a broad range of sound reinforcement and installation environments.
