Ukukhetha i-amplifier yesistimu yakho yomsindo

Uma ubheka nje, kungase kubonakale sengathi inqubo yokukhetha i-amplifier emotweni yezikhulumi noma i-subwoofer ayilula kangako. Kodwa ukuba nemfundo emfushane "Indlela yokukhetha i-amplifier" ngeke kubangele izinkinga. Inhloso ye-amplifier yesistimu yomsindo ukuthatha isignali yezinga eliphansi bese uyiguqulela kusignali yezinga eliphezulu ukuze ushayele isipikha.

Angase ahluke ngenani lamashaneli okukhulisa amandla, amandla kanye nezindleko. Ama-amplifiers amabili namashaneli amane adingeka kakhulu kubashayeli. Futhi manje ake siphendule umbuzo wokuthi ungakhetha kanjani i-amplifier emotweni ngokuningiliziwe.

Amakilasi Okukhulisa Izimoto

Okokuqala, ngithanda ukukhuluma ngamakilasi we-amplifier, okwamanje kukhona inani elikhulu lawo, kodwa sizocabangela ezimbili eziyinhloko ezivame kakhulu ezinhlelweni zomsindo wemoto. Uma unesithakazelo kulesi sihloko ngokuningiliziwe, ekupheleni kwesihloko kukhona ividiyo ekhuluma ngawo wonke amakilasi ama-auto amplifiers asetholakala manje.

• I-amplifier yekilasi AB. Lawa ma-amplifiers anekhwalithi yomsindo enhle kakhulu, ngokuxhumeka okufanele athembekile futhi aqinile. Uma i-amplifier yesigaba se-AB inamandla aphezulu, ngakho-ke inobukhulu obukhulu kakhulu, lezi zikhulisi zinokusebenza okuphansi okungaba ngu-50-60%, okungukuthi uma ama-watts angu-100 efakwa kuzo. amandla, khona-ke i-current of 50-60 watts izofinyelela izikhulumi. Amandla asele avele aguqulwe abe ukushisa. Akunakwenzeka ukufaka ama-amplifiers ekilasi le-AB endaweni evaliwe, ngaphandle kwalokho, lapho kushisa, kungangena ekuvikelweni.
• I-amplifier ye-Class D (i-amplifier yedijithali). Ngokuyisisekelo, isigaba sika-D sitholakala kuma-monoblocks (ama-amplifiers esiteshi esisodwa), kodwa kukhona neziteshi ezine nezimbili zokuxhuma ama-acoustics. Le amplifier inezinzuzo eziningi. Uma kuqhathaniswa nesigaba se-AB, esinamandla afanayo, sinobukhulu obuhlangene kakhulu. Ukusebenza kahle kwalawa ma-amplifiers kungafinyelela ku-90%, empeleni akushisi. Ikilasi lika-D lingasebenza ngokuzinzile ngaphansi komthwalo we-ohmic ophansi. Konke kuzolunga, kodwa ikhwalithi yomsindo yalezi zikhulisa-msindo ingaphansi kwesigaba se-AB.

Siphetha lesi sigaba ngesiphetho. Uma ujaha ikhwalithi yomsindo (SQ), khona-ke kuyoba okulungile kakhulu ukusebenzisa izikhulisamazwi zekilasi AB. Uma ufuna ukwakha isistimu enomsindo kakhulu, khona-ke kungcono ukhethe izikhulisamazwi zeClass D.

Inani lamashaneli amplifier.

Iphuzu elilandelayo elibalulekile yinombolo yeziteshi ze-amplifier, kuya ngokuthi yini ongayixhuma kuyo. Konke kulula lapha, kodwa ake sihlolisise:

         

• Ama-amplifiers esiteshi esisodwa, abizwa nangokuthi ama-monoblocks, aklanyelwe ukuxhuma ama-subwoofers, ngokuvamile anesigaba D kanye nekhono lokusebenza ngokumelana okuphansi. Izilungiselelo (isihlungi) zenzelwe i-subwoofer, okungukuthi uma uxhuma isipikha esilula ku-monoblock, izokhiqiza kabusha i-bass yamanje.

 

• Ama-amplifiers aneziteshi ezimbili, njengoba ungase uqagele, ungakwazi ukuxhuma izipikha ezimbalwa kuwo. Kodwa futhi ama-amplifiers amaningi aneziteshi ezimbili angasebenza ngemodi ehlanganisiwe. Kulapho i-subwoofer ixhunywe eziteshini ezimbili. Lawa ma-amplifiers anezilungiselelo zendawo yonke (isihlungi), okungukuthi anokushintsha kwe-HPF, le modi ikhiqiza amaza amanje aphezulu, futhi lapho ushintshela kusihlungi se-LPF, i-amplifier izokhipha amaza aphansi (lesi silungiselelo siyadingeka ku-subwoofer).
• Uma uqonda ukuthi iyini i-amplifier eneziteshi ezimbili, khona-ke yonke into ilula ngeziteshi ezine, lezi zingama-amplifiers amabili eziteshi ezimbili, okungukuthi ungaxhuma izipikha ezine kuwo, noma izipikha ezi-2 ne-subwoofer, ezimweni ezingavamile ama-subwoofers amabili. ixhunyiwe, kodwa asikukhuthazi ukwenza lokhu. I-amplifier izoshisa kakhulu futhi ngokuzayo ingase ingasebenziseki.
  
  Ama-amplifier amashaneli amathathu nahlanu ayivelakancane kakhulu. Konke kulula lapha, ungaxhuma izipikha ezimbili kanye ne-subwoofer ku-amplifier eneziteshi ezintathu, izipikha ezi-4 kanye ne-subwoofer ku-amplifier eneziteshi ezinhlanu. Banazo zonke izihlungi zokulungisa izingxenye ezixhunywe kuzo, kodwa njengomthetho, amandla alawa ma-amplifiers mancane.

Sengiphetha, ngithanda ukusho okulandelayo. Uma umusha kumsindo wemoto futhi ufuna ukuthola umsindo wekhwalithi ephezulu, olinganiselayo, sikweluleka ukuthi ukhethe i-amplifier eneziteshi ezine. Ngayo, ungakwazi ukuxhuma izipikha zangaphambili kanye ne-subwoofer engenzi lutho. Lokhu kuzokunikeza ikhwalithi yangaphambili enamandla, esekelwa isixhumanisi se-subwoofer.

Amandla esikhulisi.

Amandla angenye yemingcele ebaluleke kakhulu. Okokuqala, ake sithole ukuthi uyini umehluko phakathi kwamandla alinganiselwe namandla aphezulu. Okwakamuva, njengomthetho, kukhonjiswe ku-amplifier case, ayihambisani neqiniso futhi isetshenziswa njengepasi lephromo. Lapho uthenga, naka amandla alinganiselwe (RMS). Ungabuka lolu lwazi emiyalweni, uma imodeli yesipika yaziwa, ungathola izici ku-inthanethi.

Manje amagama ambalwa okuthi ungakhetha kanjani amandla we-amplifier nezipikha. Ingabe ufuna ukufunda okwengeziwe mayelana nokukhetha isipikha? funda isihloko esithi "indlela yokukhetha ama-acoustics emoto". Izipikha zezimoto nazo zinamandla alinganiselwe, emiyalweni ebizwa nge-RMS. Okusho ukuthi, uma i-acoustics inamandla alinganiselwe angama-watts angu-70. Khona-ke amandla okuzisholo amplifier kufanele cishe efanayo, kusukela 55 kuya 85 Watts. Isibonelo sesibili, hlobo luni lwe-amplifier oludingekayo ku-subwoofer? Uma sine-subwoofer enamandla alinganiselwe (i-RMS) angama-watts angu-300. Amandla we-amplifier kufanele abe ngama-watts angama-250-350.

Isiphetho sesigaba. Amandla amaningi mahle impela, kodwa akufanele uwajahe, ngoba kukhona ama-amplifiers anamandla amancane, futhi adlala kangcono kakhulu futhi akhulume kakhulu kunalawo angambi eqolo kodwa anokusebenza okuphezulu esibhakabhakeni.

Igama lomkhiqizi.

 

Lapho uthenga i-amplifier, kubaluleke kakhulu ukunaka ukuthi yimuphi umkhiqizi oyenzile. Uma uthenga umkhiqizo wezandla, awukwazi ukuthembela kukhwalithi enhle yomsindo. Kungcono ukuphendukela kuma-crazy brand abesemakethe isikhathi eside futhi asevele ahlonishwe futhi azisa isithunzi sabo. Ngokwesibonelo, izinkampani ezifana Hertz, Alpine, DLS, Focal. Kusuka kweminye yesabelomali, ungagxilisa ukunaka kwakho kumabhrendi anjengokuthi; I-Alphard, i-Blaupunkt, i-JBL, i-Ural, i-Swat, njll.

Unqume ukukhetha i-amplifier? Isihloko esilandelayo esizoba usizo kuwe "indlela yokuxhuma i-amplifier yemoto."

Indlela yokukhetha i-amplifier emotweni (ividiyo)

Ama-Amplifaya we-SQ. Indlela yokukhetha i-amplifier emotweni

Yiqiniso, lezi akuzona zonke izinkomba okufanele uzinake lapho ukhetha i-amplifier, kodwa yizona eziyinhloko. Ngokulandela izincomo ezivezwe esihlokweni, ungakhetha i-amplifier ehloniphekile yesistimu yakho yomsindo. Sithemba ngempela ukuthi siphendule umbuzo wakho mayelana nendlela yokukhetha i-amplifier yezikhulumi noma i-subwoofer, kodwa uma usenawo amaphuzu angacacile noma izifiso, sizokujabulela ukuphendula kumazwana angezansi!
