Hello

please tell me if the mentioned power in the data sheet is RMS , PEAK , AVERAGE ???

0 Jesse Ji 6 months ago

they are all peak power the device can get.

it was calculated by maximum Vrms the amplifier can output.

thanks

YOUR REPLAY IS NOT UNDERSTANDABLE

where you cannot understand?

pls explain more in detail.

is it RMS or PEAK values ?

0 Jesse Ji 6 months ago in reply to ilya tashaev

for example:

when input increase, the amp's output voltage also increase.

when thd = 1%, the output voltage can get A vols. here the A usually means rms value. the peak voltage is A*sqrt(2).

then we use A^2/Rload = power.

this power is what we listed in above DS.

generally, power use the Vrms to calculate.

if there are special description peak power, then here might use peak voltage to calculate the power.

so what exactly your rms and peak means?
