Konke Okudingeka Ukwazi Ngama-Amplifiers Emoto
Ama-amplifiers agesi ahluleka ukubona, ngaphandle komqondo. Akudingeki ukuba ube isazi sokulalelwayo somsindo, noma ngisho nokuqaphelisisa, ukukhomba i-stereo yemoto yakho noma i-grills yakho yesipikha. Okufanayo akunjalo ngama-amplifiers, okuvame ukuhlotshaniswa nokulalelwayo kwemoto ephezulu.
Imisindo eminingi yemisindo yemoto ayifaki i-amplifier ehlukile, futhi ukuthuthukiswa komsindo wemoto okulula nakho kushiye isikhulumi. Kodwa iqiniso liwukuthi yonke imishini yomsindo wezimoto ngempela ihlanganisa i-amplifier, futhi i-stereo yakho ngokoqobo ngeke isebenze ngaphandle kweyodwa.
Iqiniso liwukuthi ngezinhlelo eziningi zomsindo wezimoto, i-amplifier yakhiwe eyunithi yekhanda. I-catch is ukuthi ngokuvamile ayinhle kakhulu.
Yini Amaplifiyeli Womsindo?
Kuzo zombili izinhlelo zomsindo wekhaya nemoto, i-amplifier iyisetshenziswa esithatha isignali yomsindo esibuthakathaka futhi siyikhulise. Isignali engena ku-amplifier inamandla kakhulu ukushayela izikhulumi, kanti isignali ephuma ingenza umsebenzi ufezeke.
Le nqubo yokukhulisa iyinxenye edingekile yohlelo olulodwa lwekhaya elilodwa neyomsindo , futhi amandla we-amp echaza ukuthi ukukhululeka okukhulu nokuphambene kangakanani umsindo kuyoba khona.
Njalo uhlelo lune-amp amp eyodwa, ngisho noma lwakhiwe kwiyunithi yekhanda, kanti ezinye zihlanganisa ngisho nangaphezulu. Isibonelo, kuvamile ukufaka imoto eyayizinikezele i-audio amplifier ukushayela i-subwoofer .
Ingabe Udinga Ngempela Amp Audio Audio?
Izinyunithi eziningi zekhanda ziqukethe ama- amplifiers akhiwe ngaphakathi, kodwa ngokuvamile ayinamandla kakhulu. Ama-head units aqukethe amps ezinamandla athambekele kakhulu ekupheleni kwezindleko, okwamanje ngokuvamile kuyisinqumo esingcono sokubambisana nekhanda eliyinhloko elifaka izimpendulo ze- preamp nge-amp dedicated.
Kunezizathu eziningi zokufaka ingxenye ehlukile ye-amplifier ohlelweni lwakho lokulalelwayo lwemoto, futhi nakanjani udinga eyodwa uma ufuna:
- Ukushayela umsindo ngaphandle kokuphazamiseka
- Ukunika amandla i- subwoofer
- Ukuthola okuningi kwezikhulumi zakho ezintsha
Uma ungacabangi ukuphazamiseka okuncane, futhi awunaso isifiso sokuchofoza i-unit yakho yekhanda ku-11, khona-ke kungenzeka ukuthi weqa i-amp bese ugxila ku-unit yakho yekhanda kanye nezipikha. Ezinye izinyunithi zekhanda zinamandla anele okuhlinzeka ngezwi elingafani nokungaziphambuki, futhi ukwengeza i- cross -pass crossover kungasiza ukucacisa izinto.
Esinye isici okufanele ucatshangelwe ukuthi ngabe i-unit yakho yekhanda ihlanganisa noma yikuphi ukukhishwa kwe-preamp. Lezi ziphumo zinyathelisa isikhulumi esakhelwe ngaphakathi futhi ithumele isignali ehlanzekile ku-amplifier yangaphandle.
Uma ikhanda lakho lekhanda lingenayo izimpendulo zangaphambili, kuzodingeka uthole i-amp eveza izimpendulo zezinga lesikhulumi. Okunye ukhetho ukusebenzisa ispikha kumguquli wezinga lokulayini. Nakuba zombili lezi zindlela zizothambekela ekusunguleni umsindo noma ukuphazamiseka, okunye okuwukukhetha ukuthenga ikhanda elisha lekhanda.
Ngenkathi ukuthuthukiswa kweyunithi yakho yekhanda ngaphambi kokwengeza i-amplifier kuhilela ukuchitha imali eyengeziwe, iyohlinzeka ngemiphumela engcono kakhulu. Uma usebenza neyunithi yekhanda ehloniphekile ukuqala, ukuthola imoto yemoto enhle kuyinkqubo elula kakhulu.
Iziteshi nezinye izici
Esinye sezici eziyinhloko ezihlukanisa phakathi kwe-amps yiziphi iziteshi eziningi abanayo. Zitholakala ekulungiselelweni okuningi, kusukela kumamashaneli ayisithupha kuya kweyisithupha, ngasinye esilandelayo kuzo zonke izilungiselelo zesipikha esihlukile.
Okungenani isiteshi esisodwa siyadingeka kwisipikha ngasinye, kodwa futhi kungenzeka ukusebenzisa okungaphezu kweyodwa amp in ohlelweni olulodwa lokulalelwayo lwemoto. Isibonelo, isiteshi se-4-channel singakwazi ukunikeza izikhulumi ezine ze-coaxial, futhi i-mono amp ehlukile ingasetshenziselwa i-subwoofer.
Kukhona nokuhlelwa kwesiteshi okuhlukile okuzosebenza kangcono nezikhulumi zezingxenye, ngakho-ke i-amp ngayinye kufanele ifaniswe nesistimu ukuthi iya emandleni. Amanye ama-amps anesiphuphu esincane noma amaphuzu aphezulu awakhiwe ngaphakathi, okwenza ukuba afaneleke ngokuphelele ukunika amandla ama-woofers noma ama-tweeters. Ezinye izitshalo zinezihlungi eziguquguqukayo, ukukhushulwa kwe-bass, nezinye izici.
Ukubaluleka kwamandla
Amandla we-amp akhuluma ngamattery angathumela kuzikhulumi. Njengoba iphuzu lonke le-amplifier ukwandisa amandla esignali yomsindo, amandla e-amp isesinye sezibalo ezibaluleke kakhulu.
Inani eliyinhloko lapha i- RMS , kodwa ayikho inombolo ethize okufanele ibuke. I-RMS ye-amp kufanele ifaniswe nokuphathwa kwamandla kwezikhulumi, okuhlukile kuzo zonke izinhlelo zomsindo wezimoto.
I-ratio enkulu yokudubula yona i-RMS ephakathi kwamaphesenti angama-75 no-150 wamandla izikhulumi ezingakwazi ukusingatha, futhi ukunqoba amandla izikhulumi kancane kuncono kunokuzikhandla ngamandla.
