  • Notes

  • The Direct Energy MOS Power Amplifier harnesses the power of cutting-edge Direct Energy MOS FET devices, renowned for their high performance. Combined with Pioneer's innovative Wide Range Linear Circuit technology, this amplifier delivers a remarkable feat: reduced power consumption without sacrificing output power.

    In simpler terms, the amplifier operates with exceptional efficiency, drawing less power while maintaining its robust audio output. This translates to stunning performance across the entire audio spectrum, characterized by a flat damping factor and enhanced power linearity, ensuring faithfully reproduced and impactful sound.

    Specifications:

    • DIN-Power output: 55 watts per channel into 8 Ω at THD 1.0%
    • Frequency response: 5Hz to 100kHz
    • Total harmonic distortion: 0.05%
    • Input sensitivity: 2.8mV (MM), 200mV (line)
    • Signal-to-noise ratio: 86dB (MM), 106dB (line)
    • Output: 200mV (line)
    • Accessories: Remote Control
       

    AC Power supply depends on the country of destination.
