Njira yokhayo yomwe mungapezere mabasi abwino kwambiri ndi subwoofer, koma kusankha kuwonjezera gawo lanu kukonzekera kwa galimoto yanu ndilo gawo loyamba la ulendo wautali. Mphamvu zonse zomwe zikufunikira kudyetsa gawo lanu la njala ziyenera kubwera kuchokera kwinakwake, ndipo kuti penapake pali amplifier. Funso ndilo kodi mungagwiritse ntchito ndi amp amp, kapena mukufunikiradi kuwonjezera gawo lopatulira la subwoofer panthawi imodzimodziyo pamene muwonjezere gawo lanu?
Yankho lake ndi lovuta, ndipo zimadalira zinthu monga ndalama zomwe mukufuna kugwiritsa ntchito komanso momwe mumasankhira za momwe mankhwala omalizira amvekera. Pali njira zenizeni zopangira ntchito yamakono ndi sub, koma zotsatira zabwino zimachokera poyenderana ndi subwoofer ndi amplifier kuti atsimikizire kuti amagwirira ntchito pamodzi mogwirizana.
Ndani Akufunikira Amplifier?
Yankho lalifupi ndilo kuti aliyense amene akufuna subwoofer m'galimoto yawo amafunikanso kutsegulira pansi. Kuti mudziwe ngati mukufunikira amphamvu yamtundu wanu wa subwoofer , zimadalira hardware yomwe muli nayo kale ndi galimoto yanu yomwe mukuyesa kumanga . Popeza aliyense akufuna chinachake mosiyana ndi kachitidwe ka galimoto yawo, palibe kwenikweni mayankho olakwika, koma mwina pali yankho labwino pazochitika zanu.
Kodi Subwoofer ndi Amplifier zikugwirizana bwanji?
Mukayang'ana pazomwe zimaperekedwa kwa subwoofer iliyonse, idzakhala ndi mpweya wotchulidwa mu ohms. Nambalayi kwenikweni ndi katundu amene gawoli lidzaikapo pamphamvu. Popeza amplifiers amachotsa mphamvu malingana ndi katundu umene waikidwa, ndikofunika kutsimikiza kuti manambalawa akuyendera.
Manambala ofunika kwambiri ndi impedance, yoyezedwa mu ohms, ndi mphamvu yotulutsidwa. Pachifukwa ichi, mphamvu zotulutsidwa zimaperekedwa monga watts mizu-mean-square (RMS). Malinga ndi subwoofer, watchi a RMS amasonyeza kuti mphamvu zomwe zingathe kugwiritsidwa ntchito zingapangitse bwanji kusokoneza kapena kuwonongeka. Pa mbali ya amplifier, iyo imatanthawuza kuchuluka kwa mphamvu amp amphamvu.
Zowonongeka zowonetsera zowonjezeretsa ku subwoofer ndi izi:
- Sankhani mlingo wa watts wa RMS wa sub yanu kapena subs.
- Tsimikizani kutsika kwa gawo lanu kapena kubwereza.
- Sankhani amplifier yomwe ingatulutsire pakati pa 75 mpaka 150 peresenti ya Watts RMS wanu subwoofer ingathe kuthana nayo pamsana woyenera.
Ngati muli ndi amplifier, njira zofunikira kuti mupeze zotsatira zofanana ndizo:
- Sankhani mphamvu ya amp amp, mu watts RMS, pazinthu zosiyana siyana zamthambo.
- Gawani mphamvu yotulutsidwa ndi chiwerengero cha subs yomwe mukufuna kuwonjezera kuti mupeze phindu loyenera la RMS pa subwoofer iliyonse. Mwachizolowezi, subwoofers ikhoza kukhala pakati pa 75 ndi 150 peresenti ya nambala iyi.
- Onetsetsani kuti impedance ikugwirizana. Kutumizirana ndi makina ambiri a voliyumu kawirikawiri kumawombedwa m'njira zosiyanasiyana, zomwe zimakhudza impedance.
- Sankhani subwoofers zomwe zingagwiritse ntchito mphamvu yoyenera kutuluka pamsana wosankhidwa.
Kulimbitsa gawo: Ma Amps Multichannel ndi Mono Subwoofer Amps
Monga lamulo lachiphindi, subwoofer yanu idzafuna mphamvu yoposa mphamvu yanu yina kapena oyankhula bwino. Ngakhale kachigawo kakang'ono kawirikawiri kawirikawiri amafunika kupitirira 50 Watts RMS, omwe ali oposa amphamvu mu makutu ambiri mutu akhoza kutulutsa chiwerengero.
Pamene muyamba kulowa muwuni yapamwamba yomwe ikufunika kupitirira 200 Watts RMS kuti imve bwino, imayamba kuonekera kuti simudzathawa popanda kunja kwa mtundu umodzi kapena wina. Komabe, muli ndi mwayi wopita ndi amphamvu zamagetsi amphamvu kapena mono subwoofer amp.
Popanda kudziwa chilichonse chokhudza amp amphamvu muli nayo, ndizovuta kunena ngati mukuchita chinyengo cha gawo lanu latsopano. Ngati mukugwiritsa ntchito njira zonse zoyendetsa okamba, ndiye kuti mulibe mwayi. Ngati muli ndi amphamvu zamakono amphamvu ndi njira ziwiri zotseguka, ndiye mutha kuzigwiritsa ntchito kuti mukhale ndi mphamvu pa okamba awiri omwe ali oyankhula bwino ndi gawo, ngakhale kuti zolemba za mtundu uwu zingakhale zovuta pang'ono.
Kumanga Amps Multi-Channel Subwoofer Amps
Kuti mugwiritse ntchito mphamvu zamagetsi zamagetsi pansi, mumayenera kugwiritsa ntchito njira ziwiri, ndipo nthawi zonse sizigwira ntchito ndi amphamvu. Chinthu chofunikira kumvetsetsa apa ndikuti maimps ambiri amakhala osasunthika mpaka 2 ohms pa kanjira.
Ngati mutayesa kuyika katundu umene uli ndi mphambu yosachepera 2 ohms, mutha kulowa muvuto. Popeza pafupifupi onse okamba nkhani omwe mungathe kupeza galimoto yanu adzakhala ndi mpweya wa 4 ohms, izi sizingakhale vuto. Komabe, zingakhale zovuta mukamaponya subwoofers mu kusakaniza.
Mosiyana ndi omvera okwera , maulendo a galimoto samapereka 4 ohms of impedance. Ndipotu, pulogalamuyi imatha kukhala ndi makalata ambiri, omwe angapangitse nkhaniyo kukhala yowonjezereka. Mwachitsanzo, gawo limodzi ndi ma voil awiri a 4 ohm, olumikizidwa mofanana, lidzapereka 2 ohm load, koma ma voil omwewo amalumikizidwa mndandanda amapereka 8 ohm load. Izi zikutanthauza ngati mutagwirizanitsa njira ziwiri palimodzi, mutha kukhala ndi mphamvu yofanana ndi yowonjezera, komabe n'kofunika kuyang'ana mozama ma nambala yoyamba.
Mono Subwoofer Amps
Njira yosavuta yowonjezera gawo latsopano ndikungoliphatikiza ndi mono amp. Mosiyana ndi ma-amps angapo, ma-amps amadzipangidwira ndi kukumbukira. M'malo mozungulirana ndi kulumikiza njira ziwiri, mumangoyang'ana njira imodzi ya mono amp to a subwoofer yofanana, ndipo ndibwino kupita. Ngati muli watsopano ku dziko la amps ndi subs, ndipo mukupita njira ya DIY, izi ndizovuta kwambiri.
Kuti mupeze phokoso lomveka bwino kuchokera kumagulu anu atsopano, mukufuna kupita ndi mono amp yomwe ili ndi chiwerengero cha RMS cha magawo 75 peresenti ya gawoli. Mphamvu yomwe mumagwiritsira ntchito kuyendetsa gawoli, ndibwino kuti phokoso lidzatha, kotero ngati mutha kulikweza mpaka kufika pa 100 peresenti mudzatha ndi zotsatira zabwino kwambiri.
Kuwonjezera Amp Subwoofer mu Multi-Amp Systems
Ngati muli ndi amphamvu anu okamba bwino, ndipo mukufuna kuwonjezera mono amp yanu m'dongosolo lanu, zosankha zanu zidzadalira mutu wanu. Mipira ina yamutu imakhala ndi zochitika zambirimbiri , pomwe mungathe kubudula zingwe zatsopano za RCA muzogwiritsidwa ntchito osagwiritsidwa ntchito ndikuzilowetsa ku gawo lanu latsopano la subwoofer amp.
Mipira ina yamutu imangokhala ndi imodzi yokha yoyambira, pomwe mungayang'ane amp amp yanu. Ngati ali ndi kudutsa (kuphatikizapo zida za RCA preamp) ndiye kuti mumatha kusungunula latsopano subwoofer amp kwa amplifier omwe muli nawo kale. Apo ayi, mungagwiritse ntchito chingwe cha Y splitter.
