Uninzi lweemvumi ziyakuthanda ukurekhoda imidlalo yabo kunye nokusebenza kwiindawo ezinamasixhobo esinesandi, ngakumbi abo badlala izixhobo zomculo kunye nesandi esibuthathaka nesifutshane. Oku kubandakanya zonke izinto ezinqabileyo zeleyibhile, ngakumbi iigitari zombane, izixhobo zayo ngaphandle kwe-Amplifier ayinakuthethwa, musa ukuvelisa nasiphi na isandi. Kwindawo enye kukho zombini iimvumi zezinye iiprofayili zokudlala nge-elektroniki okanye ngemibane yomculo.
Isandi esinamandla esingapheliyo siqwalaselwa kwizixhobo ezincinci zobhedu (i-FOLTE, ukuphakamisa i-proontoca, sweatshi kunye neminye imibhobho). Kwiiholo ezinkulu zekonsathi, i-Bayan kunye ne-incume iya kuviwa kakhulu. Ewe kunjalo, kukho nombane, kungekuphela nje ngenxa yeziphumo ezininzi, kodwa nako ukukhuphisana nezinye izixhobo nakwiinkundla ezinjalo, njengemidlalo kunye namasimi emidlalo kunye namasimi asezantsi.
Qwalasela kweli nqaku imixholo ye-Lamp yeLamp Gitar Amplifiers ekhaya kunye nofakelo lwabo ngokwabo.
Iipeksi
Kwigitari, ngakumbi abo benza iikonsathi okanye badlala igita yombane, kubaluleke kakhulu ukukhetha i-Amplifier elungileyo, ekhupha izandi eziphezulu zekagasi. Nangona kunjalo, ayizizo zonke iimvumi ze-novice zinethuba lokufumana izixhobo ezixabisa kakhulu iifemu ezaziwayo ezibandakanyeke kumbungu onjalo.
Kudala yaziwa ukuba Esona sizathu sendalo sinokuvelisa i-Lamp Gitar Amplifiers (amaBanzi). Esi sizathu asiyi nakuphi na ukuthelekisa kunye ne-Amplifishi ye-chips kunye nokuhambisa - isibane kuphela sinokunika izandi ezicocekileyo, iyunifomu kunye nezantya ezinomtsalane. Kodwa iindleko ze-lempssional ye-lempssional ye-Amplisional Amplifie eveliswe zizikhundla zehlabathi ngumyalelo wobukhulu obuphezulu kunayo nayiphi na indibaniselwano kunye ne-semicondyus.
Kuyinyani, i-Lamp Amplisheers ineempawu ezithile ezingekhoyo kwizixhobo ze-analog. Oku kubandakanya:
- ubuninzi kunye nobunzima bemveliso egqityiweyo;
- Ukuthembeka okwaneleyo kwezibane xa kuthelekiswa nokuzihambisa;
- Ukufudumeza okuqinileyo kweenxalenye, ezinokukhokelela ekonakaleni kwekhonkco lombane kunye nokusilela kwezinye izinto;
- Ukunqongophala kwabasebenzi kwizibane ezifanelekileyo ngenxa yokusasazeka kwezixhobo ze-elektroniki kwaye ngokuthe ngcembe ukongamela ukuveliswa kwezixhobo zeaudiyo zeaudiyo zeaudio eziphelileyo kunye nezixhobo.
Kodwa Obu bunzima abunqabi iimvumi ngendlela yokufumana isandi esiphezulu seegitare zabo. Ke ngoko, zihlala zizama ukukhetha i-Ampifier yasekhaya ilungele neNdlu, emva koko bayiqokelela ngezandla zabo, ngokungathandabuzekiyo kuya kubiza imali ebiza kakhulu kunezixhobo zefektri.
Ukufumana ezona ndlela zilungileyo, kuyanyanzeleka ukuba kuhlalutywe kakuhle, thethane ukuba kunokwenzeka kwiingcali, bhala uluhlu lweenxalenye zezinto ezifanelekileyo ze-Amplifier kunye nesiseko sayo (i-chassis) Iinxalenye zibekwe kwaye zenziwe ngekhonkco eliphakathi kwazo.
Izixhobo kunye nezixhobo
Uqeqesho lwasekhaya kumdlalo wegita okanye irekhodi lemisebenzi yomntu ilungele kakhulu igitare elula kwi-Lamps kunye nezinye iinkcukacha ezibonelela ngemveliso yesandi yokukhupha ngaphakathi 1.5-3.0 W. Kuya kwanela ukuba benze ngempumelelo indlela yomdlalo, yenza irekhodi elingaphezulu lokudlala elilinganayo okanye iingoma eziphantsi kwe-acoustic kwaye, kunjalo, ukuba zenze imithambo yabamelwane abakufuphi. Ke ngoko, ungakhetha ukhetho lwe-Amplimier eyenza le nkcukacha zesekethe yombane:
- I-Lamp-triode 6N1P (okanye i-analogues yayo: i-6n3p, i-6N2P, i-6N23P), imfuneko kwi-Cascade yesikimu sonke;
- I-6p14p yesibane (i-perter), ithatha inxaxheba kwisiphelo (ukuphuma) seschema;
- Imveliso yemveliso ye-Audformer Tutz-1-1, yenzelwe umthwalo wangoku ngaphakathi kwe-8 ye-OHM kunye namandla e-3 W (inokutshintshwa i-analogue ye-twz-1-9, ebalwe kuphela kumthwalo ongaphezulu kwe-4 I-OHMS, okanye oochwephesha be-TCE engafunekiyo, kodwa abayi kukwazi ukucinezela ukugqwetha izandi);
- I-560 kω umphenduli wokungena;
- Umxhasi kwi-CAMODE yesibane se-lamp-trio ngu-0.5 w, kwi-anom-0.5-1.0 w;
- I-Capacitor kwi-ShuntS ngesikithi se-cathode-tristor rio ngesikhongozeli esiphezulu kunye ne-voltage malunga ne-10 v;
- I-condenser kumgca wonxibelelwano phakathi kwee-cascades kufuneka zibe ngamafutha ukusuka kwi-300 v, kunye nomgca wokuyeka okufanayo kulayini ofanayo kungafikelela kwi-100 ye-COM ukuya kwi-1000 kω;
- Umxhasi we-Mathode wesibane sePester kufuneka ube namandla ngakumbi kune-infuthe kwi-intanethi
- USomlomo yi-8 Ohms.
Kwiqonga, ungasebenzisa iphepha elinobunzima njengento ebonakalayo, uyiluse kwifom yecompact, ukuphinda ikhumbule ibhokisi ngaphandle kwecala elingezantsi, okanye uthenge imveliso esezantsi. Abanye abasebenzisi basebenzisa ityala lakudala lekhompyuter kwiqonga phantsi koMphezulu, betshona inxenye yesiciko malunga nobungakanani obufunayo.
Ukongeza, izixhobo ziya kufuna iingcingo zokunyusa isiphaluka sombane, kunye neentambo kunye neplagi yesixhobo kwinethiwekhi kunye nentambo yokuqhagamshela isixhobo kwi-Amplifier.
Ukusuka kwizixhobo ezinamasa, izixhobo zomthengisi kunye nomthengisi kufuneka zilungiswe, isinyithi kunye ne-weapper, impompo kunye ne-gluws kunye neekreyithi kunye nabaphawu lokumakisha.
Iskim semveliso
Iskimu esicetywayo sokwenza i-Amputha yeGuitar ephantsi yeGuitar yinkqubo yenqanaba le-cascade ye-Cascade enokungena. Umsebenzi wayo ulele ngokwahlula-hlulwa komqondiso kwi-Inlet kwi-Amplimier ibe ngamaza amabini anesiqingatha samaza, aphikisana nezigaba. Iskimu se-INTERNETER I-INTERMER ilula kwaye inika iziphumo ezilungileyo ukuphucula umsebenzi we-Amplifier, kodwa ayisoloko isebenza, ngakumbi kwizixhobo ezisemgangathweni eziphezulu, njengoko isandi sigqwesile. Kodwa kwi-Amplifiers enamanzi aphantsi, esi sixhobo siza kuluncedo.
Xa ufaka isikimu sombane se-Amplifier, iingcali zicebisa ngomyalelo wokungabikho kwinqanaba lokuqala (ukungena), kodwa kususela komhla wesibini.
Okokuqala, qokelela i-Peto yenxalenye yesikimu, isithethi, isibane kwaye uqhagamshele, kwaye uqhagamshele inxalenye yesekethe kwinethiwekhi yombane. Ukuba yonke into ihamba kakuhle, ke kwii-Dynamics onokuthi uve ukuqhekeza okanye imvelaphi xa isibane sichukunyiswe ngesandla. Emva kovavanyo olunjalo, unokuqhubeka nokusebenza. Ngaphandle koko, kuya kufuneka ujonge impazamo kwaye uyiphelise. Emva kokuqokelela inqanaba lokuqala, kuya kufuneka ujonge ukusebenza kweskimu. Ukwahlula-hlula kwamanyathelo kuya kumisela ukuba yeyiphi na indawo yesikimu kukungasebenzi kakuhle ukuba imeko engathandekiyo ivela kwindawo enamandla.
Ngamanye amaxesha iwela ngovavanyo ukuvelisa uhlengahlengiso lokugqibela lwe-Amplifier ukuze ifumane isandi esingcono sesandi sesixhobo somculo. Kule nto, kunokwenzeka ukutshintsha ezinye iinkcukacha kwi-analogies kunye nezinye iiparamitha (umthamo weeparamitha, amanye amandla okuqeqesha, njalo njalo). Kwenzeka ukuba izibane kufuneka zitshintshe kwinqanaba lokuseta isandi.
Ungayenza njani i-lamp gitar i-amplifier enezandla zakho, jonga kwividiyo engezantsi.
