Yamaha's PX5 2 channel Class D power amplifier (800W, with EQ, Filter, Crossover, Delay, Limiter, and Power Boost Functions) gives you more than great-sounding amplification. It packs powerful built-in processing that would normally require external PA management processing.
The versatile PX series power amplifiers lineup combines intelligent processing with high output power to meet the requirements of a vast range of sound reinforcement environments. 500W x 2 at 8 ohms/ 800W x 2 at 4 ohms.
Fine-tune output channels with equalization, and add limiting to protect speakers from dangerous signal spikes. Dial in crossovers to integrate subwoofers and fill speakers. Use the built-in delay network to ensure phase coherency across all speakers in larger rigs. And all of these advanced features are easily accessible from the LCD display.
