Kuyang'anira KRK Rokit 5 G4 Studio

KRK Rokit mosakayikira ndi amodzi mwa oyang'anira otchuka padziko lonse lapansi, omwe amagwiritsidwa ntchito m'ma studio ojambulira kunyumba ndi kupitirira apo. G4 ndi m'badwo wawo wachinayi. Kusintha kwa G3 ndi kwakukulu kotero kuti tikhoza kulankhula za chinthu chatsopano.

Ngakhale gulu la oyang'anira likuphatikizidwa Zithunzi za G4 tidzapeza zitsanzo zinayi, ndinaumirira kuti ndikufuna kuyesa osacheperaс 5 "wofewa.

Choyamba, sindimakhulupirira kuti mulingo woyenera kwambiri wa bass ukhale m'zipinda zing'onozing'ono momwe bajeti pafupi ndi malo owunikira amagwiritsidwa ntchito kwambiri. Kuchulukitsa mainchesi a woofer, omwe nthawi zina amagwirizanitsidwa ndi kutsika kwafupipafupi komwe kumayendetsedwa ndi polojekiti, sikumveka bwino mumikhalidwe yotere, kupatula kupereka chithunzi cha mabasi otsika. Komabe, bass yotereyi imakhalabe yosalamulirika komanso yochulukirapo psychoacoustic phenomenon kuposa chidziwitso chodalirika.

Chotchinga cha DSP chimayang'aniridwa ndi chiwonetsero chamadzi amadzimadzi ndi encoder yokhala ndi batani. Encoder palokha imakulolani kuti musinthe kukhudzidwa kwa zowunikira.

Chifukwa chachiwiri chomwe ndimasankha nthawi zonse zowunikira 5-6 ndi chifukwa ndizofunikira pakukhazikitsa kwakukulu. kutsika kwafupipafupi kwa crossover, zomwe zimabweretsa kuchepa kwa mphamvu ya owonera pamiyeso.

Izi sizikutanthauza kuti mwayi wa zida zina za 5-inch sizimachotsedwa. Ambiri amakonda phokoso lachisanu ndi chiwiri kapena eyiti, ndipo sindikudabwa konse. Amamveka mokweza kwambiri, amasinthasintha komanso amabala ma bass bwino kwambiri. Komabe, ngati ndiyenera kusankha, nthawi zambiri ndimasankha Fives chifukwa iwo adzakhala oimira kwambiri mndandanda wonse ndipo ali ndi zambiri zonena za lingaliro lomwe liri kumbuyo kwawo. Zikuwoneka kuti pakadali pano sindinalakwitse ...

Mafunso azachuma

Zaka zingapo zapitazo, atafunsidwa zomwe oyang'anira mpaka PLN 1500 banja lililonse Ndikhoza kulangiza, yankho lokha linali kumwetulira. Tsopano, popanda kukayikira, ndikunena kuti aliyense. Kusiyana pakati pa machitidwe monga Adam Audio T5V, JBL 306P MkII, Kali Audio LP6 ndipo potsiriza KRK Rocket 5 G4 ndi zokongola m'chilengedwe. Kugula aliyense wa iwo sikudzakhala kulakwitsa bola ife tikudziwa chomwe chiri pafupi ndi oyang'anira minda cholinga ntchito yokonza ndi premixosati kwa akatswiri kusakaniza ndi ukadaulo.

Mtengo: PLN 790 (iliyonse); Wopanga: KRK Systems, www.krksys.com Kugawa: AudioTech, www.audiotechpro.pl

M'magawo awiri omaliza, muyenera kuyamba ndi PDU (chipinda, chidziwitso, luso), ndiyeno oyang'anira omwe mwasankha adzadziyeretsa okha. Ndipo ndikutsimikizira kuti sadzakhala m'gulu la PLN 1500. Komabe, kwa situdiyo zojambulira kunyumba ndi polojekiti, komanso mtundu wa ntchito zomwe timakonda kuchita m'malo oterowo, oyang'anira awa adzakhala oyenera. Ndi pa iwo kuti tidzawonjezera PDU yathu.

Otembenuza

Rokit 5 G4 ndi oyang'anira njira ziwiri, akugwira ntchito, akugwira ntchito mu bi-amp mode ndipo amachokera ku MDF bass-reflex cabinet - chimodzimodzi monga kuchuluka kwa magulu amtunduwu. Ndiye amasiyana bwanji ndi ena? Zithunzi za Yellow Aramid Driver Diaphragms? Inde, ndi khadi la bizinesi la KRK, monganso chizindikiro chowala. The inverter gawo amayenda m'mphepete m'munsi mwa gulu kutsogolo ndipo ali m'mphepete contoured. Inde, ichi ndi chinthu chosangalatsa kwambiri. Chochititsa chidwi kwambiri ndi chakuti msewu wa bass-reflex uli ndi mapangidwe apadera - umakhala wopindika ngati chilembo chozungulira L ndipo ndi wautali kwambiri, umatha pafupifupi theka la kutalika kwa polojekiti.

Za ntchito mkulu pafupipafupi Converter zina zabwino kunena. Uyu ndi dalaivala wopangidwa bwino wokhala ndi maginito akulu a ferrite komanso dome lopangidwa lomwe limanyowetsa bwino. Ili ndi mulingo wokhotakhota wotsika kwambiri komanso wowongolera bwino kwambiri, womwe muchipinda chabwino kwambiri umatsimikizira kukhazikika kwa magwero ndi kukhazikika kwawo panorama.

Zosefera zomwe zikupezeka mu gawo la EQ zimagwira ntchito ngati zokonzeratu: zinayi pama frequency otsika ndi anayi pama frequency apamwamba. Muzochitika zonsezi, makonda achitatu amalepheretsa kusefa. Pama frequency otsika, chofananira chimaphatikizapo 60 Hz shelving fyuluta ndi 200 Hz band pass pass, komanso ma frequency apamwamba, 10 kHz shelving fyuluta ndi 3,5 kHz band pass.

Zikumveka bwino - zowonekera, zopanda phokoso, molondola komanso moyenera zimatulutsa ma frequency apamwamba kwambiri. Koma ... chabwino, sizowonjezera ngakhale malinga ndi mawonekedwe. Anthu ambiri amakhalabe tcheru pa izi, pokhulupirira kuti kuyankha pafupipafupi kuyenera kukhala kofanana ndi ayezi.

Kungoti mawonekedwe amatiuza ndendende monga chithunzi cha pasipoti ya bamboyo. Ndipo ngakhale dalaivala wochokera ku G4 sakuwoneka wochititsa chidwi pazithunzi, ndikukhulupirira. Amangosewera bwino, akumveka bwino komanso samabera. Uwu ndi mtundu wa tweeter womwe sitikonda osati pakuchita, koma chifukwa khalidwe.

kupanga

Kwa oyang'anira pamtengo uwu, adapangidwa mapangidwe apamwamba kwambirizopangidwa ndi zinthu zambiri. Zokwanira kunena kuti gulu lakutsogolo lokha - lopangidwa ndi pulasitiki - lili ndi makina asanu apadera olimbikitsira komanso makonzedwe osangalatsa a maubwenzi awo.

Mlandu wamagetsi ndi wosangalatsanso. Chizindikiro cha analogi chimasinthidwa pakompyuta kudzera mu chosinthira cha Texas Instruments PCM1862 kenako ndikuperekedwa ku Burr-Brown TAS5782 amplifier.

Yotsirizirayi, ngati njira yothetsera digito, imayendetsedwa kudzera pa STM32 microcontroller. Ndipo ndi iye amene amachita ntchito yokonza, komanso kuyanjana ndi LCD kusonyeza makhalidwe a kukonzedwa uku, ndi encoder ndi batani ntchito ndi polojekiti menyu.

Pochita

Oyang'anira amamveka oona mtima kwambiri ndipo, mosiyana ndi mibadwo yakale ya KRK Rokit (komanso zitsanzo zodula kwambiri), zomwe nthawi zambiri zimatsutsidwa kuti ndizo "ogula", amapereka. muyeso wofotokozera. Inde, utali wake siwowoneka bwino ngati makina owonera okwera mtengo, koma samakutopetsani komanso amakulitsa utali wa magawo omvera.

Zotsatira zake za oyang'anira (zobiriwira) ndi mawonekedwe amtundu wamtundu wina: bass reflex, woofer ndi tweeter. A noticeable parasitic resonance of the phase inverter pa 600 ndi 700 Hz ikuwonekera mu mawonekedwe onse. Inverter ya gawo imathandizira kwambiri woofer mumtundu wa 50-80 Hz. Kutsetsereka kosalala kwa kupatukana kwa crossover kupita ku ma frequency apamwamba kumasunga kumveka bwino mumtundu wa 2-4 kHz pomwe sikunagwire ntchito.

Monga ndidanenera mumayendedwe oyendetsa, izi ndi oyang'anira omwe mungawakhulupirire. Bass - yomwe nthawi zambiri imawululidwa ku KRK - apa imasunga zolondola pazowona ndipo ikuwoneka bwino. Malingana ngati tili ndi ma acoustics adongosolo m'chipinda, Rokit 5 G4 itilola kuti tizitha kuwongolera chilichonse chomwe chili pamwamba pa 100 Hz - ngakhale kuti amaperekanso chidziwitso pamayendedwe otsika kwambiri. Timamva 45Hz mosavutikira, zomwe ndikuchita bwino kwa oyang'anira ophatikizika.

Chidule

Mibadwo yam'mbuyo ya KRK Rokit imadziwika mosiyana - ena amawakonda, ena samatero. Lingaliro lambiri ndikuti iwo ali "DJ" mwamphamvu ndi "electronic". Zinthu ndizosiyana ndi m'badwo wachinayi Rokit ndipo ndithudi ndi chitsanzo cha 5-inch. Mutha kuwona bwino lomwe kuti ntchito zambiri zapita potengera chikhalidwe chawo cha sonic kupita kumlingo wina. Rokits sanakula modzichepetsa.

Zaka zambiri zazaka zambiri komanso zamakono zamakono zathandiza kuti KRK ipange mankhwala omwe amatha kupikisana mosavuta ndi owunikira a Adam, JBL ndi Kali Audio omwe ali ndi mtengo wofanana komanso wogwira ntchito.

Ngati muli ndi mwayi, yesaninso mtundu wa XNUMX-inch ndi XNUMX-inch woofer wa zipinda zazikulu pang'ono komanso kuntchito komwe muyenera kusewera mokweza komanso mabasi ambiri.
