Yamaha PX8 Dual Channel Stereo Power Amplifier
The new PX series power amplifiers utilize Yamaha's renowned digital signal processing technology and unparalleled professional audio expertise to achieve a light, durable design, capable of delivering maximum output power to the speakers while simultaneously protecting them with optimized processing.
PX series models are 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 PX Series amplifiers supremely efficient amplifiers with low noise, reliable protection features, and above all, outstanding sound quality.
Features:
• DSP for audio processing - Input Routing & Output Routing
• Flexible onboard crossover, filters, delay, limiter and PEQ functions come standard, allowing quick and easy system setup via the LCD display
• D-CONTOUR multi-band dynamic processing for consistent clarity and high-quality sound for either front-of-house or monitor configurations
• 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
• Config Wizard allows users to save even more time during system setup by assigning optimized speaker settings that match your system configuration
• XLR and TRS inputs, binding post, SpeakON and phone outputs
• Sturdy chassis and carrying handle
