Ungasusa kanjani umsindo ocasulayo ohlelweni lwakho lokulalelwayo lwemoto
Uma umsindo ozwakalayo ovela kwi-stereo yakho yemoto ukhiphe izindlebe zakho, kungenzeka ukuthi i-loop yomhlabathi ingasolwa. Akunakwenzeka ukusho ngokuqinisekile ngaphandle kokubuka ukusethwa komsindo wakho wezimoto, kodwa uhlelo lwakho lwomsindo lungase lubhekane nenkinga yokudala yomhlabathi. Izingibe zomhlaba zenzeke lapho izingxenye ezimbili zisezindaweni ezinezindawo ezihlukahlukene zomhlabathi. Lokho kungakha i-current engadingeki, efaka uhlobo lokuphazamiseka okuvame ukuchazwa njengama-hum noma i-whine.
Indlela efanele yokulungisa inkinga yemoto yomsindo we-loop ukuhambisa konke endaweni efanayo. Uma ungeke ukwazi ukulungisa inkinga indlela efanele, isixazululo ukusebenzisa i-in-line sound filter.
I-Car Audio Ground Loops
Nakuba kunezinto eziningi ezingangenisa umsindo ongafuneki ohlelweni lokulalelwayo lwezimoto, izilophu zomhlabathi yizona ezimbi kakhulu. Le nkinga yomsindo ingenzeka noma nini lapho izingxenye ezimbili zomsindo ohlelweni olufanayo zisezindaweni ezahlukene. Uma lezo zindawo ezimbili zinezikhundla ezihlukene zomhlabathi, ukugeleza kwamanje okungafuneki, okungenza umsindo, kungeniswa ohlelweni. Uma umehluko kumathuba omhlaba ususwe, ukugeleza kwamanje okungadingeki kuphelile, futhi umsindo uhamba.
Ezikhathini zomsindo wekhaya, izitshalo zomhlabathi ziyakwenzeka lapho izingxenye ezimbili zixhunyiwe ezitolo ezahlukene. Ukuxazulula inkinga kungase kube yindaba elula yokushintsha lapho unezinto ezixhunyiwe khona. Ngeshwa, indaba yokumisa ingeyinkimbinkimbi encane kumasevisi alalelwayo wemoto. I-chassis - nanoma isiphi isimbi esithintana nayo - ingumhlabathi, kodwa akuzona zonke izizathu ezenziwe zilinganayo. Isibonelo, ukusekela ingxenye eyodwa yomsindo ku-chassis kanye nokukhanya okubhema ugwayi kuyisimo esidala esingabangela ekudaleni umhlabathi. Ukugxila i-head unit ku-cigarette lighter esikhundleni se-chassis nakho kungethula i-loop yomhlabathi.
Indlela efanele yokulungisa inkinga ukudiliza isistimu yakho yomsindo bese unamathisela izizathu ezingxenyeni ezinjengeyunithi yekhanda bese ukhulisa ngqo ku-chassis endaweni efanayo. Yingakho kubaluleke kakhulu ukuqiniseka ukuthi konke kuhlelwe ngokucophelela ngesikhathi sokuhlela kwanoma yisiphi isimiso esisha somsindo wezithuthi bese sibheke kahle ngesikhathi sokufakwa. Lesi yisimo lapho kutholakala khona isisindo sokuvimbela isisindo semithi.
Ukususa i-Ground Loops
Ngenkathi indlela enhle yokulungisa i-loop yomhlaba ukubhekana nekhanda ngokuhlukile phakathi kwamandla emkhatsini wezingxenye ezahlukene, akuyona indlela kuphela. Uma umcabango wokudiliza isistimu yakho yomsindo, ukuthola izizathu, bese ubeka konke emuva ndawonye akuzwisi okukhangayo, khona-ke ungase ufune ukubheka i-isolator.
I-ground loop isolators iqukethe i-input, i-output, ne-transformer. Isignali yomsindo ingena ku-isolator ngokusebenzisa i-jack yokufaka, idlula ku-transformer, iphinde iphume nge-plug yokukhipha. Njengoba kungekho ukuxhumana okuqondile kagesi emkhatsini wokufakwayo nokukhipha, umthamo womhlabathi kanye nanoma yikuphi ukuphazamiseka okwenzayo kuhlukaniswe nesignali.
Ngenkathi lezi zihlungi zomsindo ziyi-patches kuphela, futhi inkinga yakho engaphansi ikhona, i-patches exazulula inkinga ngokushesha.
