Abaqaphi be-KRK Rokit 5 G4 Studio

I-KRK Rokit ngokungangabazeki ingelinye lamamonitha aziwa kakhulu emhlabeni, asetshenziswa ezitudiyo zokuqopha ekhaya nangale kwalokho. I-G4 iyisizukulwane sabo sesine. Izinguquko ku-G3 zinkulu kangangokuthi singakhuluma ngomkhiqizo omusha ngokuphelele.

Nakuba iqembu labaqaphi lifakiwe Uchungechunge lwe-G4 sizothola amamodeli amane, ngagcizelela ukuthi ngingathanda ukuhlola okungenaniс 5 "uboya.

Okokuqala, angikholelwa ekukhiqizeni kabusha kwe-bass okufanelekile emakamelweni amancane lapho ibhajethi eseduze neziqaphi zenkundla zivame ukusetshenziswa khona. Ukwandisa ububanzi be-woofer, ngezinye izikhathi okuhlotshaniswa nokwehlisa imvamisa ephansi kakhulu ephathwa umqapha, akwenzi umqondo omkhulu ezimweni ezinjalo, ngaphandle kokunikeza umbono we-bass ephansi. Kodwa-ke, i-bass enjalo ihlala ingalawuleki futhi ngisho nangaphezulu i-psychoacoustic phenomenon kunolwazi oluthembekile lomsindo.

Ibhulokhi ye-DSP ilawulwa isibonisi sekristalu ewuketshezi nesishumeki esinomsebenzi wenkinobho. I-encoder ngokwayo futhi ikuvumela ukuthi ulungise ukuzwela okokufaka kwamamonitha.

Isizathu sesibili sokuthi ngihlale ngikhetha amamonitha angu-5-6 yingoba ayadingeka ekusetheni okukhulu. imvamisa ye-crossover ephansi, okuholela ekwehleni kokusebenza kwezibukeli ngokwesilinganiso.

Lokhu akusho ukuthi amathuba amanye ngaphandle kwamakhithi angu-5 intshi awanqunyelwe. Abaningi bakhetha umsindo wesikhombisa noma isishiyagalombili, futhi angimangali nakancane. Anomsindo, ashukumisayo futhi akhiqiza amabhesi ngokuphumelelayo. Kodwa-ke, uma kufanele ngikhethe, ngivame ukukhetha ama-Fives ngoba azoba abamele kakhulu kulo lonke uchungechunge futhi angasho okuningi mayelana nomqondo ongemuva kwawo. Kubonakala sengathi kuleli cala ngikwazile ukungenzi iphutha ...

Imibuzo yezezimali

Eminyakeni embalwa edlule, lapho ebuzwa ukuthi yiziphi iziqapha kufika ku-PLN 1500 umbhangqwana ngamunye Ngingancoma, impendulo kuphela kwaba ukumamatheka. Manje, ngaphandle kokungabaza, ngithi wonke umuntu. Umehluko phakathi kwezinhlelo ezifana ne-Adam Audio T5V, JBL 306P MkII, Kali Audio LP6 futhi ekugcineni I-KRK Rokit 5 G4 zinhle ngokwendalo. Ukuthenga noma iyiphi yazo ngeke kube yiphutha inqobo nje uma sazi ukuthi imayelana nani eduze nabaqaphi benkambu okuhloselwe umsebenzi wokuklama kanye premixhhayi ukuxuba professional kanye mastering.

Inani: PLN 790 (ngalinye); Umkhiqizi: KRK Systems, www.krksys.com Ukusabalalisa: AudioTech, www.audiotechpro.pl

Ezimweni ezimbili zokugcina, udinga ukuqala nge-PDU (igumbi, isipiliyoni, amakhono), bese abaqaphi obakhethile bazozisula ngokwabo. Futhi ngiyaqinisekisa ukuthi ngeke babe sebangeni elingafika ku-PLN 1500. Kodwa-ke, ezitudiyo zokuqopha zasekhaya nezamaphrojekthi, kanye nohlobo lomsebenzi esivame ukuwenza ezindaweni ezinjalo, lezi ziqapha zizoba zilungile. Kukubo lapho sizokwandisa isici sethu se-PDU somuntu siqu.

Iziguquli

I-Rokit 5 G4 iziqaphi ezinezindlela ezimbili, ezisebenzayo, ezisebenza ngemodi ye-bi-amp futhi zisekelwe kukhabhinethi ye-MDF bass-reflex - ncamashi njengeningi lamasethi alolu hlobo. Pho bahluke kanjani kwabanye? Ama-diaphragm omshayeli we-aramid ophuzi? Yebo, ikhadi lebhizinisi le-KRK, kanye nelogo ekhanyisiwe. I-inverter yesigaba igijima emaphethelweni aphansi wephaneli yangaphambili futhi inemiphetho eyi-contour. Yebo, lokhu kuyinto ejabulisa kakhulu. Okuthakazelisa nakakhulu ukuthi umhubhe we-bass-reflex unomklamo okhethekile - ugobile usesimweni sohlamvu oluyindilinga L futhi mude impela, ugcina cishe uhhafu wobude bemonitha.

Mayelana nokusetshenziswa high frequency converter ezinye izinto ezinhle ongazisho. Lona umshayeli owenziwe kahle onozibuthe omkhulu we-ferrite kanye ne-dome yokwenziwa edambisa ama-resonances kahle. Inezinga eliphansi kakhulu lokuhlanekezela kanye nokuqondisa okuhle kakhulu, okuthi ekamelweni elihle ngokuzwakalayo kuqinisekisa ukuma okulula kwemithombo kanye nokuzinza kwayo ku-panorama.

Izihlungi ezitholakala esigabeni se-EQ zisebenza njengokusetha ngaphambilini: ezine zamafrikhwensi aphansi nezine zamafrikhwensi aphezulu. Kuzo zombili izimo, isilungiselelo sesithathu sikhubaza ukuhlunga. Kumafrikhwensi aphansi, isilinganisi sihlanganisa isihlungi seshelufu esingu-60 Hz nesihlungi sokudlula sebhendi engu-200 Hz, kanye namaza okuphakama aphezulu, isihlungi seshelufu esingu-10 kHz nesihlungi sokudlula sebhendi esingu-3,5 kHz.

Kuzwakala kukuhle - kusobala, akukho msindo, kukhiqiza kabusha amafrikhwensi aphakeme ngokunembile nangempumelelo. Kodwa ... kahle, akuyona superfluous ngisho mayelana nezici. Abantu abaningi bahlala beqaphile ngalokhu, bekholelwa ukuthi impendulo yemvamisa kufanele ifane neqhwa.

Kuphela ukuthi izici zisitshela ngokufana nesithombe esikupasipoti yendoda. Futhi nakuba umshayeli ovela ku-G4 engabonakali ekhangayo ezithombeni, ngiyakukholelwa. Udlala kahle nje, uzwakala kahle futhi akakhohlisi. Lolu uhlobo lwe-tweeter esiluthandile hhayi ukusebenza, kodwa uhlamvu.

design

Kwabaqaphi ngale ntengo, yenziwe umklamo othuthuke kakhuluyakhiwe ngezinto eziningi. Kwanele ukusho ukuthi iphaneli yangaphambili ngokwayo - eyenziwe ngepulasitiki ngokuphelele - iqukethe ukucindezela okukhethekile okuhlanu okunokuqinisa kanye nokuhlelwa okuthakazelisayo kobudlelwane babo.

Indaba ye-electronics ayithakazelisi kangako. Isignali ye-analogi ifakwa kudijithali ngesiguquli se-Texas Instruments PCM1862 bese sinikezwa ku-amplifier ye-Burr-Brown TAS5782.

Eyokugcina, njengesixazululo sedijithali ngokugcwele, ilawulwa nge-STM32 microcontroller. Futhi nguye owenza umsebenzi wokulungisa, futhi uxhumana ne-LCD ebonisa izici zalokhu kulungiswa, kanye nesishumeki esinenkinobho yokusebenza nemenyu yokuqapha.

Ekuzijwayeza

Abaqaphi bazwakala bethembekile futhi, ngokungafani nezizukulwane ezedlule ze-KRK Rokit (kodwa futhi namamodeli abiza kakhulu), ayevame ukusolwa ngokuthi "abathengi" kakhulu, banikeza isilinganiso esicacile. Yebo, uhla lwayo oluphakeme alulungile njengezinhlelo zokuqapha ezibiza kakhulu, kodwa alukukhathazi futhi lwandisa ubude bezikhathi zokulalela ngazinye.

Izici eziwumphumela zama-monitor (oluhlaza) kanye nezici zemithombo yomsindo ngamunye: i-bass reflex, i-woofer ne-tweeter. I-resonance ephawulekayo ye-parasitic ye-inverter yesigaba ku-600 kanye ne-700 Hz ibonakala kusici sisonke. I-inverter yesigaba isekela ngokuqinile i-woofer ebangeni le-50-80 Hz. I-slope eshelelayo yokuhlukaniswa kwe-crossover ukuya kumafrikhwensi aphezulu igcina ukuzwakala okuphelele kububanzi obungu-2-4 kHz uma ingakasebenzi ngokugcwele.

Njengoba ngishilo kumongo womshayeli, lokhu kunjalo abaqaphi ongabethemba. I-Bass - evamise ukuvezwa ngokuzenzela ku-KRK - lapha igcina isilinganiso esilungile seqiniso futhi isabonakala ngokucacile. Inqobo nje uma sinama-acoustics egumbi ahlelekile, i-Rokit 5 G4 izosivumela ukuthi silawule ngokugcwele yonke into engaphezu kuka-100 Hz - nakuba vele futhi inikeza ulwazi ngamaza aphansi kakhulu. Sizwa i-45Hz kalula, okuyimpumelelo enkulu kuma-monitor ahlangene.

Isifinyezo

Izizukulwane ezedlule ze-KRK Rokit zibonwa ngendlela ehlukile - abanye bayayithanda, abanye abayithandi. Umbono ojwayelekile ukuthi zinamandla "DJ" kanye "nogesi". Isimo sihlukile ngesizukulwane sesine i-Rokit futhi ngokuqinisekile nemodeli engu-5-intshi. Ungabona kahle ukuthi umsebenzi omningi osuhambile ekuthatheni umlingisi wabo we-sonic ezingeni elilandelayo. U-Rokits wakhula engenasizotha kangako.

Amashumi eminyaka okuhlangenwe nakho kanye nobuchwepheshe besimanje buye benza i-KRK yakwazi ukwenza umkhiqizo ongaqhudelana kalula neziqaphi ze-Adam, i-JBL ne-Kali Audio ezinenani elifanayo nezisebenzayo.

Uma unethuba, zama nenguqulo ye-woofer engu-XNUMX intshi no-XNUMX-intshi emagumbini amakhudlwana kanye nomsebenzi lapho udinga ukudlala kakhulu futhi ngamabhasi amaningi.
