Yamaha PX Series Amplifiers

Since the 1976 and the release of the P2200, Yamaha has striven 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. Driven by a Class D amplifier the four new models of this Series are suitable for a broad range of sound reinforcement and installation environments.

The PX series are driven by a newly developed Class D amplifier that concentrates all the necessary functions into a single custom LSI chip and uses PLL technology to control transfer characteristics in real time, achieving impressive sound quality and power. This new single chip architecture offers higher output and improved performance in a more lightweight, yet reliable design. A combination of cutting edge technology and an exhaustive component selection process make these PXs supremely efficient amplifiers with low noise, reliable protection features and above all, outstanding sound quality.

With a line up comprising four models 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.

Please Note: The number of channels available is halved in this case. Power output figures rated at 4 Ω.

These models come with flexible onboard crossover, filters, delay, limiter and PEQ, fixed pre-set functions as standard, allowing quick and easy system setup via the LCD display, without the need for any additional outboard equipment. All models also feature Yamaha’s intelligent D-CONTOUR multi band dynamic processing, allowing users to achieve consistent clarity and high quality sound for either front of house or monitor configurations.

To accommodate users with varying levels of sound reinforcement experience, the PX series offers both Basic and Advanced setup modes. Basic mode allows even inexperienced users to easily configure a system that meets their needs. Advanced mode offers experienced users more precise control over every aspect of their sound. All models feature eight programmable pre-sets for instant recall and reduced setup time that can be saved to a USB thumb drive and shared with other PX amplifiers.

The Configuration Wizard allows users to save even more time during system setup by assigning optimised speaker settings that match system configurations. Simply select the appropriate filter and crossover for each speaker and the Config Wizard will do the rest. This Wizard also features pre-sets* specifically tuned for each model in Yamaha’s extensive line up of passive speakers, including the popular CBR, Club, Installation and VXS/VXC series, and an advanced mode that allows more detailed configuration of parameters such as input routing, input sensitivity, amp gain and speaker impedance. *Pre-sets may be added and updated in the future.

Equipped with both XLR and TRS inputs and binding post, SpeakON and phone outputs, Yamaha's PX Series amplifiers offer the flexibility needed for a variety of setups and environments and the durability to stand up to extended road use thanks to the sturdy chassis and carrying handle design.

The PX Series amplifiers make it fast and easy to configure panel settings, monitor amplifier status and transfer data via USB. They also feature a panel locking function to keep your settings safe. Users can even export information such as internal device and log data to USB for rapid troubleshooting should difficulties arise.
