Imuphi Umamukeli Wezakhiwo Zekhaya Elingcono Kuwe?
Umbuzo owodwa wendawo yaseshashalazini oceliwe kaningi uma ngabe umamukeli wesiteshi sekhaya wesiteshi se-5.1 noma 7.1 kungcono.
Kuvela ukuthi kokubili okukhethwa kukho kunenzuzo nezinsalela, kuye ngokuthi yiziphi izingxenye zomthombo oyisebenzisayo, zingaki izikhulumi ofuna ukuyisebenzisa, nokuthi yiziphi izintandokazi zakho eziqondene nokusetha ukuguquguquka.
5.1 Isisekelo sesiteshi
Abamukeli bezeshashalazi zaseshashalazini ezingu-5.1 bebelokhu beyisilinganiso seminyaka engamashumi amabili. Banikeza isipiliyoni esihle sokulalela, ikakhulukazi ekamelweni elincane ukuya emaphakathi. Ngokwesimiso sesiteshi / isikhulumi, umamukeli wesiteshi esingu-5.1 uhlinzeka:
- Isiteshi sesiteshi sokuhlinzeka isiteji sehange sokuxoxa noma umculo womculo.
- Iziteshi zangaphambili ezingakwesokunxele nangakwesokudla ukuhlinzeka ngolwazi oluyinhloko lwe-soundtrack, noma ukukhiqizwa komculo we-stereo.
- Iziteshi ezizungezile ezingakwesokunxele nangakwesokudla zecala nangaphambili ukuya emiphumeleni yokunyakaza yangemuva evela kuma-soundtracks e-movie nasemisindo enhle esuka kokurekhoda komculo.
- Umzila we-Subwoofer, ohlinzeka ngemiphumela ephansi kakhulu, njengokungqubuzana noma ukusabela emibonweni yomculo.
7.1 Isisekelo sesiteshi
Kodwa-ke, uma uzama ukunquma uma isamukeli semidlalo yaseshashalazini yaseshashalazini engu-5.1 noma se-7.1 ikulungile kuwe, kunezici eziningana ezisebenzayo zesamukeli se-7.1 esingaba yinzuzo ongase ungayicabangi.
Iziteshi Ezengeziwe: Isistimu yesiteshi se-7.1 ifaka zonke izici zesistimu yesiteshi esingu-5.1, kodwa esikhundleni sokuhlanganisa zombili izimo zomsakazo ezizungezile nangemuva zibe iziteshi ezimbili, uhlelo lwe-7.1 luhlukanisa ulwazi oluzungezayo nolwesiteshi sangemuva emashaneli amane. Ngamanye amazwi, imiphumela yomsindo ohlangothini kanye ne-ambiance iqondiswa eziteshini ezizungezile ezingakwesokunxele nangakwesokudla, nemiphumela yangemuva yangemuva kanye ne-ambiance iqondiswa eziteshini ezimbili ezingemuva noma zangemuva ezengeziwe. Kulesi setup, izikhulumi ezizungezile zibekwe ohlangothini lwesimo sokulalela futhi iziteshi zangemuva noma zangemuva zifakwa ngemuva komlaleli.
Ukuze ubuke ukubuka umehluko phakathi kwesakhiwo sesipikha sesiteshi sesiteshi esingu-5.1 nesakhiwo sesiteshi sesiteshi se-7.1, hlola umdwebo omuhle kakhulu ohlinzekwa yi-Dolby Labs.
Isimo sokulalela esiteshini esingu-7.1 singangezelela ukujula okungaphezulu kwesipiliyoni somsindo ozungezile, sinikeze insimu yomsindo oqondile, eqondiswayo, futhi esakazekayo, ikakhulukazi emakamelweni amakhulu.
Qondanisa ukuzenzekela komsindo: Nakuba ama-DVD amaningi nama-Blu-ray Discs aqukethe ama-soundtracks angu-5.1 (kanye nalawo aqukethe ama-soundtracks angu-6.1 wesiteshi), kukhona inani elandayo lamazwibela e-Blu-ray aqukethe ulwazi lweziteshi ezingu-7.1, noma ngabe yi-PC 7.1 engavunyelwe i- PCM , I- Dolby TrueHD , noma i- DTS-HD Master Audio .
Uma une-receiver yesiteshi esingu-7.1 ne-audio input kanye nokucubungula ikhono nge-HDMI uxhumano (ungadluleli-ukuxhumana kuphela), ungasebenzisa ezinye, noma zonke lezo zikhetho zomsindo ezizungezile. Hlola imininingwane, noma incwadi yomsebenzisi, kumamukeli ngamunye wesiteshi esingu-7.1 okungenzeka ucabangele okunye okucacile kumakhono alo alalelwayo we-HDMI.
Sondeza Ukukhuliswa Kwemsindo: Futhi, ngisho nokudlala kwama-DVD ajwayelekile, uma i-DVD yakho ye-soundtrack iqukethe i- Dolby Digital noma i- DTS 5.1 noma kwezinye izimo, ama- DTS-ES 6.1 noma ama-soundtracks e-Dolby Surround EX 6.1, ungakwazi ukwandisa isipiliyoni somsindo ozungezile ku-7.1 ngokusebenzisa isandiso seDolby Pro Logic IIx noma amanye amamodi azungezile angu 7.1 DSP (Digital Sound Processing) angase atholakale kumamukeli wakho. Futhi, lezi zindlela ezingeziwe zingakhipha insimu ezungezayo yesiteshi esivela ku-7.1 kusuka kumthombo wesiteshi wesiteshi 2 okuvumela ukuthi ulalele ama-CD noma imithombo ethile ye-stereo kwifomethi ezwakalayo egcwele nxazonke.
Okunye Okuzungezile Izinketho Zomsindo: Ezinye izandiso zomsindo ozungezile ezingasebenzisa iziteshi ezingu-7.1 yi- Dolby Pro Logic IIz no- Audyssey DSX . Nokho, esikhundleni sokungeza izikhulumi ezimbili ezizungezile, i-Dolby Pro Logic IIz ne-Audyssey DSX vumela ukufakwa kwezikhulumi ezimbili zokuphakama ngaphambili. Lokhu kunikeza isiphakamiso esengeziwe sokwenza isiphakamiso. Futhi, i-Audyssey DSX inikeza nabasebenzisi ithuba, kusetha isiteshi se-7.1 ukubeka izikhulumi ezibekiwe phakathi kwezikhulumi ezizungezile nezikhulumi zangaphambili, esikhundleni sezikhulumi zokuphakama-lezi zikhulumi zibhekwa ngokuthi "izimpikiswano ezungezile".
I-Bi-Amping: Enye inketho eba yinto evamile kakhulu kumamukeli wesiteshi 7.1 yi- Bi-Amping . Uma unezikhulumi zangaphambili zesikhulumi ezinezixhumi ezihlukene zesikhulumi zokuxhumana eziphakathi kwe-midrange / tweeters kanye ne-woofers (Angikubhekiseli ku-subwoofer, kodwa ama-woofers ezikhulwini zakho zangaphambili), ezinye izamukeli zesiteshi ezingu-7.1 zivumela ukuthi ukwazi ukuphinde uphinde uthumele ama-amplifiers asebenza nge-6th kanye neziteshi ezingu-7 eziteshini zakho zangaphambili. Bese kukuvumela ukuba ugcine ukusetha okugcwele kwesiteshi 5.1, kodwa namanje, engeza iziteshi ezimbili ezengeziwe zokukhulisa ngakwesokunxele nezikhulumi zakho zangakwesokudla.
Ukusebenzisa ukuxhumeka kwezikhulumi ezihlukile zesiteshi sesi-6 nesesishiyagalombili kuzikhulumi zakho ezikwazi ukusebenzisana nama-bi-amp, ungakwazi ukuphinda kabili amandla anikezwe ngeziteshi zakho zangakwesokunxele nangesokudla. I-front-range yakho / i-tweeters iphelela ukugijima kweziteshi eziyinhloko ze-L / R kanye nama-woofers okhulumi wakho wangaphambili agijima ekuxhumaneni kwakho kwe-6 no-7 wesiteshi se-Bi-amp.
Inqubo yalolu hlobo lokusetha ichazwa futhi iboniswe emibhalweni yomsebenzisi yamamukeli amaningi wesiteshi 7.1. Kodwa-ke, njengoba ngishilo ekuqaleni, nakuba lokhu kuba yisici esivamile, kodwa asihlanganisiwe kuzo zonke izimpendulo zesiteshi 7.1.
I-Zone 2: Ngaphandle kwe-Bi-amping, iziteshi eziningi ezingu-7.1 zokuthola indawo yaseshashalazini zinikeza inketho ye-Zone 2 enikwe amandla.
Lesi sici sivumela abasebenzisi ukuthi baqalise ukusethwa kwesikhungo sendawo yaseshashalazini yasendlini ka-5.1 ekamelweni lakho eliyinhloko, kodwa, kunokuba baxube izikhulumi zakho zangaphambili, noma wengeze iziteshi ezimbili ezungezile ezungeziwe ngemuva kwesimo sokulalela, ungasebenzisa iziteshi ezimbili ezingaphezulu izikhulumi zamandla kwenye indawo (uma ungacabangi isethi sezintambo zesikhulumi eside).
Futhi, uma uthanda umqondo wokusebenzisa indawo yesibili ene-powered, kodwa namanje unesifiso sokusetha umsindo we-7.1 wesiteshi esiphezulu esiteshini sakho esikhulu, abamukelayo beziteshi ezingu-7.1 bangavumela lokhu, kodwa ungenza kokubili ngesikhathi esifanayo. Ngamanye amazwi, uma uvula i-Zone yesi-2 ngenkathi usebenzisa indawo enkulu, indawo eyinhloko ngokuzenzakalelayo iyafeza iziteshi ezingu-5.1.
Okushiwo yilokhu ukuthi, ezimweni eziningi, ngenkathi ulalele futhi ubukela ama-DVD akho kumsindo wesizungezo wesiteshi esingu-5.1 ekamelweni lakho eliyinhloko, omunye umuntu angase alalele i-CD (uma unomdlali ohlukile weCD oxhunywe kumamukeli wakho) kwelinye igumbi, ngaphandle kokuba ne-CD player kanye nesamukeli ekamelweni elithile - nje izikhulumi.
Kanti futhi, abamukeli abaningi baseshashalazini abaningi base-7.1 banikeza ukuguquguquka okwengeziwe ekusethekeni nasekusebenziseni izingxenye ezengeziwe .
9.1 iziteshi kanye nangaphezulu
Njengoba izinketho eziningi zokucubungula umsindo eziyinkimbinkimbi zitholakala, njenge- DTS Neo: X , engakwazi ukwandisa inani lamashaneli angahle akhiqizwe noma asuswe emithonjeni yomthombo, abakhiqizi bafaka i-ante ngenani leziteshi abangangena ekhaya indawo yeshashalazi yesikhombisi. Uma uhambela esiteshini se-receiver se-high-end reception hall, kukhona inombolo ekhulayo yabamukeli abanikela manje 9.1 / 9.2 nenani elincane elinikeza nezinketho zokuhlela zesiteshi 11.1 / 11/2.
Kodwa-ke, njengoba kunamamukeli wesiteshi 7.1, kungakhathaliseki ukuthi udinga 9, noma ngaphezulu, iziteshi kuxhomeke kulokho ofuna ukukufeza ekusetheleni kwakho kwasekhaya. Zombili izamukeli zesiteshi ezingu-9 no-11 zingasetshenziswa ukusetha izikhulumi ezingu-9 noma ezingu-11 (kuhlanganise ne-one noma ezimbili subwoofers ) ekamelweni lakho lokudlala yasendlini. Lokhu kukuvumela ukuba usebenzise ngokunenzuzo izinhlelo zokucubungula umsindo, njenge-DTS Neo: X.
Kodwa-ke, umamukeli wesiteshi se-9 noma 11 anganikeza nokuguquguquka ngokwemigomo yokwabela iziteshi ezimbili ku-Bi-Amp izikhulumi zangaphambili noma ukusebenzisa iziteshi ezimbili noma ezine ukudala izinhlelo ezimbili zesiteshi se-2 kanye / noma ezintathu ezingasetshenziswa amandla futhi elawulwa yi-receiver oyinhloko. Lokhu kungakushiya nge-5.1 noma 7.1 iziteshi ozisebenzisayo ekamelweni lakho elikhulu lasekhaya.
Futhi, kusukela ngo-2014, ukwethulwa kweDolby Atmos kwendlu yaseshashalazini kubeka enye indlela yokukhethwa kwesiteshi / isikhulumi kokwamukela izakhiwo zasekhaya. Le fomethi evumayo ihlanganisa iziteshi ezizenzekelayo ezinikezele, okuholela ekukhethweni kwamakhethi amasha amasha okufaka okulandelayo: 5.1.2, 5.1.4, 7.1.2, 7.1.4, 9.1.4, nokuningi. Inombolo yokuqala yinombolo yeziteshi ezizungezile, inombolo yesibili yi-subwoofer, futhi inamba yesithathu ibhekisela kunani leziteshi eziqondile.
Olunye uhlobo oluzwakalayo oluzungezile olutholakalayo kwezinye izimpendulo zokudlala ekhaya eziphezulu, ezidinga iziteshi ezingu-9.1 noma ngaphezulu yi- Auro 3D Audio . Okungenani, le fomethi ehambisanayo idinga izendlalelo ezimbili zezikhulumi. Isendlalelo sokuqala kungaba isakhiwo sesiteshi sendabuko 5.1, kodwa-ke esinye isendlalelo, esivela ngaphezu kwesendlalelo sokuqala, sidinga izikhulumi ezimbili zangaphambili nezibili zangemuva. Khona-ke, ukuyiqeda, uma kunokwenzeka, isikhulumi esisodwa esingeziwe esiqongweni sendawo esibekwe ngaphezu kwesihlalo sokuhlala esiyinhloko (okubizwa ngokuthi yi-Voice of God (VOG) isiteshi. Ukuletha inani leziteshi kuze kufike ku-10.1.
Futhi, ukwenza izinto zibe nzima nakakhulu (nakuba zinikeza umsebenzisi izinketho eziningi), isingeniso ngo-2015 we-DTS: X ifomathi yomsindo ozungezile (okungenakudideka ne-DTS Neo: X), engenzi sidinga isakhiwo sesikhulumi esithile, kodwa sinikeza kokubili izingxenye ezizungezile eziqondile futhi eziqondile (isebenza kahle ngaphakathi kwamasethingi asezingeni elifanayo asetshenziswa yiDolby Atmos).
Ukusebenza Okusebenzayo
Khumbula ukuthi iningi le-DVD, i-Blu-ray, nanoma yiliphi umsindo ozwakalayo ozungezile ozothola kusuka kokuqukethwe komthombo lixubene ngokudlala okuyisiteshi esingu-5.1, ngenani elincane lomthombo oxubene nokudlala ukudlala 6.1 noma 7.1. Lokhu kusho ukuthi umamukeli wesiteshi esingu-5.1 noma we-7.1 ne-Dolby / DTS ukukhipha nokucubungula nokucubungula kungagcwalisa kalula umthethosivivinywa (Umamukeli wesiteshi esingu-5.1 angabeka umthombo wesiteshi 6.1 noma 7.1 ngaphakathi kwendawo yesiteshi 5.1).
Uma usuhambela ku-receiver 9.1 noma 11.1 wesiteshi, ngaphandle kokuthi i-Dolby Atmos noma i-DTS: I-X-inikwe amandla futhi isethaphu sokwethulwa ngeziteshi zomgwaqo ezingezansi futhi ezibukeke futhi udlala i-Dolby Atmos / DTS: X okuqukethwe okukhokhelwe, umamukeli empeleni u-post- ukucubungula ama-soundtrack okuyi-original, 5.1, noma i-7.1 ekhompyutheni futhi ukuwabeka endaweni yemikhakha engu-9 noma engu-11 Imiphumela ingaba yinkimbinkimbi, kuye ngokuthi ikhwalithi yemithombo yomthombo, kodwa akusho ukuthi kuyadingeka ukuthi wenze lokhu kuqaqa. Phela, abaningi abanalo ikamelo lazo zonke izikhulumi ezengeziwe!
Okubalulekile
Ukuyibeka yonke into ebonakalayo, isamukeli esihle esiteshini esingu-5.1 siyindlela ehle kakhulu, ikakhulukazi ekamelweni elincanyana noma elingaphakathi kwamahhala amaningi namakhaya.
Kodwa-ke, uma ungena ku-range ye-$ 500 futhi phezulu, kukhona ukugcizelela okwandayo ngabakhiqizi abanezimpendulo ezihlongozwayo zesiteshi esingu-7.1. Ukwengeza, uma ungena ku-$ 1,300 uhla lwamanani entengo uqala ukubona abamukelayo abangu-9.1 wesiteshi. Laba abamukeli banganikeza izinketho zokusetha ngokuguquguqukayo njengoba ukwandisa izidingo zesistimu yakho, noma ube negumbi elikhulu lokudlala ekhaya. Ungakhathazeki ngezintambo, ngendlela-ungahlala uzifihla noma uzifihla .
Ngakolunye uhlangothi, noma ngabe akudingeki ukuthi usebenzise ukugcwele kwesiteshi se-7.1 (noma 9.1) esigabeni sakho sokusetha yaseshashalazini, lezi zamukeli zingasetshenziswa kalula ohlelweni lwesiteshi 5.1. Lokhu kukhulula iziteshi ezimbili noma ezine ezisele kwabanye abamukeli bokusetshenziswa kwe-Bi-amping, noma ukuqhuba amasistimu amabili wesiteshi se-Stereo 2nd Zone.
