Technical Data

  • Continuous power (at distortion factor)
    • 8 Ohm: 2x 270 W, 1x 840 W
    • 4 Ohm: 2x 420 W, 1x 1,100 W (manufacturer's specification)

My trusted technician did the math when I picked up my P500L from his repair shop on 08/10/2020, and he came to the conclusion that at 4 ohms there is a little over 1000 W of amplifier power. As usual Accuphase underplays with their power specifications, here especially ;-) 2 Ohm: 2x 550 W

  • Dynamic power/music power

4 Ohm:

  • Total harmonic distortion:
    • Stereo mode: 0.02% (2 Ohm), 0.01% (4-16 Ohm)
    • Mono mode: 0.02% (2 Ohm), 0.01% (4-16 Ohm)
  • Attenuation factor: 500 (stereo), 250 (mono)
  • Frequency response:
    • Rated power: 20 - 20,000 Hz (+0, -0.2 dB).
    • at 1 Watt: 0.5 - 180,000 Hz (+0, -3 dB)
  • Signal-to-noise ratio: 120 dB
