Midiplus MI 5 - inoshanda Bluetooth monitors
Iyo Midiplus mhando iri kuramba ichizivikanwa mumusika wedu. Uye izvo zvakanaka, nekuti inopa zvigadzirwa zvinoshanda nemutengo unonzwisisika. Zvakadai sema compact monitors anotsanangurwa pano.
M.I. shanu veboka magudzanzwi ane nzira mbiriumo isu tinodyisa chiratidzo kune imwe chete yekutarisa. Tichazviwanawo maari volume control uye chinja simba. Iyi mhinduro yakavakirwa pane inoshanda-passive chimiro, umo zvese zvemagetsi, kusanganisira magetsi amplifiers, anoiswa mune imwe yekutarisa, kazhinji kuruboshwe. Yechipiri ndeyekungoita, inogamuchira chiratidzo chegudzanzwi kubva kune inoshanda cheki, ndiko kuti, akati wandei kana makumi emavolts.
Kazhinji munyaya iyi, vagadziri vakawanda vanoenda kune nzira iri nyore, vachibatanidza vatauri netambo imwe chete. Izvi zvinoreva kuti iyo yekutarisa haisi mbiri-nzira (ine akasiyana amplifiers for i), asi Broadband, uye kupatsanurwa kunoitwa passively uchishandisa nyore crossover. Izvi zvinowanzouya pasi kune imwechete capacitor nekuti ndiyo iri nyore uye yakachipa nzira ye "kuparadzanisa" ma frequency epamusoro kubva kune yese audio spectrum.
Chokwadi maviri chiteshi amplifier
Munyaya ye M.I. shanu tine mhinduro yakasiyana zvachose. Iyo passive yekutarisa yakabatana kune inoshanda ina-waya tambo, uye ichi chiratidzo chechokwadi chekuti monitors inopa inoshanda bandwidth kugovera uye inoparadzanisa amplifiers ye uye. Mukuita, izvi zvinoturikira mukugona kweiyo yakanyatso kutenderera frequency kuumbwa uye sefa mutsetse muchinjika uye, semhedzisiro, yakawedzera kudzora kudzokororwa kwekiyi ruzha rweboka kubva kumharadzano frequency.
Mumwe munhu angapopota achiti: “Zvinoita musiyano wei, nekuti mamonitor aya anodhura asingasviki 700 zł - pamari iyi hapana mashura! Uyezve iyo Bluetooth! Mune dzimwe nzira, izvi zvakarurama, nokuti nokuda kwemari iyi zvakaoma kutenga zvinhu ivo pachavo, tisingatauri tekinoroji yese kumashure kwevatariri. Uye zvakadaro! Humwe hwemashiripiti ekuFar Eastern, kugona kwakasarudzika kwekugadzirisa uye optimization yemitengo yekugadzira, isinganzwisisike kune veEurope, yakabatsira kune chokwadi chekuti pamari iyi tinowana inonakidza seti yekuteerera kuimba yekumba kana multimedia chiteshi.

Chiratidzo chinogona kuiswa mumutsara - kuburikidza Yakaremara 6,3 mm TRS mapindiro uye isina kuenzana RCA uye 3,5mm TRS. Iyo yakavakirwa-mukati Bluetooth 4.0 module inogona zvakare kuve sosi, uye iyo yakazara chiratidzo nhanho kubva kune aya masosi inogadziriswa uchishandisa potentiometer pane yekumashure pani. Iyo switchable shelving sefa inotaridza mwero weakakwira frequency kubva -2 kusvika +1 dB. Iwo emagetsi akavakirwa paanalogi masekete., maviri amplifier modules anoshanda mukirasi D, uye switching power supply. Iyo yekuvaka mhando uye kutarisisa kune zvakadzama (senge acoustic yakasarudzika yeanotaura Jacks uye TPCs) inotaura kune yakakomba maitiro evagadziri kune dingindira.
Iwo mamonitor anotengeswa semaviri, anosanganisira anoshanda uye akasarudzika seti, akabatanidzwa ne 4-waya mutauri tambo.
Pamusoro pemhando nhatu dzekupinza mutsara, vatariri vanopa kugona kutumira chiratidzo kuburikidza neBluetooth.
monitors iva ne-bass-reflex dhizaini ine yakananga kuburitsa kune kuseri kwepaneru. Nekuda kwekushandiswa kwediaphragm 5-inch ine diaphragm yakakura zvakaringana, zvaive zvakafanira kushandisa kesi ine hudzamu hwakati kurei kupfuura yaizoratidzika kubva pachiyero chezviyero. Iyo passive monitor haina zvemagetsi, saka vhoriyamu yayo chaiyo yakakura kupfuura yeanoshanda monitor. Izvi zvakafungwawo, zvichiripa zvakakwana izvi nekuwedzera huwandu hwekunyorovesa zvinhu.
Iyo dhayamita yekushanda yewoofer diaphragm ndeye 4,5 ″, asi zvinoenderana nefashoni yazvino, mugadziri anoikodzera se5 ″. Woofer inoiswa mumashure mepaneru yekumberi ine profiled edges. Iyi inonakidza uye isingawanzo dhizaini iyo inokutendera iwe kuti uwedzere acoustic dhayamita yeiyo sosi yepasi uye yepakati ma frequency. Iyo tweeter zvakare inonakidza, ine 1,25 ″ dome diaphragm, iyo isina kana analogues mumutengo uyu.

inoita basa rayo kana ichiridza bass kubva pa100 Hz zvichikwira, uye muhuwandu hwe50 ... 100 Hz inotsigirwa noushingi neyakagadzirirwa chaizvo. phase inverter. Iyo yekupedzisira, yakapihwa zviyero zvemonitor, yakanyarara uye haiunze kukanganisa kwakakosha. Zvese izvi zvinotaura nezve kusarudzwa kwakaringana kwezvinhu uye kufunga, dhizaini yakagadzirwa.
Iyo frequency mhinduro yemonitor, uchifunga nezvezvinzvimbo zvitatu zvekusefa kwepamusoro. Pazasi pane maitiro eiyo 55th uye 0,18th harmonics kune ese mafirita marongero. Avhareji THD ndeye -XNUMXdB kana XNUMX% - mhedzisiro yakanaka kune mamonitor madiki akadaro.
Pakati pemafrequency, inotanga kurasikirwa nekubudirira kwayo, iyo inodonha ne1 dB pa10 kHz. Pano iwe unogara uchida kuwana yakaringana chiyero pakati pezvinhu zvakaita semutengo, bass kugadzirisa mhando uye kukanganisa level. Ichi chiitiko chaicho chekuenzanisa pamutsetse wakanaka, uye kunyangwe vagadziri vanozivikanwa sevatungamiriri havawanzo kubudirira mune iyi art. Munyaya yeMI5, handina chimwe chandinogona kuita kunze kwekuratidza ruremekedzo rwangu kune basa rakaitwa nevagadziri, avo vaiziva chaizvo kuti chii uye kuti vaida sei kubudirira.
Frequency maitiro ega ega masaini masosi: woofer, tweeter uye bass reflex. Neunyanzvi akasarudzwa akapatsanura paramita, emhando yepamusoro madhiraivha uye ine muenzaniso dhizaini yebass-reflex port inoita kuti monitor inzwike inonakidza.
Kuparadzaniswa kwefrequency ndeye 1,7 kHz uye mutyairi anosvika pakubudirira kwakazara pa3 kHz. Kutenuka kwemafirita ecrossover kwakasarudzwa zvekuti kurasikirwa kwese kwekuita basa pacrossover frequency kwaingova 6 dB. Uye sezvo uyu uri iwo chete mutengo waunofanirwa kubhadhara kune yakatsetseka kugadzirisa mafrequency anosvika makumi maviri kHz, ini ndinoda zvinhu zvakadaro.
Kuenzanisa kwehunhu uye harmonic kukanganisa kana uchiridza chiratidzo kuburikidza nemutsara wekupinza uye Bluetooth port. Kunze kwekunonoka kunoonekwa mukupindurwa kwemhinduro, magirafu aya anenge akafanana.
Handizive kuti vagadziri vakawana mutyairi uyu kubva kupi, asi iyi ndeimwe yeanonyanya kufadza compact dome tweeters andati ndambonzwa. Sezvo iine dhayamita ye1,25 ″, isingawanzo nyangwe mune izvo zvinonzi mamonitor ehunyanzvi, inogona kutora nyore kugadzirisa kubva pa1,7kHz ichichengeta avhareji yechipiri harmonic level ye -50dB inoenderana neiyo yakakosha frequency (tiri kutaura nezve 0,3 chete, XNUMX%). Masonani anobuda kupi? Munzira yekugovera, uye mukuona kwedesktop hunhu hwema monitors aya, hazvina basa zvachose.
Pakuita
Inzwi reMI 5 rinotaridzika rakasimba, kunyanya maererano nemutengo uye kushanda. Zvinonzwika zvine hushamwari, zvinonzwisisika, uye kunyangwe zvakaderera zvepakati-renji kushanda zvakanaka, zvinomiririra kupenya kwedivi reruzha, pamwe kunyangwe kupenya zvakanyanya. Pane mhinduro yeizvi - isu tinoisa iyo yepamusoro sherufu sefa kusvika -2 dB, uye iwo mamonitor pachawo akaiswa ku "zvishoma divergent squint". Chero bedzi kamuri yacho isiri kupuruzira neyechinyakare imba studio 120-150Hz, tinogona kutarisira yakavimbika yekuteerera ruzivo panguva yekuronga uye yekutanga kugadzira.
Kutamba kweBluetooth kwakada kufanana nekutamba kwetambo, kunze kwekunge 70ms yekunonoka kutapurirana. Iyo BT port inonzi MI 5, ichipa 48kHz sampuli chiyero uye 32-bit inoyangarara poindi resolution. Kunzwa kweBluetooth module kwakawedzera zvakanyanya nekuisa 50 cm antenna mukati memonitor - ichi ndicho humwe humbowo hwekuti vagadziri vakaita zvakakomba sei basa ravo.
Summation
Zvinoshamisa kuti, kupihwa mutengo weaya monitors uye mashandiro avo, zvakaoma kutaura nezve chero kukanganisa. Ivo zvechokwadi havazoridza zvine ruzha, uye kurongeka kwavo hakugutse zvinodikanwa zvevagadziri vanofarira kutonga kwakazara pamusoro pezviratidziro uye kusarudzwa kwezviridzwa. Iyo yakaderera midrange inoshanda haisi yemunhu wese, kunyanya kana zvasvika kune vocals uye acoustic zviridzwa. Asi mumhanzi wemagetsi, basa iri harisisina kukosha. Ini ndinogona kufunga kuti senitivity control uye switch yemagetsi iri kumashure, uye tambo yemagetsi yakavharirwa zvachose mucherechedzo yekuruboshwe. Nekudaro, ichi hachisi chinhu chinokanganisa kushanda kweMI 5 uye ruzha rwayo.
Nemutengo wavo, kugadzirwa kwakanaka, uye kutarisa kune sonic ruzivo mukutamba, ivo vakakwana pakutanga mimhanzi yako-yekutamba mutambo. Uye kana isu tichikura kubva kwavari, ivo vachakwanisa kumira pane imwe nzvimbo mukamuri, vachikubvumidza iwe kuridza mimhanzi kubva kune yako smartphone.
