Yamaha PX3 Power Amplifier

The versatile PX3 power amplifier combines intelligent processing with high output power to meet the requirements of a vast range of sound reinforcement environments. Since the 1976 release of the P2200, Yamaha's 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. PX series models come with flexible onboard PEQ, crossover, filters, delay, and limiter functions as standard, allowing quick and easy system setup via the LCD display, without the need for any additional outboard gear. All models also feature Yamaha's intelligent D-CONTOUR multi-band dynamic processing, allowing users to achieve consistent clarity and high-quality sound at any output level by tailoring the frequency response of each connected speaker for either front-of-house or monitor configurations.
