Snaga sistema
#31
Kad bi recimo slušali Vinylku dobrog snimka dinamike 24-27dB izmedju najtišeg i najglasnijeg tona neke numere/pasaže,
i da RIAA pre tu snimku sa lakočom pojača bez da več ona ulazi u svoj "plafon", to jest naponski klipping,
kad bi slušali najtiše tonove sa 1Wrms/8R0 ili naših referentnih 0dB,

onda bi trebali imati sistem pojačalo+napajanje+zvučnici koji moraju da razviju proporcionalno i najglasniji ton od +27dB,
kao što je več Bocko istabelirao, svakih 3dB znači nam dva puta veču snagu sistema,
nečemo uzeti u obzir disperziju zvuka u prostoru, imamo samo jedan zvučnik, ako jih je više svaki dodatni par tvore +3dB...
Mono = 0dB, Stereo =+3dB, Quadro = +6dB...


što nam dodje 27dB/3dB = 9X , i onda snagu svaki put dupliramo
tako dobijemo proporciju snage = 2^9 (dva na devetu pot.) = 512Wrms/8R0 (+27dB)

A da nebi bio naš sistem zakucan na svoj "plafon", volimo pojačala da imaju koji +dB zalihe od deklarirane snage,
pa neka je obilatih +3dB od deklarisanog i evo brzo potrebnih KWrms snage.

A ko sluša najtiše tonove sa 1Wrms snage sa zvučnicima 92dB/1W/1M, što je več visok SPL?
