How can the power output exceed the power input????
Hello all, i have wanted to know this for a while , some of the avrís on the market have rated power outputs (continuous or rms) that are more than the rated power input in watts , how is this ??
For example i have a borrowed denon avr 1509 and the rated power input in watts is 360 . and the sums rated power outputs are (75w*5ch) = 375w @ 8ohm . or (110w*5ch)= 550w .
How can this be ??
Cheers ed :-)
