Abaculi abaningi bayakujabulela ukurekhoda imidlalo yabo kanye nokwenza imisebenzi ekhonsathini ngemishini yokomisa imisindo, ikakhulukazi labo abadlala izinsimbi zomculo ezinomsindo obuthakathaka futhi omfushane. Lokhu kufaka phakathi konke okuhlukile kwelebula, ikakhulukazi amagigili kagesi, amathuluzi awo ngaphandle kwe-amplifier akunakushiwo, ungaveli noma yimuphi umsindo. Esikhundleni esifanayo kukhona bobabili abaculi bakwamanye amaphrofayili adlala izinsimbi zomculo kagesi noma zikagesi.
Umsindo oqinile oqinile ubonwa kwizinsimbi ezincane zethusi (umtshingo, ukuphakamisa i-harmonica, sweatshi namanye amapayipi). Ehholo elikhulu lamakhonsathi, ngisho neBayan ne-acconion bazwakala buthakathaka impela. Kuyiqiniso, kukhona nogesi, olwakhelwe hhayi kuphela imiphumela eminingi, kepha futhi ukuncintisana namanye amathuluzi ngisho nakuzo zonke izingosi zethamethi, njengezinkundla eziphansi.
Cabanga ngalesi sihloko izici zesibani se-guitar amplifiers ekhaya nokufakwa kwazo ngokwazo.
Ubuhlakani
Kuma-guitarists, ikakhulukazi labo abenza amakhonsathi noma abadlala isiginci sikagesi, kubaluleke kakhulu ukukhetha i-amplifier enhle, ekhipha imisindo esezingeni eliphezulu yesigingci. Kodwa-ke, akubona bonke abaculi be-novice abanethuba lokuthola imishini ebizayo yezinkampani ezaziwayo ezibandakanyekile kumagazini wobunjiniyela obunjalo bomsindo.
Kudala kwaziwa ukuthi Umsindo wemvelo kakhulu ungakhiqiza ama-wamp Guitar amplifiers (ama-couria). Lo msindo awuyi kunoma yikuphi ukuqhathanisa nama-amplifiers anamuhla kuma-chips kanye nama-transiors - Isibani kuphela esinikeza umlaleli ohlanzekile ngokuphelele, umfaniswano kanye nobuhle nge-bass noma i-melodic ethe xaxa. Kepha izindleko ze-amplifiers ezingenamsebenzi ezikhiqizwa yimikhiqizo yomhlaba ekhiqizwa ngumkhiqizo womhlaba ingumyalo wobukhulu obuphakeme kunanoma iyiphi inhlanganisela ne-semiconductors.
Kuliqiniso, ama-amplifiers obani anokunye okubi okungekhona kumadivayisi we-analog. Lokhu kufaka phakathi:
- ubuningi nobuningi bomkhiqizo ophelile;
- Ukuthembeka okunganele kwamalambu kuqhathaniswa nama-transistors;
- Ukushisa okuqinile kwezingxenye, ezingaholela ekulimaleni kweketanga kagesi nokwehluleka kwezinye izinto;
- Ukuntuleka kwezabasebenzi kwamalambu adingekayo ngenxa yokusabalala okugcwele kwamadivayisi we-elekthronikhi bese kufakwa kancane kancane ukukhiqizwa kwezingxenye zemishini yokusebenza nemishini eyedlule.
kepha Ubunzima obungayeki abaculi endleleni yokuthola umsindo wekhwalithi ephezulu yezigingci zabo. Ngakho-ke, ngokuvamile amaGuitarists azama ukuthatha i-amplifier eyenziwe ekhaya efanelekile endlini, bese ayiqoqa ngezandla zazo, okungabangenzi ukuthi zibize kakhulu kushibhile kunedivayisi yefektri.
Ukuthola inketho engcono kakhulu kuwe, kuyadingeka ukukuhlaziya kahle, ukubonisana uma kungenzeka ngochwepheshe, bhala uhlu lwezingxenye ezidingekayo zohlelo lukagesi lwe-amplifier kanye nesisekelo salo (chassis), lapho kusethi yonke wezingxenye zitholakala futhi zenziwa ngeketanga elikhuphukayo phakathi kwalo.
Amathuluzi nezinto zokwakha
Ngokuqeqeshwa kwasekhaya komdlalo we-Guitar noma irekhodi lemisebenzi yomuntu ngamunye lilungele i-amplifier elula yesigingci emalambu kanye neminye imininingwane enikezela okukhishwayo komsindo okungu-1.5-3.0 W. Kuzokwanela ukufeza ngempumelelo inqubo yomdlalo, yenza irekhodi eliphakeme kakhulu lokudlala noma izingoma ezingaphansi kokuhambisana kwakho esigungwini se-acoustic futhi, kunjalo, senze kancane ezinhlungwini zomakhelwane abaseduze. Ngakho-ke, ungakhetha inketho ye-amplifier eyenzelwe wena ngemininingwane enjalo yomjikelezo kagesi:
- I-Lamp-Triode 6N1P (noma izifaniso zayo: I-6N3P, i-6N2P, 6N23P), okudingekayo) i-Cascade yohlelo lonke;
- I-6p14P Lamp (PENTER), ukubamba iqhaza ekugcineni (okukhipha) i-Chema Cascade;
- Umphumela wokukhipha i-Transformer TWZ-1-1, eyenzelwe umthwalo wamanje ngaphakathi kwe-8 OHM namandla ka-3 W (ungathathelwa indawo nge-analogue ye-TWZ-1-9, okubalwa kuphela emthanjeni ongabi ngaphezu kwe-4 Ama-ohms, noma akhethekile akhethekile we-tce tcerformers, kepha ngeke akwazi ukucindezela ngokufanelekile ukuhlukunyezwa kwemisindo);
- I-560 Kω Shweler Resistor;
- I-Resistor eCathode of the Lamp-Trio ingu-0.5 W, ku-anode - 0.5-1.. W;
- capacitor ku-shunt nge-cathode sussession lamp-trio ngesitsha esiphezulu kanye nogesi olungaba ngu-10 v;
- Umncintiswano olayini wezokuxhumana phakathi kwamakhasathi kufanele abe nguVoltage kusuka kuma-300 v, futhi ukumelana okuguqukayo emgqeni ofanayo kungaba ngamapharamitha kusuka ku-100 com kuze kufike ku-1000 kω;
- I-Resistor eCathode yesibani sePenter kumele ibe namandla kakhulu kunaseLamp (Order 2 w), ngokumelana kwama-120 ohms, kanye ne-shunt condenser inesikhundla esiphansi ngokuqhathaniswa ne-shunt emjikelezweni ovuthayo;
- Isikhulumi singu-8 ohms.
Ukuze uthole ipulatifomu, ungafaka ishidi elibanzi le-Duralumin njengezinto ezibonakalayo, ulikhiphe kwifomu elihlangene, ukukhumbuza ibhokisi ngaphandle kohlangothi olungezansi, noma uthenge umkhiqizo ophelile. Abanye abasebenzisi basebenzisa icala lekhompyutha elidala lepulatifomu ngaphansi kwe-amplifting, ecwila ingxenye yesembozo ngosayizi oyifunayo.
Ngaphezu kwalokho, izinto zokwakha zizodinga izintambo zokubeka umjikelezo kagesi we-amplifier, kanye nezintambo kanye ne-plug yedivayisi ukuze inethiwekhi 220 V. Masinyane kudingeka ukuthi unakekele i-Amplifier.
Ukusuka kumathuluzi akhuphukayo, imishini ye-soler ne-soled kufanele ilungiselelwe, insimbi enesethi yokushayela insimbi, izinto zokwelapha, izikulufo kanye nama-screwdrivers, ama-glue, imithetho nezimpawu zokumaka.
Uhlelo lokukhiqiza
Uhlelo oluhlongozwayo lokwenziwa kwe-amplifier ye-Guitar ephansi luwuhlelo lwesigaba ezimbili lapho i-Converter Converter CASCADE engangena khona. Umsebenzi wayo ulele ekuhlukanisweni kwesiginali endaweni yokungena kwi-amplifier ibe ngamagagasi amabili, aphambene ngezigaba. Uhlelo lweSigaba Inverter lulula futhi lunikeza imiphumela emihle ukuthuthukisa umsebenzi we-amplifier, kepha ungasebenzi ngaso sonke isikhathi, ikakhulukazi imishini esezingeni eliphakeme, njengoba umsindo uhlanekezelwe kakhulu. Kepha kuma-amplifiers anamandla anamandla, le divayisi nakanjani izosebenziseka.
Lapho ufaka uhlelo lukagesi lwe-amplifier, ochwepheshe beluleka i-oda lomsebenzi hhayi kusuka esigabeni sokuqala (ukungena), kepha kusukela ngosuku lwesibili.
Okokuqala, ukuqoqa ingxenye ye-Pento yohlelo onomguquli, isipikha, isibani kanye ne-shunt, bese uxhuma i-transformer nengxenye ye-cathode yesetheku ku-punduct kunethiwekhi kagesi. Uma konke kuhamba kahle, khona-ke kuma-Dynamics ungezwa ukuqhekeka noma ingemuva lapho isibani sithintwa ngesandla. Ngemuva kwesivivinyo esinjalo, ungaqhubeka nokusebenza. Ngaphandle kwalokho, uzodinga ukubheka iphutha futhi uqede. Ngemuva kokuqoqa isigaba sokuqala, kufanele futhi uhlole ukusebenza kweSikimu. Ukuhlukaniswa okunjalo kokufaka ezinyaweni kuzonquma ukuthi iyiphi ingxenye yeSikimu okuwukusebenza kahle uma ingemuva elingathandeki livela kumandla ashukumisayo.
Kwesinye isikhathi iwela izivivinyo ukukhiqiza ukulungiswa kokugcina kwe-amplifier ukuthola umsindo ongcono wokukhipha wensimbi yomculo. Ukuze uthole lokhu, kungenzeka ukuthi ushintshe imininingwane ethile kuma-analOgues namanye amapharamitha (umthamo wama-capacitors, elinye amandla okumela, nokunye). Kwenzeka ukuthi amalambu aguquke esiteji sokubeka umsindo.
