Makina ophatikizira amawu amawu amatchedwa kupambana bwino. Ntchito ya amplifier yophatikizira ndikukulitsa mphamvu ya siginidwe yamagetsi yofooka yomwe imatumizidwa ndi gawo loyang'ana kutsogolo, ndikupanga mpata waukulu wokwanira kuyendetsa wokamba nkhani kuti amalize kutembenuka kwamagetsi. Mkuzamawu Integrated chimagwiritsidwa ntchito mu madera osiyanasiyana Audio mphamvu mkuzamawu chifukwa cha dera ake yosavuta zotumphukira ndi debugging yabwino.

Maseti omwe amagwiritsidwa ntchito nthawi zambiri amakhala LM386, TDA2030, LM1875, LM3886 ndi mitundu ina. Mphamvu yotulutsa yama amplifier ophatikizika amachokera ku milliwatts (mW) mpaka mazana a watts (W). Malinga ndi mphamvu yotulutsa, imatha kugawidwa m'magulu ang'onoang'ono, apakatikati komanso okwera mphamvu; malinga ndi momwe ntchito imagwirira ntchito chubu yamagetsi yamagetsi, itha kugawidwa m'magulu A (A Class), Class B (Class B), Class A ndi B (Class AB), Class C (Class C) ndi Class D (Class D). Ma amplifiers amagetsi a Class A ali ndi zosokoneza pang'ono, koma magwiridwe antchito otsika, pafupifupi 50%, ndikuwonongeka kwakukulu kwamagetsi. Nthawi zambiri amagwiritsidwa ntchito pazida zapanyumba zapamwamba. Ma amplifiers amagetsi a Class B ali ndi magwiridwe antchito apamwamba, pafupifupi 78%, koma choyipa ndichakuti amakonda kupotoza crossover. Ma amplifiers a Class A ndi B ali ndi zabwino zamawu amawu abwino komanso magwiridwe antchito apamwamba a Class A, ndipo amagwiritsidwa ntchito kwambiri munyumba, akatswiri, komanso machitidwe amawu pagalimoto. Pali ma amplifiers ochepa a Class C chifukwa ndimphamvu yamagetsi yokhala ndi zosokoneza kwambiri, zomwe ndizoyenera kulumikizana zokha. Mphamvu yamagetsi yamagetsi ya Class D imatchedwanso digito yamagetsi yamagetsi. Ubwino ndikuti magwiridwe antchito ndiye apamwamba kwambiri, magetsi akhoza kuchepetsedwa, ndipo pafupifupi kutentha konse kumapangidwa. Chifukwa chake, palibe chifukwa chojambulira chachikulu. Mphamvu ndi thupi zimachepetsedwa kwambiri. Mwachidziwitso, kupotoza ndikotsika ndipo mzere wake ndi wabwino. Ntchito yamphamvu yamagetsi yamtunduwu ndiyovuta, ndipo mtengo wake siotsika mtengo.

Chowonjezera mphamvu chimatchedwa chopangira mphamvu mwachidule, ndipo cholinga chake ndikupatsa katunduyo mphamvu yayikulu yokwanira pakadali pano kuti akwaniritse mphamvu yamagetsi. Mphamvu D yama amplifier imagwira ntchito yolemera. Mwachidziwitso, sizikusoweka momwe ziliri pakali pano komanso zimakhala ndi magwiridwe antchito.

Chizindikiro cholozera cha sine wave ndi ma triangular wave wave okhala ndi pafupipafupi kwambiri amasinthidwa ndi kufananizira kuti atenge chizindikiro cha PWM chosinthira chomwe ntchito yake ndiyofanana ndi matalikidwe a chizindikirocho. Chizindikiro cha PWM chosinthira chimayendetsa chubu yamagetsi yotulutsa kuti igwire ntchito yolemetsa. Mapeto ake a chubu amalandila chizindikiritso chokhazikika pantchito. Matalikidwe a chizindikirocho ndi magetsi amagetsi ndipo ali ndi kuthekera kwamphamvu kwakanthawi koyendetsa. Pambuyo pakusinthasintha kwa ma siginolo, chizindikirocho chimakhala ndi mayendedwe olowera komanso zinthu zofunika kwambiri pakapangidwe kazithunzithunzi, komanso ma harmoniki awo apamwamba ndi kuphatikiza kwawo. Pambuyo pa kusefera kwa LC kotsika, zida zamafupipafupi mu chizindikirocho zimasefedwa, komanso chizindikiritso chotsika kwambiri chomwe chimafanana ndi matalikidwe ofanana ndi momwe mawu amawu oyamba amapezekera pamtolo.
