Umehluko phakathi kwe-XLR Audio ne-XLR DMX

Ngolunye usuku, ngamunye wethu uqala ukufuna izintambo ezifanele ezinqanyulwe ngepulaki ye-XLR edumile. Lapho siphequlula imikhiqizo yemikhiqizo ehlukahlukene, singabona izinhlelo zokusebenza ezimbili eziyinhloko: Umsindo ne-DMX. Kubonakala sengathi izintambo - izintambo ziyefana, azihlukile komunye nomunye. Ubukhulu obufanayo, amapulaki afanayo, inani elihlukile kuphela, ngakho-ke kufanelekile ukukhokha ngokweqile? Ngokuqinisekile abantu abaningi kuze kube namuhla bazibuza lo mbuzo. Njengoba kuvela - ngaphandle kokubonakala kwamawele ngokusobala, kukhona ukuhluka okuningi.

Ukusetshenziswa

Okokuqala, kufanelekile ukuqala ngezicelo zayo eziyisisekelo. Sisebenzisa izintambo zomsindo ze-XLR ekuxhumeni endleleni yomsindo, ukuxhumana okuyinhloko kwemakrofoni / imakrofoni ne-mixer, amanye amadivaysi akhiqiza isignali, ukuthumela isignali kusuka ku-mixer kuya kuma-amplifiers amandla, njll.

Izintambo ze-XLR DMX zisetshenziswa kakhulu ukulawula izibani ezihlakaniphile. Kusukela kusilawuli sethu sokukhanyisa, ngamakhebuli e-dmx, sithumela kwamanye amadivayisi ulwazi olumayelana namandla okukhanya, ukushintsha kombala, ukubonisa iphethini enikeziwe, njll. Futhi singahlanganisa okokusebenza kwethu kokukhanyisa ukuze yonke imithelela isebenze njengomphumela oyinhloko, “wemodeli”. isebenza.

Isakhiwo

Zombili izinhlobo zine-insulation ewugqinsi, izintambo ezimbili kanye nesivikelo. I-insulation, njengoba kwaziwa, isetshenziselwa ukuvikela umqhubi ezintweni zangaphandle. Amakhebuli ayaphuma aphinde asongwe, agcinwe ezindaweni eziqinile, avame ukunyathela futhi agotshwe. Isisekelo siwukumelana okuhle nezici ezibalwe ngenhla kanye nokuvumelana nezimo. Ukuvikela kwenzelwa ukuvikela isignali ekuphazamiseni kazibuthe kagesi emvelweni. Okuvame kakhulu ngesimo se-aluminium foil, ithusi noma i-aluminium braid.

Umehluko omkhulu

Izintambo zemakrofoni zenzelwe amasiginali omsindo, lapho imvamisa edlulisiwe ikububanzi obungu-20-20000Hz. Imvamisa yokusebenza yezinhlelo ze-DMX ngu-250000Hz, okungaphezulu, "okuphezulu" kakhulu.

Enye into i-wave impedance yekhebula elinikeziwe. Ezintamboni ze-DMX ingu-110 Ω, kumakhebuli alalelwayo ngokuvamile ingaphansi kuka-100 Ω. Umehluko kuma-impedance uholela ekufanisweni kwegagasi okubi futhi, ngenxa yalokho, ukulahlekelwa kolwazi oludluliswa phakathi kwabamukeli.

Ingabe ingasetshenziswa ngokushintshana?

Ngenxa yomehluko wamanani, akekho ozosebenzisa izintambo ze-DMX ngombhobho, kodwa ngenye indlela, ungathola lolu hlobo lokonga ngokuvamile, okungukuthi usebenzisa izintambo zomsindo ohlelweni lwe-DMX.

Ukuzijwayeza kubonisa ukuthi zingasetshenziswa ngokushintshana kungakhathaliseki ukuthi zihloselwe ukusetshenziswa futhi azikho izinkinga ngenxa yalesi sizathu, nokho-ke, isimiso esinjalo singamukelwa kuphela ngaphansi kwezimo ezithile, njengesibonelo, amasistimu okukhanyisa afakelwe amathuluzi angebanzi kakhulu kanye nokuxhumeka okufushane. amabanga (kufika kumamitha amaningana).

Isifinyezo

Isizathu esiyinhloko sezinkinga kanye nokungasebenzi kahle kwezinhlelo okuxoxwe ngazo ngenhla yizintambo ezisezingeni eliphansi kanye noxhumo olulimele, yingakho kubaluleke kakhulu ukusebenzisa izintambo kuphela zohlelo oluthile futhi lufakwe izixhumi zekhwalithi enhle.

Uma sinesistimu yokukhanyisa ebanzi ehlanganisa amadivaysi amaningi, ishumi nambili noma amamitha angamakhulu amaningana wezintambo, kufanelekile ukungeza kuzintambo ezizinikele ze-DMX. Lokhu kuzogcina isistimu isebenza kahle futhi kusisindise ezikhathini ezingadingekile, zokwethuka.
