Yamaha PX5

Stereo Power Amplifier

  • ₦216,000.00


The Yamaha PX5 Stereo Power Amplifier delivers 500W at 8 Ohms in a lightweight chassis and is suitable for a wide variety of sound-reinforcement applications. Part of the company's PX Series of power amplifiers, it features a Class-D engine with a single custom LSI chip, and uses PLL technology for higher efficiency and lower noise. The Power Boost mode combines the power output from two channels into one, achieving significantly higher single-channel power levels (the number of channels available is then halved).
