Folks, I don't understand these measurements, maybe someone can explain them to me.

It appears that the individual amplifiers are clipping limited to about 202 watts at 8 ohms (pretty simple).

Then it appears that 5 amplifiers are power supply limited to 145 watts at 8 ohms (725 watts from the power supply, efficiencies neglected).

Yet, we have 7 amplifiers running 139 watts each at clipping (973 watts from the power supply, efficiencies neglected).

So, where did the extra 248 power supply watts come from? Or, conversely, why didn't the 5 channel test run about 195 watts per channel.

What are the limiting factors here?
