izihloko Izithuthi, ukudlula noma iyiphi enye, ikakhulukazi eduze iningi labantu besilisa wezwe enkulukazi. Abaningi bethu ukuchitha isikhathi esiningi kanye nemali, ngokuletha "umngane yensimbi 'yakhe kuze kufike komkhulu wabo kungenzeka ukuphelela. Lokhu kuyiqiniso ikakhulukazi uma kuziwa imoto umculo umsindo. Ngaphezu kwalokho, ngaso sonke isikhathi sifuna ukuzama ngandlela-thile ugcine ngokwenza okungenani ingxenye umsebenzi ngezandla zakhe. Ngaphezu kwalokho, bonke owake ukwenza okuthile okokuqala. Siphinde sinikhumbuze ukuthi kungcono namanje ukukala kasikhombisa phambi kokwenza okuthile. Le ndlela uzokusindisa isikhathi esiningi kanye nemali.

Namuhla sikhuluma kanjani ukuxhuma amplifier emotweni. Sikholelwa ukuthi lesi sihloko kuyoba ozithandayo.

Ake ucabange ukuthi unayo vele hhayi kuphela ukukhetha imodeli kwesokudla, kodwa futhi zangisiza ekwenzeni indawo ukufakwa emotweni yakho. Manje kufanele wenze wiring kuhle powering amplifier, bese ixhume ku-udluliseleke futhi prokinut ikhebula umsakazo ngokwayo. Nokho, ake sixoxe konke kabanzi.

amplifier sikagesi

Beginners owaqala nazo umsindo imoto zifikelwa umnyombo wire ukushuba, okuyinto asivamile ukubonwa ekuphileni kwansuku zonke (kahle, ngaphandle ukuthi bejwayele ukusebenzisa imishini Welding noma into efana lokho kanye emsebenzini wami - ke unayo le ndlela ngeke umangale).

Ngokuphambene nalokho okukholelwa yiningi, yokukhulisa umsindo uqede kusukela ugibelile ugesi imisinga ukubaluleka ehloniphekile. Ngakho, iyunithi emine isiteshi Watts isiteshi ngamunye 50 Uzodla cishe 17 A. Akukubi, akunjalo? Yiqiniso, ezifeza izidingo ezihlukahlukene liner kuyodingeka usebenzise ngocingo nge engxenyeni enkulu ngempela esiphambanweni. Ngakho ngaphambi kokuzama ukusebenzisa amplifier emotweni, vakashela ezitolo okukhethekile.

I version zakudala

Ake sihlole wiring classical. Kulokhu, wiring ninamathele ngqo ibhethri imoto. Akusiyo imfihlo ukuthi ezimweni eziningi ibhethri ngaphansi hood, kuyilapho amplifier itholakala ngaphakathi imoto. Ngakho, le ntambo omuhle egcina cishe lonke ingaphakathi imoto. Yingakho kubalulekile ukuvikela wiring usebenzisa izinga okusezingeni eliphezulu Hambayo fuse, futhi kufanele ibekwe ubhekisise cm 30 kusukela ibhethri.

Ngakho ngaphambi kokuzama ukusebenzisa amplifier emotweni, ngisho vakashela esitolo electronics kanye ukuthenga fuse evamile.

Nasi ukwahlukanisa

Futhi, ungakhohlwa ngaphezu kwalokho ngci ikhebula, njengoba kusuka 17 A trifled nge. Ikakhulukazi kufanele bavikele ngokucophelela endaweni phakathi gumbi injini ingaphakathi, njengoba ikhebula kukhona ngokuvamile frays. Njengomthetho, kukhona gasket iraba, kodwa zikhona ezehlukile. Uma kunjalo, akuvimbeli ukusetshenziswa imikhono plastic eyenziwe ngepulasitiki eqinile futhi angabacwasi obukhulu. Abantu Abadala Abavuthiwe indlela lolu daba, ngoba ivumela ukubanjwa wagcoba ikhebula angenalutho emzimbeni metal ngokusobala aliwona umzamo!

endlwaneni eyakhiwe futhi kudingeka donsa bentambo, ukugwema ukuchayeka yayo ingxenye ezihambayo. Kube khona izindaba lapho abantu prokidyval skids ngaphansi kwesihlalo ikhebula. Kwamanye kungase kubangele nemiphumela ungakwazi yini ukubhala imigomo ngokwabo. Ngakho indlela ukuxhuma amplifier emotweni?

Ukukhetha ikhebula

Ungakhohlwa Wegolide: emalungeni ezincane, ukuphepha ngenhla! Ubuningi izintambo nge ezahlukene cross-section igcwele okusezingeni eliphezulu amandla ukulahlekelwa, futhi kusukela iphuzu Ngenxa ukuphepha komlilo akubukeki ngendlela engcono.

Ngaphezu kwalokho, lokususa wire kwesigaba ungakwazi ukukwenza kufanele kulingane ukuthi ikhebula omuhle. Inethiwekhi yamanje ingenye, ukubaluleka kwalo njalo. Uma izintambo kuzodingeka izigaba ezahlukene, bayoba overheat, okuyinto futhi igcwele umlilo emotweni.

Nalapha futhi, ukuthi izintambo mncane - ukumelana okusezingeni eliphezulu. Akunakusetshenziswa musa skimp on izintambo ukuthi balekela ibhethri yokukhulisa umsindo, njengoba sishilo umsinga amandla eyehlayo on kubo.

Ngiphethe physics kanye mathematics

Okokuqala, hlola ukuthi yini lemali wamanje kudliwe amplifier esetshenziswa nguwe. Ukuze wenze lokhu, ukubheka fuse (noma fuses). Ake sithi amplifier yakho kungaba kwakuthiwa ukumelana 100 A. ngokushesha umbeka kangcono esiqwini. Ukuze imoto ejwayelekile kungcono ukuthatha ngamamitha okungenani ezinhlanu.

I = 100; L = 5 m.

Ngisho nokusetshenziswa esiphezulu wamanje, yokwehla kwamandla ekupheleni plus we wire akumele leqe 0.5 V Ukukhumbula aphansi ukumelana esikoleni ukubala ifomula, bese enze ukucabanga elula:

Yandise R = U / mina = 0, 5 V / 100 A = 0, 005 ohms.

Ngakho, ukumelana ikhebula kumele singeqi 0, 005 ohms. Njengoba sihlela ukulala zisebenzisa eziningi kuneziyisihlanu amamitha, kubalulekile ukubala ukungawi ingxenye imitha:

R m = R Tot / L = 0, 005/5 = 0 futhi 001 ohms.

Njengoba ubona, sidinga wire nge ukumelana komugqa ohms akazidluli 0 no 001 / m. Futhi manje ungathatha ikhathalogi yanoma yimuphi umakhi, bese ukhetha into efanelekayo.

Ixhuma ikhebula

Ngemva umzila wena ngocingo kule gumbi, ungaxhuma ke ukuphela omuhle amplifier. Minus ikhebula ixhunywe ngqo emzimbeni, futhi lokhu kubalulekile ukusebenzisa ikhophi efanayo cross-section ukuthi we plus. Akunakusetshenziswa aziphendukeli ngosizo nezikulufi! Namathisela imishudo kuphela, iphuzu uxhumano zigezwe kusukela esiphezulu izinga iminonjana upende nezinye izinto.

wire ibhethri Positive Kumele uxhumeke ukuphela + 12V, kanye negative - ukuze GND (phansi - phansi, GND). Ngaphambi kokuxhuma amplifier umsakazo, ukuthola oxhumene kude, ngoba yakhelwe bahlanganyele bentambo ukuthi nje uhamba. Yilapho futhi kukhona labo kunazo 12V, kodwa ngenxa nomsakazo ongasebenza umsebenzi amplifier. Ngokuvamile lokhu ikhebula siluhlaza (noma oluhlaza okwesibhakabhaka kanye umugqa omhlophe). Kungaba kuhle ukufaka uhlelo njengoba capacitor.

Donsa ikhebula zisebenze noma zingasebenzi emsakazweni

Siyaqhubeka ngenela lo mbuzo: "? Indlela ukuxhuma amplifier umsakazo" Manje sidinga ukusebenzisa ikhebuli okuyothi ngalo isignali ngizoya kusukela umdlali amplifier. Njengomthetho, yena livela okukhipha umugqa (Line Out), isiqu esithi "izinsimbi" ku iphaneli labaqaphi elingemuva.

Sicela uqaphele ukuthi onobuhle umsakazo ezahlukene kanye ezivela abakhiqizi ezahlukene ingase ibe inombolo ehlukile komugqa okukhiphayo. Ngokuvamile, kukhona imibhangqwana emithathu, kodwa abadlali professional ngezinye izikhathi ezingaphezu. Lokhu kuveza lokhu okulandelayo: Front, engemuva futhi Sub, eyenzelwe uxhumano phambi, azungeze izinhlelo umsindo, kanye subwoofer. Iyiphi udinga - incike onjani amplifier emotweni oyithengile.

It uxhuma zonke izintambo oluchazayo, esibonakala by Ukuhlolwa ukugqanyiswa. Eqinisweni, kukhethwa wire ngempela badonsekela isihloko isihloko ehlukile, ngakho umphumela ngokwethu komunye umkhandlu wethu. Akunakusetshenziswa musa skimp on ke, bathenge imikhiqizo kuphela eyaziwa kanye nabaphakeli omethembayo.

Ngaphambi kokuxhuma amplifier emotweni yakho, ungabi engadingekile futhi ufunde imiyalelo yokusebenza. Lokhu kuzokusiza uyogwema izinkinga eziningi.

Xhuma ikhebula amplifier ukulawula

kakade Sithe kubalulekile ukubeka izintambo ukulawula by amplifier. Phela, kungcono ukwenza, emakhiyubhi oluchazayo wire. Ikakhulukazi ukuthi kukhona ikhebula ekhethekile le njongo e onobuhle eziningi. Omunye ekupheleni kuxhunywe ku-amplifier (waphinda ukukukhumbuza ukuthi ababethi okwesibhakabhaka noma okwesibhakabhaka nomhlophe), kanye nezinye - umsakazo. Ithiphu: ukuthenga amandla emotweni, qiniseka ukuthenga zonke izintambo kanye naye, ngoba kungcono uthintane ngazo umdayisi.

Akubalulekile ukuthenga engxenyeni enkulu ikhebula, njengoba kudlule imisinga encane kakhulu ngalo.

amanothi Kubaluleke kakhulu

inothi ezibaluleke kakhulu: noma kunjalo, ungalilahli umzila oluchazayo wire eduze amakhebuli kagesi! Ngokwesibonelo, uma wiring amandla nethinta ngokusebenzisa gumbi, izintambo ukulawula ngizodabula ngakwesokunxele, ngangokunokwenzeka emandleni !!!

Ngaphezu kwalokho, ungakwazi yokwelula nabo ngaphansi mata salon, njengoba kulokhu, okungenzeka esiphezulu hhayi "catch" umsindo. Uma alinge ubuwula emhlabeni, kuvuleke izintambo ngemuva kwenye, bese lapho injini uzosilalela cod, nihewule nezinye umsindo izikhulumi. Ayikho enye indlela kodwa ngokuphelele yenza wonke umsebenzi kuleli cala ngeke. Ngakho indlela ukuxhuma amplifier emotweni - bazikhandla isikhathi eside oyisicefe ke akudingekile ukuba asheshise.

Ezimweni ezimbi kakhulu, izintambo futhi benza kufanele donsa ophahleni, ukuzifihla ngaphansi Upholstery. Lokhu kuyiqiniso ikakhulukazi ngokuphathelene izimoto cutting edge ukuthi basuke ngokoqobo "eyayigcwele" tinhlobo letehlukene electronics. Kulokhu, isiphazamiso ukuze kubalulekile ngezinye izikhathi ukusebenzisa Ukuhlolwa ekhethekile.

Umehluko yokuxhuma izinhlobo ezahlukene yokukhulisa umsindo

Uma ubeka amplifier ezimbili isiteshi, uzodinga efanayo oluchazayo ikhebula. Uma isikwele - pair of kabili wire noma emine ekhethekile.

Futhi indlela ukuxhuma amplifier umsakazo, uma ine- kuphela pair of umugqa okukhiphayo, futhi amplifier - Four? Kulokhu, ungakwazi ukusiza ezikhethekile Y-adaptha (idabula). Onobuqili Chinese wadala idivaysi enikeza Okokufaka pair of okukhiphayo ngamunye. Ngakho, kusukela pair stereo esinawo ezimbili nje. Ihlangene, akukho lutho. Yiqiniso, ukwenza kanjalo ne umsindo eliphakeme intengo isigaba akudingekile, ngoba izinga umsindo ngesikhathi esifanayo encishisiwe kakhulu.

Kukhona enye indlela esingathola. Zonke onobuhle ejwayelekile yokukhulisa umsindo yesimanje (Audison, isibonelo) anemisila umsebenzi wokusabalalisa sangaphakathi okokufaka ngokulinganisa. Kafushane, kulesi simo, noma isiphi isandiso awudingi.

Uma okukhipha umugqa kusukela isidlali sakho ungangiboni, kungenziwa exhunywe ngqo izikhulumi (isignali okusezingeni eliphezulu). Cishe wonke amadivayisi evamile Okwamanje unama ezikhumulweni abafanele (Hi ezingeni okufakwayo). Ukuze uxhume usebenzisa ezivamile isikhulumi izintambo, futhi kungaba ngcono ukuba uhlanganise izigxobo.

Xhuma amplifier owodwa isiteshi (eyaziwa ngokuthi yi- ibha candy)

Ngo onomzali isiteshi yokukhulisa umsindo ube umsebenzi eyodwa kuphela - ukuxhuma kwi-subwoofer. Sinenkosi amandla ehlonipheke kakhulu, kodwa futhi sibe nekhono emsebenzini ngaphansi ephansi impedance umthwalo. Kuyini, endleleni, na? Ngo ezivamile yezimoto impedance acoustic of ohms 4 kuphela, kanye nazo zonke ezinye imishini Ukucaciswa aphansi kakhulu (3 ohms, 2 ohms, 1 Ohm). Lokhu kubizwa ngokuthi umthwalo ephansi impedance. Zonke lezi yokukhulisa umsindo kukhona D-class.

Namuhla, bonke baye esakhelwe LPF Elihehayo losike zonke amaza ngenhla lezo enizibekela yona njengomkhaya esiphezulu ukuze subwoofer. Isifunda exhunywe ihlazo ilula. Subwoofers axhunyiwe parallel noma uchungechunge, noma isikhulumi esisodwa kuphela is agibele amahhashi. Ngo parallel, ungaxhuma ngisho engaphezu kwemibili woofers ngesikhathi esisodwa, kodwa kubalulekile ukwazi ukuthi yini wonke amamodeli we subwoofers angabhekana ngayo ukumelana kakhulu anda.

Sinikeza ezivamile futhi elula obandayo isikimu. isignali Linear kusukela rekhoda iya amplifier, wafingqa futhi iyakhula. Wiring umdwebo control kanye ne-transmission izintambo okutholakala imiyalelo evela nomkhiqizi wakho.

Indlela ukuxhuma amplifier ezimbili siteshi?

Futhi manje siyazi ukuthi ukuxhuma amplifier umsakazo, uma imodeli ezimbili-siteshi. Amadivayisi zaloluhlobo zinzima kwabaningi pad ukuqaliswa ezweni umsindo wemoto. Isizathu ukuthi izindleko hhayi kuphela ongaphakeme, kodwa futhi lula. Lezi yokukhulisa umsindo avame ukusetshenziswa ukuxhuma kwi-Izikhulumi phambi noma subwoofer. Ake sixoxe ngayinye yalezi zindlela.

Ixhuma izikhulumi phambi

Uma uhlela ukusebenzisa Iyunithi "jika" ngaphambili noma izipikha ezingemuva, ixhume imodi stereo. Ngakho, indlela ukuxhuma msindo ezimbili siteshi?

Isignali inikezwa ezingeni eliphansi noma eliphezulu. Kuyinto efiselekayo ukuxhuma ongaphakeme-pass lemifanekiso (HPF), okuyinto kubalulekile uma obandayo lesi sifunda. Kulokhu, umthwalo amplifier ngayinye angase up 2 ohms. Ngakho, ukuhlola ichannel yinye ngayinye kungenziwa hung kwenye ohlelweni isikhulumi 4 ohms.

Ukuxhumanisa subwoofer

zedivayisi ejwayelekile kakhulu izincwadi zabo kulokho okubizwa ngokuthi "ibhuloho 'inketho. Ngaphambi indlela ukuxhuma subwoofer ukuba amplifier, qiniseka ukuthi "freshness" zedivayisi: cishe wonke amamodeli entsha ngokuphelele zisebenzisa kule modi. Ngakho, imiyalo yabo kukhona imidwebo enemininingwane ebonakalisa kuphi futhi kanjani ukuxhuma izintambo emihle nemibi. Kulokhu, amandla sihlanganiswe, nomsindo eyatholakala futhi elihlale juicier.

Ngaphezu kwalokho, iphaneli ezingemuva siqukethe izithonjana zohlelo ezibonisa nezixhumi ngoba le ntambo kagesi, phansi, futhi lelo gumbi ngu izintambo ukuze izikhulumi. Kulula ukuqonda. Nakhu ukuthi ukuxhuma subwoofer ukuze amplifier. Akukho nzima kakhulu, akunjalo?

Abanye onobuhle abe inkinobho ekhethekile, ngawo ungadlulisa amasu mono imodi. Kubaluleke kakhulu: uma usebenzisa ibhuloho imodi, khumbula ukuthi kuleli cala, cishe zonke "Amps", ngaphandle ezingavamile, azisebenzi ngaphansi umthwalo esingaphansi 4 ohms! Ngaphambi ukuxhuma subwoofer ukuba amplifier, zinyanga kufanele zifakwe isihlungi LPF. Uma kungenjalo, zonke amaza ngenhla 50-100 Hz ngizokuya subwoofer, futhi incithakalo esingenathemba umsindo. Kungenzeka ngeke uthande ngisho abantu abangekho kulungile nge indlebe umculo.

Iziteshi amane!

Futhi indlela ukuxhuma msindo 4-siteshi? Ngokuvamile, futhi kulokhu kukhona lutho nzima. Positive ibhethri ikhebula silingo, elandela iziyalezo ngenhla (wire ukuthatha izinga mkhulu futhi kangcono ngangokunokwenzeka).

Line okukhiphayo emsakazweni (RCA - Tulips) kufanele kube zozine. Uma kunjalo 2, ukuthenga idabula, okuyinto thina kakade okukhulunywe ngaye ngenhla. Lineyniki enamathiselwe umdlali futhi amplifier. Uma uya ukuxhuma amplifier umsakazo ifektri, qiniseka unqamule ibhethri, njengoba lokhu kungase ashise fuse.

Okulandelayo, ikhebula lokulawula (akude) kwelula phakathi tape umsindo futhi Amps. Njengoba sishilo kakade, kuba mncane kakhulu futhi yayidinga eliphezulu Ukuhlolwa. Khona-ke exhunywe izikhulumi, noma izilungiselelo.

Indlela ukuxhuma olulodwa-siteshi amandla amplifier?

Lolu hlobo imishini - uxhumano langempela kwelinye icala single- kanye ezimbili-isiteshi onobuhle. Ngakho, kungenzeka ukuxhuma subwoofers eminingi, bese Imiphumela ezisele (ezimakwe nge imifanekiso okuhambisanayo) "hang" ngaphambili nezipikha labaqaphi elingemuva.

Indlela ukukhweza yokukhulisa umsindo eziningana?

Indlela ukuxhuma yokukhulisa umsindo ezimbili? Uma uhlela ukufaka emotweni amabhlogo eziningana walolu hlobo, kunezindlela ezimbili tekwenta loku. Okokuqala - nje ukufinyelela omunye ikhebula obukhulu kusukela ibhethri, bese ngikhipha idabula kuya yokukhulisa umsindo zamanje. Nakani! Uma bentambo lungaphezu 40 amasentimitha, futhi sibe aphansi (kuqhathaniswa ngekhebula main) ubukhulu, kubaluleke kakhulu ukuba abavikele esebenzisa fuses.

Inombolo yokukhetha ezimbili. Dweba ibhethri njengezintambo eziningi njengoba unama-amplifi efakiwe. Naphezu kokuyinkimbinkimbi kwezobuchwepheshe kwesisombululo esinjalo, ngokusemandleni akuyona into esabekayo. Iqiniso liwukuthi izintambo ezimbalwa ezincane kakhulu zingahle ziphonswe kalula kunomunye owodwa. Futhi okubaluleke kakhulu: kulesi simo, udinga ukucabangela kuphela ukuthi ungaxhuma kanjani ama-amplifiers angu-2. Futhi awukwazi ukukhathazeka ngamafuses nhlobo.

Donsela izintambo ohlelweni lwesipikha

Ake sikhulume ngezici zokuxhuma ama-amplifiers nezikhulumi. Njengoba sesishilo kakade ngezikhathi eziningana, kubalulekile ukusebenzisa izintambo ezikhethekile ngalokhu. Bangakwazi ukweluleka, ngaphandle kokwesaba ukuphazamiseka kwamanye ama-electronic emotweni. Kodwa kwi-crossover acoustic "pickups" yokubamba iqhaza, ngakho-ke ikhebula kumele lifakwe kunoma yikuphi emithonjeni yezingqinamba ezingenzeka.

Kunenkinga eyodwa kuphela. Kungenxa yokudonsa ikhebula emnyango. Ngakho ungaxhuma kanjani i-amplifier kuzikhulumi? Ezimweni eziningi, abakhiqizi abakhohlwa ngabathengi, beshiya izixhumi ezikhethekile zokubeka iziteshi zekhebula noma ukufaka imikhono yerabha. Kodwa ngokuvamile lezi zipho ezivela embonini yemoto azikwazi ukulinda, ngakho-ke kufanele zitshale izimbobo ezengeziwe.

Ungakhohlwa ukukhipha terminals ebhethri ngaphambi kokwenza umsebenzi!

Amanye amathiphu

Uma ufunda ngokucophelela lesi sihloko, cishe uke wabona okushiwo yi-fuses. Yimaphi amamodeli asetshenziswa kakhulu ukuvikela uhlelo?

Iyunithi yekhanda ingavikeleka ekushiseni ngomshini ojwayelekile wokuphepha ojwayelekile.
