Iyo yakasanganiswa odhiyo simba gudzazwi inonzi seyakagadzwa kubudirira. Basa reiyo inosanganisa gudzazwi ndeyekusimudzira simba rechidimbu chemagetsi chisina kusimba chinotumirwa nedunhu repamberi, uye nekugadzira yakakura yakakwana yazvino kutyaira mutauri kuti apedze shanduko ye electro-acoustic. Iyo inosanganisa gudzazwi inowanzoshandiswa mune dzakasiyana odhiyo simba gudzazwi maseketi nekuda kwayo yakapfava payo wedunhu uye inokodzera kugadzirisa dambudziko.

Seti dzinowanzo shandiswa dzinosanganisira LM386, TDA2030, LM1875, LM3886 uye mamwe mamodheru. Iko kuburitsa simba reiyo yakasanganiswa gudzazwi inosvika kubva kumazana emamiriseti (mW) kusvika kumazana emawati (W). Zvinoenderana nesimba rekuburitsa, inogona kukamurwa kuita zvidiki, zvepakati uye zvine simba magetsi. zvinoenderana nechinzvimbo chinoshanda cheiyo gudzazwi remagetsi, inogona kukamurwa kuita Chikamu A (A Kirasi), Kirasi B (Kirasi B), Kirasi A uye B (Kirasi AB), Kirasi C (Kirasi C) uye Kirasi D (Kirasi D). Kirasi A emagetsi zvinowedzera zvine diki kumonyanisa, asi yakaderera kushanda, ingangoita 50%, uye rakakura simba kurasikirwa. Ivo anowanzo shandiswa mune yekumusoro-kumagumo imba midziyo yemagetsi. Makirasi B masimba anowedzera zvine hunyanzvi hwepamusoro, angangoita 78%, asi chinokanganisa ndechekuti ivo vanowanzo kukanganisa kukanganisa. Magadzirirwo ekirasi A uye B ane zvakanakira kunaka kweruzha uye kugona kwakanyanya kweClass A amplifiers, uye anoshandiswa zvakanyanya mudzimba, nyanzvi, uye mota odhiyo masystem. Kune mashoma Class C magetsi anowedzera simba nekuti isimba rekuwedzera rine rakanyanya kukanganisa, iro rinokodzera chete kune zvinangwa zvekutaurirana. Kirasi D odhiyo simba gudzazwi inonziwo dhijitari simba gudzazwi. Kubatsira kwacho ndekwekuti kugona ndiko kwakanyanya, magetsi anogona kuderedzwa, uye panenge pasina kupisa unogadzirwa. Naizvozvo, hapana chikonzero cheredhiyo hombe. Iyo vhoriyamu uye mhando yemuviri yakaderedzwa zvakanyanya. Mune dzidziso, kukanganisa kwacho kwakaderera uye kuenzana kwakanaka. Basa rerudzi urwu rwemagetsi gudzazwi rakaomarara, uye mutengo hausi wakachipa.

Simba gudzazwi rinodaidzwa kunzi gudzazwi remagetsi kwenguva pfupi, uye chinangwa chayo ndechekupa mutoro neakakura akakwana azvino dhiraivha kugona kuzadzisa simba. Kirasi D simba gudzazwi rinoshanda mune ye-off state. Mune dzidziso, haidi quiescent yazvino uye ine hunyanzvi hwekuita.

Iyo sine wave odhiyo yekuisa chiratidzo chiratidzo uye netriangular wave chiratidzo ine yakanyanya kuwanda frequency inogadziriswa nemuenzanisi kuti awane PWM modulation chiratidzo chine basa rebasa rakaenzana nehukuru hwechiratidzo chekuisa. Iyo PWM modulation chiratidzo inotyaira kuburitsa simba chubhu kuti ishande mune ye-off state. Mhedzisiro yekuburitsa chubhu inowana chiratidzo chekuburitsa neyakagara basa kutenderera. Iko kukura kwechiratidzo chekuburitsa imagetsi emagetsi uye ine simba razvino rekutyaira kugona. Mushure mekushomeka kwechiratidzo, chiratidzo chekuburitsa chine zvese chiratidzo chekuisa uye izvo zvakakosha zvikamu zveiyo modular triangle wave, pamwe neayo akakwirisa maumboni uye musanganiswa wavo. Mushure meLC yakaderera-kupasa kusefa, iyo yepamusoro-frequency zvikamu mune yekuburitsa chiratidzo inosvinwa kunze, uye yakaderera-frequency chiratidzo ine yakafanana frequency uye amplitude seyekutanga odhiyo chiratidzo chinowanikwa pane iwo mutoro.
