High-Power Stereo Amplifier for Professional Sound Systems
The Yamaha PX8 is a two-channel Class-D power amplifier built to deliver dependable, high-output performance for live sound, installed audio, and portable PA systems. Rated at 800 watts per channel into 8 ohms, this amplifier provides the headroom and control needed to drive full-range speakers or stage monitors with confidence while maintaining a compact, lightweight form factor for easy transport and rack mounting.
Efficient Class-D Design with Advanced Processing
At the heart of the PX8 is a highly efficient Class-D amplifier stage powered by a custom Yamaha LSI chip with PLL technology. This design reduces heat, lowers noise, and improves overall efficiency without sacrificing audio clarity. The result is consistent, clean power delivery that performs reliably across long events, rehearsals, and demanding sound reinforcement applications.
Built-In DSP for Speaker Protection and System Tuning
Integrated digital signal processing gives users precise control over system performance without external processors. The onboard DSP includes parametric EQ, crossover functions, filters, delay, and limiters, allowing detailed adjustment of input sensitivity, routing, amplifier gain, and speaker impedance. These tools help protect connected speakers while ensuring the system is tuned for the room and application.
D-Contour Dynamic Processing for FOH and Monitor Use
Yamaha’s D-Contour multi-band dynamic processing shapes the frequency response of connected speakers based on how the amplifier is used. Whether configured for front-of-house sound or stage monitoring, D-Contour maintains tonal balance and clarity at varying volume levels, helping mixes stay consistent even as output demands change.
Configuration Wizard for Faster Setup
The PX8 includes a built-in Configuration Wizard that simplifies setup by assigning optimized speaker presets based on your system configuration. Users can choose a basic mode for fast deployment or an advanced mode for deeper DSP control. Up to eight presets can be stored internally or saved to a USB drive, making it easy to recall settings across multiple venues or amplifier units.
Road-Ready Construction and Secure Operation
Designed for regular transport and long-term use, the PX8 features a durable chassis with an integrated carrying handle and efficient variable-speed cooling fans. A panel-locking function prevents accidental changes during operation, ensuring settings remain secure throughout performances, installations, or unattended operation.
