Key Info
Yamaha PX5 is a 2-Channel, 500W Power Amplifier

Efficient, Lightweight Technology

With Class-D amplification, the PX5 is capable of providing an incredibly powerful, reliable performance housed within a lightweight enclosure. The amplifier components are compressed into a single chip and allows real-time signal transfers to generate excellent sound quality and power. Combining the classic Yamaha digital signal processing technology with Class-D amplification results in an extremely efficient power amp with low noise, high-quality protection and outstanding sound quality.

Unrivaled Signal Processing

Users can setup the PX5 with ease thanks to the intuitive LCD display and the wealth of control options provided. Each PX model features an integrated PEQ, crossover, filters, delay and limiter functions. With innovative D-CONTOUR processing, users can consistently maintain high-quality sound full of clarity at any output level.

Simple Setup

There are two setup modes onboard the PX power amplifiers, ideal for any level of sound engineer. The basic setup mode offers simple setting options for a quick and stress-free experience whilst the advanced mode offers users precise control over every detail within the sound. To reduce setup time even further, there are 8 integrated programmable presets that can even be transferred via USB to other PX amplifiers.

Intelligent Config Wizard

The Config Wizard component further streamlines the setup process. Users choose the filter and crossover settings for the speakers in use and the Config Wizard completes the setup. There are also presets designed for use with a wide variety of Yamaha passive speakers such as the CBR Series. Furthermore, the advanced setup mode lets you fine tweak the configuration to your ideal settings by altering parameters such as input routing, sensitivity, amp gain and speaker impedance.
