Headroom Notes
125 W into 8 ohms over the full band at 0.05 % THD is the comparable number. Denon also prints a 'Dynamic power' row - 130 W x 2 into 8 ohms, 190 W x 2 into 4 ohms - and that is the only 4-ohm number this receiver has. Dynamic power is a short-burst measurement; there is no continuous 4-ohm rating anywhere in the manual, even though the manual permits 4-ohm speakers.
What the datasheet actually says
Quoted verbatim from the manufacturer’s own page, with the date we checked it. We state what is printed, not what anyone intended by it.
«Dynamic power: 130 W x 2-channel (8 Ω/ohms) / 190 W x 2-channel (4 Ω/ohms)»
This is the only figure the AVR-X4800H publishes for a 4-ohm load, and it is not a continuous rating. Dynamic power is measured with short tone bursts, so the supply and the heatsinks are never asked to hold it. Placed next to the rated output rows it reads like a 4-ohm power rating, and the receiver has none.
