About Yamaha PX5

Where professional audio performance meets cutting-edge technology, the Yamaha PX5 Stereo Power Amplifier stands as a testament to the brand's dedication to sound reinforcement and installation excellence. Since the debut of the P2200 in 1976, Yamaha has consistently pushed the boundaries of sound quality, power, and reliability. The PX5 continues this legacy, boasting a robust 800W output at 4 Ohms per channel, making it an ideal choice for large venues and demanding audio environments.

Crafted with a high-quality, newly developed Class-D amplifier engine and a custom LSI chip, the PX5 ensures efficient, high-fidelity amplification. Its advanced design is complemented by PLL technology, which maintains precise control over transfer characteristics, delivering powerful, clear, and dynamic audio performance.

The PX5 is not just powerful; it's smart. With onboard DSP for intricate audio processing, users can effortlessly manage input and output routing with 15 selectable patterns, including Dual, Parallel, Single, and SUM configurations. The amplifier supports various speaker system structures, such as FULL+FULL, SUB+SUB, FULL+SUB, Bi-Amp, Boost Full, and Boost Sub, providing unparalleled versatility for any setup.

For those seeking even more power, the PX5 features a Power Boost Mode, which consolidates the output from two channels into one for increased single-channel power, ideal for driving high-power speakers. This flexibility ensures the PX5 can adapt to a multitude of sound reinforcement scenarios.

Yamaha's sophisticated signal processing is at the heart of the PX5, with onboard crossover, filters, delay, limiter, and PEQ functions as standard. The inclusion of Yamaha's intelligent D-CONTOUR multi-band dynamic processing guarantees consistent clarity and high-quality sound, whether for front-of-house or monitor configurations.

Ease of use is paramount with the PX5. The amplifier offers Basic and Advanced setup modes to accommodate all levels of sound reinforcement experience. Basic mode simplifies system configuration for novices, while Advanced mode grants precise control to seasoned professionals. Eight programmable presets enable instant recall and reduced setup time, with the added convenience of USB transferability for sharing settings across PX amplifiers.

The Config Wizard streamlines system setup further by providing optimized speaker settings based on the system configuration. With presets tailored for Yamaha's extensive passive speaker lineup and an advanced mode for detailed parameter configuration, the PX5 ensures a perfect match for any audio setup.

Durability and connectivity go hand in hand with the PX5. It features a variety of input and output options, including XLR and TRS inputs, as well as binding post, SpeakON, and phone outputs. The rugged chassis and convenient carrying handle are designed for the rigors of road use, ensuring the PX5 is ready for any event.

Safety and security are also top priorities. The PX5 simplifies panel settings configuration, monitors amplifier status, and facilitates data transfer via USB. A panel locking function prevents unauthorized adjustments, and the ability to export device and log data to USB aids in quick troubleshooting.

In summary, the Yamaha PX5 2x 800W 4 Ohms Stereo Power Amplifier is a powerful, efficient, and versatile solution for professional audio setups, delivering the high-quality, reliable performance that Yamaha is renowned for. Whether for live sound, installations, or studio applications, the PX5 is engineered to exceed expectations and elevate audio experiences.
