Indlela yokubhekana nemisindo engaphandle evela ezipikheni

⭐ ⭐ ⭐ ⭐ ⭐ Abashayeli abaningi bavame ukubhekana nombuzo wokuthi bangasusa kanjani ukuphazamiseka (ukushaya umlozi, umsindo ovela ezipikheni), okuvame ukwenzeka kuma-acoustics emoto.

Le nkinga ingenzeka kunoma iyiphi isistimu ye-stereo, kungakhathaliseki ukuthi idivayisi ingeyasiphi isigaba, kungakhathaliseki ukuthi i-Budget yaseShayina, isabelomali esimaphakathi noma i-premium. Ngakho-ke, sincoma ukuthi ufunde lesi sihloko ukuze uthole ukuhlaziywa okunembe kakhudlwana kwemithombo engaba khona yomsindo omubi nezindlela zokuwuqeda.

Imithetho yokufaka eyisisekelo:

• Umthetho wokuqala. Ukuze umsindo wemoto ucace ngangokunokwenzeka, kuyadingeka ukuthi uthenge amakhebuli kagesi ekhwalithi ephezulu kanye nezintambo zesipika / zokuxhuma. Ngezimali ezilinganiselwe, ukugxila okuyinhloko kufanele kube kuzixhumi zekhebula ezixhumanisayo. Ngesikhathi sokusebenza kwemoto, uhlelo lwayo lukagesi ngokungenakugwenywa ludala izinkambu ze-electromagnetic ezihlukene ngobuningi, amandla kanye nezici zemvamisa. Ziyimbangela eyinhloko yomsindo ongena ezihlangu ezingenziwanga kahle zezintambo ze-RCA.
• Umthetho wesibili. Izintambo ze-interconnect kufanele zibekwe ngendlela yokuthi zibekwe kude ngangokunokwenzeka kwezinye izakhi zezintambo zikagesi zemoto. Futhi akumele zibe seduze nezintambo zikagesi eziholela ohlelweni lomsindo. Qaphela ukuthi ukungena komsindo kuzoncishiswa uma ukuphambana kwezintambo zesipika namakhebuli kagesi kufakwe nge-engeli elungile.

• Umthetho wesithathu. Ungalokothi uthenge izintambo ze-RCA ezinkulu kakhulu. Ubude bufushane, mancane amathuba okuthi ukhiqize i-pickup kagesi.
• Umthetho wesine. Ukufakwa okuklanywe kahle kwesistimu yomsindo wemoto kunikeza ukusekela kwazo zonke izici zesistimu endaweni eyodwa kuphela. Uma kungenjalo, uma izingxenye zisekelwe ezindaweni ezikhethwe ngokungahleliwe, lokho okubizwa ngokuthi "ama-ground loops", okuyimbangela eyinhloko. wokuphazamiseka lapho udlala umculo.

Ngemininingwane eyengeziwe mayelana nendlela yokuxhuma kahle i-amplifier, sihlole "lapha".

Amaluphu aphansi kanye nokucatshangelwa kokufakwa

Umthetho wesine ongenhla uthi esinye sezizathu ezenza kube nomsindo ongaphandle ezipikheni wukuba khona kwama "ground loops". Ukuba khona kwazo ezindaweni eziningana kubangela ukukhiqizwa kwama-voltage ahlukene ezingxenyeni ezithile zomzimba wemoto. Lokhu kuholela ekubukeni komsindo owengeziwe.

Umzimba wemoto, empeleni, uyinqwaba yensimbi, esetshenziswa "njengenhlabathi" yamasekhethi kagesi. Ukumelana kwawo nogesi kuncane, kodwa kukhona. Ayinawo umthelela ekusebenzeni kwemishini kagesi yezokuthutha ngokwayo, engakwazi ukusho ngesistimu yomsindo. Njengoba kukhona ama-voltages amandla ahlukene phakathi kwamaphuzu omzimba, ama-microcurrents aphakama, lapho ukugcwaliswa kwesistimu yesipika kuzwela kakhulu.

Ukuvimbela ukuba khona komsindo womsindo, kufanele usebenzise imithetho elandelayo:

• Uhlelo lwesisekelo lwenziwa ukuze zonke izingxenye ze "mass" zihlangane zibe iphuzu elilodwa. Isixazululo esihle kakhulu ukusebenzisa itheminali enegethivu yebhethri noma iphoyinti emzimbeni lapho itheminali eyinegethivu yendawo kagesi isekelwe khona. Lapho ukhetha i-wiring, kufanele kugcizelelwe ezintanjeni zekhwalithi ephezulu eziboshiwe, ukukhiqizwa kwazo okusebenzisa ithusi eline-deoxygenated. Indawo yokuxhumana kwekhebula nomzimba kufanele ihlanzwe kupende, ukungcola nokugqwala. Kunconywa ukunqamula ikhebula nge-crimping noma i-soldering ithiphu elikhethekile ngendlela yendandatho yobubanzi obufanele. Lapho udala izintambo zomhlabathi kanye namandla, thenga izixhumi ezifakwe ngegolide namatheminali;

• Izingxenye zensimbi zesistimu yomsindo akumele zihlangane nomzimba wemoto noma yikuphi. Uma kungenjalo, lapho ufaka ama-acoustics ngezandla zakho, umnikazi wemoto uzovusa ukubukeka kwe-loop yomhlabathi, nayo yonke imiphumela elandelayo;

• Uma zonke izintambo sezixhunywe kumsakazo namapheya amabili ezipikha, hlola ukusebenza kwawo. Vula isistimu ye-stereo futhi uhlole ngokuthi i-antenna inqanyuliwe. Ngokufanelekile, akufanele kube khona umsindo;
• Okulandelayo, udinga ukunqamula umhlabathi we-stereo emzimbeni. Uma konke kwenziwa ngendlela efanele, umsindo uzonyamalala, umsakazo ucime. Lokhu kuwubufakazi obuqondile bokuba khona kwendawo eyodwa yomhlabathi kanye nokungabikho kwezihibe. Akekho ozonikeza isiqinisekiso esingu-90% sokungabikho komsindo, noma kunjalo, uzozivikela ngamaphesenti angu-XNUMX.
  
  Kuyenzeka futhi ukuthi lapho ufaka isistimu yomsindo, akunakwenzeka ukugawula zonke izakhi endaweni eyodwa. Isixazululo senkinga ukukhethwa kwelinye iphuzu lokuxhuma ubuningi. Leli cala lisebenza kuphela lapho umehluko we-voltage phakathi kwesisekelo namaphoyinti aphansi angeziwe ungeqi ku-0.2V. Ngaphandle kwalokho, i-amplifier isekelwe ngemuva kwemoto, futhi i-equalizer, umsakazo kanye ne-crossover ku-partition yomzimba phakathi kwenjini nendawo yabagibeli.

Ngingathanda futhi ukuqaphela ukuthi isihlungi esihle ohlelweni siwukuba khona kwe-capacitor.

Indlela yokuqeda umsindo?

Sithole izimbangela zomsindo nezeluleko mayelana nokufakwa kahle kwezintambo nemishini. Cabangela futhi ukuthi yimaphi amaqhinga okufanele alandelwe ezimweni lapho, isibonelo, injini ithola umfutho, ibangele ukubukeka komsindo nokuphazamiseka?

Izixazululo zichazwe ngezansi:

• Nqamula iyunithi yekhanda kusistimu yomsindo. Uma kungekho msindo, yokugcina kufanele igxile endaweni evamile emzimbeni, esetshenziswa ezinye izingxenye ze-acoustic.

• Uma umsindo uqhubeka, futhi amaseli amiswe ezindaweni ezihlukene, thatha i-multimeter futhi uhlole i-voltage phakathi kwamaphoyinti aphansi azo zonke izingxenye kanye netheminali yebhethri ephansi. Uma uthola umehluko emiphumeleni, kufanele ulinganise i-voltage phakathi kwazo zonke izingxenye. Isixazululo esihle kuleli cala ukumisa zonke izingxenye endaweni eyodwa, noma uthole enye indawo lapho i-voltage phakathi kwezingxenye ingeke ihluke. Kumelwe kube nesilinganiso esincane se-voltage phakathi kwazo zonke izivalo ohlelweni. Ukufundwa kuhlolwa ngokulinganisa umehluko ku-voltage phakathi kwezihlangu (ama-braids) atholakala kumakhebuli e-RCA kunoma iyiphi inhlanganisela.
• Uma uthola umphumela omncane kakhulu emehlukweni kagesi ngesikhathi sokuhlolwa nge-multimeter, umsindo ovela ekuphazanyisweni ungavela ngenxa yezizathu eziningi: Esokuqala salezi singaba ukuba seduze kwezintambo ze-RCA ezintanjeni zamandla. Isizathu sesibili singase sibe indawo ehambisanayo neseduze yezintambo ze-acoustic kukhebula lamandla, noma ukunganaki i-engeli elungile yokuhlangana. Futhi qiniseka ukuthi ikesi le-amplifier lifakwe kahle. Ngaphezu kwalokho, i-antenna enesisekelo esingalungile ingakha izihibe futhi ibangele ukuphazamiseka. Isizathu sokugcina kungaba ukuthintana kwentambo ye-acoustic nomzimba wemoto.
  

  

  okutholakele

Esimeni lapho ukushaya ikhwela noma izinkinga ezengeziwe zibonakala ekusebenzeni kwezipikha, qiniseka ukuthi uhlola ukwakheka kwesipika emotweni yakho. Ukuhluleka ukulandela izincomo, ukusetshenziswa kwezinto ezisezingeni eliphansi noma ezilimele kuqinisekisiwe ukudala izinkinga ezinkulu ekusebenzeni kwesistimu ye-stereo.

Senze umzamo omkhulu ekwakheni lesi sihloko, sizama ukusibhala ngolimi olulula noluqondakalayo. Kodwa kukuwe ukuthi sikwenzile noma cha. Uma usenemibuzo, dala isihloko "kuforamu", thina nomphakathi wethu onobungane sizoxoxa ngayo yonke imininingwane futhi sithole impendulo engcono kakhulu kuyo.
