Indlela kuphela yokufinyelela amabhasi amahle kakhulu ane-subwoofer, kodwa ukunquma ukwengeza i-sub kuya kokusetha kwe-audio yakho kuyisinyathelo sokuqala ohambweni olude. Wonke amandla adingekayo ukuze ukondle i-sub yakho elambile kufanele ivela endaweni ethile, futhi ukuthi endaweni ethile yikhuliseli. Umbuzo ungayikwazi yini ukuthi ukhona kakade, noma udinga ngempela ukwengeza i-subwoofer amplifier ezinikezele ngesikhathi esifanayo wengeze i-sub sub?
Impendulo iyinkimbinkimbi, futhi ixhomeke kakhulu ezintweni ezinjengokuthi ufuna ukuchitha imali engakanani futhi ukuthi ukhethe kangakanani indlela umkhiqizo oqedile uzwakala ngayo. Kunezindlela ezizwakalayo zokwenza umsebenzi okhona we-amp nge-sub, kepha imiphumela emihle ivela njalo ngokufanisa i-subwoofer kanye ne-amplifier ukuqinisekisa ukuthi basebenza ndawonye ngokuvumelana okuhle.
Ubani odinga i-Amplifier ye-Subwoofer?
Impendulo emfushane yukuthi wonke umuntu ofuna i-subwoofer emotweni yawo futhi udinga i-subwoofer amplifier. Ngokuqondene nokuthi udinga amp amp ehlukile ye- subwoofer yakho, lokho kuxhomeke kwi-hardware osuvele nayo kanye nesistimu yomsindo wezimoto ozama ukwakha . Njengoba wonke umuntu efuna okuthile okungafani nakakhulu ohlelweni lwawo lwezomsindo wezimoto, azikho izimpendulo ezingalungile ngempela, kodwa mhlawumbe kukhona impendulo engcono kakhulu ngesimo sakho.
Kuyini ukufana okufana ne-Subwoofer ne-Amplifier?
Uma ubheka imininingwane ye-subwoofer enikeziwe, iyoba nen impedane efakwe kuma-ohms. Le nombolo ngokuyisisekelo umthwalo ukuthi i-sub izobe ibeke ku-amplifier. Njengoba ama-amplifiers akhipha amandla kuye ngokuthi umthwalo onamathele, kubalulekile ukuqinisekisa ukuthi lezi zinombolo zihambisana.
Izibalo eziyinhloko yi-impedance, kulinganiswa kuma-ohms, nokukhipha amandla. Kulesi simo, ukukhishwa kwamandla kunikezwa njenge- watts impande-mean-square (RMS). Ngokusho kwe-subwoofer, i-watts i-RMS ibhekisela ekutheni amandla angaphansi angakwazi ukuphatha ngaphandle kokukhiqiza ukuphazamiseka noma ukulimala. Ohlangothini lwe-amplifier, libhekisela kumandla angakanani amp amp.
Izinyathelo eziyisisekelo ekufaniseni i-amplifier kwi-subwoofer yilokhu:
- Hlola isilinganiso se-watts se-RMS se-sub yakho noma ye-subs.
- Hlela impedance ye-sub yakho noma ye-subs.
- Khetha i-amplifier engakwazi ukubeka phakathi kwamaphesenti angaba ngu-75 kuya kwangu-150 we-Watts i-RMS i-subwoofer yakho engayisingatha empikeni efanelekile.
Uma usuvele une-amplifier, izinyathelo eziyisisekelo zokuthola i-sub efanayo:
- Hlola ukukhishwa kwamandla wam amp, ku-Watts RMS, ngezindinganiso ezahlukene ze-impedance.
- Hlukanisa amandla okukhipha ngenani le-subs ofuna ukuyengeza ukuze uthole inani elilinganiselwe le-RMS ngayinye ye-subwoofer. Ngokwenzayo, i-subwoofers ingaba phakathi kwamaphesenti angu-75 no-150 ale namba.
- Qinisekisa ukuthi impedance iyafana. Ukubhalwa ngamakhoyili amaningi wezwi kungavame ukuhanjiswa ngezindlela eziningi, okuthinta impedance.
- Khetha ama-subwoofers angakwazi ukusingatha ukukhipha amandla okufanele emkhawulweni okhethiwe.
Ukunika amandla i-Sub: Amps Amanethiwekhi amaningi nama-Amono Subwoofer Amps
Njengomthetho jikelele wesithupha, i-subwoofer yakho izodinga amandla angaphezu kwesinye isici sakho noma izikhulumi eziphelele. Ngisho ne-sub encane izovame ukufuna ama-watts angama-50 angaphezu kuka-50, okungaphezu kwama- amplifiers akhethiwe ngaphakathi kwamayunithi amaningi ekhanda angafaka inani.
Uma uqala ukungena ku-subs bigger edinga ngaphezulu kwama-watts angu-200 e-RMS ukuze uzwakale kahle, iqala ukucaca ukuthi ngeke ubalekele ngaphandle komkhiqizo wangaphandle wohlobo olulodwa noma olunye. Kodwa-ke, unakho ukhetho lokuhamba nam amp amp channel noma amp dedicated subwoofer amp.
Ngaphandle kokwazi lutho mayelana ne-amp, usunzima ukukusho ukuthi uzokwenza yini iqhinga le-sub yakho entsha. Uma usuvele usebenzisa zonke iziteshi ukushayela izipikha, khona-ke ungaphandle kwenhlanhla. Uma une amp amp channel yomzila eneziteshi ezimbili ezivulekile, ungase ukwazi ukuyisebenzisa ukuze unike amandla izikhulumi ezimbili eziphelele zezinhlayiyana kanye ne-sub, nakuba imininingwane yalolu hlobo lokusetha ingathola okuncane kabi.
Ukubhanqa Amps Amanethiwekhi Amandla Ase-Multiwoofer Amps
Ukuze usebenzise amamaki amaningi wesiteshi amandla, uvame ukushayela iziteshi ezimbili, futhi lokho akusebenzi ngaso sonke isikhathi ngama-amp. Into ebalulekile ukuqonda lapha ukuthi ama-amps amaningi azinzile kuze kube ngu-2 ohms ngesiteshi ngasinye.
Uma uzama ukubamba umthwalo onemikhawulo engaphansi kwe-2 ohms, uzongena enkingeni. Njengoba cishe zonke izikhulumi zezinhlawulo ezigcwele ongazitholela imoto yakho ziyoba nempumelelo ye-4 ohms, lokhu ngokuvamile akuyona inkinga. Noma kunjalo, kungaba yinkinga uma uphonsa ama-subwoofers ku-mix.
Ngokungafani nezikhulumi ezihamba phambili ezigcwele , ukubhaliswa kwemoto akuhlinzeki konke okungu-4 ohms of impedance. Eqinisweni, i-subs ingaba namakhoyili amaningi wezwi, okungase kube nzima nakakhulu ngale ndaba. Isibonelo, i-sub ezinamalahle amabili wezwi angu-4 ohm, ifakwe ngephambano, izohlinzeka ngomthwalo o-2 ohm, kodwa lezo zindwangu zezwi ezifanayo zifakwe ochungechungeni zinikeza umthwalo we-8 ohm. Lokhu kusho ukuthi uma ubhuqa imigudu emibili ndawonye, ngokujwayelekile uyobe wenza amandla aphikisanayo-2 ohm sub, kodwa kubalulekile ukuthi ubheke kanzima izinombolo kuqala.
I-Mono Subwoofer Amps
Indlela elula yokusebenzisa iphansi elincane ukulihlanganisa nje nge-mono amp. Ngokungafani nama-amps amaningi wesiteshi, ama-mono amps aklanyelwe nge-subs engqondweni. Esikhundleni sokungena ngokuzungezile ngokukhipha imigudu emibili, umane uhlanganise isiteshi esisodwa se-mono amp kuya ku-subwoofer ehambelanayo, futhi kuhle ukuhamba. Uma usanda kushayisana nezwe le-amps ne-subs, futhi uya emgwaqweni we-DIY, lokhu nakanjani ukubheja okuphephile.
Ukuze uthole umsindo ongcono kunazo zonke ezingxenyeni zakho ezintsha, uzofuna ukuhamba nge-mono amp enesilinganiso se-RMS okungenani amaphesenti angama-75 we-sub. Uma usebenzisa amandla amaningi ukushayela i-sub, kungcono ukuphela kokukhala, ngakho-ke uma ungakwazi ukuyiqhubekela phambili kuze kube amaphesenti angu-100 uzophela ngemiphumela engcono kakhulu.
Ukungeza i-Subwoofer Amp ku-Multi-Amp Systems
Uma usuvele unamaphakheji akho aphelele webala, futhi ufuna ukwengeza i-mono amp entsha kwisistimu yakho, izinketho zakho zizoxhomeka ekhanda lakho lekhanda. Ezinye izinyunithi zekhanda zinemiphumela eminingi ye- preamp , lapho ungafaka khona kuphela ukusetha iqoqo elisha lezintambo ze-RCA zibe yisikhwama esingasetshenziswanga bese ubambelela ku-amp subofofer yakho entsha.
Ezinye izinyunithi zekhanda zinomthwalo owodwa wemiphumela ye-preamp, uma ngabe uzofuna ukuhlola amp yakho ekhona. Uma ine-pass-through (kufaka phakathi isethi yemiphumela yangaphambili ye-RCA) ngakho-ke ungakwazi ngokuyisisekelo-chain chain yakho entsha ye-subwoofer kumakhuliseli osuvele unawo. Uma kungenjalo, kungadingeka ukuthi usebenzise ikhebula lehlukanisa Y.
