I-JBL Professional One Series 104 - amamonitha asebenzayo ahlangene

U-JBL ubelokhu enegama elihle emphakathini okhiqiza isitudiyo, okumfanele njengomunye wabakhiqizi abasafufusa. Ngabe uhlelo lwakhe lwakamuva oluhlangene luziveza kanjani kulo mongo?

Amamonitha e-JBL 104 aseqenjini lomkhiqizo elifanayo ne-Genelec 8010, i-IK Multimedia iLoud Micro Monitor, i-Eve SC203 namanye amaningi ano-3-4,5" woofer. Lawa amakhithi eziteshi zokuhlanganisa, amasistimu we-multimedia, aklanyelwe ukusebenza lapho izipikha zekhompyutha ezijwayelekile zinikeza ikhwalithi ephansi kakhulu, futhi ayikho indawo yamamonitha amakhulu asebenzayo.

Amamonitha athunyelwa ngamabhangqa aqukethe okusebenzayo (kwesokunxele) kanye nesethi yokwenziwa exhunywe kusethi yokuqala ngentambo yesipika. Kuzo zombili izimo, i-inverter yesigaba ilethwa kuphaneli elingemuva.

Amakhithi angu-104 ahlinzekwa ngamabhangqa ahlanganisa ikhithi eyinhloko esebenzayo kanye nekhithi yesigqila engenzi lutho. Okokuqala kuhlanganisa: imishini, ama-manipulators kanye nokuxhumana. Eyesibili inomguquli kuphela futhi ixhunywe kusethi eyinhloko ngekhebula le-acoustic. Amamonitha angaxhunywa kumapulagi e-TRS 6,3 mm abhalansile noma amapulaki e-RCA angabhalansi. Izixhumi ezijwayelekile ezilayishwe entwasahlobo zisetshenziselwa ukuxhuma amamonitha. I-monitor esebenzayo inikwe amandla ngokuqondile kuma-mains, ine-switch ye-voltage, isilawuli sevolumu esikhulu, okokufaka kwe-stereo Aux (3,5 mm TRS) kanye nokuphuma kwe-headphone yokuvala ama-monitor.

Izindlu zokuqapha zenziwe ngepulasitiki ye-ABS futhi zinesembozo sensimbi ngaphambili. Ngezansi kunephedi ye-neoprene egcina amakhithi ephephile phansi. Umkhiqizi uthi umumo nomklamo wamamonitha kuguqulelwa ukusetshenziswa kwedeskithophu.

Isici esithakazelisayo se-104 ukusetshenziswa kwabashayeli be-coaxial abane-3,75 "woofer. Umshayeli omiswe kahle une-diaphragm eyi-diaphragm ye-diameter ye-diameter futhi ifakwe i-waveguide emfushane. Lona umklamo wangempela onesicaba ngendlela ehlukile, uma kubhekwa usayizi wawo, impendulo yemvamisa.

Ikesi, lapho ingekho indiza eyisicaba, iyisixazululo se-bass-reflex esinomhubhe olahlekile ogobe ngendlela emangalisayo. Ekupheleni kwayo kwangaphakathi, i-elementi yokudambisa ifakiwe ukunciphisa ukuxokozela futhi yethule ukumelana ne-acoustic ukuze kwandiswe i-resonance ye-inverter yesigaba.

Ukuhlukaniswa phakathi kwe-woofer kanye ne-tweeter kwenziwa kancane kancane nge-unipolar capacitor efakwe kumbhobho. Lesi sixazululo sikhethwe ukuze singaxhumi abaqaphi ngezintambo ezimbili, okubonakala sengathi ukunyakaza okunengqondo. Izipikha zinikwa amandla imojula yedijithali ye-STA350BW ephakela abashayeli abangu-2×30W.

Ekuzijwayeza

Umhubhe we-inverter wesigaba obonwa kwesokunxele unomumo wophawu lombuzo. I-Damping ngokokufaka kwayo kuklanyelwe ukunciphisa ukuxokozela nokulinganisa ukuzwakala. Umsebenzi we-passive crossover wenziwa i-capacitor enamathiselwe phezulu kwesiguquli.

Phakathi nezivivinyo, i-JBL 104 yagijimela kukhithi ye-Genelec 8010A esele isunguliwe emakethe - i-multimedia, kodwa enokunambitheka okucacile kochwepheshe. Ngokwezintengo, ukuqhathanisa kufana nomshayisibhakela we-featherweight vs. Kodwa-ke, ebesikufuna ngokuyinhloko umlingiswa we-sonic kanye nakho konke okulalelayo kokubalulekile okuyinkimbinkimbi namathrekhi awodwa avela ezinhlotsheni ezahlukahlukene zemikhiqizo enamathrekhi amaningi.

Ukukhiqizwa kabusha komsindo we-wideband ye-104 kubonakala kukhulu kakhulu futhi kujulile kunokuba ubukhulu balesi simiso busikisela. Ibhesi isethwe ngaphansi kuka-8010A futhi ibonwa kangcono. Umsindo, nokho, ungowomthengi, onokuvela kancane kokugcina isikhathi kwe-mids ne-bass. Amafrikhwensi aphezulu acacile futhi afundeka kahle, kodwa acacile kakhulu kunama-Genelec monitors, nakuba azwakala emangalisa kakhulu. Idizayini ye-coaxial ye-transducer isebenza kahle emkhakheni wamahhala lapho zingekho izindawo ezikhanyayo eduze kwemonitha, kodwa kudeskithophu, ukuvumelana kokuqondisa akubonakali ngendlela esobala. Ngokungangabazeki, i-JBL 104 isebenza kahle kakhulu uma ibekwe ngemuva kwedeskithophu kuma-tripods ukuze kuncishiswe umphumela wokuboniswa kwedeskithophu.

Futhi, ungalindeli amazinga aphezulu okucindezela. Ngenxa yomklamo wayo othize, i-transducer ibonakala ngokucindezelwa kwamandla amaningi, ngakho-ke ukudlala ngokuzwakalayo ngezinga eliphezulu le-bass akuwona umqondo omuhle. Ngaphezu kwalokho, zombili iziguquli zinikwa amandla yi-amplifier evamile - ngakho-ke ngevolumu ephezulu uzozwa ukuncishiswa komkhawulokudonsa. Nokho, lapho izinga le-SPL lingeqi u-85 dB ojwayelekile phakathi neseshini yokulalela, azikho izinkinga ezizovela.

Abashayeli abasetshenzisiwe bangokwakhiwa kwe-coaxial nge-tweeter ngaphakathi kwe-woofer.

Isifinyezo

Idizayini ethakazelisayo nomsindo ohlaba umxhwele kwenza i-JBL 104 ithakazelise kubantu abafuna amamonitha omsebenzi womsindo oyisisekelo noma ukulalela umculo okuvamile.
