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:
