Nzira yekusarudza magetsi gitare amplifiers uye vatauri?

Ese magitare emagetsi anoendesa chiratidzo kune amplifiers. Mhedzisiro yekupedzisira inobva pavari. Iwe unofanirwa kuyeuka kuti kunyangwe iyo yakanakisa gitare yakabatana kune isina simba amplifier haizonzwika zvakanaka. Sezvo kunyanya kunofanira kubhadharwa pakusarudzwa kwe "choto" chakakodzera maererano nekusarudzwa kwechiridzwa.

Rambi, hybrid uye transistor

Tube amplifiers yakaita basa rakakosha munhoroondo yegitare remagetsi. Mazuva ano, machubhu anodiwa pakushanda kwechubhu amplifiers haabudiswe muhuwandu hukuru. Makumi emakore apfuura vaidiwa mumaindasitiri mazhinji, asi iye zvino vari kudiwa zvakanyanya mumusimboti chete muindasitiri yemimhanzi uye mamwe maapplication echiuto, izvo zvakakonzera kuwedzera kwemitengo yavo. Kune rumwe rutivi, kuvandudzwa kwemagetsi epamusoro kwakakonzera kuderera kwemitengo ye transistors uye kuwedzera kwehutano hwavo. Vazhinji vagadziri vakatogadzira nzira dzekutevedzera ruzha rwemachubhu nema transistors kune zvakanaka. Zvakadaro, amplifiers anowanzo kusarudzwa nenyanzvi ndeaya anobva pamachubhu. Imwe mhinduro yaive yekugadzira mahybrid amplifiers. Aya madhizaini ane chubhu preamplifier uye transistor simba amplifier, inovimbisa sonic maitiro akafanana nechubhu amplifiers, asi nekushandiswa kwema transistors mumagetsi amplifier, ayo akachipa kupfuura chubhu maseketi. Izvi zvinoguma nemutengo wakaderera pane chubhu amplifiers, asiwo ruzha haruna se "chubhu" semuchubhu chaiyo "oven".

Dzidziso mukuita

Iko hakuna chikonzero chekuvanza kuti chubhu amplifiers ichiri kupa iri nani ruzha. Nekudaro, ivo vane mashoma ekushandisa akashata ayo asingashande kune transistor amplifiers. Chekutanga pane zvese, kana vavakidzani vedu kana vatinogara navo vasiri mafani ekutamba zvine ruzha, hazvikurudzirwe kutenga mahombe echubhu amplifiers. Machubhu anoda "kubatidzwa" kune imwe nhanho kuti aite kuti aite zvakanaka. Yakapfava = ruzha rwakaipa, ruzha = ruzha rwakanaka. Transistor amplifiers inonzwika seyakanaka pavhoriyamu yakaderera seyakakwira vhoriyamu. Izvi zvinogona kudzivirirwa nekutenga yakaderera-simba (semuenzaniso 5W) chubhu amplifier. Sezvineiwo, izvi zvine chekuitawo nedikidiki dzegudzanzwi. Kuipa kweiyi mhinduro ndeyekuti amplifier yakadaro ichakwanisa kutamba chinyararire uye ichava neruzha rwakanaka, asi inogona kushaya simba remakonzati ane ruzha. Uye zvakare, iyo yakanakisa ruzha inowanikwa ne12 "vatauri. A more power transistor amplifier (eg 100 W) ine 12 “loudspeaker inogona kunzwika zvirinani pane diki chubhu amplifier (eg 5 W) ine gudzanzwi diki (eg 6”) kunyangwe iri pasi. Hazvisi izvo zviri pachena, nekuti iwe unogona kugara uchikudza iyo amplifier nemakrofoni. Zvinofanira kucherechedzwa, zvisinei, kuti pane chikonzero nei magudzanzwi akanakisa anoshanda neakasimba-state uye chubhu amplifiers anenge agara aine gumi nemaviri "matauri (kazhinji 12 x 1", 12 x 2 "kana 12 x 4").

Yechipiri yakakosha nyaya ndeye mwenje inotsiva pachayo. Iko hakuna machubhu mu transistor amplifier, saka haafanire kutsiviwa, nepo muchubhu amplifier machubhu anopera. Icho chiitiko chemusikirwo chose. Dzinofanirwa kuchinjwa nguva nenguva, uye izvi zvinofanirwa kudhura. Nekudaro, pane chinhu chimwe chinoshandura zviyero kuenda kumachubhu amplifiers. Kuwedzera kukanganiswa kwechubhu ine yekunze cube. Rondedzero yevanoridza magitare vari kuishandisa yakarebesa kupfuura rondedzero yevasiri vashandisi. Iko kukanganisa mu "tube" kunofadza kunyange harmonics, uye iyo iri mukusarudza - isinganzwisisiki harmonics. Izvi zvinoguma neruzha rwakanaka, runopindirana rwakakanganiswa. Iwe unogona, hongu, kutamba mutambo wekusimudzira yakasimba-state amplifier, asi zvinosuruvarisa inofarira zvisinganzwisisike harmonics pamwe nekuwedzeredza mucube, saka hazvizonzwika zvakafanana.

Combo i stack

Iyo combo inosanganisa amplifier uye gudzanzwi mune imwe imba. Stack izita remubatanidzwa amplifier (munyaya iyi inonzi musoro) uye gudzanzwi mudzimba dzakasiyana. Chakanakira checombo mhinduro ndechekuti inonyanya kufambisa. Kazhinji kazhinji, zvisinei, zvirinani sonic mhedzisiro inowanikwa nekuda kweiyo stack mhinduro. Chekutanga, unogona kusarudza zviri nyore masipika kana kunyange akawanda masipika sezvaunoda (mumakombi zvinokwanisika kutsiva iyo yakavakirwa-mukati sipika, asi zvakanyanya kuoma, asi kazhinji pane zvakare sarudzo yekuwedzera yakaparadzana gudzanzwi kune. iyo combo). Mumachubhu combos, marambi ari mudzimba dzakafanana nemagudzanzwi anoratidzirwa kune yakakwira ruzha, izvo zvisingavabatsire, asi zvisingakonzerese mhedzisiro yakaipa. Machubhu ari mumusoro wechubhu haaonekwe kune dzvinyiriro yeruzha kubva pagudzanzwi. Single-box transistors ine gudzanzwi zvakare inotarirwa nekumanikidzwa kwekurira, asi kwete zvakanyanya semachubhu.

Nzira yekusarudza sei column?

Magudzanzwi akazaruka kumashure achanzwika zvakanyanya uye achisununguka, nepo akavharwa achanzwika akasimba uye akatarisisa. Iyo yakakura iyo gudzanzwi, zviri nani iyo inogona kubata yakaderera frequencies, uye idiki iyo yakakwirira. Iyo chiyero ndeye 12 ", asi iwe unogona zvakare kuedza gumi", ipapo ruzha runenge rusina kudzika, rwakanyanya kusiyanisa mune yakakwirira frequencies uye zvishoma kudzvanywa. Iwe zvakare unofanirwa kutarisa iyo impedance yemusoro. Kana tikasarudza gudzanzwi rimwe chete, iyo impedance yegudzanzwi uye musoro unofanirwa kuenzana (zvimwe zvisiri izvo zvinogona kushandiswa, asi kazhinji ndiyo yakachengeteka uye yakachengeteka nzira).

Chinhu chidiki chakanyanya kuoma kubatanidza vatauri vaviri kana vanopfuura (pano ini ndicharatidza nzira yakachengeteka, izvo zvisingareve kuti ndiyo chete nzira inogoneka). Ngatitii amplifier ndeye 8 ohms. Kubatanidza makoramu maviri e8 ohm kwakafanana nekubatanidza imwe 4 ohm column. Naizvozvo, maviri 8 - ohm makoramu anoenderana neimwe 16 - ohm amplifier inofanira kubatanidzwa kune 8 ohm amplifier. Iyi nzira inoshanda kana iyo yekubatanidza ichienderana, uye parallel kubatana kunoitika muhuwandu hwakawanda hwezviitiko. Nekudaro, kana kubatana kuri kutevedzana, semuenzaniso kune 8-ohm amplifier, iyo yakaenzana yekubatanidza imwe 8-ohm column ichave ichibatanidza maviri 4-ohm makoramu. Kana iri simba rezvitauriri uye amplifier, zvinogona kushandiswa zvakaenzana kune mumwe nemumwe. Iwe unogona zvakare kushandisa gudzanzwi rine mawatts akawanda kupfuura amplifier, asi yeuka kuti isu kazhinji tichaedza disassemble amplifier kuti tiishandise zvakanyanya sezvinobvira. Iyi haisi pfungwa yakanaka nekuda kwengozi yekuikuvadza, ingozvichenjerera nezvazvo.

Ehezve, isu tinogona zvakare kusanganisa yakakwirira simba amplifier nemutauri wepasi. Mumamiriro ezvinhu aya, haugone kupfuudza nekubvisa "chitofu", asi panguva ino nekuda kwevatauri. Inofanirawo kuyeukwa kuti, somuenzaniso, amplifier ine simba re 50 W inogona, kutaura nekutaura, "kubudisa" 50 W. "Ichaendesa" 50 W kune rimwe gudzanzwi, semuenzaniso 100-watt, uye kune maviri 100. -watt magudzanzwi, kwete 50 W kune imwe neimwe yadzo.

Rangarira! Kana usina chokwadi nezvemagetsi, bvunza nyanzvi.

Features

Imwe neimwe amplifier ine 1, 2 kana kutopfuura chiteshi. Iyo chiteshi mune 1-channel amplifier inenge inogara yakachena, saka chero kukanganisa kunogoneka kunofanirwa kubva kwakavakirwa chete kune ekunze cubes. 2-channel chiteshi, sekutonga, inopa chiteshi chakachena uye nzira yekukanganisa, yatinogona kushandisa tega kana kuisimudzira. Kune zvakare amplifiers ane chakachena chiteshi uye mashoma kukanganisa kana kunyange mashoma akachena uye mashoma kukanganisa. Iyo "yakawanda, iri nani" mutemo haushande pano. Kana iyo amplifier, kunze kwegwara rakachena, ine, semuenzaniso, 1 chete nzira yekukanganisa, asi yakanaka, uye imwe, kunze kweiyo yakachena, ine 3 yekukanganisa nzira, asi yemhando yakaipisisa, zviri nani sarudza yekutanga amplifier. Anenge ese amplifiers anopawo yakaenzana. Izvo zvakakodzera kutarisa kana kuenzana kwakajairika kune ese chiteshi, kana kana chiteshi chine EQ yakaparadzana.

Mazhinji amplifiers anewo akavakirwa-mukati modulation uye spatial mhedzisiro, kunyangwe kuvepo kwavo kusingakanganise kunaka kweiyo toni yekutanga inogadzirwa neakapihwa amplifier. Nekudaro, zvakafanira kutarisa kana paine modulation uye spatial mhedzisiro yatove mubhodhi. Mazhinji amps ane reverb. Zvakakodzera kutarisa kuti iri digital here kana kuti chirimo. Digital reverb inoburitsa chirevo chemazuva ano, uye chirevo chechirimo chinoburitsa chirevo chechinyakare. Iyo FX loop inobatsira kubatanidza akawanda marudzi emhedzisiro (sekunonoka, korasi). Kana isipo, inogona kugara yakavharirwa pakati peamp negitare, asi inogona kunzwika yakaipa mune mamwe mamiriro. Migumisiro yakadai sewah - wah, kukanganisa uye compressor hainamati muchiuno, inogara ichiiswa pakati pegitare uye amplifier. Iwe unogona zvakare kutarisa kuti ndezvipi zvinobuda (semuhedhifoni, musanganiswa) kana zvinopinza (semuenzaniso zveCD uye MP3 player) iyo amplifier inopa.
