Indlela yokuxhuma i-amplifier yemoto ngezandla zakho
Okuqukethwe
⭐ ⭐ ⭐ ⭐ ⭐ Uma uthi nhlá, ukuxhuma i-amplifier emotweni kungase kubonakale kuyinkimbinkimbi. Beka amandla, xhuma umsakazo nezipikha. Kodwa uma unomyalo omuhle wesinyathelo ngesinyathelo ezandleni zakho, ngeke kube nezinkinga, futhi akunandaba ukuthi kusetshenziswa i-amplifier ye-4 noma 2-channel. Ungasheshi ukuxhumana nesevisi yemoto, ukufakwa kochwepheshe kuzobiza, ngakho-ke ukuze ulondoloze imali, kufanele uzame ukuzitholela uxhumano ngokwakho, lesi sihloko sizokusiza.
Ukuze i-amplifier isebenze, udinga:
- Mnike ukudla okuhle;
- Nikeza isignali evela emsakazweni. Ungafunda imininingwane eminingi ngokuhlola umdwebo wokuxhumana womsakazo;
- Xhuma izipikha noma i-subwoofer.
Ukuze uthole ulwazi olwengeziwe mayelana nendlela yokuxhuma i-amplifier, bheka ngezansi.
Ukudla okunomsoco kuyisihluthulelo sempumelelo
Inqubo yokuxhuma i-amplifier iqala ngezintambo zamandla. Izintambo ziyisici esibaluleke kakhulu sesistimu yomsindo wemoto, inquma ivolumu nekhwalithi yomsindo. Ama-amplifiers adinga ukunikezwa kwamandla okuzinzile, ngoba ngaphandle kwalokho ngeke kube namandla anele, ngenxa yalokhu, umsindo uzohlanekezelwa. Ukuze uqonde ukuthi kungani udinga ukunaka izinga lezintambo nokuthi liwuthinta kanjani umsindo okhiqizwe yisipikha, udinga ukwazi ukuthi iyini isignali yomculo.
Abanye basikisela ukuthi imele i-sine, nokho, i-singal yomculo ibonakala ngomehluko omkhulu phakathi kwenani elivamile neliphakeme. Uma izikhulumi ze-acoustics yemoto, ukuqhuma okubukhali kwesignali akukona okuyisisekelo, khona-ke esimweni se-amplifier, isimo sihluke ngokuphelele. Uma isignali ngisho nomzuzwana (noma ngisho ne-millisecond) idlula amandla avumelekile, khona-ke lezi "ezingavamile" zizozwakala ngisho nalabo abangakwazi ukuziqhayisa ngendlebe enhle yomculo.
Uma uxhumano lwe-amplifier yemoto lwenziwe ngendlela efanele, khona-ke isignali izohamba ngezintambo ngendlela engaguquki. Umsebenzi owenziwe ngokunganaki noma usayizi wentambo okhethwe ngokungalungile uzobangela umsindo ukuthi uboshwe kakhulu, ube mahhadlahhadla futhi ube bushelelezi. Kwezinye izimo, ukushaywa umoya kungase kuzwakale ngokucacile.
Indlela yokukhetha usayizi wezintambo?
Ucingo luyinsimbi evame kakhulu enezinga elithile lokumelana. Ukuqina kocingo, kunciphisa ukumelana nocingo. Ukuze ugweme ukuhlanekezela komsindo ngesikhathi sokuguquguquka okuqinile kwe-voltage (isibonelo, ngesikhathi sokudlala i-bass enamandla), kuyadingeka ukufaka ucingo lwegeji elungile.
Kumele kuqashelwe ukuthi ingxenye yesiphambano sekhebula elihle akufanele libe likhulu kunelibi (ubude abunandaba).
I-amplifier ibhekwa njengethuluzi elinamandla kagesi. Ukuze usebenze ngempumelelo, ukubekwa phansi kwekhwalithi ephezulu kuyadingeka ukuze ukwazi ukuthola amandla adingekayo ebhethri.
Ukuze ukhethe i-cross-section efanele yezintambo, udinga ukwenza izibalo ezithile. Ukuze uqalise, bheka imiyalo ye-amplifier (noma ngokuqondile ebhokisini elivela kumkhiqizi, uma kungekho mibhalo, sebenzisa i-intanethi) futhi uthole inani lamandla alinganiselwe (RMS) lapho. Amandla alinganiselwe amandla esignali esikhulisi esingawaletha isikhathi eside esiteshini esisodwa esingu-4 ohms.
Uma sicabangela ama-amplifiers aneziteshi ezine, ngokuvamile anamandla angama-watts angu-40 kuya kwangu-150 isiteshi ngasinye. Ake sithi i-amplifier oyithengile ikhipha amandla angu-80 watts. Njengomphumela wemisebenzi elula yezibalo, sithola ukuthi amandla aphelele we-amplifier angama-watts angu-320. Labo. sikubale kanjani? kulula kakhulu ukuphindaphinda amandla alinganiselwe ngenani lamashaneli. Uma sine-amplifier eneziteshi ezimbili enamandla alinganiselwe (i-RMS) angama-watts angu-60, isamba sizoba ngama-watts angu-120.
Ngemva kokubala amandla, kuyafiseleka futhi ukunquma ubude bocingo kusuka kubhethri kuya ku-amplifier yakho futhi ungasebenzisa ngokuphepha ithebula ukuze ukhethe ingxenye yocingo oyifunayo. Isetshenziswa kanjani itafula? Ngakwesobunxele, amandla e-amplifier akho abonisiwe, ngakwesokudla, khetha ubude bocingo, khuphuka futhi uthole ukuthi yisiphi isigaba esidingayo.
Ithebula libonisa izingxenye zezintambo zethusi, khumbula ukuthi izintambo eziningi ezithengiswayo zenziwe nge-aluminium eboshwe ngethusi, lezi zintambo azihlali isikhathi eside futhi zinokuphikiswa okwengeziwe, sincoma ukusebenzisa izintambo zethusi.
Ukukhetha i-fuse
Ukuze uvikele ukuxhumeka kwe-amplifier yemoto, kuyadingeka ukuvikela ukunikezwa kwamandla kusuka kubhethri kuya ku-amplifier usebenzisa i-fuse. Amafuse kufanele abekwe eduze kwebhethri ngangokunokwenzeka. Kubalulekile ukuhlukanisa phakathi kwe-fuse evikela idivayisi ngokwayo (kungakhathaliseki ukuthi izoba i-amplifier noma i-tape rekhoda yomsakazo), kanye ne-fuse efakwe ocingweni lwamandla.
Lesi sakamuva siyadingeka ukuze kuvikelwe ikhebula ngokwalo, njengoba kugeleza umsinga omkhulu kulo.
Qinisekisa ukufanisa izilinganiso ze-fuse, njengokungathi isilinganiso se-wiring fuse siphezulu kakhulu, ucingo lungashisa ngenxa yesifunda esifushane. Uma inani, ngokuphambene nalokho, lincane, khona-ke i-fuse ngesikhathi semithwalo ephakeme ingashisa kalula futhi ngeke kube khona enye indlela yokuphuma ngaphandle kokuthenga entsha. Ithebula elingezansi libonisa usayizi wentambo kanye nesilinganiso se-fuse esidingekayo.
Sixhuma izintambo zokuxhuma nokulawula (REM)
Ukuze ubeke ikhebula, udinga ukuthola umugqa wokuphuma emsakazweni. Okuphumayo komugqa kungabonwa yisici esithi "izinsimbi" ezitholakala kuphaneli yangemuva yomsakazo. Inani lemiphumela yolayini liyahluka kumamodeli omsakazo ahlukene. Ngokuvamile kukhona amapheya okukodwa kuya kwamathathu. Ngokuyisisekelo, asakazwa ngale ndlela elandelayo: ipheya eli-1 - ungaxhuma i-subwoofer noma izipikha ezi-2 (ezisayinwe njenge-SWF) Uma kukhona amapheya amabili awo, ungaxhuma izipikha ezi-2 noma i-subwoofer nezipikha ezi-4 (okuphumayo kusayinwe ngo-F futhi SW), futhi uma kunamapheya angu-2 ezintambo eziqondile emsakazweni, ungakwazi ukuxhuma izipikha ezi-3 kanye ne-subwoofer (F, R, SW) F Lena yi-Front i.e. izipikha ezingaphambili, R Funda izipikha zangemuva, ne-SW Sabwoorer ngicabanga ukuthi wonke umuntu uyakuqonda lokho.

Ukuze uxhume, uzodinga i-interconnect wire, okungeke kwenzeke ukuthi ingagcinwa. Akuvunyelwe ukubeka intambo yokuxhuma eduze kwezintambo zamandla, ngoba izinhlobo ezahlukene zokuphazamiseka zizozwakala ngesikhathi sokusebenza kwenjini. Ungakwazi ukwelula izintambo kokubili ngaphansi komata baphansi nangaphansi kophahla. Inketho yokugcina ibaluleke kakhulu ezimotweni zanamuhla, ekhabetheni lapho kukhona izesekeli ze-elekthronikhi eziphazamisayo.
Udinga futhi ukuxhuma intambo yokulawula (REM). Njengomthetho, ifika nezintambo ezixhumanisayo, kodwa kwenzeka ukuthi azikho, zithenge ngokwehlukana, akudingekile ukuthi kube ingxenye enkulu yesiphambano esingu-1 mm2 kwanele. Le ntambo isebenza njengesilawuli sokuvula i-amplifier, okungukuthi uma uvala umsakazo, ivula ngokuzenzakalelayo i-amplifier yakho noma i-subwoofer. Njengomthetho, le ntambo emsakazweni iluhlaza okwesibhakabhaka ngomugqa omhlophe, uma kungenjalo, bese usebenzisa intambo eluhlaza okwesibhakabhaka. Ixhuma ku-amplifier kutheminali ebizwa ngokuthi i-REM.
Umdwebo wokuxhumeka kwe-amplifier
Ixhuma i-amplifier eneziteshi ezimbili kanye neziteshi ezine
Sihlanganise lesi sigaba, ngoba lezi zikhulisi zinesimiso sokuxhuma esifana kakhulu, kungashiwo kalula, i-amplifier eneziteshi ezine ineziteshi ezimbili. Ngeke sicabange ukuxhuma i-amplifier eneziteshi ezimbili, kodwa uma uthola ukuthi ungaxhuma kanjani i-amplifier eneziteshi ezine, ngeke ube nezinkinga zokuxhuma iziteshi ezimbili. Iningi labathandi bezimoto bakhetha le nketho ekufakweni kwabo, ngoba izipikha ezi-4 zingaxhunywa kulesi sikhulisamandla, noma izipikha ezi-2 kanye ne-subwoofer. Ake sibheke ukuxhuma i-amplifier eneziteshi ezine sisebenzisa inketho yokuqala neyesibili.
Ukuxhuma i-amplifier yamashaneli angu-4 kubhethri kuyanconywa kusetshenziswa ikhebula eliwugqinsi. Indlela yokukhetha izintambo zamandla ezifanele nokuxhuma izixhumi yikho konke esikuxoxile ngenhla. Uxhumo lwe-amplifier ngokuvamile lucaciswa emiyalweni evela kumkhiqizi. Uma i-amplifier ixhunywe kuma-acoustics, isebenza ngemodi ye-stereo; kule modi, lolu hlobo lwe-amplifier lungasebenza ngaphansi komthwalo we-4 kuya ku-2 ohms. Ngezansi kunomdwebo wokuxhuma i-amplifier eneziteshi ezine kuzipikha.
Manje ake sibheke inketho yesibili, lapho izipikha ne-subwoofer zixhunywe ku-amplifier eneziteshi ezine. Kulokhu, i-amplifier isebenza kumodi ye-mono, ithatha i-voltage eziteshini ezimbili ngesikhathi esisodwa, ngakho-ke zama ukukhetha i-subwoofer enokumelana kwama-ohms angu-4, lokhu kuzosindisa i-amplifier ekushiseni ngokweqile futhi ivikeleke. Ukuxhuma i-subwoofer ngeke kube yinkinga, njengomthetho, umenzi ubonisa ku-amplifier lapho angathola khona i-plus yokuxhuma i-subwoofer, nalapho i-minus. Bheka umdwebo wokuthi i-amplifier yesiteshi esi-4 ibhulwa kanjani.
Ukuxhuma i-monoblock (isikhulisi sesiteshi esisodwa)
Ama-amplifiers wesiteshi esisodwa asetshenziselwa injongo eyodwa kuphela - ukuxhuma ku-subwoofer. Isici esiphawulekayo sama-amplifiers alolu hlobo amandla anda. Ama-Monoblocks nawo ayakwazi ukusebenza ngaphansi kwama-ohms angu-4, okubizwa ngokuthi umthwalo ongamelani kancane. Ama-Monoblocks ahlukaniswa njengama-amplifiers ekilasi D, kuyilapho anesihlungi esikhethekile sokusika amaza.
Ukufaka i-amplifier yesiteshi esisodwa akudingi umzamo omkhulu, njengoba imidwebo yayo yokuxhuma ilula kakhulu. Kunemiphumela emibili isiyonke - "plus" kanye "nokususa", futhi uma isipika sinekhoyili eyodwa kuphela, udinga nje ukuyixhuma kuso. Uma sikhuluma ngokuxhuma izikhulumi ezimbili, khona-ke zingaxhunywa ngokufana noma ngochungechunge. Yiqiniso, akudingekile ukukhawulelwa kuzikhulumi ezimbili kuphela, kodwa ngaphambi kokuxhuma i-amplifier ne-subwoofer emsakazweni, ingabe laba bamuva bazobhekana nezinga eliphezulu lokumelana.
