I-amplifier yangaphambili ye-subwoofer

Abathandi bomculo noma ukubukela amabhayisikobho esikrinini esikhulu semidlalo yaseshashalazini basekhaya banesithakazelo sokuthola umsindo ophezulu. Yingakho kubalulekile ukuthi isiphi isikhangiso esandulela ukukhetha, ukuze umphumela ungakusizi, yiziphi izici okufanele unake lapho ukhetha idivayisi yomsindo.

Uma ulalela umculo kumdlali we-CD, i-amplifier nayo iyadingeka, ngoba isignali ibuthakathaka kakhulu. I-amplifier ixhunyiwe kuzikhulumi. Iyakwazi ukushintsha nokuthola isignali yomsindo, ukuyikhulisa kuvolumu edingekayo.

Ama-amplifiers ahlukaniswe abe izinhlobo ezintathu: okuqala, okubalulekile nokukhulisa amandla. I-Integral, ehlanganisa yonke into ephaketheni elilodwa, okwamanje iyona evame kakhulu. Okubiza kakhulu futhi okunembile yiluhlelo lwedivaysi ehlukile, olune-amplifier yamandla kanye ne-preamplifier. Amaplifiers yi-tube, i-transistor.

Kuyinto inguquko yokuqala ekwazi ukunikeza umculi womculo wamanje ozwakalayo ongathanda ukuwuzwa - okuhlanzekile nakakhulu okulinganayo, okuphilayo ngempela.

Ukukhetha kusuka kusigaba sama-digital multichannel amadijithali abizayo, ungahlala ku-processor ye-AV. Futhi uma ukhetha phakathi kwama-amplifiers, kungcono ukunikeza okuthandayo ku-preamplifier, okuyiyona imali engcono kakhulu yokutshalwa kwemali. Iprosesa iyakwazi ukulungisa kahle imingcele nokucubungula umsindo ozungezile. Ngenxa yalokho, ungakwazi ukuhlanganisa uhlelo olulalelwayo olulandelayo, kufaka phakathi umthombo (isibonelo, i-disc player), i-preamplifier, amplifier nama-acoustics. Njengomthombo ungasebenza njenge- turntable yamarekhodi e- vinyl , i-cassette yedokodo kanye nezinye izinketho. Esikhundleni se-preamplifier, ungasebenzisa i-processor ye-AV. Ama-pre-amplifiers asebenza kahle ngokuhambisana nezinhlelo zomsindo wedijithali, lapho abumba khona amaphaphu amandla. Lokhu kuvumela umnikazi we-acoustics ezobuchwepheshe ukugwema ukurekhoda komculo lapho edlala amaphutha futhi emuva kokunciphisa ama-freon resonances avela ekamelweni.

Ukwenza i-preamplifier ye-subwoofer ikhiqize izinga elizwakalayo elizwakalayo, kuyadingeka ukusetha imvamisa yesikhungo sayo eduze kwekhilomitha eyodwa ku-equalizer yayo, bese unciphisa i-midrange ibe yingxenye ye-decibel.

Ukuze ulungise umsindo ku-preamplifier, ukhiqize ukukhishwa kwawo okuphezulu, futhi ekufakeni ku-amplifier yamandla ngezinga eliphansi. Umsindo uzoba ngcono uma impedance yomkhiqizo we-preamplifier iphansi kunomthelela wokufaka amandla we-amplifier yamandla. I-stereo amplifiers nezibani zokukhulisa amandla kagesi zihlangene kahle. Ungakwazi ukuxhuma inguqulo yokuqala kuzikhulumi ezisebenzayo, kodwa umsindo omuhle ungatholakala kuphela ngokusebenzisa izinhlobo ze-studio eziphezulu.

Ngokuvamile, i-preamplifier idlala indima yesilawuli sokulawula evumela ukuthi ulungise ivolumu kanye nesimiso sesistimu yomsindo, ushintsha imithombo yomsindo futhi ulungisa isignali ye-amplifier yamandla. Ngokungafani nalokhu okulandelayo, i-preamplifier ifakwe ngokucacile.

Uma ukhetha i-pre-amplifier yekhwalithi eliphezulu, khona-ke lokhu kuyindlela yokwenza isigaba "High End", isibonelo, "Evolution", eyenziwe ngabakhiqizi baseJalimane. Ifeza ukungathathi hlangothi okuphezulu ngokucubungula isignali yomsindo wokufaka. Idivayisi ine-element element ephelele, indlela emfushane yesignali kanye nokunikezwa kwamandla okuzinzile. I-Pre-Silicon ine-mono ekhishwe ku-subwoofer enezifinyezo ze-satellite, ingafakwa ngaphakathi kwe-tuner kanye ne-phono pre-amplifier jikelele. Ngokungangabazeki, idivaysi enjalo ingakwazi ukujabulisa abaningi abathandi bomculo bangempela.
