Kuti asimbise kana kurekodha kurira kwakapfava kweiyo acoustic gitare, pamwe nekutevedzera vanonyarara gitare remagetsi pacharo, iwe unofanirwa kuvabatanidza kune gitare amplifier. Asi wekupedzisira unodiwa chimwe chakakosha chinongedzo chekuwana ruzha-rwemhando yepamusoro - iyo preamplifier, iri zvakare pream. Mune zvemazuva ano fekitori amplifiers, iyo prepamp yakatoiswa mune imwe imba yekugara nekusimbisa uye kubereka michina yemidziyo. Nekudaro, izvi hazvisi nyore nguva dzose. Nezveizvi uye zvimwe zvinhu zvegitare zvinofungidzirwa, pamwe nesarudzo yezvakanakisa zvavo ichakurukurwa mushure - mune chinyorwa.
Chii chiri uye nei uchidikanwa?
Kana tikataura nezve mabasa anopihwa prepar preamp, iwe unogona kunyora zvinotevera zvakatevera mabasa makuru:
- kugashira kwemasaini yemagetsi kubva kuchiridzwa;
- Kugadzirisa kwakagashirwa chiratidzo kuti uvandudze hunhu hwavo;
- Kusimbisa chiratidzo kune mutsara wedanho;
- Kuendesa masaini akagadziriswa kune simba amplifier block.
Kana zviri nyore kujekesa basa rePreampa, rinogadzirira chiratidzo chinouya kubva pane pickup pickups kana maikorofoni yekuenderera mberi nekuenderera mberi kune simba amplifier uye simba. Pasi pekuvandudzwa kwemhando yezvikwangwani, chokwadi chekuti iri muchirevo cherudzi rwunowana inzwi rakasiyana nemamwe, semuenzaniso kuti: "Kukanganisa" (Kukanganisa), Enhancer (Enhancer (Enhancer (Enhancer (BENACUC) uye vamwe. Iyo yakakwira-mhando preamp ndiyo hwaro hwekuita basa rakabudirira mune yeruzhinji uye kuwana ruzha rwemhando yepamusoro kana uchinyora. Pasina iyo, hazvigoneke kuita gitare mumamiriro ezvinhu apo hazvigoneke kutora gitare amplifier zvachose.
Uye mudziyo pachahwo kana Semiconductor Circuit ine hardware yakaiswa (marambi, vatengesi, vanobatira, vakabatana neimwe nzira inovimbisa kushanda kwayo kwePreampa). Iyo prep ndeye scripty yakabatana pakati pegitare uye iyo main amplifier, uye mutauri ari kumagumo - pane iyo yekubuda chiteshi chesimba. MuPreampe, iyo isina kusimba chiratidzo inouya kubva kuGitare pickups nekuda kwekuwedzera kweiyo voltage. Panguva imwecheteyo, iyo iripo inoshandurwa isingabvumirwe. Iyo yazvino inowedzera mune iyo main amplifier, uye voltage inowedzera zvakare.
Izvo zvinofanirwawo kucherechedzwa kuti Iyo yekutanga yakabatana nechiridzwa chemimhanzi pachayo, pasina simba rekushandisa, haripe ruzha rwekunze, saka zvakakodzera chete zvekurekodha, uye kwete kwenzvimbo yekongireti. Asi kukanganisa kwayo kwakakosha pane ruzha rwekutanga chokwadi chokwadi. Kazhinji, mharidzo dzakatoiswa munzvimbo yegitare, saka ichave yakakwana kutenga chimplifier (sarudzo yesimba rekushandisa pasina preampa ichabhadhara ruzha ruzha rwezwi).
Ongororo yemarudzi
Prelminary Amplifiers yeAcoustic uye Magetsi Gitars akakamurwa kuita marudzi maviri makuru: tube uye transistor. Isu tinovapa tsananguro pfupi.
- Rambi. Pakarepo tinogona kutaura kuti mwenje mwenje unokosheswa zvakanyanya, sezvo marambi ndiwo marekodhi echinhu ichi chinopa ruzha rwekudzika, kudziya, musical harikics. Izvo zvakare zvakataurwa kuti ruzha nekuda kwekushandurwa kwemarambi kwezviratidzo zvinova nemafuta, ndiko kuti, density uye mweya wekunzwa wakanyatsonzwa zvachose. Mukuwedzera, midziyo yemwenje ine kumanikidzwa kwechisikigo, inonakidza runyerekupe.
- Transistor. Mukupesana nemarambi analogues, aya preamplifiers anofungidzirwa kuti "pachena", kureva kuti, vanotarisana nemanzwi enhamo nemhedzisiro. Ivo vanoshanda vasina kupisa kusunungurwa, zveupfumi uye zvinyoro-nyoro. Nekudaro, zvishandiso zvakadaro zvinokanganisa uye zvisati zvichidikanwa, sevatengesi, kunyangwe ivo vachishanda nekuwedzera kukuru muchiratidzo, asi kukanganisa hakubvumirwe.
Kuwedzera kune "kuchena" transistist kana zvishandiso zvechiRamita zvekuwedzera kurira kwegitare, kuchine madhiri ekushambadzira, kusanganisira zvikamu uye matanho emarambi, uye transistor. Semuyenzaniso, Pane sarudzo dzekuti chikamu chekuisa chakaunganidzwa pane vatengesi, uye kubuditsa gadziriso marara (Summit Audio 2ba-221 pream). Mune ino kesi, chiratidzo chekuisa kubva pamapikicha kana maikorofoni inoitwa nekukurumidza, yakanatswa kubva pakuru nemwenje iri nani, uye nekubuda nekuda kwemarambi anozadzwa nemhedzisiro uye kupisa. Zvinozopedzisira wakunda mune zvese.
Asi nyanzvi dzinoona zano rebrid rakanyanyo. Ngatione kuti ndeupi maitiro ekusarudza iyo yakanakisa muenzaniso weiyo preamp yegitare kazhinji inotora basa rekushandira zvakanaka (viitarists ivo pachavo).
Nuanes dzevana
Kusarudza preamplifier yako gitare, muimbi wehunyanzvi anotamba nechiridzwa cheAcousic, chekutanga pane zvese zvinofunga nezve munhurume wezwi rake, izvo zvinoda kuti: kushamwaridzana kwekushandisa, kwakaringana . Mune ino kesi, anozoda kuziva kuti asarudze mhando yehybrid. Izvo zvichakwanisa kuchenesa uye kusimudzira chiratidzo chekuisa, chengetedza marefu epamusoro uye pendi ruzha pakubuda. Chisarudzo cheSpuristor chinogoneka kana gitare ichirera kumhanya uye yepamusoro frequency.
Kana iyo gitare ine ruzha rwunoteteza rusina kudzivirira kuwedzera zvinoreva uye density, sarudzo yakanakisa ichave iyo Lamp preamp. Zvinotenderana, neakanaka uye wepakati freedency zvichave zviri nani kutenga sarudzo yekufambisa kuitira kuti urege kukurira neyakawandisa mitezo yepamusoro, ichipinda mumaoko emhando yemhando yePreampa.
Zvekutanga, iwe unogona kukurudzira chero nzira yekutandarira kana iyo hybrid. Chero zvazvingaitika, ndezvekutarisirwa zvisina ruzivo neyekuhwina sarudzo: Uye mari yacho ichada zvishoma, uye ruzha runopa yakachena, ine matanda akanaka.
Asi gadiri rimwe nerimwe rine chiratidzo chayo ruremekedzo, saka nekuedza uye nekumanikidza kuongororwa kwebasa remuenzaniso weiyo gitar prept mune yakaiswa negitare yayo inofanirwa kuwana sarudzo yaunoda.
Zvekunyora zvinouraya kana mavheti, mhando yemhando yePreampa inofanira kunge isisarudzwi. Asi bvunza neunyanzvi haambokurumidzi.
