In the avr spec sheet something like this: (this is from the Denon A1H flagship specs):Hello. Thanks for answering. Please define "dynamic".
Dynamic power:
170 W x 2-channel (8 Ω/ohms)
280 W x 2-channel (4 Ω/ohms)
Sometimes it'll be indicated at 8, 6, 4 and 2 ohm with a wattage figure for each. It's not full band or at a specified distortion level.
