Yamaha PX3 300W Stereo Power Amplifier

Yamaha PX3 Stereo Power Amplifier

The Yamaha PX3 Stereo Power Amplifier delivers 300W at 8 Ohms in a lightweight chassis suitable for various sound-reinforcement applications. Part of the PX Series, this amplifier features a Class-D engine with a custom LSI chip and PLL technology for higher efficiency and reduced noise. The Power-Boost mode combines output from two channels into one for higher single-channel power levels.

The onboard DSP functions include a PEQ, delay, crossover, and limiter, enabling detailed configuration of parameters such as input/output routing, sensitivity, amp gain, and speaker impedance. The D-Control multi-band dynamic processor provides clear, consistent sound by shaping the speakers’ frequency response, suited for front-of-house or monitor configurations.

A Configuration Wizard saves setup time by assigning optimized speaker settings for your system, with basic and advanced modes available for different levels of control. Up to eight presets can be stored and transferred via USB. The panel-locking function secures settings, while the sturdy frame and carrying handle ensure durability for extended use.
