Well, they certainly aren't consistent. Look up an EP1500 and it doesn't say RMS, but does give you output at 1kz and output at 20-20kz. Then look up an EP4000, it give RMS and Peak......
You have to look either in the spec sheets or the manual for their numbers - the marketing info always quote ratings at 2 ohms stereo and/or 4 ohms bridged to look better.
I've just had another look at the EP4000 on the Behringer site.
The only place where power is specified is near the top:-
"2 x 2,000 Watts into 2 Ohms; 2 x 1,400 Watts into 4 Ohms; 4,000 Watts into 4 Ohms (bridge mode)".
I can't find any mention of what they mean by "watts".
However, I downloaded the manual.
The back page has full specifications, including "
RMS @1%THD (sine wave) both channels driven".
Putting it in the same format as above, the RMS specs are:-
2 x 1,250 Watts into 2 Ohms; 2 x 950 Watts into 4 Ohms; 2 x 550 Watts into 8 Ohms; 2400 Watts into 4 Ohms (bridge mode)
"
Peak Power, both channels driven" is also specified:-
2 x 2000 Watts into 2 Ohms; 2 x 1400 Watts into 4 Ohms; 2 x 2000 Watts into 8 Ohms; 4000 Watts into 4 Ohms (bridge mode).
So obviously the power quoted on the web page is PEAK. You have to download and read the manual to ascertain the RMS values.
Note also that the power is quoted at 1%THD, not 0.1% as some high quality amps do.
It's a real minefield trying to find specs that allow direct comparisons between brands.
