Yog tias koj tau txuas lub CD lossis DVD player rau koj lub TV, koj yuav tau siv RCA cable. Ib qho yooj yim RCA cables muaj peb cov xim-coded plugs txuas los ntawm ib kawg uas txuas mus rau peb cov xim sib xws nyob rau sab nraum qab ntawm TV, projector, lossis lwm cov khoom tso tawm. Nws nqa cov suab thiab video teeb liab los ntawm cov khoom siv sib txuas mus rau cov khoom tso tawm (piv txwv li TV lossis hais lus).
RCA cable yog lub npe rau Xov tooj cua Corporation ntawm America, uas thawj zaug siv nws nyob rau hauv 1940s los txuas phonographs rau amplifiers. Nws nkag mus siv hauv tsev nrov hauv '50s thiab tseem siv niaj hnub no. Ob hom ntau tshaj plaws yog cov yeeb yaj kiab thiab cov khoom sib xyaw.
Composite Video RCA Cables
Cov xim siv hauv cov kab sib txuas RCA feem ntau yog xim liab thiab dawb lossis dub rau sab xis thiab sab laug suab thiab daj rau cov yeeb yaj kiab sib xyaw. Composite video yog analog, lossis tsis yog digital, thiab nqa tag nrho cov ntaub ntawv video hauv ib lub teeb liab. Vim hais tias cov yeeb yaj kiab analog tau tsim los ntawm peb qhov kev sib cais pib nrog, nyem rau hauv ib lub teeb liab txo qhov zoo me ntsis.
Composite video signals feem ntau muaj 480i NTSC/576i PAL tus qauv txhais cov teeb liab. Nws tsis yog tsim los siv rau high-txhais analog lossis digital video signals.
Component Cables
Cov kab hluav taws xob muaj ntau dua thiab qee zaum siv hauv HD TVs. Cov kab hluav taws xob muaj peb kab yeeb yaj kiab feem ntau xim liab, ntsuab, thiab xiav thiab ob kab suab xim liab thiab dawb lossis dub. Ob kab liab feem ntau muaj xim ntxiv ntxiv kom paub qhov txawv.
Cov RCA cables muaj peev xwm ua kom muaj kev daws teeb meem ntau dua li cov kab sib txuas video: 480p, 576p, 720p, 1080p, thiab ntau dua.
Siv rau RCA Cables
Txawm hais tias HDMI cable yog txoj hauv kev niaj hnub txuas rau cov khoom siv, tseem muaj ntau txoj hauv kev los siv RCA cables.
Lawv tuaj yeem siv los txuas ntau yam khoom siv suab thiab video, xws li camcorders, TVs lossis stereos rau cov neeg hais lus. Feem ntau cov camcorders high-end muaj tag nrho peb RCA jacks, yog li lub teeb liab nkag los yog tawm hauv lub cuab yeej mus los ntawm peb txoj kev sib cais-ib qho video thiab ob lub suab-ua rau muaj kev hloov pauv zoo. Cov koob yees duab qis-kawg feem ntau tsuas muaj ib lub nkaus xwb, hu ua lub tso suab tso suab, uas sib txuas tag nrho peb cov channel. Qhov no ua rau kev hloov pauv tsis zoo vim tias lub teeb liab raug compressed. Nyob rau hauv ob qho tib si, RCA cables kis analog, lossis tsis yog digital, cov cim. Vim li no, lawv tsis tuaj yeem txuas ncaj qha rau hauv lub computer lossis lwm yam khoom siv digital. RCA cables txuas amplifiers rau txhua yam khoom siv.
Quality of RCA Cables
Ntau yam cuam tshuam rau qhov zoo, tus nqi, thiab kev ua haujlwm ntawm RCA cables:
- Cov Khoom: Cov khoom txuas ntawm RCA cables feem ntau yog kub, nyiaj, lossis tooj liab. Raws li koj xav tau, cov khoom sib txuas kub yog qhov kim tshaj plaws. Lawv kuj zoo dua li cov nyiaj thiab tooj liab txuas ntawm kev tiv thaiv oxidation, tab sis tsis zoo ntawm hluav taws xob conductivity. Cov nyiaj sib txuas yog qhov zoo tshaj plaws rau cov hluav taws xob conductivity nrog tooj liab cables los nyob rau hauv ib tug ze thib ob thiab cov kub cables ntog deb tom qab. Lwm cov ntaub ntawv tsim nyog yog npib tsib xee, zinc, thiab tin.
- Cable Length: Cable ntev muaj qhov tsis zoo rau cov teeb liab zoo. Yuav ib lub cable uas tsuas yog ntev npaum li koj xav tau los ua kev sib txuas rau qhov zoo tshaj plaws teeb liab zoo.
- Shielding: Ib txoj hlua tiv thaiv zoo muab lub teeb liab zoo dua li qhov uas tsis muaj kev tiv thaiv zoo.
- Lwm kawg ntawm cable: Yog tias ua tau, phim cov khoom siv nyob rau lwm qhov kawg ntawm cable rau cov khoom siv hauv cov khoom sib txuas. Tsis txhob sib phim tin nrog kub lossis nyiaj nrog kub. Cov kev sib xyaw ua ke tuaj yeem ua rau muaj teeb meem vim muaj cov tshuaj tiv thaiv electrolytic.
Cov lus nug nquag
- Koj txuas HDMI cov zis rau RCA cov tswv yim li cas? Koj tuaj yeem siv HDMI rau AV / RCA Converter. Txuas lub converter mus rau lub hwj chim, ces txuas lub HDMI cable, thiab liab thiab dawb RCA cables, mus rau lub converter. Txuas lub converter mus rau TV lossis lwm yam khoom siv, thiab tom qab ntawd txuas cov kab daj video los ntawm lub converter rau koj lub cuab yeej.
- RCA cov zis qis yog dab tsi? Cov suab qis qis feem ntau yog plaub volts lossis qis dua thiab muab faib ua cov teeb liab tsis muaj zog kis tau los ntawm RCA cables. Qib qis kuj tseem hu ua kab-theem nkag nkag.
