Quick Overview

Yamaha PX3 Power Amplifier

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.

The versatile PX series power amplifiers lineup combines intelligent processing with high output power to meet the requirements of a vast range of sound reinforcement environments. 300W x 2 at 8Ω / 500W x 2 at 4Ω.

  • 2x 300W at 8Ω
  • 2x 500W at 4Ω
  • Newly developed Class-D amplifier engine with a custom LSI
  • Flexible onboard PEQ, crossover, filters, delay, and limiter functions
  • Yamaha Speaker presets
  • Utlities for safe and secure operation
