NEC M-50
monoblock amplifiers






"The M-50 incorporates NEC's world famous electronics technology to give you a degree of high-fidelity, high-density audio reproduction that has been hitherto unobtainable. The M-50 is truly a power amplifier suited to the age of digital audio."

  • The monaural M-50 power amplifier is the ultimate expression of the "simpler is better" philosophy. Monaural power amplifiers easily exceed the performance of stereo amplifiers as speaker drives and also eliminate mutual interference between channels.
    • Because of the unit's small size it is possible to create a stereo amplifier system in which even the power cords are independent on the left and right sides.
    • The M-50 is also perfect for use as a multi-channel amplifier.
  • With it's stable power stage and high efficiency, the unit's effective output can easily clear 100 watts at 4 ohms.
  • Large flourecent POWER METER display. this meter allows you to monitor output changes from 1 mW to 200 W (4 ohms). The POWER METER may also be switched off when necessary.
  • The M-50 incorporates a high and low filter system which allows you to make 5 position crossover frequency changes. This allows the M-50 to be used as a multi-channel amplifier as well as to cut unwanted signals.
  • The M-50 has:
    • Filed Brass input pin jacks.
    • Twin crossbar metal connector relays.
    • Large size speaker terminals for high quality audio reproduction.
