Izintambo ezilinganayo nezingalingani - umehluko

Amakhebuli aphakathi kwezinto eziyisisekelo zemishini yesitudiyo ngasinye. Kungakhathalekile ukuthi kuzoba isitudiyo esikhulu sochwepheshe noma esincane, ngokuvamile isitudiyo sasekhaya, sisebenza ngezintambo kuzo zonke. Ngakho-ke, ukukhetha ikhebula elifanele ukuxhuma imishini yethu kubaluleke kakhulu futhi kuthinta ikhwalithi yomsindo otholiwe. Ngaphambi kokuba senze isinqumo sokuthenga, kufanele siqale sijwayelane nezinhlobo zabo, izinzuzo kanye nokubi, ngoba kokubili okulinganayo kanye ne-asymmetrical banayo.

Izintambo ezingalingani zihlanganisa, phakathi kwabanye labo abaneziphetho ezimbili ze-RCA, okuthiwa ama-cinches ezinhlangothini zombili noma lapho sinama-cinches amabili ngakolunye uhlangothi kanye ne-jack ngakolunye, noma lapho sine-jack ezinhlangothini zombili. Lezi zintambo zihlukaniswa yiqiniso lokuthi zinama-conductor amabili emugqeni owodwa, omunye wabo ophethe isignali yomsindo nomunye ophansi. Lezi zintambo zigijima ubude obugcwele bekhebula ukusuka kokungenayo kuye kokuphumayo. Ububi balesi sixazululo ukuthi lapho ikhebula lihlangabezana nokuphazamiseka okuthile ngendlela yamagagasi endleleni yayo, lezi ziphazamiso zizophuma ekugcineni futhi zizozwakala. Ngakho-ke, lezi zinhlobo zezintambo akufanele zisetshenziselwe ukuxhumana okude njengoba zizoqoqa umsindo omkhulu endleleni yazo kangangokuthi ungawuzwa ngezipikha zakho. Vele, ilungele ukuxhumana okufushane kanye nokusetshenziswa kwasekhaya okujwayelekile njengalapho kuxhunywa umbhoshongo, ngoba kulolu hlobo lwamadivayisi akukho ukuxhumana okungcono kunokungalingani, ngakho-ke ikhebula le-symmetrical ngeke lisetshenziswe ngokugcwele noma kunjalo. Ezindaweni ezishibhile zomsindo noma izikhulisa-zwi ezishibhile akukho ukuxhumana okulinganayo, ngakho-ke ikhebula elinjalo elingalingani lizosetshenziswa lapho. Ububi obuyinhloko balolu hlobo lwekhebula elingalingani ukuthi alusebenzi kahle ekuxhumekeni okude.

Kodwa-ke, ngokuxhumeka okude akukho nkinga ngekhebula le-symmetrical, eliwusizo ikakhulukazi ekuxhumekeni kwe-studio. Le mpi yekhwalithi yomsindo ehamba phambili iyiqiniso lansuku zonke kuwo wonke umqondisi womsindo nomdidiyeli. Ngakho-ke, lolu hlobo lwekhebula lusetshenziswa kabanzi hhayi kuphela ekuxhumaneni okude, njengamakhonsathi avulekile, kodwa futhi nakumafushane adinga umsindo ocacile, wekhwalithi ephezulu. Esitudiyo, ngosizo lwabo, sihlanganisa, phakathi kwamanye ama-microphone we-condenser ane-interface yomsindo noma i-mixer. Lezi zintambo zinomklamo ohluke kancane futhi zisebenza ngendlela ethe ukuhluka. Kukhona izintambo ezintathu lapha, hhayi ezimbili njengoba kwakunjalo ngezingalingani. Isibonelo, kukhebuli ye-XLR kukhebula yemakrofoni evamile, ucingo olulodwa lubophezeleka phansi, futhi ezimbili zinesibopho sesignali yomsindo. Njengasendabeni yekhebula elingalingani, lezi zintambo nazo zindiza kubo bonke ubude bekhebula ziye ekuphumeni, ngomehluko wokuthi amasiginali womsindo amabili ahluke kancane. Lawa amakhophi afanayo esignali, kodwa umqhubi wakamuva unomfanekiso wesignali ongu-180 °, okungukuthi i-polarized, okungukuthi i-mirror reflection. Le ntambo, njengasendabeni yekhebula elingalingani, ingase iphinde ihlangabezane neziphazamiso ezihlukahlukene endleleni, nayo ezoqoqwa ngomehluko kuphela wokuthi ekugcineni lapho isignali ikhishwa, isignali eyaguqulwa ekuqaleni kwenye ye amakhebuli alalelwayo aphinde ahlanekezelwe futhi ahlanganiswe nentambo yesibili yomsindo. Lokhu kusho ukuthi zombili lezi zimpawu zokukhiphayo zisesigabeni esihambisanayo, ze-polarized, zinesimo segagasi esifanayo, esibangela ukuthi ukuphazamiseka okuqoqwe endleleni phakathi nokugeleza kwesignali kukhanselwe. Sinesignali ehlanzekile, engcono kakhulu.

Izintambo ezilinganayo ngokuvamile ziyizintambo ezingcono futhi ngisho nokuxhumeka okufushane kungcono ukuzisebenzisa. Yebo, lokhu kunengqondo kuphela lapho okokusebenza kwethu esikusebenzisayo kusebenzisa uxhumano olunjalo. Kodwa-ke, kufanele zisetshenziselwe ukuxhumana okude, ngoba lapho sizozizwa sisezingeni eliphezulu kakhulu. Endabeni yokusebenzisa ikhebula elingalingani ekuxhumeni kwamamitha ambalwa, singakwazi kakade ukubona ukwehla kwekhwalithi yesignali, futhi ngokuxhumeka kwamamitha amaningana, kubonakala. Ngekhebula elilinganayo, ngisho namabanga anjalo angama-100 m awebi futhi umsindo ophumayo muhle kakhulu. Kodwa-ke, kufanele kuhlale kukhunjulwa ukuthi indlela emfushane yokuhamba kwegagasi lomsindo, ikhwalithi yomsindo ophumayo izoba ngcono. Ngakho-ke, ake sizame ukuthi singagcini ikhebula futhi, lapho siqeda okokusebenza kwethu, sizame ukukhulisa usayizi wayo ngokwesidingo sangempela.
