Ruzha amplifier ita iwe pachako

Takatenga laptop yakanaka kana foni inotonhorera, tinofara nekutenga, kuyemura seti yezvinhu uye kumhanya kwechinhu. Asi zvakafanira kubatanidza gadget kune vatauri kuti vateerere mimhanzi kana kuona bhaisikopo, tinonzwisisa kuti ruzha runogadzirwa nemudziyo, sezvavanotaura ". Panzvimbo pekunaka kwakazara uye kwakachena, tinonzwa hunyanzvi hwekuzevezera nerombo remashure.

Asi usagumbuka uye utsinye vagadziri, dambudziko nerinogona kugadziriswa wega. Kana iwe uchinzwisisa machipisi uye uzive nzira yekutengesa zvakanaka, hauzove wakaoma kuita yako amplifier ruzha. Mune chinyorwa chedu, isu tichaudza maitiro ekuita ruzha rwekumira kune imwe neimwe yemhando yemushini.

Maitiro Ekuita Inzwi Anfoifier?

Pazororo rekutanga rebasa pakugadzira amplifier, iwe unofanirwa kutsvaga maturusi uye kutenga zvikamu zvikamu. Dunhu reAmplifier rakagadzirwa pane rakadhindwa redunhu redunhu netirongo. Kugadzira machipisi, shandisa matenga akakosha ekutengesa anogona kutengwa muchitoro. Uchishandisa dunhu rakadhindwa rinotendera kuti uite mudziyo compact uye nyore kushanda.

Amplifier inonzwika frequency

Usakanganwa nezvezvinhu zvekufananidza single-chiteshi amplifiers zvichienderana neiyo chip yeTDA Series, iyo huru yeiyo kugoverwa kwehuwandu hwekupisa. Naizvozvo, edza nemukati mhepo yeAmplifier, kunze kwemicrocircuit kusangana nezvimwe zvikamu. Zvekuwedzera kutonhorera kweAmplifier, inokurudzirwa kushandisa radiator latties yekupisa kubvisa. Iyo grid saizi inotsamira pamuenzaniso weiyo chip uye simba reAmplifier. Isa iyo nzvimbo yekupisa ichinyura mukati meiyo Amplifier dzimba.

Chimwe chinhu chekugadzira yakazvimirira yeiyo inonzwika amplifier yakaderera simba rekushandisa. Izvi zvinokutendera kuti ushandise iyo amplifier mumotokari nekuibatanidza iyo bhatiri kana munzira uchishandisa simba rekubatira. Rakarerutsirwa Amplifier Models Anoda Voltage yezvino chete mu3 volts.

Zvinhu zvikuru zve amplifier

Kana iwe uri kutanga radio amateur, saka kune rimwe basa rakakodzera, tinokurudzira kuti ushandise chirongwa chakakosha chekombuta - Sprint marongero. Nechirongwa ichi iwe unogona kugadzira uye kutarisa schamas pakombuta yako. Ziva kuti kusikwa kwezvirongwa zvako zvine musoro, chete mune izvo zviitiko kana uine ruzivo rwakakwana uye ruzivo. Kana iwe uri asina ruzivo redhiyo amateur, wobva washandisa madhiri akagadzirwa uye akagadziridzwa.

Pazasi isu tichapa zano uye tsananguro dzezvisarudzo zvakasiyana zveOrplifier:

Healphone inoratidzika amplifier

Inzwi ramplifier yemisoro inotakurika haina simba rakakwirira, asi rinodya simba shoma. Ichi chinhu chakakosha kune mbozhanhare amplifiers iyo inopa mabhatiri. Zvakare pane mudziyo unogona kuiswa kuumbwa, kune simba kubva kune network kuburikidza ne3 volt adapta.
