Ukusetha i-subwoofer emotweni
Okuqukethwe
I-subwoofer iyisengezo esihle kusistimu yomsindo wemoto. Kodwa kufanelekile ukucabangela ukuthi ukuthenga i-subwoofer ebizayo akuqinisekisi umsindo wekhwalithi ephezulu, ngoba le divayisi idinga ukushunwa kahle. Ukuze uxhume futhi usethe i-subwoofer kahle, akumele ube nokuzwa okuhle kuphela, kodwa futhi nolwazi olujulile lwethiyori yomsindo wemoto.
Yiqiniso, ngaphambi kokusetha i-subwoofer emotweni, kungcono ukufuna usizo kochwepheshe, futhi kulabo abashayeli abafuna ukuzenza ngokwabo, lesi sihloko sizoba usizo.
Ungaqala kuphi ukusetha i-subwoofer?
Ukulungiswa kwe-subwoofer kuqala kusukela ngesikhathi ibhokisi lenziwa. Ngokushintsha izici zebhokisi (ivolumu, ubude bechweba), ungafinyelela imisindo ehlukene. Kulokhu, udinga ukwazi kusengaphambili ukuthi yimaphi amafayela alalelwayo azodlalwa kakhulu emotweni, kanye nokuthi iyiphi i-amplifier ezoxhunywa ohlelweni lomsindo. Lapho i-subwoofer isivele inikeziwe esimweni somkhiqizi, khona-ke ukuguquguquka kokusetha kunqunyelwe, nakuba ngolwazi oludingekayo kungenzeka ukufeza ikhwalithi yomsindo oyifunayo.
Esinye sezici ezibalulekile ezithinta ikhwalithi yomsindo yi-amplifier, sikweluleka ukuthi ufunde isihloko esithi "Indlela yokukhetha i-amplifier".
Ukulungiselelwa kwesihlungi se-LPF (lowpassfilter).
Okokuqala udinga ukusetha isihlungi se-low-pass (LPF). Yonke i-subwoofer namuhla inesihlungi se-LPF esakhelwe ngaphakathi. Isihlungi sikuvumela ukuthi ukhethe umkhawulo lapho siqala khona ukuvimba amaza aphezulu, okuvumela isignali ye-subwoofer ukuthi ihlangane ngokwemvelo nezinye izipikha.
Ukufaka isihlungi, njengokusetha i-subwoofer esebenzayo, kuhlanganisa ukuhlola okuningi - ayikho “ifomula” eqondile eqondile.
I-subwoofer yakhelwe ukukhiqiza kabusha amaza aphansi, ayikwazi ukucula, lokhu kungumsebenzi wezikhulumi. Ngenxa yesihlungi se-LPF ephansi, singenza i-subwoofer idlale ibhesi yesimanje. Udinga ukwenza isiqiniseko sokuthi inani lokuhlunga alisethiwe phezulu kakhulu nokuthi i-subwoofer ayidluleli ama-woofers wezipikha zakho zobubanzi obugcwele. Lokhu kungaholela ekugcizeleleni ngokweqile kububanzi obubodwa befrikhwensi (yisho, cishe ku-120 Hz) kanye nesistimu yesipikha esingaqondakali. Ngakolunye uhlangothi, uma usetha isihlungi siphansi kakhulu, kungase kube nomehluko omkhulu kakhulu phakathi kwesignali ye-subwoofer kanye nesignali yesipika.
Ububanzi be-subwoofer ngokuvamile bungu-60 kuye ku-120. Zama ukusetha isihlungi se-LPF kokuthi 80 Hz kuqala, bese uhlola umsindo. Uma ungakuthandi, lungisa iswishi kuze kube yilapho izipikha zikhala ngendlela ofuna ngayo.
Emsakazweni ngokwawo, isihlungi kufanele sicishwe.
Ukushuna kwe-subsonic
Okulandelayo, udinga ukwenza kusebenze isihlungi se-infrasonic, esibizwa ngokuthi "subsonic". I-subsonic ivimba amaza aphansi kakhulu avela ngokwemvelo kwezinye izingoma. Awukwazi ukuzwa la maza ngoba akhona ngaphansi komkhawulo wokuzwa komuntu.
Kodwa uma zingasikiwe, i-subwoofer izosebenzisa amandla engeziwe ukuze zizidlale. Ngokuvimbela amaza e-infra-low, idivayisi izokwazi ukukhiqiza kabusha ngokunembile lawo mafrikhwensi angaphakathi kwebanga elizwakalayo. Ngaphezu kwalokho, kulokhu, ukwehluleka kwekhoyili ye-subwoofer ngenxa yokunyakaza okusheshisa kwe-diffuser akufakiwe.
Iyini i-Bassboost?
Ama-amplifiers amaningi afaka ne-switch ye-Bassboost engakhuphula amandla e-subwoofer ngokuyibekela imvamisa ethile. Abanye abashayeli bezimoto basebenzisa iswishi ukwenza umsindo "ucebe", nakuba ngokuvamile isetshenziselwa ukusabalalisa ama-bass ngokulinganayo. Uma usetha ukushintshwa kwenani eliphakeme, khona-ke i-subwoofer ingashisa, noma kunjalo, ukuvala i-Bassboost ngokuphelele futhi akufanele, ngoba kulokhu, i-bass ingase ingazwakali nhlobo.
Ukulungisa Ukuzwela Kokufaka (GAIN)
Abanye abashayeli abayiqondi indlela yokusetha kahle ukuzwela okokufaka. Ukuzwela kokokufaka kubonisa ukuthi ingakanani isignali engasetshenziswa kokokufaka ukuze kutholwe amandla okukhiphayo alinganiselwe. Kufanele ilungiswe ukuze kujwayeleke i-voltage yesiginali yokufaka.
Kubaluleke kakhulu ukusetha ukuzwela okokufaka ngendlela efanele, njengoba lokhu kuzosiza ukugwema ukuhlanekezela kwesignali, ikhwalithi yomsindo ephansi, noma ukulimala kwezipikha.
Ukuze ulungise i-"GAIN", udinga
- i-voltmeter yedijithali engakala amanani kagesi we-AC;
- i-CD yokuhlola noma ifayela eliqukethe i-0 dB sine wave (kubaluleke kakhulu ukuthi ungasebenzisi isignali yokuhlola encishisiwe);
- imiyalo ye-subwoofer, ekhombisa amandla okukhipha amandla avumelekile.
Okokuqala udinga ukunqamula izintambo zesipika ku-subwoofer. Okulandelayo, udinga ukuqinisekisa ukuthi ama-bass, ama-equalizers namanye amapharamitha avaliwe kuyunithi yekhanda ukuze uthole umsindo ocacile. Kulesi simo, izinga lokuzwela okokufaka kufanele libe phansi ngangokunokwenzeka.
Qiniseka ukuthi i-voltmeter yedijithali ingafunda i-voltage ye-AC futhi iyixhume kumatheminali esipikha kuzipikha zakho (ungayivikela nge-screwdriver). Ngemuva kwalokho, kuzodingeka uguqule ukuzwela "ukusonta" kuze kube yilapho i-voltmeter ikhombisa inani le-voltage elidingekayo, elikhonjiswe encazelweni.
Okulandelayo, ifayela lomsindo elirekhodiwe eline-sinusoid kufanele linikezwe i-subwoofer ngezikhathi ezithile ngokushintsha ivolumu yesistimu yomsindo kuze kube yilapho kwenzeka ukuphazamiseka. Uma kwenzeka ukuphazamiseka, ivolumu kufanele ibuyiselwe kunani layo langaphambilini. Okufanayo kuya ekulungiseni ukuzwela. I-oscilloscope ingasetshenziswa ukuthola idatha enembe kakhulu.
Isigaba se-Acoustic
Ama-subwoofers amaningi aneswishi ngemuva ebizwa ngokuthi "Isigaba" engasethelwa ku-0 noma 180 degrees. Ngokombono kagesi, lena into yesibili elula ukuyenza ngemva kokuvula/ukuvala iswishi.
Uma usetha iswishi yamandla ngasohlangothini olulodwa, khona-ke amakhondaktha amabili azophatha isignali isuka kokuphumayo iye kuwo wonke amanye ama-electronics ohlangothini olulodwa. Kwanele ukushintsha iswishi futhi amakhondatha amabili ashintshe indawo. Lokhu kusho ukuthi ukuma komsindo kuzohlehliswa (okuyilokho onjiniyela abakushoyo uma bekhuluma ngokuhlehlisa isigaba, noma ukusishintsha ngo-180 degrees).
Kodwa yini isilaleli esivamile esiyitholayo ngenxa yokuhlelwa kwesigaba?
Iqiniso liwukuthi ngosizo lokukhwabanisa nge-switch yesigaba, ungakwazi ukufeza umbono ophezulu we-bass ephakathi nendawo ephezulu ngenkathi ulalele. Kungenxa yesiguquli sesigaba ukuthi ungakwazi ukuzuza wonke amabhesi owakhokhele.
Ngaphezu kwalokho, ukulungiswa kwesigaba se-monoblock kusiza ukufeza ncamashi umsindo wangaphambili. Ngokuvamile kwenzeka ukuthi umsindo usatshalaliswa ngokungalingani kulo lonke ikhabethe (umculo uzwakala kuphela esiqwini).
Ukubambezeleka
Ama-Subwoofers avame ukuba nokubambezeleka okuncane, futhi alingana ngokuqondile nosayizi webanga. Isibonelo, izikhulumi ezivela kumkhiqizi waseMelika i-Audissey zibeke ngamabomu ibanga elide ukuze kuvinjelwe lokhu kubambezeleka.
Kumele kuqashelwe ukuthi ukulungiswa kwe-amplifier manual ye-subwoofer kungenzeka kuphela uma kukhona iprosesa yangaphandle noma iprosesa edidiyelwe. Isibonakaliso sokuthi i-subwoofer idala ukubambezeleka i-bass ehlala isikhathi eside, ephazamisa umsindo ngezinye izikhathi. Injongo yokusetha ukubambezeleka ukuzuza ukudlala ngesikhathi esisodwa kwe-subwoofer nezipikha zangaphambili (umsindo akufanele uvunyelwe ukudebeza ngisho imizuzwana embalwa).
Kungani kubalulekile ukudokha ama-subwoofers nama-midbass ngendlela efanele?
Uma i-subwoofer ifakwe kahle ne-midbass, khona-ke umsindo uzoba sezingeni eliphansi futhi uphansi. Lokhu kubonakala ikakhulukazi kumafrikhwensi aphansi, lapho kutholakala uhlobo oluthile lombhedo esikhundleni sama-bass ahlanzekile. Ngezinye izikhathi izinketho ezinjalo ezidabukisayo zingenzeka, lapho umsindo ovela ku-subwoofer uzodlala ngokuzimela.
Eqinisweni, lokhu kusebenza kuzo zonke izinhlobo zomculo, hhayi nje, ukusho, umculo we-classic noma we-rock, lapho kudlalwa khona izinsimbi zomculo "bukhoma".
Isibonelo, kumathrekhi ayingxenye ye-EDM, edume kakhulu kubantu abasha, amabhesi agqamile atholakala ngqo lapho kuhlangana khona i-midbass. Uma uwafake kudokhu ngokungalungile, khona-ke amabhesi anomsindo ophansi ngeke ahlabeke umxhwele kangako, futhi okubi kakhulu ngeke azwakale.
Njengoba kudingekile ukushuna i-amplifier kumafrikhwensi afanayo, kuyanconywa ukuthi usebenzise isihlaziyi se-audio spectrum ukuze uthole idatha enembe kakhulu.
Ukuqonda kanjani ukuthi usethe i-subwoofer ngendlela efanele?
Uma i-subwoofer ixhunywe ngendlela efanele, khona-ke abantu abasemotweni abakwazi ukuyizwa, ngoba akufanele iphazamise isignali eyinhloko.
Uma ulalela umculo ngevolumu ephansi, kungase kubonakale sengathi awekho ama-bass anele. Ukuntuleka kwe-bass ngamavolumu aphansi kuwuphawu oluqinisekile lokuthi i-subwoofer ixhunywe ngendlela efanele.
Yebo, akufanele kube khona umsindo, ukuhlanekezela noma ukubambezeleka kusiginali yomsindo, futhi akunandaba ukuthi hlobo luni lomklamo olusetshenziswayo.
Amaphesenti e-bass kuthrekhi ngayinye kufanele ahluke, okungukuthi, ukudlalwa kabusha kufanele kufane ngokuphelele nengoma yokuqala eqoshwe umdidiyeli.
Isihloko esilandelayo sincoma ukuthi sifundwe sinesihloko esithi "Indlela Ibhokisi le-Subwoofer Liwuthinta Ngayo Umsindo".
