2.1 Isiteshi seKhaya leSeshayamathala seSikhathi Somsakazo 5.1 Isisindo Somsindo
2.1 Isiteshi Somsakazo Wasekhaya WaseSeshashalali Isichazamazwi
Ngokungafani nezikhulumi ezijwayelekile ze-stereo, uhlelo lwe-2.1 Channel Home Theater uhlelo lwe-stereo olwenzelwe ukuletha umsindo wendawo yaseshashalazini. Uma kuqhathaniswa nesistimu evamile yomsindo wesiteshi esivamile 5.1, isistimu yesiteshi 2.1 ihlanganisa izikhulumi ezimbili kuphela ze-stereo kanye ne-subwoofer eyodwa ukudlala umsindo kusuka emithonjeni exhunyiwe. Enye inzuzo ephawulekayo yokusebenzisa amasistimu emidlalo yaseshashalazini angu-2.1 wesiteshi ukuthi bayakujabulela ukujabulela ama-movie nomculo ngaphandle kwesidingo sezungezwe ezizungezile kanye / noma isikhungo; ungase futhi ujabulele i-clutter encane kakhulu ekusebenzeni izintambo ezengeziwe . Ngaphezu kwakho konke, amasistimu e-2.1 wesiteshi abuye abe isinyathelo esikhulu esivela kumsindo oyisisekelo okhishwe izikhulumi ezincane ezakhiwe kumathelevishini amaningi.
5.1 Isiteshi se-Sound Defined
Imikhosi eminingi ye-TV ne-DVD / Blu-ray movie zikhiqizwa umsindo ozungezile, okuhloswe ukuba ujabulele ohlelweni lomsindo wesiteshi 5.1. Isikhulumi ngasinye kwisistimu yesiteshi 5.1 sinendima ebalulekile okufanele idlale kulo lonke umsindo. Kodwa-ke, yizikhulumi zangaphambili (noma ze-stereo), ezifana nesistimu yesiteshi se-2.1, ezibaluleke kakhulu . Ngokuvamile, izikhulumi zangaphambili ziveza okuningi kwesenzo esikrinini esikrinini. Kungaba imoto yokushayela noma umsindo wabantu abakhuluma nezibuko ukuchofoza endaweni yeseva noma yokudlela. Iningi kunoma yimaphi imisindo esiza ababukeli bexhuma esiteshini bazwakala ngezikhulumi zangaphambili.
Esikhathini sesistimu yesiteshi 5.1, isikhulumi sesikhungo sinikezwe umsebenzi wokukhiqiza ikhwalithi yenkulumo , okungukuthi (kusobala) ingxenye ebalulekile kunoma iyiphi indaba. Kodwa esimisweni sesiteshi se-2.1, ingxoxo ihanjiswa ezikhulwini zangakwesobunxele nangakwesokudla ukuze izwe futhi ingalahlekile. Khona-ke unayo izikhulumi ezizungezile eziseduze ohlelweni lwesiteshi 5.1, oluveza imisindo engekho esikrinini. Lezi zindlela zakha insimu yomsindo ozwakalayo lapho imisindo nemiphumela ekhethekile zizwakala kuzo zonke izinkomba. Uma isetshenziswe kahle nangempumelelo, izikhulumi ezizungezile zengeza ubuqiniso nokujabula kumabhayisikobho nomculo. Esikhathini sesistimu yesiteshi se-2.1, umsindo ovela ezikhulumeni ezizungezile uphinde ulandelwe izikhulumi zangaphambili. Ngakho-ke usuzwa umsindo wonke, nakuba uvela kuphela futhi ungasuki ngemuva kwegumbi. Isiteshi se-subwoofer - esaziwa njenge-.1 (iphuzu elilodwa) isiteshi ngoba senza kuphela izisekelo ezingcono - zithuthukisa umthelela, ubuqiniso, nokukhiqizwa komsindo we-TV, ama-movie nomculo.
I-TV, ama-Movie, noMculo
Ngokusho nje, isistimu yesiteshi se-2.1 iveza iTV, umsindo we-movie, nomculo enezikhulumi ezimbalwa, i-wiring encane, kodwa injabulo cishe. Abantu abaningi bakhetha ukulula komsindo wesiteshi esingu-2.1 futhi bathola ukuthi bangasebenzisa uhlelo lwabo lwe-stereo olukhona kunokuba bathenge uhlelo olusha lomdlalo wendawo yaseshashalazini . Abanye baneliseke ngokuphelele ngomsindo. Kodwa-ke, kunezinye izilaleli ezingeke zilungele lutho olungaphansi kwesistimu yomsindo ozungezayo wesiteshi esiningi . Isizathu esisodwa esiyinhloko ukuthi kungani umsindo wesiteshi esingu-5.1 udala umuzwa wokuthuthukiswa, lapho umculo nomphumela wengezela khona ubuqiniso, ukusola, nokugubha njengokungathi ulungile phakathi kwendawo . Kodwa into esemqoka okumele uyikhumbule ukuthi i-movie kufanele ibe nakho konke okuqalayo (okufaka ikhodi kufomethi yezindaba). Uma ujabulela okuqukethwe okungenayo yonke leyo mibala ehlanganisiwe yemiphumela yokubukwa komsindo, uhlelo lwesiteshi 2.1 lunganikeza isipiliyoni esifanayo kakhulu kodwa ngenani elikhulu kakhulu.
Ingabe i-2.1 Channel System Right For You
Ngomculi othakazelayo, uhlelo lwesiteshi 5.1 luyadingeka. Kodwa ngomlaleli ongavamile, uhlelo lwe-2.1 wesiteshi lungahle lukhethwe ngokulula kwalo, izindleko eziphansi, nokulula ukusetshenziswa. Uhlelo lwesiteshi 2.1 lungcono emakamelweni amancane, ezindlini zokulala, izibungu, noma ezindaweni lapho isikhala sinqunyelwe khona. Izinhlelo ezinjalo zesiteshi 2.1 nazo zinhle kulabo abangenayo indawo yezikhulumi ezizungezile futhi / noma abafuni ukuhlukunyezwa nezintambo. Ngenkathi uhlelo lwesakhiwo semidlalo yaseshashalazini luzohlinzeka ngokuhlangenwe nakho okulalele kakhulu, uhlelo lwesiteshi 2.1 luzovumela ukuthokozela kalula komculo nama-movie - ngezwi elingokoqobo - kodwa ngaphandle kokuhlanganiswa kwezipikha nezintambo ezengeziwe.
Indlela Yokuzungezelana Ngomsindo Ngaphandle Kokukhulumisana Kweziteshi Zamuva
Amanye amasistimu wesiteshi angu-2.1 anamakhemikhali akhethekile okudala ukukhohlisa kwemiphumela yomsindo ezungezile ngezikhulumi ezimbili, eyaziwa ngokuthi i-Virtual Surround Sound (VSS). Nakuba kukhonjiswe ngamagama ahlukene (abakhiqizi bavame ukudala amagama ngobuchwepheshe babo obufanayo kodwa obunikazi), izinhlelo ze-VSS zinomgomo ofanayo - ukwakha umphumela ozwakalayo womsindo ngokusebenzisa izikhulumi ezimbili eziphambili kanye ne-subwoofer. Izindlela ezehlukene zesiteshi 2.1 zisebenzisa ama-decoder wesiteshi 5.1 ezihlangene nezifunda ezikhethekile zedijithali ezifanisa umsindo wezikhulumi zesiteshi zangemuva. I-VSS ingaqiniseka kakhulu ukuthi ungaphenduka ikhanda uma uzwa 'umsindo ozwakalayo' ovela ngemuva kwakho.
Izinhlelo zesiteshi sekhaya sase-2.1 zesiteshi
Amasistimu e-pre-packed noma e-in-one njengeBose, Onyko, noma i-Samsung (ukubiza abambalwa) afaka konke okudingayo ngaphandle kwethelevishini. Lezi zinhlelo zine-receiver eyakhelwe ngaphakathi, isidlali se-DVD , izikhulumi ezimbili, ne-subwoofer yezwi langempela lendawo yaseshashalazini endaweni eqondile, elula ukuyisebenzisa.
