Izakhi zomsindo zingahlukaniswa zihlukaniswe ngomthombo womsindo (umthombo wesiginali) ingxenye, ingxenye ye-amplifier yamandla kanye nengxenye yesipika evela kwihadiwe.

Umthombo we-Audio: Umthombo womsindo uyingxenye yomthombo yohlelo lomsindo, lapho kuvela khona umsindo wokugcina wesipika. Imithombo evamile yomsindo yile: Abadlali be-CD, abadlali be-LP vinyl, abadlali bedijithali, ama-radio ama-terhers namanye amadivayisi wokudlala alalelwayo. Lawa madivaysi aguqula noma anciphise amasiginali omsindo ezitolo zemidiya noma eziteshini zomsakazo eziteshini ze-analog ezilalelwayo ngokusebenzisa ukuguqulwa kwedijithali-kuya kokukhishwa.

I-Power Amplifier: I-Amplifier yamandla ingahlukaniswa esigabeni sangaphambili nangemuva. I-Front-Stage yangemuva kwesiginali evela kumthombo olalelwayo, kufaka phakathi kepha ayikhawulwanga ekushintsheni kokufaka, ukukhuliswa kokuqala, ukulungiswa kwethoni neminye imisebenzi. Inhloso yayo eyinhloko ukwenza umphumela wokukhishwa komthombo womsindo kanye nokuvikelwa kokufakwa kwesiteji esingemuva kufana nokunciphisa ukuhlanekezela, kepha isigaba sangaphambili akusona isixhumanisi esidingekayo ngokuphelele. Isiteji esingemuva ukukhulisa amandla okukhishwa kwesiginali ngesigaba sangaphambili noma umthombo womsindo wokushayela uhlelo lwezwi ukuze ukhiphe umsindo.

I-LoutrisPer Isiginali yomsindo esikhulisiwe samandla ishukumisela isigaxa sephepha noma i-diaphragm nge-electromagnetic, piezoelectric noma imiphumela kagesi ukushayela umoya ozungezile ukwenza umsindo. Isipika siyisiginali salo lonke uhlelo lomsindo.
