Iwo odhiyo gudzazwi chishandiso chinogadzira zvakare yekuisa odhiyo chiratidzo pane chinobuda chinhu chinogadzira ruzha. Iyo yakagadziriswazve chiratidzo vhoriyamu uye nhanho yemagetsi inofanirwa kunge iri yechokwadi-yechokwadi, inoshanda uye yakadzika kusarurama. Iyo odhiyo renji ingangoita 20Hz kusvika 20000Hz, saka gudzazwi inofanirwa kuve nemhinduro yakanaka ye frequency mune ino nhanho (idiki kana uchityaira frequency-isingatauri mutauri, senge woofer kana tweeter). Zvichienderana nechishandiso, iro simba remagetsi rinosiyana zvakanyanya, kubva pa milliwatt level ye headphones kusvika kune akati wandei TV kana PC odhiyo, kusvika makumi emawati e "mini" imba stereo uye mota odhiyo, kune yakasimba imba uye yekutengesa odhiyo. Iyo system’mazana emawatts akakwana zvakakwana kuzadzisa zvinodikanwa zveruzha rweiyo cinema kana odhitoriyamu

Audio gudzazwi ndechimwe chezvinhu zvakakosha zvezvinhu zvemultimedia uye zvinoshandiswa zvakanyanya mumunda wevatengi zvemagetsi. Linear odhiyo emagetsi anowedzera anogara achitonga echinyakare odhiyo gudzazwi musika nekuda kwekukanganisa kwavo kwakadzika uye mhando yakanaka yekurira. Mumakore achangopfuura, nekufambiswa kwemidziyo inotakurika yemultimedia yakadai seMP3, PDA, nharembozha, uye makomputa emabhuku, kugona uye huwandu hwemagetsi emagetsi akange asingakwanise kusangana nezvinodiwa mumusika, nepo maDhigirii emagetsi eChikamu D achiwedzera uye nekuwedzera inozivikanwa nekugona kwavo kwepamusoro uye saizi diki. Nyasha. Naizvozvo, epamusoro-mashandiro eKirasi D magetsi anowedzera ane kukosha kwakakosha kwekushandisa uye tarisiro yemusika.

Iko kuvandudzwa kweaudio amplifiers akasangana nematatu eras: elektroni chubhu (yekutsiva chubhu), bipolar transistor, uye munda mhedzisiro chubhu. Iyo chubhu odhiyo gudzazwi ine mellow kurira, asi iri yakawanda, yakanyanya simba yekushandisa, isina kugadzikana zvakanyanya, uye isina kunaka yakakwira-frequency mhinduro; bipolar transistor odhiyo gudzazwi ine yakafara frequency bhendi, hombe simba renji, kuvimbika kwakakwirira, hupenyu hwakareba, uye yakakwira frequency mhinduro Yakanaka, asi iyo yakasimba static simba rekushandisa uye ne-yekudzivirira yakakura kwazvo, uye kugona kwacho kunonetsa kugadzirisa; iyo FET odhiyo gudzazwi ine yakafanana mellow toni seyeyemagetsi chubhu, uye yayo ine simba renji yakafara, uye zvinotonyanya kukosha, yayo-yekudzivirira idiki, Inogona kuwana kugona kwakanyanya.
