Yamaha PX8 Power Amplifier

The Yamaha PX8 Power Amplifier delivers 800W at 8 Ohms and is suitable for a wide variety of sound-reinforcement applications. The on-board DSP functions, and D-Control multi-band dynamic processor delivers a clear and consistent sound at any output level by shaping the frequency response of each speaker for either front-of-house or monitor configurations.

The Yamaha PX8 Power Amplifier is designed to achieve the highest possible levels of sound quality, power output, and reliability in sound reinforcement, studio, and installed applications.

Powerful, Efficient Design
The Yamaha PX8 is driven by a newly developed Class-D amplifier engine 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 Yamaha PX8 is supremely efficient amplifier with low noise, reliable protection features, and above all, outstanding sound quality.

Versatile Lineup
With a lineup comprising four new models – 1,200 W x2 PX10, 1050 W x2 PX8, 800 W x2 PX5, and 500 W x2 PX3 – the Yamaha 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 (note that the number of channels available is halved in this case). (Power output figures rated at 4 O).

Sophisticated Signal Processing
Yamaha PX8 comes with flexible onboard crossover, filters, delay, limiter and PEQ (fixed preset) functions as standard, allowing quick and easy system setup via the LCD display, without the need for any additional outboard gear. It 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.

Easy, Intuitive Setup
To accommodate users with varying levels of sound reinforcement experience, the Yamaha PX8 offers both Basic and Advanced setup modes. Basic mode allows even inexperienced users to easily configure a system that meets their needs, while Advanced mode offers experienced users more precise control over every aspect of their sound. It features eight programmable presets for instant recall and reduced setup time that can be saved to a USB thumb drive and shared with other Yamaha PX amplifiers.

Smart Configuration Wizard
The Config Wizard allows users to save even more time during system setup by assigning optimized speaker settings that match your system configuration– simply select the appropriate filter and crossover for each speaker, and Config Wizard will do the rest. Config Wizard also features presets specifically tuned for each model in Yamaha’s extensive lineup 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. Presets may be added and updated in the future.

Flexible Connectivity, Durable Construction
Equipped with both XLR and TRS inputs, and binding post, SpeakON and phone outputs, 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.

Utilities for Safe and Secure Operation
Yamaha PX8 Amplifier makes it fast and easy to configure panel settings, monitor amplifier status, and transfer data via USB, and 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.
