- Tam sim no cov khoom siv-chain siab txhais tau hais tias cov cuab yeej tshiab ntxiv rau qhov ntim xaj tuaj yeem ncav cuag qhov rais dhau 40 lub lis piam.
- Taw qhia
Yog tias koj tsim lossis tsim cov khoom siv audio-visual, koj yuav ua haujlwm nrog RCA jacks sai dua lossis tom qab. Lawv zaum ntawm turntables, set-top boxes, guitar pedals, thiab txawm xeem iav. Kab lus no teb cov lus nug "Dab tsi yog RCA jacks"thaum muab cov pab pawg engineering paub meej lawv xav tau kev kos duab, BOMs, thiab kev yuav khoom.
- RCA Jacks yog dab tsi?
Ib RCA jackyog poj niam ib nrab ntawm ob feem, tsis sib npaug coaxial connector system. Lub jack's center socket nqa teeb liab thaum lub plhaub khi rau hauv av. Cov txiv neej ib nrab-hu ua RCA plug-cov phooj ywg los ntawm kev sib txhuam. Variants tshwm nyob rau hauv cov npe xws li phono connector, cinch connector, los yog yooj yim A/V jack.
Vim tias tus qauv tsim yog qhov yooj yim, tus nqi qis, thiab me me, nws tseem muaj nyob hauv cov neeg siv khoom. Ib qho RCA jack ntawm PCB feem ntau ua raws li lub qhov hneev taw, txawm hais tias qhov chaw-mount muaj nyob rau cov kab khiav ceev.
