I-PreSonus Eris E4.5 BT - iziqapha ezihlangene zokulalela

I-Eris E4.5 BT inguqulo enikwe amandla i-Bluetooth yama-compact monitors e-Eris E4.5 eyethulwe ngaphambilini, anikela cishe ngama-specs afanayo ngokuya ngokusebenza.

Ukube iNkosi uHarald, eyabhapathiza iDenmark cishe ngesikhathi esifanayo noMieszko/Mesiko/Dagome (susa ngokufanelekile) endaweni kamuva eyabizwa ngokuthi iPoland, yayazi ukuthi yayizobizwa ngokuthi i-Blue Tooth, khona-ke ezizukulwaneni ezingamakhulu amathathu kamuva lesi sidlaliso sasizoba. igama lokudluliselwa kobuchwepheshe obungenawaya idatha, mhlawumbe ngabe uwele emcabangweni ojulile. Ikakhulukazi ngenxa yokuthi isifiso esishiwo kuye namuhla "sokuhlanganisa" abantu baseScandinavia sasingenalo kancane ukuqonda kwesimanje komsebenzi onjalo.

Nokho, ake sishiye ukucabanga ngalezi zindaba kosomlando, abathi, bechaza lezo zindawo nezikhathi, basungule okungaphezu kwamaqiniso ombuso. Okwethu I-Bluetooth kuzoba iphrothokholi eyasetshenziswa kumamonitha I-PreSonus Eris E4.5 BTfuthi empeleni eyodwa kuphela yepheya ngalinye, ngoba enye ayisebenzi ngokuphelele. Ngaphezu kwalokho, i-Bluetooth iyisengezo kuphela endleleni evamile yokuletha izimpawu zomsindo, i.e. ngokusebenzisa amasokhethi nangefomu le-analog.

Esinye seziqapha kusethi siyasebenza futhi sithumela isignali yesipika kwesinye, esihlala siyisakhiwo sokwenza (ngaphandle kwezikhulumi kanye ne-crossover elula, ayinakho i-electronics).

design

Idizayini yama-monitor ijwayelekile kumakhithi e-multimedia ahlangene - eyodwa iqukethe zonke izixhumi nazo zonke izinto zikagesi, kanti enye iqukethe imonitha yokwenziwa kuphela, lapho siphakela khona isignali yesipikha esisuka esisekelweni. Zombili zinesakhiwo esimise okwe-x futhi zinezinhlangothi ezimbili, nakuba zingasebenzi kumodi. Lokhu kusho ukuthi isignali isetshenziswa kokubili ama-transducers ngesikhathi esifanayo, futhi ukuhlukaniswa kwama-frequencies aphezulu kwenziwa ngokuzenzakalelayo ngokusebenzisa i-crossover elula. Kunjalo-ke iningi lezinto ezibizwa nge-audiophile kits, ngakho-ke akukho lutho olungalungile ngalokho. Ngaphezu kwalokho, ngezinye izikhathi ama-crossovers alula we-6db akuvumela ukuthi uthole imiphumela yokugcina ethakazelisa kakhulu, yebo, kuncike ekukhetheni okuhle kwabashayeli.

Ukusebenza okuwumphumela kwama-monitor kuzilungiselelo ezimaphakathi nezidlulele zezihlungi eziphansi neziphezulu zamashelufu.

Futhi kulokhu, ine-diaphragm elukiwe eqinile enobubanzi obungu-4,5 ″ kanye nokuchezuka okukhulu kakhulu kobukhulu obunjalo, kanye ne-intshi engu-1 enedome lendwangu embozwe ngokucophelela ngensimbi yensimbi. Ephaneli elingaphambili le-monitor esebenzayo kukhona isilawuli sevolumu eyinhloko, inkinobho yamandla, okokufaka kwe-stereo yangaphandle kanye nokukhishwa kwe-headphone, izixhumi ezimbili zokugcina ziyi-3,5 mm TRS; isignali esetshenziswe ku-n ifinyezwa ngesignali esetshenziswe kokufakwayo kuphaneli yangemuva noma nge-Bluetooth; ngokulandelayo, ngemva kokufaka ipulaki esokhethi, izikhulumi ziyacishwa.

Izilawuli ezisesigabeni ziphansi (100 Hz) nezihlungi zamashelufu eziphezulu (10 kHz) ezisebenza ebangeni elingu-±6 dB, ezikuvumela ukuthi ulungise umsindo ekamelweni lakho noma okuncamelayo umsebenzisi.

Izici zezingxenye ngazinye zesethi (, kanye i-twitter) ngokumelene nesizinda sezici eziwumphumela zayo yonke. Kukhona i-resonance eqinile ye-parasitic, echithwa ngokuphumelelayo kusici esiwumphumela.

Ukwenza kusebenze uxhumano lwe-Bluetooth kwehla ekwenzeni kusebenze le modi kudivayisi yokudlulisa (imvamisa i-smartphone noma ikhompyutha ephathekayo), ucindezela inkinobho kumonitha we-PreSonus, nokuqinisekisa okukhethiwe kusidlulisi. Imonitha ikhumbula imithombo emibili yesiginali ehlukene, ngakho-ke ingasebenza ngokushintshana nama-transmitters amabili.

Isethi esebenzayo yesistimu ye-E4.5 BT inikwe amandla ngokuqondile kusuka kumapayipi futhi ingasebenza nge-voltage kusuka ku-100 kuya ku-240 V. Umzimba wabaqaphi wenziwe nge-MDF, futhi iphaneli yangaphambili yenziwe ngepulasitiki ebekwe ku-MDF. ibhodi. Ifaka ikhebuli yamandla, ikhebuli yesipika (2m), ikhebuli ye-TRS/TRS 3,5mm (1,5m) nekhebula le-RCA/TRS 3,5mm (1,5m). Kukhona nebhukwana lomsebenzisi kanye nezinyawo eziyisishiyagalombili ze-silicone ezingafakwa ngaphansi kwezipikha.

Izici ezihlanganisa ukuhlanekezela kwe-harmonic. Njengoba kuvamile ngezipikha ezincane, ukuhlanekezela kukhulu kakhulu kumaza omsindo.

Ekuzijwayeza

Ngokwehla kokusebenza kahle kwama-decibel ayi-10, abaqaphi baphatha amasiginali ukusuka ku-75 Hz ukuya ngaphezulu kuka-20 kHz, futhi bakwenza ngobuqotho kakhulu. Ngenxa yobukhulu bomhubhe, umsindo nokuphazamiseka kungeniswa kuwo nakanjani, okuzozwakala kubhendi engu-60-100 Hz lapho kudlalwa isiginali ye-sinusoidal. Ngakho-ke, ukusebenza ngomsindo wonyawo ngeke kube indawo eyinhloko yebhasi ye-E4.5 BT. Ibanga phakathi kwezikhungo ze-acoustic zama-transducers ngu-10 cm, ngakho-ke ebangeni le-6,8 kHz kukhona ukwephulwa kwezimpawu zokucubungula ezihambisana nokusetshenziswa kwesignali ye-wideband.

Naphezu kwamaphutha asobala ekwakhiweni kwabaqaphi, balinganisela ngokufanele ngokwentengo, ikhwalithi kanye nokusebenza. Ukuba khona kwephrothokholi ye-Bluetooth ekusebenzeni kuvele kulungele kakhulu - uma sifuna ukudlala umculo esisetshenziswa esiphathwayo, asinciki kukhebula kuphela.

Isifinyezo

Ukuncintisana kwemakethe ye-Eris E4.5 BT ikakhulukazi I-Maki CR4/CR5 BT (nezinguqulo zakamuva ze-CR-X) kanye I-JBL 104-BT. Njengoba ubona, abanye abakhiqizi abahlakaniphile kakhulu uma kuziwa ekudaleni abaqaphi ngoxhumo lwe-Bluetooth - njengokungathi bezwa ukuthi ukuqaliswa kwalesi simiso somthetho kunikeza abaqaphi "ukuthengwa" okuqondile, kubukela phansi ubuchwepheshe babo.

Yebo, ukuguqula umsindo usuka ku-AC uye kudijithali, ukubhala ngekhodi ngesishumeki esicindezela idatha, ukudluliswa komsakazo, ukuqopha, futhi ekugcineni kucutshungulwe kwifomu le-analogi ngeke kwenze lo msindo ube ngcono kunokumane udluliselwe ngekhebuli.

Awekho ama-agumenti aqinile angaphikisa inzuzo yekhwalithi yekhebula phezu kwesiteshi somsakazo wedijithali. Kepha ake sibhekane nakho, singathini mayelana nama-compact monitors - ngenkathi encoma ama-bass awo, ukuphakama okucwebezelayo, ukusebenza kahle nokusobala, awakwazi ukuzwakala enembile uma eqhathaniswa nabaqaphi be-studio abahlanzekile. Futhi lokhu akulona iphuzu, kodwa kunalokho ekulingiseni indlela umculo wethu ozoziphatha ngayo kumasethi anjalo (futhi ngokuvamile abuthakathaka kakhulu) ozodlalwa kuwo kaningi. Futhi kulo mongo, ukuba khona kwe-Bluetooth ku-Eris E4.5 BT kwandisa kuphela ukwethembeka kwabo.
