Ngati mukugula amplifier kapena okamba atsopano, ndikofunikira kulabadira kusokoneza kwa aliyense. Chifukwa chiyani? Chifukwa kusagwirizana kungawononge kwambiri wina kapena mzake. Tiyeni tiwone momwe tingapewere izi.
Zinthu zamagetsi
Ndizovuta kulankhula za ohms popanda kutchula zinthu zina zamagetsi. Chifukwa chake tisanadumphire mozama mu ohms, tiyeni tiwone mbali zonse za siginecha yamagetsi momwe zimagwirira ntchito pamawu.
Magetsi ali ndi zigawo zinayi zofunika: volts, amps, ohms ndi watts. Voltage ndi mphamvu ya siginecha, pomwe ma amps amayezera pakali pano, zomwe mutha kuganiza kuti magetsi akuyenda mwachangu bwanji. Ohms kuyeza kukana, komwe, ngati mukuganiza kuti chizindikirocho ndi madzi oyenda, chimakhala ngati kukula kwa chitoliro chomwe chikuyenda.
Nanga bwanji ma watts? Ma Watts amayesa mphamvu yonse, yomwe ndi magetsi ochulukitsidwa ndi apano. Kuwonjezeka kwa magetsi kapena magetsi kumawonjezera ma watts onse a dongosolo lopatsidwa.
Tsopano tiyeni tiwone chifukwa chake kukana, kuyeza mu ohms, kuli kofunika kwambiri.
Kuyang'ana Kwambiri pa Ohms
Chifukwa ma ohms amayezera kukana, kuchuluka kwa chiwerengerocho, ndikokwera kwambiri kukana. Mfundo yakuti nambala yotsika imakhala ndi chizindikiro champhamvu ndi gawo lalikulu la chifukwa chake anthu amatha kusokonezeka pankhani ya ohms poyamba.
Apanso, ngati mukuganiza za siginecha yomvera kuchokera ku amplifier ngati madzi akuyenda kuchokera ku spout, mutha kuganiza za wokamba ngati chitoliro. Mutha kupopa madzi onse omwe mukufuna papaipiyi, koma pakapita nthawi madzi sangayendenso papaipiyi.
Pongoganiza kuti amplifier ndi speaker adavotera kukana eyiti ya ohm, chilichonse chimagwira ntchito momwe chiyenera. Amplifier sangayese kupopa zambiri kuposa momwe woyankhulira angagwirire.
Koma chimachitika ndi chiyani ngati muli ndi vuto? Tiyerekeze kuti muli ndi amplifier eyiti ohm koma ma speaker anayi ohm. Pankhaniyi, amplifier sangathe kupereka zokwanira panopa chifukwa kukana ndi otsika kuposa ake. Zili ngati kuthira madzi okwanira lita imodzi pansi pa chitoliro chomwe chingagwire kwambiri nthawi iliyonse.
Nthawi zina, ndi bwino. Mwa zina, amplifier adzayesa kupopera panopa mokwanira kuti agwirizane ndi kutsutsa kwa wokamba nkhani, komwe kumakhala kotsika kuposa yake, ndipo idzadzivulaza yokha.
Ohms mu Oyankhula ndi Amplifiers
Ma amplifiers ndi ma speaker ambiri omwe mumawawona kuti agwiritsidwe ntchito ndi ogula, monga ma stereo akunyumba kapena zisudzo zakunyumba, amabwera mu ma ohm anayi, asanu ndi limodzi, kapena eyiti. Izi zati, nthawi zambiri mumawona ma ohm asanu ndi atatu akugwiritsidwa ntchito masiku ano.
Zolandila zambiri za stereo ndi A/V ndizokhazikika ndipo zimangopangidwa kuti zizigwiritsidwa ntchito ndi olankhula omwe ali ndi vuto lomwelo. Mudzakumana ndi zolandila, makamaka zodula kwambiri, zomwe zimakhazikika koma zimatha kupirira ma watts 100 pa ohm eyiti kapena, titi, ma watts 200 pa ma ohm anayi.
Ma amplifiers ena ali ndi chosinthira chomangidwira, nthawi zambiri kumbuyo, chomwe chimakulolani kusankha makonda osiyanasiyana a impedance. Izi zati, pomwe olandila A/V akupitiliza kuchulukitsa kuchuluka kwa ma tchanelo a makina owonera zisudzo kunyumba, tikuwona ocheperako ndi izi.
Olandila apamwamba kwambiri a A/V amatha kuthandizira olankhula ma-ohm anayi, koma sichinthu chomwe mungawone m'mitundu yotsika. Ngati simukutsimikiza ngati amplifier yanu imatha kunyamula ma ohm speaker anayi, onetsetsani kuti mumamatira ndi cholepheretsa chofananira, chomwe nthawi zambiri chimalembedwa kumbuyo kwa wolandila.
Ma audiophiles omwe amagwiritsa ntchito ma chubu amplifiers ayenera kusamala kwambiri ndi zoletsa, chifukwa machubu amplifiers amawonongeka mosavuta ndi zolakwika za impedance. Gwiritsani ntchito cholankhulira chokhala ndi cholepheretsa chochepa kwambiri ndipo mutha kuwononga wokamba nkhani, pomwe okamba omwe ali ndi vuto lalikulu amawononga amp.
Onetsetsani kuti mufanane
Monga tawonera kale, kusagwirizana kungathe kuwononga cholankhulira chanu kapena amp.
Ngati mukugwiritsa ntchito amplifier yolimba, yomwe magetsi ambiri ogula amagwiritsa ntchito, mutha kugwiritsa ntchito olankhula otetezeka omwe ali ndi kukana kwakukulu kuposa amp. Oyankhula asanu ndi atatu a ohm okhala ndi ma ohm anayi A/V olandila, mwachitsanzo, ayenera kugwira ntchito bwino.
Izi zati, pazotsatira zabwino kwambiri komanso osadandaula pang'ono zowononga chilichonse, kubetcha kwanu ndikuwonetsetsa kuti mukugwiritsa ntchito chokulitsa ndi okamba okhala ndi mavoti omwewo. Ngati mukuwerenga izi musanakhazikitse stereo kapena zisudzo zakunyumba, onetsetsani kuti mwayang'ana kalozera wathu wama waya anyumba.
