Uyini umamukeli

Receiver - kuba amplifier multi-channel ngoba kulungiswa isiqophi digital nemifudlana umsindo. isicelo Main: I-okhulisa umsindo, ifunda e ekhaya yaseshashalazini izinhlelo. I umamukeli Useke wadlula ukuzalwa kwaso kwezobuchwepheshe eko ngasekupheleni kwekhulu lamashumi amabili, lapho umsakazo yayina kakhulu.

Yini iyisamukeli nalokho wayefana esikhathini sokuthuthuka? Ixhunyiwe ku omunye umamukeli umsakazo kanye ne-amplifier ibizwa ngokuthi "umamukeli", okuyinto uhumusha njengoba "umamukeli". Anakho ukuthandwa okukhulu phakathi bomculo, ukulalela ukusebenza bukhoma abaculi abawuthandayo ngentshiseko, ukulinda bekungeke ukukhulula ibalula ezintsha.

Phakathi ukuthuthukiswa izikhulumi yasekhaya, wathola ukusetshenziswa entsha. Okokuqala, kwaqala ukwengeza izilimi elula, okuvumela ukuba zisebenze nalawo isignali alalelwayo, unezela ivolumu umphumela futhi kamuva isiqophi esephepheni. Lokhu ngcono kakhulu izinga kokusakaza. Ukuthuthukiswa ukuqopha multi-channel umsindo ithrekhi. Lokhu kuyadingeka ukuze ngokushesha othuthukayo ifilimu umkhakha Idinga ngokuya umsindo wekhwalithi ephezulu.

Yini iyisamukeli futhi izimiso zalo zisebenza ayisebenzisayo? Ukuthola umphumela echo, umbukeli wokuqala ozwa umsindo ivela esibukweni, futhi emva kwesikhathi esithize (ukubambezeleka) has umsindo walo umboza izinhlangothi bese udonga lwangemuva ebhayisikobho. Konke lokhu msebenzi futhi eyisola umamukeli.

Omunye Onjiniyela izinto ezintsha isibe Dolby Laboratory. ekushintsheni Ngokuphelele izimiso komsindo ithrekhi okuqoshiwe, ukuqala ukurekhoda umsindo ngesimo matrix zezibalo, ikhodi it stereo emibili kuya kwemine iziteshi (futhi kamuva ezinhlanu, futhi eziyisishiyagalombili). Ukuze uthole ukusatshalaliswa efanele idatha yomsindo kuya umamukeli wakhela decoders, futhi imodeli yayo Ushintshe ngokuthi AV-umamukeli. Receiver yevidiyo ukucutshungulwa, tsifruya Imininingwane ku ukusakaza okukodwa, ukulibopha kanye amaphakethe yokudlulisela.

Yini iyisamukeli futhi lihluke kanjani amplifier evamile yomsindo? Ngokuvamile amplifier has ezimbili kuphela imigudu okhulisa, kuyilapho AV-Receiver - engaphezu kwemibili. Lezi zindlela zikholelwa uxhumano isipika iziteshi emaphakathi, kwesokunxele nakwesokudla, kwesokunxele kanye neziteshi kwesokudla ozungezayo. Kubukeka sengathi uhlelo a 5.1 umamukeli.

Receiver 7.1 isivele iziteshi ezimbili kwesokunxele bese ozungezayo kwesokudla. Digital eyodwa isiteshi isifinyezo imelela ongaphakeme imvamisa ububanzi. Isignali sidla kuya subwoofer, kodwa inzuzo yale umamukeli isiteshi asisho ukukhiqiza, kusukela isignali lwento ezingeni okukhiphayo.

Indlela ukukhetha umamukeli hhayi abanjwe? Okokuqala, kubalulekile ukuba sithole amandla wazifunela okhulisa. Kodwa umbuzo uwukuthi, kunalokho, umuntu, akusiyo ekubuyekezweni. Njengoba isisho sibonisa: "Kungakhathaliseki ukuthi kuningi kangakanani ukuthatha ke, kusenzima akwanele." Isici esibaluleke kakhulu okufanele ukuba unake - lena ukuqinisa transformer umsindo. Kungcono ukuthenga umamukeli nge transformer toroidal. Ivame abolekise amandla esikhulu ziqhathaniswa isixazululo bendzabuko ngaphansi Ubukhulu efanayo. It is hhayi njengoba kakhulu ukufuthelana phakathi ukusebenza.

Kukhona ngokuqhubekayo futhi izifunda okuhlangene kutsi bakwati kutakhela umamukeli. wesifunda leyehlukene siqukethe transistors futhi aqiniswe chips nalolwakheke kahle. Ukwakhiwa i wesifunda okuhlangene ziphansi ekupheleni amamodeli abamukelayo ngendlela nemfashini, isinqumo ultra-nomzimba omncane. Muva nje, funa digital tuners TV zinezikhathi amandla okusezingeni eliphezulu, esibonakalayo enembile kanye ukucushwa lula ngqo kusuka control panel. Lapho ukhetha ukuthi omkhulu kunani ukunakwa kukhokhelwe uxhumano ezikhumulweni nge izikhulumi. Kuyinto efiselekayo ukuthi kube isikulufa, kanjalo ekuthuthukiseni kakhulu izinga sound.

AV-umamukeli has a isethi esezingeni AV-ukuqala kanye Imiphumela. Isekela umsindo analog, alalelwayo digital, S-vidiyo, SCART, Yocezuningi, isiqophi ingxenye, isiqophi oluyinhlanganisela. XLR isixhumi isetshenziswa kuphela ephezulu onobuhle.

Kukhona futhi abamukelayo ezikhethekile ngoba zvukoobrabotki professional, kodwa ukuchaza nabo isihloko ngalokho owamukelayo akwenzi mqondo. Izakhamuzi Simple ngabe bayehluleka ngekwetimali hhayi siyatlhogeka ngebanga ukusebenza ozinikele futhi kusadingeka.
