1. Wokamba: kuti athe kupirira kugwedezeka kwamphamvu mwadzidzidzi mu chizindikiro cha pulogalamu popanda kuwonongeka kapena kupotoza. Nayi mtengo wofunikira woti muwuze: mphamvu yodziwika bwino ya wokamba wosankhidwa iyenera kukhala katatu kuposa kuwerengera kwamalingaliro.
2. Mphamvu yokweza: poyerekeza ndi mphamvu yokweza ya transistor, mphamvu yosungira yomwe ikufunika ndi yosiyana. Izi zili choncho chifukwa chakuti curve yodzaza ya chubu amplifier ndi yosalala. Pa nsonga ya chizindikiro cha nyimbo chodzaza, chubu amplifier sichimachititsa kuti mafunde odulira azitha kusinthasintha, koma chimapangitsa nsonga ya nsonga kukhala yozungulira. Izi ndi zomwe nthawi zambiri timatcha kuti flexible shearing peaks. Pambuyo pa transistor power amplifier pamalo odzaza, kusokonekera kwa nonlinear kumawonjezeka mwachangu, zomwe zimapangitsa kuti mafunde azitha kudula kwambiri chizindikirocho. Sichimazungulira nsonga, koma chimachiyeretsa bwino. Anthu ena amagwiritsa ntchito compound impedance ya resistance, inductance ndi capacitance kuti ayerekezere loudspeaker, ndikuyesa mphamvu yeniyeni yotulutsa ya mitundu ingapo ya ma transistor power amplifier apamwamba kwambiri. Zotsatira zake zikuwonetsa kuti pamene katundu ali ndi gawo losintha, pamakhala mphamvu yokweza ya 100W, ndipo mphamvu yeniyeni yotulutsa ndi 5W yokha pamene kusokonekera ndi 1%! Chifukwa chake, kusankha kuchuluka kwa mphamvu yosungira ya transistor power amplifier:
Chokulitsa chapamwamba kwambiri: nthawi 10
Amplifier yamphamvu yapamwamba kwambiri ya boma: nthawi 6
Amplifier yamphamvu yapakatikati yapakati: katatu kapena kanayi
Chojambulira mphamvu cha chubu chingakhale chochepa kwambiri kuposa chiŵerengero chomwe chili pamwambapa.
3. Kodi pali malire angati omwe ayenera kutsala pamlingo wapakati wa kupanikizika kwa mawu ndi kuchuluka kwa kupanikizika kwa mawu pamakina. Izi ziyenera kutengera zomwe zili mu pulogalamu yowulutsa ndi malo ogwirira ntchito. 10dB yocheperako iyi, ya nyimbo zamakono za pop, kulumpha kwa bungee ndi nyimbo zina, iyenera kusiya kuchulukira kwa 20 ~ 25dB, kuti makina amawu azigwira ntchito bwino komanso mosalekeza.

Chojambulira cha Cinema cha 5.1/7.1
