Power Amplifiers

Intelligent Processing. Serious Power.

Since the 1976 release of the P2200, our first professional power amplifier, Yamaha has 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, utilizing 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.

Key Features

Powerful, Efficient Design

PX series models are driven by a newly developed Class-D amplifier engine with a custom LSI.

Flexible Connectivity, Durable Construction

To adapt wide variety of user experience, PX series to be prepared Basic mode and Advanced mode.

Flexible user set up

Utilities for Safe and Secure Operation

PX Series amplifiers make it easy to transfer data such as panel settings and monitor data via USB for use with other amplifiers and setups, and also feature a panel locking function to keep your settings safe.


With a lineup comprising four new models – 1,200 W x2 PX10, 1050 W x2 PX8, 800 W x2 PX5, and 500 W x2 PX3* – the PX series offers a versatile range of different power output capabilities suitable for a wide variety of sound reinforcement applications. The PX3 and PX5 also come equipped with a Power Boost Mode that combines the power output from two channels into one, achieving significantly higher single-channel power levels to drive high power handling speakers when needed (note that the number of channels available is halved in this case).
