Sravana Sameeralu 5 G4 Studio

Iyo KRK Rokit pasina mubvunzo ndeimwe yeanonyanya kufarirwa mamonitor pasirese, anoshandiswa mudzimba dzekurekodha studio uye nekumwe. G4 chizvarwa chavo chechina. Shanduko dziri muG3 dzakakura zvekuti tinogona kutaura nezve chigadzirwa chitsva chose.

Kunyangwe boka remamonitor rakasanganisirwa mukati G4 series tichawana mhando ina, ndakasimbirira kuti ndinoda kuyedza zvishomaс 5" woofer.

Chekutanga, ini handitendi mune yakakwana bass kuberekana mumakamuri madiki umo bhajeti padyo nemunda mamonitor anonyanya kushandiswa. Kuwedzera dhayamita yewoofer, iyo dzimwe nguva inosanganiswa nekudzikisa yakaderera frequency inobatwa nemonitor, haiite pfungwa yakawanda mumamiriro ezvinhu akadaro, kunze kwekupa fungidziro yepasi bass. Nekudaro, bass rakadaro rinoramba risingadzoreki uye zvakanyanya psychoacoustic phenomenon kupfuura mashoko akavimbika anonzwika.

Iyo DSP block inodzorwa neyemvura crystal kuratidza uye encoder ine bhatani basa. Iyo encoder pachayo zvakare inobvumidza iwe kuti ugadzirise iyo yekuisa senitivity yevatariri.

Chikonzero chechipiri ini ndinogara ndichisarudza 5-6 ″ monitors imhaka yekuti inodiwa kune makuru setups. yakaderera crossover frequency, iyo inotungamirira kuderera kwekubudirira kwevatariri maererano nechiyero.

Izvi hazvirevi kuti mikana yeimwe kunze kwe5-inch kits haina kubviswa. Vazhinji vanosarudza ruzha rwezvinomwe kana masere, uye ini handisati ndamboshamisika. Iwo ane ruzha, ane simba uye anobereka mabhesi zvakanyanya. Nekudaro, kana ndichifanira kusarudza, ini ndinowanzo sarudza Fives nekuti ivo vanove vanomiririra zvakanyanya kutevedzana kwese uye vane zvakawanda zvekutaura nezve pfungwa iri shure kwavo. Zvinoita sekuti mune iyi kesi handina kukwanisa kuita chikanganiso ...

Mibvunzo yezvemari

Makore mashoma apfuura, paakabvunzwa kuti zvii monitors kusvika ku1500 PLN pamurume nemukadzi Ndinogona kukurudzira, mhinduro chete yakanga iri kunyemwerera. Zvino, pasina kuzeza, ndinoti munhu wese. Misiyano pakati pemasisitimu akadai saAdam Audio T5V, JBL 306P MkII, Kali Audio LP6 uye pakupedzisira KRK Rocket 5 G4 ivo vanoyevedza mune zvakasikwa. Kutenga chero ipi zvayo hakuzove kukanganisa chero bedzi tichiziva kuti ndeyei pedyo nemamonitor emunda chinangwa chebasa rekugadzira uye premixkwete yekusanganisa nehunyanzvi.

Mutengo: PLN 790 (imwe neimwe); Mugadziri: KRK Systems, www.krksys.com Kugovera: AudioTech, www.audiotechpro.pl

Muzviitiko zviviri zvekupedzisira, iwe unofanirwa kutanga nePDU (kamuri, ruzivo, hunyanzvi), uye ipapo mamonitor awakasarudza anozojekesa ega. Uye ini ndinovimbisa kuti havazove muhuwandu hwekusvika PLN 1500. Nekudaro, kune masitudiyo ekurekodha epamba nepurojekiti, pamwe nerudzi rwebasa ratinowanzo kuita munzvimbo dzakadai, mamonitor aya anove akarurama. Pavari isu tichawedzera yedu yega PDU factor.

Vashanduri

Rokit 5 G4 inzira mbiri-mamonitor, inoshanda, inoshanda mu-bi-amp modhi uye yakavakirwa paMDF bass-reflex cabinet - chaizvo senge ruzhinji rweseti yerudzi urwu. Saka vakasiyana sei nevamwe? Yellow aramid driver diaphragms? Hongu, ibhizinesi kadhi reKRK, sezvakaita logo yakavhenekerwa. Iyo phase inverter inomhanya ichitevedza mupendero wezasi wepaneru yekumberi uye ine contoured edges. Hongu, ichi chinhu chinonakidza kwazvo. Chinotonyanya kufadza ndechekuti bass-reflex tunnel ine yakasarudzika dhizaini - yakakomberedzwa muchimiro chemavara akatenderedzwa L uye yakareba kwazvo, ichipera inenge hafu yehurefu hwemonitori.

About application high frequency converter zvimwe zvakanaka kutaura. Uyu mutyairi akagadzirwa zvakanaka ane hombe ferrite magineti uye dome rekugadzira rinonyorovesa resonances zvakanaka. Iyo ine yakaderera kwazvo yekukanganisa nhanho uye yakanakisa yakanangana, iyo mune acoustically yakanaka kamuri inovimbisa nyore kumira kwezvinyorwa uye kugadzikana kwavo mune panorama.

Iwo mafirita anowanikwa muchikamu cheEQ anoshanda senge presets: ina kune yakaderera frequency uye ina yeakakwira mafrequency. Muzviitiko zvese izvi, yechitatu kuseta inodzima kusefa. Kune yakaderera frequency, iyo yakaenzana inosanganisira 60 Hz masherufu sefa uye 200 Hz bhendi bhendi sefa, uye kune yakakwirira frequency, gumi kHz shelving sefa uye 10 kHz bandpass sefa.

Inonzwika zvakanaka - yakajeka, isina ruzha, nemazvo uye zvinobudirira inoburitsa ma frequency epamusoro. Asi ... zvakanaka, hazvina superfluous kunyangwe maererano nehunhu. Vanhu vazhinji vanoramba vakangwarira pamusoro peizvi, vachitenda kuti frequency mhinduro inofanira kufanana nechando.

Chete izvo hunhu hunotiudza chaizvo sezvakaita mufananidzo uri mupasipoti yemurume. Uye kunyangwe mutyairi kubva kuG4 asingataridzi anokatyamadza pamifananidzo, ndinozvitenda. Anongotamba zvakanaka, anonzwika zvakanaka uye haabiridzire. Iyi ndiyo mhando ye tweeter yatinofarira kwete yekuita, asi ye mutambi.

Kune monitors pamutengo uyu, yakagadzirwa dhizaini yepamusoroyakagadzirwa nezvinhu zvakawanda. Zvakwana kutaura kuti pani yepamberi pachayo - yakanyatsogadzirwa nepurasitiki - ine shanu dzakanyanya kudzvanywa nekusimbisa uye inonakidza kuronga kwehukama hwavo.

Nyaya yemagetsi haisi shoma inonakidza. Iyo analogi siginecha inogadziriswa kuburikidza neTexas Instruments PCM1862 inoshandura uye yobva yapihwa kuBurr-Brown TAS5782 amplifier.

Iyo yekupedzisira, semhinduro yakazara yedhijitari, inodzorwa kuburikidza neiyo STM32 microcontroller. Uye ndiye anoita basa rekugadzirisa, zvakare kupindirana neLCD kuratidza maitiro ekugadzirisa uku, uye encoder ine bhatani rekushanda nekutarisa menyu.

Pakuita

Iwo mamonitor anonzwika akatendeseka kwazvo uye, kusiyana nezvizvarwa zvakapfuura zveKRK Rokit (asi zvakare anodhura mamodheru), ayo aiwanzopomerwa kuve zvakare "vatengi", inopa. chiyero chinoratidza. Ehe, huwandu hwayo hwepamusoro hauna crisp seanodhura mamonitor masisitimu, asi haakunetese uye anowedzera hurefu hwezvikamu zvekuteerera zvega.

Izvo zvinokonzeresa hunhu hwemamonitor (girinhi) uye hunhu hwemunhu wega ruzha masosi: bass reflex, woofer uye tweeter. Iyo inooneka parasitic resonance yechikamu inverter pa600 uye 700 Hz inoratidzwa mune yakazara hunhu. Iyo phase inverter inotsigira zvakasimba iyo woofer muhuwandu hwe50-80 Hz. Iyo yakatsetseka inotsvedza yekuparadzaniswa kwecrossover yakanangana nepamusoro mafrequency inochengetedza kunzwika kwakanyanya mu2-4 kHz renji kana isati yanyatsoshanda.

Sezvandakataura mumamiriro emutyairi, izvi ndizvo monitors iwe unogona kuvimba. Bass - inowanzofumurwa muKRK - pano inochengetedza zviyero zvakaringana kune chokwadi uye ichiri kuoneka zvakajeka. Chero bedzi isu tine yakarongeka kamuri acoustics, iyo Rokit 5 G4 ichatibvumidza kunyatso kudzora zvese pamusoro pe100 Hz - kunyangwe hazvo ivo vachipawo ruzivo pane yakaderera frequencies. Isu tinonzwa 45Hz tisingashande, inova budiriro yeakadai compact monitors.

Summation

Zvizvarwa zvakapfuura zveKRK Rokit zvinoonekwa zvakasiyana - vamwe vanozvida, vamwe havazvide. Maonero akazara ndeokuti ivo vane simba "DJ" uye "electronic". Mamiriro acho akasiyana nechizvarwa chechina Rokit uye zvechokwadi ane 5-inch modhi. Iwe unogona kuona zvakajeka kuti basa rakawanda rakapinda mukutora hunhu hwavo hwe sonic kune chinhanho chinotevera. Rokits akakura asina mwero.

Makumi emakore eruzivo uye tekinoroji yemazuva ano yakaita kuti KRK igadzire chigadzirwa chinogona kukwikwidza zviri nyore nemutengo wakafanana uye unoshanda wakafanana Adam, JBL uye Kali Audio monitors.

Kana ukawana mukana, edzawo XNUMX-inch uye XNUMX-inch woofer shanduro kumakamuri akati kurei uye kubasa kwaunoda kuridza ruzha uye nemamwe mabhasi.
