Maola awiri ndi Kusintha Kwambiri Kumatha Kupeza Audio Yambiri Yomwe Mukufuna
Ngati mukuyang'ana stereo amplifier / receiver yanu, mungazindikire kuti imapanga kusinthana kokhazikika kuti musinthe ma seti oyankhula A ndi B. Njirayi ikulolani kuti muzigwirizanitsa okamba awiri, makamaka kuchokera ku chipinda chosiyana. Oyankhulawo ayika ku Kusintha kwa A kungakhale kotanthawuza pa TV yaikulu kapena zosangalatsa za mafilimu, pamene okamba atayika ku kusintha kwa B akhoza kukhazikitsidwa kwa kumvetsera nyimbo. Kawirikawiri, wolandirayo akhoza kugwira bwinobwino maselo onsewo panthawi imodzimodziyo. Ena olandila amakhalanso ndi zipinda zamakono zothandizira okamba m'magulu ambiri kapena zipinda zina m'nyumba mwanu, ngakhale kuti palibe malo onse omwe angathe kusewera panthawi yomweyo.
Pogwiritsa ntchito Wosankha Wowankhula
Koma bwanji ngati mukufuna kugwirizanitsa zambiri, magulu osiyana a okamba ndi waya zipinda zina? Njira yosavuta komanso yotetezeka-yomwe nthawi zambiri imakhala yopindulitsa pazinthu za bajeti-ingakhale yogwiritsa ntchito wosankhidwa wosankha. Zimakhala ngati chikhomo kapena kupatukana, kulola ogwiritsa ntchito kugwirizanitsa ndi mphamvu ochuluka ngati anayi, asanu ndi asanu, kapena asanu ndi awiri a okamba kwa wolandira mmodzi kapena amplifier. Zitsanzo zina zimaperekanso mphamvu yoyendetsera voliyumu pa oyankhula awiri. Kwa nthawi yokha ndi mtengo wa waya kuti ukhalepo ndikugwirizanitsa okamba onse, mukhoza kudzipanga wokhazikika bwino ndi mwayi wosintha kapena kukweza okamba.
Osati kokha kusinthana kumagwira oyankhula ambiri, koma ndikofunikira kuti ateteze wamapukutu kapena wolandila kuwonongeka. Matenda otsika kwa mpweya sangayambitse chifukwa chosewera maulendo ambiri nthawi imodzi. Chifukwa chiyani? Amplifiers ndi ovomerezeka kawirikawiri amawerengedwa kwa oyankhula omwe ali ndi 8 ohms of impedance (ena amavomereza pakati pa 4 ndi 8 ohms, koma 8 amayamba kukhala achizolowezi). Mndandanda wa mpikisano ndi wofunikira chifukwa umatsimikizira momwe magetsi amathawira kwa okamba, ndipo kugwirizanitsa maselo ambiri a okamba kumawonjezera kuchuluka kwa zomwe zilipo panopo. Mwachitsanzo, ngati awiri awiri a o-ohm okamba akugwirizana ndi kusewera, vutoli ndi 4 ohms. Mawiri atatuwa amapezeka mu 2 ohms of impedance, ndi zina zotero. Ngati kuthamanga kwamakono kumawonjezereka kwambiri, kumatha kupitirira mphamvu ya wolandila. Chotsatiracho chingapangitse wolandirayo kuti ayambe kuteteza chitetezo chake ndi kutseka kwa kanthawi, zomwe zingayambitse nthawi yowonjezereka kwa wowonjezera. Zosakhala bwino.
Choncho yankho labwino ndilo kugwiritsa ntchito chosinthana cha osankhidwa omwe amawonetsanso zosayenera. Mwanjira iyi, mutha kusewera momasuka nthawi zambiri, osachepera sikisi, kapena asanu ndi atatu oyankhula palimodzi pokhapokha mutakhala ndi mpweya wabwino wa 8 ohms, motero muteteze amplifier ndi wolandila. Kuti mugwiritse ntchito chosinthana cha osankhidwa, mungagwirizane ndi zotsatira zachitsulo ndi zolondola za amplifier / receiver mpaka muzolowera za kusintha. Kenaka yongani kulumikiza wokamba nkhani osiyanasiyana kumalo okamba nkhani, ndipo ndizo! Malingana ndi mitundu ya okamba nkhani omwe muli nawo komanso komwe mukukonzekera kuziyika, zingatenge maola ochepa kuti muthamangitse mawaya oyankhula ku zipinda zina m'nyumba mwanu. Musaiwale kuyang'ana ndondomeko ya waya pampikisano wosankha wosinthana choyamba, kuti muwonetsetse kuti zimagwirizanitsa (pafupifupi 14 mpaka 18 gauge) ndi mawaya oyankhula omwe mukukonzekera kugwiritsa ntchito.
Komanso kumbukirani kuti mumvetsere momwe okamba anu amalumikizira (mwachitsanzo, mapegi a banki, magulu opangira mapepala, zowumikiza pini ) kuti muthe kusankha mtundu woyenera wosankha. Kumbukirani kuti voliyumu ya amplifier / receiver idzakhudza okamba onse, ndipo wokamba nkhaniyo amasintha kapena sangakhale ndi maulamuliro osiyana. Choncho, mukhonza kulingalira kuti muyambe kukhazikitsa gawo loyendetsa voliyumu pakati pa wokamba nkhani aliyense ndi wosintha. Pamafunika nthawi yochulukirapo, koma kumbaliyi ndi kuti zipinda zidzasintha maulamuliro ake. Ndipo ngati wokamba nkhani wosankhidwa alibe malemba ake m'malo (ambiri amachititsa), mukhoza kupanga malemba anu ndi kuwasunga pamwamba ndi pansi pamsinkhu uliwonse.
