Headroom Notes
150 W into 8 ohms and 250 W into 4 ohms. The published distortion figure, 0.0011 %, is measured at 1 W - a 150 W amplifier's behaviour at one watt says nothing about its behaviour near clipping, so it is not recorded against either power rating.
Thermal Behavior
4 and 8 ohm speakers are both supported, per the shared Evo manual. Note the power ratio between the loads is 1.67, not 2 - the class D module runs out of supply before it runs out of current.
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.
«THD: 0.0011% 1kHz at 1W, 20Hz - 20kHz BW»
This is a 150 watt amplifier and the distortion figure is taken at one watt - roughly 0.7 % of rated output. Distortion in a class D output stage is lowest in the middle of its range and rises towards clipping, so a one-watt figure is the most flattering point on the curve and cannot be compared with a manufacturer that quotes distortion at rated power.
