How can I convert RMS to PMPO ?

Question

How can I convert RMS to PMPO ?

Answer 1

You cant convert between the two.



RMS stands for Root Mean Square. First a varying quanity is squared, then the average is taken, then the square root. This gives an average "typical" value.



PMPO stands for Peak Music Power Output. There is no industry standard for PMPO so you don't really have any way to find out what it means. PMPO in all likelyhood varies between manufactures, and was calculated by their marketing department. Meaning they picked a number that sounded really cool, then figured out a formula that would result in that number.

Answer 2

Rms To Pmpo Conversion

Answer 3

I want to convert 40 rms to pmpo.

Please give me answers.

Answer 4

Be very careful by equipment that rates it power in PMPO, this is very often false and very inaccurate. The 0.707 theroy is good advice which most compaanies should use, but they don't. A 10 watt amp can produce stupid amounts of peak power, a peak transient can be thousdands bigger for a micro second and most companies will use that figure insted of the 0.707 theroy. It will never be able to replicate those lab testing conditions when you purchase it though

Answer 6

AC power, which includes audio power, is best measured as an average power, commonly called "watts RMS". This is the accurate method. It is based on this formula:







In the case of a sinusoidal tone (not music) into a purely resistive impedance (not a speaker), use this formula:







An ideal (100% efficient) amplifier with a 12-volt peak-to-peak supply can drive a signal with a peak amplitude of 6 V. In an 8 ohm (see impedance) loudspeaker this would deliver:



Ppeak = (6 V)2 / 8 Ω = 4.5 watts peak instantaneous.

If this signal is sinusoidal, its RMS value is 6 V × 0.707 = 4.242 V(RMS). This voltage into a speaker load of 8 Ω gives a power of:



Pavg = (4.242 V)2 / 8 Ω = 2.25 watts average ("RMS")

Thus the output of a typical car audio amplifier is limited by the peak voltage of the battery. (This is why high-end car audio equipment uses a DC-to-DC converter to generate a higher supply voltage at the expense of drawing more current from the battery).



The true power output of an amplifier can be estimated by examining the input current. Linear amplifiers tend to be about 60% efficient at best. An amplifier labeled "500 W PMPO" but fitted with a 5-amp fuse can therefore deliver an average power of 5 A × 14.4 V × 60%, or about 43 watts.



It is not uncommon to see two apparently incompatible claims in a list of technical specifications of sound equipment, for instance, a "4500 watt PMPO" delivered from a "fitted plug with 3 A fuse"
