mia adus cineva un cd player din germania si nu vad nimic cati watti rms are decat Maximum Output Power 4x20 oare astia is rms ? nu aruncati cu topoare in mine ca nu stiu

[perta]

are ~10W RMS...
ce pacat ca nu am toporu langa mine

[TheDragon]

ceai ma esti cu capu !! ) esti sigur?

[KRZ]

maxim 20 poate sa fie si mai putin de 10 zi exact numele si cautam pe net deci cam pe atat te poti baza nu e regula sa fie rms jumate din max

[TheDragon]

dar totusi sa nu confundam
Peak Music Power Output (PMPO) (sometimes misused in advertising as Peak momentary performance output) is a much more dubious measure, of interest more to advertising copy-writers than to consumers. The term PMPO has never been defined in any standard but it is often taken to be the sum of some sort of peak power for each amplifier in a system. Different manufacturers use different definitions, so that the ratio of PMPO to continuous power output varies widely; it is not possible to convert from one to the other. Peak power is twice the sine wave power, so, for example, a 5 channel system using amplifiers which can output 10 watts for a few milliseconds with an unspecified percentage of distortion would be specified as '100 watts PMPO'. Sometimes, an extra factor is applied to get an even higher figure. The term PMPO is considered misleading and meaningless by audio professionals. Most amplifiers can sustain their PMPO for only a very short time; loudspeakers are not designed to withstand their stated PMPO for anything but a momentary peak without serious damage. Sometimes the PMPO which can be delivered into an unrealistic resistive load, rather than a real loudspeaker, is quoted. There have been genuine attempts to measure 'peak music power' as described below, but in general the term is not at all useful


am avut si eu niste porcarii care scria pe fata PMPO ! cum se poate masura cat watti are amplificatorul ?? dupa capatana mea as baga watt- metru ! alte pareri ?
