[Amps] RMS-PEP & 2x8877

[Martin, Maximo]

RMS is an average measurement, efective power instead PEP, it's peak to
peak. 
If you take one peak without flat-topping you have the RMS, but it is from
the half of the total, in a graphic you use only the upper half part of the
signal, but PEP is from the top peak to the bottom peak so it is more than
double, it is 2.25 times.

I 




2 x 8877 are able to run about 4.5 to 5 Kw out, but this is a RMS 
measurement. The PEP value is the RMS x 2.25 so; 4.5 x 2.25= + 10000 W 

Max. 




Hello Max, 

Please explain why PEP should equal 2,25 x RMS wattage? 

For my knowledge so far PEP ist the RMS wattage at the peak of the 
envelope without flat-topping.
