Saib xyuas cov kab kev ua yuam kev yooj yim uas ua rau cov neeg hais lus tawm ntawm theem
Siv ib tug neeg hais lus rau ib tus neeg txais lub suab nrov los yog siv cov lus qhia yooj yim xws li tus txheej txheem qhia yooj yim-thiab rau feem ntau, nws yog. Tab sis koj yuav tsum paub txog qee cov ntsiab lus tseem ceeb los xyuas kom tau qhov zoo tshaj plaws. Piv txwv, kev hloov kev polarity yog ib qho yooj yim tab sis ntau qhov yuam kev uas tuaj yeem txo koj lub suab.
Lus Tawm Terminals
Feem ntau txhua tus neeg txais suab nrov, cov neeg hais lus, thiab cov neeg hais lus (piv txwv, cov uas tau txais cov teeb meem los ntawm cov xov tooj sib txuas xov tooj) feature terminals nyob rau nraum qab rau kev hais lus txuas xov tooj. Cov terminals no yog lub caij nplooj ntoos hlav lub caij nplooj ntoos hlav los yog kev sib tw hom.
Cov terminals no kuj yuav luag txhua zaus xim-cim rau kev qhia yooj yim: Lub dav hlau zoo (+) yog feem ntau liab, thaum lub dav hlau tsis zoo (-) yog feem ntau dub. Nco ntsoov hais tias qee cov neeg tham yog bi-wire muaj peev xwm , uas txhais tau hais tias cov khoom siv liab thiab dub tuaj nrog ua ke rau tag nrho plaub txoj kev sib txuas.
Hais lus hlau
Cov lus qhia yooj yim tshaj plaws-tsis yog RCA lossis Optical / TOSLINK zoo-muaj ob qhov chaw los nrog txhua kawg, zoo (+) thiab tsis pom (-). Yooj yim, tab sis tseem tshuav 50-50 txoj kev tau txais cov kev txuas no tsis yog tias koj tsis ceevfaj. Obviously, qhov no yog qhov zoo tshaj plaws zam, vim hais tias swapping qhov zoo thiab tsis pom muaj peev xwm ua rau cuam tshuam kev ua haujlwm. Nws yog tsim nyog rau lub sijhawm kom ob npaug xyuas tias cov xov hlau no raug khi txuas nrog ua ntej zog thiab ntsuas cov neeg hais lus.
Thaum cov khoom qis tom qab ntawm cov cuab yeej siv sab nraud yuav pom tau yooj yim, tib yam tsis tau hais rau cov lus sib tham. Qhov no feem ntau yog qhov teeb meem tshwm sim tuaj yeem vim tias daim ntawv qhia no tsis yog tas li.
Yog hais tias tus neeg hais lus hlau tsis muaj ob lub suab paj nruag, nrhiav ib lub stripe los yog cov kab dashed (cov no feem ntau qhia tau qhov kawg ntawm kev sib tw) raws ib qho ntawm cov sab. Yog hais tias koj lub xaim muaj lub rwb thaiv kab xim, qhov stripe lossis tsoo ntse yuav tsaus ntuj. Yog hais tias rwb thaiv tsev yog xim tsaus, lub stripe los yog lub tsoo puav pheej yuav yog xim dawb.
Yog hais tias tus neeg hais lus xaim yog meej los yog txhais kom pom, kos rau cov cim sau tseg. Koj yuav tsum pom cov cim (+) lossis (-) thiab (thiab qee zaus ntawv) los qhia txog kev khov kho. Yog tias qhov ntawv lo no tsis yooj yim nyeem los yog txheeb xyuas, siv daim kab xev rau tom tagnrho tom qab koj paub tias nws yog leejtwg sai dua. Yog tias koj tsis paub meej thiab xav tau ob-kos (tshwj xeeb tshaj yog tias koj muaj cov kab sib qeeb ntawm cov xov hlau), koj tuaj yeem kuaj cov lus txuas xov tooj nrog kev siv AA los yog AAA roj teeb.
Hom Kev Sib Txuas
Cov lus tshaj tawm xov xwm feem ntau pom tau tias yog liab qab, txhais hais tias koj yuav siv ib txoj hlua khi rau kom pom cov hlua ntawm qhov xaus. Nws yog qhov zoo rau txoj hlua khi hlua khi kom nruj nrawm kom lawv nyob ua ke raws li ib txoj hlua zoo nkaus xwb, tsis muaj teeb meem yog tias koj cov khoom siv caij nplooj ntoos hlav los yog khi ntawv tso tawm.
Koj tseem tuaj yeem nrhiav cov lus qhia xaim nrog nws tus kheej txuas nrog, uas tuaj yeem ua kom sib txuas sib txuas nrog rau cov kev pab sai sai kom paub tias lawv yog xim-coded. Ntxiv mus, koj tuaj yeem nruab koj tus kheej txuas yog tias koj tsis nyiam mus fumble ib ncig nrog cov ntawv nyeem. Lawv tuaj yeem tau muas nyias mus nce cov lus qhia ntawm koj cov lus qhia cables.
Tus pin connectors tsuas siv nrog lub caij nplooj ntoo hlav qis. Cov koob no muaj ruaj khov thiab yoojyim rau.
Banana plug thiab spade connectors tsuas yog siv los ntawm khi khoom. Cov txiv tsawb plug ntsaws ncaj nraim rau qhov txuas ntawm qhov chaw, thaum lub qhov chaw txuas khov nyob ruaj khov rau hauv qhov chaw thaum koj nrawm qis hauv qhov chaw.
Txuas Txais Cov Txais lossis Cov Nuj Nqis
Cov xov hlau yuav tsum sib txuas kom raug rau ntawm tus neeg tuaj yeem lossis lub zog thiab cov neeg sib tham. Tus neeg hais lus zoo (xim liab) hauv lub receiver lossis amplifier yuav tsum tau txuas nrog lub qhov kev sib tham ntawm cov neeg hais lus, thiab tib yam siv rau cov kev phem terminals rau tag nrho cov khoom siv. Technically, cov xim lossis daim ntawv lo ntawm cov xov hlau tsis tseem ceeb npaum li ntev tau tag nrho cov terminals match. Txawm li cas los xij, nws yog qhov zoo tshaj plaws kom ua raws li cov kev ntsuas kom tsis txhob muaj kev kub ntxhov tom qab.
Thaum twg ua tiav lawm, cov neeg hais lus tau hais tias "nyob rau hauv theem," uas txhais tau hais tias ob leeg hais lus ua haujlwm tib yam nkaus. Yog hais tias ib qho ntawm cov kev sib txuas no tsis muaj kev sib thim (piv txwv li, qhov zoo rau qhov tsis zoo), ces tus neeg hais lus raug suav hais tias "tsis muaj theem." Qhov teeb meem no ua rau muaj teeb meem loj suab nrov zoo. Nws yuav tsis ua puas rau tej yam khoom, tab sis koj yuav hnov suab sib txawv. Piv txwv yog:
- Ntshav, lean-sounding bass , pluag subwoofer kev ua tau zoo , los yog ob qho tib si
- Tsis muaj qhov duab pom qhov tsis zoo
- Ib qho kev txiav txim siab zoo hais tias lub system tsuas yog tsis muaj suab cai
Qhov tseeb, lwm yam teeb meem tuaj yeem tsim teeb meem zoo li suab, tab sis cov lus qhia tsis yog lub ncauj lus yog ib qho yuam kev tshaj plaws thaum tsim teeb tsa lub tso suab. Qhov no tuaj yeem ua tsis yooj yim, tshwj xeeb tshaj yog tias koj muaj kev sib tham nrog cov kwj ntawm lub suab thiab video cables.
Li ntawd, siv koj lub sij hawm los xyuas kom tseeb tias txhua tus neeg hais lus nyob hauv-theem: zoo-rau-zoo (liab-rau-liab) thiab tsis zoo-rau-tsis pom (dub-rau-dub).
