Okuqukethwe

Indlela 1 - Ukusethwa mathupha
Indlela yesi-2 - Sebenzisa umtshina Wokuhlanekezela
Indlela yesi-3 - Sebenzisa i-oscilloscope

Ukusetha i-amplifier eneziteshi ezi-4 kungaba nzima ngandlela-thile. Nazi izindlela ezintathu ezingaxazulula yonke into.

Ukusetha kahle i-amplifier eneziteshi ezi-4 kunezinzuzo eziningi. Ikhwalithi yomsindo enhle, impilo ende yesipika kanye nokuqedwa kokuhlanekezela ezinye zazo. Kodwa kwabaqalayo, ukusetha i-amplifier kungase kungabonakali ngenxa yobunzima benqubo. Ngakho-ke, ngizokufundisa izindlela ezintathu ezihlukene zokusetha i-amplifier eneziteshi ezingu-4 ngaphandle kokulimaza isistimu yomsindo wemoto yakho.

Ngokuvamile, ukusetha i-amplifier yeziteshi ezi-4, landela lezi zindlela ezintathu.

Funda i-walkthrough ehlukene ngezansi ukuze uthole imininingwane eyengeziwe.

Indlela 1 - Ukusethwa mathupha

Inqubo yokushuna mathupha ingase ibe inketho engcono kakhulu uma ufuna ukusetha okusheshayo. Kule nqubo, udinga kuphela i-screwdriver ye-flathead. Futhi kufanele ukwazi ukubona ukuhlanekezela ngokulalela nje.

Isinyathelo 1 Vala inzuzo, izihlungi neminye imiphumela.

Okokuqala, lungisa inzuzo ye-amplifier ibe ncane. Futhi yenza okufanayo ngezihlungi zokudlula eziphansi neziphezulu. Uma usebenzisa imithelela ekhethekile efana ne-bass boost noma i-treble boost, ivale.

Qiniseka ukuthi ukhubaza ukulungiselelwa okungenhla kuyunithi yekhanda futhi. Gcina ivolumu yeyunithi yekhanda ikuziro.

Isinyathelo sesi-2 - Yehlisa futhi wehlise ivolumu yeyunithi yekhanda lakho

Bese ukhuphula kancane ivolumu yeyunithi yekhanda bese uqala ukudlala ingoma ejwayelekile. Phakamisa ivolumu uze uzwe ukuhlanekezela. Bese wehlisa ivolumu phansi ezingeni elilodwa noma amabili kuze kube yilapho ukuhlanekezela kuqediwe.

Isinyathelo sesi-3 - Khulisa futhi unciphise inzuzo ku-amplifier

Manje thatha i-screwdriver ye-flathead bese uthola inkinobho yokuzuza ku-amp. Ngomusa jikisa ifindo lokuzuza ngokwewashi uze uzwe ukuhlanekezela. Uma uzwa ukuhlanekezela, vula ifindo ngokuphikisana newashi uze ukhiphe ukuhlanekezela.

Bese ukhumbula: Ingoma kufanele idlale kahle ezinyathelweni 3 no-4.

Isinyathelo sesi-4. Vala i-bass boost futhi ulungise izihlungi.

Bese uphendulela i-bass boost knob ibe nguziro. Ukusebenza nge-bass boost kungaba yinkinga. Ngakho-ke hlala kude ne-bass boost.

Bese usetha amafrikhwensi okuhlunga aphansi naphezulu oyifunayo. Lawa mafrikhwensi angahluka kuye ngama-subwoofers nama-tweeter asetshenzisiwe.

Nokho, ukusetha isihlungi sokudlula okuphansi sibe ngu-70-80 Hz kanye nesihlungi sokudlula okuphezulu sibe ngu-2000 Hz kunengqondo (uhlobo lomthetho wesithupha).

Isinyathelo sesi-5 - Phinda

Phinda izinyathelo 2 no-3 uze ufinyelele izinga levolumu okungenani elingu-80%. Ungase udinge ukuphinda inqubo izikhathi ezi-2 noma ezi-3.

Isikhulisi sesiteshi sakho esi-4 manje sesimiswe ngendlela efanele.

kubalulekile: Nakuba inqubo yokushuna ngesandla ilula, abanye bangase babe nenkinga yokuthola ukuhlanekezela. Uma kunjalo, sebenzisa noma iyiphi kulezi zindlela ezimbili ezingezansi.

Indlela yesi-2 - Sebenzisa umtshina Wokuhlanekezela

Umtshina wokuhlanekezela uyithuluzi elihle lokushuna i-amplifier eneziteshi ezine. Lapha ungafunda ukuthi ungayisebenzisa kanjani.

Izinto Ozozidinga

Umtshina wokuhlanekezela
I-screwdriver eflethi

Isinyathelo 1 Vala inzuzo, isihlungi neminye imiphumela.

Okokuqala, cisha zonke izilungiselelo, njengasendleleni 1.

Isinyathelo sesi-2 - Xhuma izinzwa

I-Distortion detector iza nezinzwa ezimbili. Zixhume kokuphumayo kwesipika se-amplifier.

Isinyathelo sesi-3 - Lungisa Ivolumu Yeyunithi Yenhloko

Bese ukhuphula ivolumu yeyunithi yekhanda. Futhi ngesikhathi esifanayo, hlola ama-LED womshini wokuhlanekezela. Okubomvu okuphezulu okokuhlanekezela. Ngakho, lapho idivayisi ithola noma yikuphi ukuhlanekezela, ilambu elibomvu lizokhanya.

Kuleli qophelo, yeka ukukhulisa ivolumu futhi wehlise ivolumu kuze kucishwe ilambu elibomvu.

Isinyathelo sesi-4 - Lungisa Inzuzo

Landela inqubo efanayo yokukhulisa isikhulisi njengasesinyathelweni sesi-3 (ukwandisa futhi unciphise inzuzo ngokuya ngokuhlanekezela). Sebenzisa i-screwdriver ukuze ulungise ukuhlanganiswa kwe-amplification.

Isinyathelo sesi-5 - Setha izihlungi

Setha izihlungi zokudlula eziphansi neziphezulu kumafrikhwensi alungile. Bese uvala i-bass boost.

Isinyathelo sesi-6 - Phinda

Phinda izinyathelo 3 no-4 uze ufike ku-80% wevolumu ngaphandle kokuhlanekezela.

Indlela yesi-3 - Sebenzisa i-oscilloscope

Ukusebenzisa i-oscilloscope kungenye indlela yokushuna i-amplifier eneziteshi ezine. Kodwa le nqubo iyinkimbinkimbi.

Izinto Ozozidinga

i-oscilloscope
I-smartphone endala
Ikhebula le-Aux-in yefoni
Amathoni amaningana okuhlola
I-screwdriver eflethi

Isinyathelo 1 Vala inzuzo, isihlungi neminye imiphumela.

Okokuqala, vala inzuzo, isihlungi, neminye imiphumela ekhethekile yeamplifier. Yenza okufanayo ngeyunithi yekhanda. Setha futhi ivolumu yeyunithi yekhanda ibe uziro.

Isinyathelo sesi-2 - Khubaza zonke izipikha

Bese unqamula zonke izipikha ku-amplifier. Phakathi nale nqubo yokusetha, ungalimaza ngephutha izipikha zakho. Ngakho-ke, zigcine zikhubazekile.

Isinyathelo sesi-3 - Xhuma i-smartphone yakho

Okulandelayo, xhuma i-smartphone yakho kokokufaka okuyisizayo kweyunithi yekhanda. Sebenzisa intambo ye-Aux-In efanelekile kulokhu. Bese ubuyisela ithoni yokuhlola. Kule nqubo, ngikhetha ithoni yokuhlola engu-1000 Hz.

Qaphela: Ungakhohlwa ukuvula iyunithi yekhanda kuleli phuzu.

Isinyathelo sesi-4 - Setha i-oscilloscope

I-oscilloscope iklanyelwe ukubonisa igrafu yesignali kagesi. Lapha ungabheka igrafu ye-voltage. Kodwa kulokhu, okokuqala udinga ukusetha kahle i-oscilloscope.

I-oscilloscope ifana kakhulu ne-multimeter yedijithali. Kufanele kube nama-probes amabili; Okubomvu nokumnyama. Xhuma intambo ebomvu embobeni ye-VΩ kanye nomthofu omnyama embobeni ye-COM. Bese uvula ukudayela kuzilungiselelo zamandla kagesi we-AC.

Sicela uqaphele: Uma kudingekile, lungisa izihlungi zokudlula okuphansi neziphezulu ngaphambi kokuqala isinyathelo sesi-5. Bese uvala i-bass boost.

Isinyathelo sesi-5 Xhuma inzwa kokuphumayo kwesipika.

Manje xhuma ama-oscilloscope probe kokuphumayo kwesipika.

Kule amplifier eneziteshi ezi-4, iziteshi ezimbili zinikezelwe kuzipikha ezimbili zangaphambili. Kanti ezinye ezimbili ezezipikha zangemuva. Njengoba ubona, ngixhume ama-probe esiteshini esisodwa esingaphambili.

Ama-oscilloscope amaningi anemodi yokuzenzakalelayo nezinombolo zokubonisa (i-voltage, yamanje, nokumelana). Kodwa udinga imodi yegrafu. Ngakho, landela lezi zinyathelo.

Bamba inkinobho ethi R imizuzwana emi-2 noma emi-3 (ngaphansi kwenkinobho F1).

Lungisa ukuzwela kwegrafu ngenkinobho ethi F1.

Isinyathelo sesi-6 - Nyusa ivolumu

Ngemva kwalokho khuphula ivolumu yeyunithi yekhanda kuze kube yilapho ingaphezulu nangaphansi kwesignali isicaba (lesi signali yaziwa ngokuthi isignali eqoshiwe).

Bese wehlisa ivolumu uze uthole i-waveform ecacile.

Nansi indlela ongasusa ngayo ukuhlanekezela usebenzisa i-oscilloscope.

Isinyathelo sesi-7 - Lungisa Inzuzo

Manje usungakwazi ukulungisa ukuzuza kwe-amplifier. Ukwenza lokhu, beka izinzwa ezimbili esiteshini esingaphambili esifanayo njengasesinyathelweni sesi-6.

Thatha i-screwdriver ye-flathead bese uvula isilawuli se-amplifier sokuzuza ngokwewashi. Kufanele wenze lokhu kuze kube yilapho i-oscilloscope ikhombisa isignali eqoshiwe. Bese uphendulela inkomba ngokuphambene newashi uze uthole i-waveform ecacile.

Phinda izinyathelo 6 no-7 uma kunesidingo (zama ukuzuza okungenani ivolumu engu-80% ngaphandle kokuhlanekezela).

Isinyathelo sesi-8 - Misa amashaneli angemuva

Landela izinyathelo ezifanayo njengezinyathelo 5,6, 7, 4 no-XNUMX ukuze umise amashaneli angemuva. Hlola isiteshi esisodwa ngasinye ukuze uthole amashaneli angaphambili nangemuva. Isikhulisi sakho sesiteshi esingu-XNUMX manje sesimisiwe futhi silungele ukusetshenziswa.
