Zingaphi Iziteshi Ezifunekayo kwiStereo Yakho yasekhaya yaseStereo?
Kanye kunye nezithethi, abafumana i-receiver bakha inxalenye yeenkqubo ezininzi ze-stereo zasekhaya. Ukunikezelwa kwenani lezinketho ezifumanekayo - iziteshi ngokukhethekileyo - omnye unokushiywa ebuza ukuba yiyiphi into eyoyikhethayo. Ngokuqinisekileyo konke kuya kwelo hlobo lomxholo oceba ukuzonwabisa kunye nenqanaba lokoqobo ofuna ukulufumana. Ukufumana izithethi ezongezelelweyo ukuxhasa i -receiver multi-channel (receiver multi-channel receiver) akufanele ukuba ixabiso xa unamathela kwisicwangciso kunye nohlahlo lwabiwo-mali . Ngoko nantsi ukuphazamiseka koko zonke iziteshi ezongezelelweyo zithetha.
I-2.0 kunye ne-2.1 yeStereo Systems Systems
Isistim sakho esisisiseko se-stereo (2.0) siqukethe iziteshi ezimbini zesandi - esisele nangesokudla-eziveliswe yizibini zezithethi ze-stereo. Uninzi lwezivakalisi lunikwe amandla ngumntu owamkelayo (okanye nakwi-amplifier enhle ), nangona ezinye zangoku zinokudlulela imfuneko yeso sixhobo ngeempawu ezingaphezulu kunye / okanye ukuxhumeka kwentambo. Inkqubo yesiteshi se-2.1 ifumaneka ngokukhawuleza nje xa ufaka i-subwoofer ehlukeneyo ( inxenye ye-surround sound ) kunye nezithethi ze-stereo. Iintlobo zokukhetha i-2.0 okanye 2.1 inkqubo yesitya ilula lula. Unokonwabela umsindo omnandi kumabonakude, iifilimu, kunye neTV ngaphandle kokubamba izithethi ezongezelelweyo kunye neencingo ezivame ukuza nazo. Kodwa ukuba i-truer ijikeleze amava aphilileyo yintoni olandelayo, uya kufuna okungaphezulu kwesibini seentetho.
5.1 Iiseshoni zeeKhaya zoTywala zasekhaya
Abamkeli bemidlalo yasesekhaya bahluke kwiimpawu zecandelo ezimbini (i-receiver stereo) ngokufumana iziteshi ezongezelelweyo ze-amplifier ukuxhasa isandi semidlalo yee-movie (isib. I-Dolby Digital 5.1, i-DTS 5.1) okanye umculo womda weqela (umzekelo, iDVD-Audio , i- SACD disks). Isistim sakho esisiseko senkundla yemidlalo unikeza iziteshi ezi-5.1 zesandi ngeentetho ezi-5 ezahlukeneyo kunye ne-subwoofer enye. Njengendlela yesitishi ezimbini, izithethi ezisekhohlo nezilungileyo zenza loo mqondiso ulwalathiso kwaye idlala ininzi yesenzo esikwi-screen. Isithethi sesikhungo ngokuqhelekileyo sigcinwe kwingxoxo yencoko ye-movie, imisindo yomculo kunye nezandi ezisekelayo. Izitishi ezijikelezayo / ezisekunene / ezisezantsi zinceda ukunika ubungakanani bomhlaba ngokuzidlala ngokuzenzekelayo kunye neempembelelo ezizodwa. Isiteshi se-subwoofer (esaziwa ngokuba yi-Low-Frequency Effects, okanye i-LFE) sineziseko eziphantsi kakhulu kwimithombo yomculo kunye nemiphumo ekhethekileyo kwii-soundtracks. Ngokubambisana, zonke iziteshi zivelisa "i-soundfield" evulela umphulaphuli ngesandi esivela phambili nangasemva.
6.1 Iinkqubo zeeKhaya zoLondolozo lwaseKhaya
Yonke inkqubo yesiteshi se-6.1 inikezela ngaphaya kwe-5.1 yesinye isithethi esinye. Ngokufakwe kwinqanaba elingemuva, uqukumbela ngeentetho ezintathu phambi, ezimbini zijikelezileyo, kwaye enye iyazinikela emva (kunye ne-subwoofer). Kwabanye, esi sithethi esongezelelweyo asifanelekanga imali, indawo kunye nomgudu wokufaka. Kodwa ukuba ufuna ukufumana ubukhulu obungakumbi, isithethi sangasese sangasemva sinceda ukudala indawo ecacileyo kunye nokucinga kwezandi. Imiphumo yesandi eshukumisayo, efana nezithuthi ezidlulayo, amazwi, okanye iibhola ezithwala phezulu, ziya kubonakala zichanekile kwaye zichazwe ngendlela yeseshoni ye-6.1. Nangona kunjalo, kufuneka uqinisekise ukuba umxholo womthombo ukhutshelwe ukuxhasa olu hlobo lokudlala (umz. Dolby Digital EX, iDTS-ES).
7.1 Iiseshoni zeeKhaya zoLondolozo lwaseKhaya
Ngokufana nendlela i-6.1 iphakanyiswa ngayo ukusuka kwinkqubo yesiteshi se-5.1, ummkeli wesiteshi se-7.1 ungeze esinye isithethi kumxube. Ngoko uza kuba neendlela ezintathu eziphambili, iziteshi ezimbini ezijikelezayo, kunye neziteshi ezimbini zangemva (kunye ne-subwoofer). Ingaba isithethi esingaphezulu, isithethi sangasemva senza impembelelo ebalulekileyo ekumiselweni kwezandi kunye nemiphumo engqongileyo? Impendulo inokuxhomekeka kwindlela ovuyayo ngayo loo nto ekholisayo, njenge-movie efana neyakho ekhaya. Abamkeli bee-7.1 ezininzi banikela nge-THX ™ yokuphucula izandi. Ephuhliswe nguLucas Film ™ kwaye ilungiselelwe iifilimu kunye nomculo weziteshi ezininzi, ukucwangciswa kwe-THX yenzelwe ukubonisa i-movie / umculo womculo ngekhwalithi echanileyo. Unokufumana ezinye iiprogram ze-soundfield, ezifana ne-Sony Digital Digital Cinema Sound ™ okanye iChimema ye-DSP ™ ye-Yamaha. Nangona kunokuba ngumngeni ukuma nokucoca i-system ye-7.1 yesistim, iziphumo ziya kubaluleka kulabo abafuni nto engaphantsi kweyona nto ibhetele.
