Both the 7500 and 7700 have a maximum power consumption of 1800 watts in specsheet.
But how can that be ....the 7500 is 200 x 5 and the 7700 is 200 x 7.
should'nt the 7500 use less power ?
Also what do they draw at idle and low output....10 - 40 watts per channel which is where they'll run much of the time ?
