Yintoni na umlinganiseli

Lo ufumana - yinto msindo multi-umjelo zokucazulula yevidiyo yedijithali kunye nemisinga odiyo. isicelo Main: ngokuba yokukhulisa, abawacazululayo kwiinkqubo yeqonga ekhaya. Umamkeli kuphunyeziwe ukuzalwa yayo zobugcisa kwi eko kade zenkulungwane yamashumi amabini, xa unomathotholo ifikelele incopho yayo.

Yintoni na umlinganiseli noko wayefana kwisithuba yophuhliso lwayo? Xhume kwenye radio and msindo ubizwa ngokuba "yofumana ulwazi", bona bubonakala "receiver". Uphethe kuthandwa kakhulu phakathi music fans, ngentumekelelo ukuphulaphula imidlalo ubomi amagcisa zabo abazithandayo, yaye elinde liya kukhupha singles ezintsha.

Ngexesha uphuhliso ezithethi zasekhaya, wafumana ukusetyenziswa entsha. Okokuqala, kwaqala ukongeza iziqhubekisi elula, ukuvumela ukuba ukusebenza kunye uphawu audio, ukudibanisa isiphumo umthamo kunye iikhowudi ividiyo kamva. Oku kwaphucula kakhulu umgangatho zosasazo. Uphuhliso zokurekhodisha multi-channel sound track. Oku kufunelwa ushishino umboniso olukhula ngokukhawuleza ifuna ngokwandileyo isandi ezikumgangatho ophezulu.

Yintoni na umlinganiseli kunye nemigaqo yayo isebenza? Ukufumana iziphumo echo, umbukeli uve isandi evela ikhusi, kwaye emva kwexesha elithile (ukulibaziseka) iye isandi yayo ziqina emacaleni nodonga elingasemva cinema. Wonke lo msebenzi aze akwamkele.

Enye kubabhekisi phambili be izinto ezintsha iye Dolby Laboratory. Ngokupheleleyo ukutshintsha imigaqo ingoma oqo-, ukuqala ukurekhoda isandi ngokohlobo matrix zezibalo, ujiko ukuba amajelo a stereo ezimbini ukuya kwezine (yaye kamva ezintlanu, kwaye ezisibhozo). Kuba unikezelo olululo lwedata evakalayo ukuya ngumamkeli waqala ukwakha STB, kunye nohlobo kancincane ekuthiwa AV-receiver. Receiver ukugaywa yevidiyo, tsifruya iinkcukacha umsinga mnye, Oluma kwaye kubobonke usulelo.

Yintoni na umlinganiseli nendlela iyahluka ukusuka msindo yesiqhelo umsindo? Ngokwesiqhelo lo mshini iye imijelo ezimbini kuphela sufaka, lo gama i-AV-Receiver - ngaphezu ezimbini. Zikholelwa ukuba udibaniso isithethi ndlela esembindini, ekhohlo ne ekunene, ekhohlo kunye nemijelo bayawarhawula tye. Kubonakala ngathi le nkqubo a 5.1 receiver.

Umfumani 7.1 sele iindlela ezimbini ekhohlo kwaye bayawarhawula ekunene. Digital enye kwezinye basisishunqulelo imela kwasezantsi frequency. Uphawu kondliwa ngawo subwoofer, kodwa inzuzo yalo receiver siteshi ongavelisi, ekubeni uphawu lwento ukuya kwinqanaba kwimveliso.

Indlela ukukhetha akwamkele kwaye hayi ukuba abanjwe? Okokuqala, kuyimfuneko ukumisela umthamo ofunekayo okhulisa. Kodwa ke umbuzo, kunoko, umntu ngamnye, akukho kuhlelwa ngokutsha. Njengoko isisho: "Kungakhathaliseki kangakanani makayithabathe, kusesemini akwanelanga." Eyona nkalo ibalulekileyo kufuneka sinikele ingqalelo - oku kugunyaziso transformer isandi. Kungcono ukuba athenge ne sombane toroidal. Oku kudla zalikhupha igunya enkulu xa kuthelekiswa isisombululo bemveli phantsi imilinganiselo efanayo. It is hhayi liyavutha ngamandla ngexesha lokusebenza.

Kukho ezahlukene kunye neziphaluka ezihlangeneyo yokwakha receiver. ukujikeleza ezahlukene ibandakanya transistors nemanyaneyo chips yakhiwe. Ukwakhiwa an integrated zeesekethe imizekelo ekupheleni esezantsi baze abanye balwamkele kwi, isigqibo ezithandwayo ultra-obhityileyo. Kutshanje, imfuno yedijithali tuners TV luphawulwa ngamandla aphezulu, esibonakalayo enobuchule kunye uqwalaselo lula ngqo kwiqela lenjongo control. Xa ukhetha eninzi ingqalelo ihlawulwe kwiitheminali uqhagamshelwano kunye nezithethi. Kunqweneleka ukuba babe esijijwayo, ngako oko kuqiniswe kakhulu umgangatho isandi.

AV-umyalezo unesethi esemgangathweni AV-amagalelo kunye neziphumo. Ixhasa audio analog, odiyo digital, S-video, SCART, uqhagamshelwano lwetshiphu emsebenzi, icandelwana ividiyo, ividiyo edityanisiweyo. XLR isinxibelelanisi isetyenziswa kuphela imizekelo ekupheleni ophezulu.

Kukwakho balwamkele ezizodwa ngenxa zvukoobrabotki umsebenzi, kodwa ukuchaza ngendlela inqaku ngoko lowo akwenzi ngqiqo. abemi alula lungafikeleleki nje kwaye hayi kwakufuneka ngenxa ukusebenza abazinikeleyo emsebenzini.
