Alas, txhua txhua xyoo yuav ntau thiab ntau hais tias tus tswv ntawm lub computers ntawm lo lus "kev xaiv ntawm daim card suab" yog heev tsis muaj dab tsi, "lawv hais tias." Thiab tag nrho vim hais cov neeg muaj tsis muaj dab tsi los sib piv, thiaj li muaj ntau txaus siab rau yam uas peb muaj, tej zaum kuj txawm piv txwv tias yog tias nws yuav ua tau lwm yam. Piv txwv li, yog tias koj saib nyob rau ntawm qhov forums rau cov kev xaiv ntawm LCD saib, thaum lub heev heev ceg tshwm sim nrog loj sib cav tswv yim hais txog cov pros thiab cons ntawm ib tug matrix. Feem ntau, "cem" cov nyiaj txiag TN, muab piv nws nrog rau VA, IPS thiab lwm yam derivatives thereof. Qhov no yog vim hais tias cov neeg muaj ib yam dab tsi los sib piv. Tab sis lub suab card rau ua si suab paj nruag yog ntau npaum li cas yooj yim, vim hais tias txawm ib tug yooj yim discrete qauv zoo heev tshaj cov yam ntxwv ntawm feem ntau ntawm cov built-txiav txim siab raws li nyob rau hauv suab codecs rau HD Audio thiab AC97. Vim li no, muaj ib tug paradoxical teeb meem nyob qhov twg nws yog tsis yooj yim sua xaiv ib tug me ntsis zuj zus los yog ib tug me ntsis zoo dua. Ib tug ob peb xyoo dhau los, cov kev xaiv ntawm daim card suab yog tsis yooj yim raws li nws tej zaum yuav zoo li. Yog li ntawd, kuv tau mus rau nrog, piv txwv li, yuav ib tug tiag tiag 16-ntsis suab Blaster los ntawm Creative los yog Vortex los ntawm Aureal txhawb pheej technology surround suab. Tam sim no, ntau tau hloov - muaj cov tshiab producers, lwm leej lwm tus zoo los yog tau absorbed, phaib tau txais lub sij hawm uas lawv predecessors txawm "yeej tsis ua npau suav txog."
Xaiv lub suab card pib nrog xaiv cov lub interface (piv txwv tias yog discrete qauv). Ob peb ntawm lawv - yog maj muab tshem tawm los ntawm lub PCI ntau lawm, tus tshiab PCI-Express, cov sab nraud USB thiab FireWire. qhov zoo tshaj plaws kev xaiv yuav tsum yog ib tug qauv uas muaj ib PCI-Express rau lub PC. Cov bandwidth ntawm no bus yog txaus rau tej suab ntws. Tab sis cov kev xaiv ntawm ib tug sab nraud daim card suab yog nthuav, ua ntej ntawm tag nrho cov, tus tswv ntawm laptops. Txawm tias USB yog ntau ntau yam tshaj FireWire, nws yuav ua tau qhov kev ncua, li ntawd, yog tias koj npaj mus koom tiag nyob rau hauv cov suab paj nruag, siv ib tug mobile computer, cov kev xaiv no yog me me - tsuas yog IE-1394 (FireWire lwm lub npe).
Xaiv lub suab card yog tej zaum ua raws li nyob rau hauv me ntsis tob converter suab-digital (ADC) - tus nqi yog siab dua, qhov zoo dua. Nyob rau hauv dav dav, lub kauj yog muaj tseeb. Tiam sis nco rau hauv siab hais tias tej zaum lub suab zoo yog cuam tshuam los ntawm lwm yam kev xaiv.
Nws yog ib heev ntshaw kom txhawb ob-txoj kev kis tau tus mob (Full dulpex), thaum lub sij hawm uas koj tau sau thiab playback ib txhij. Tshwj xeeb tshaj yog yuav tsum xyuam xim rau no thaum xaiv cov card nrog ib tug USB interface laus versions (1.1).
Cov tom ntej no tseem ceeb heev parameter - cov inputs / outputs. Peb lub tso suab lawv tej cards tsawg tshaj li hais tias ntawm lub multi-channel analog. Tag nrho cov ntawm lawv yog muab faib ua ob pawg - yam thiab asymmetric. Feem ntau, qhov no yog qhia nyob rau hauv cov kev specification. Tus thawj yog tsawg pawg los ntawm ntau yam teeb.
Cov outputs SPDIF - ib tug "hu card" tej yam ntaus ntawv. Nws tso cai rau koj mus digitally kis suab mus rau lwm yam ntaus ntawv tsis muaj distortion. Lub cev SPDIF connector yuav zoo sib txawv: Fiber (optics) thiab lub classic "tulip". Qhov txawv tsuas yog tus kis tau tus mob nruab nrab, yog li ntawd thaum xaiv ib tug yuav tsum tau mus tsom rau cov khoom, uas yuav tsum tau kev cob cog rua rau lub suab card.
Rau musicians, nws yuav ua rau kev txiav txim zoo mus saib nyob rau hauv lub qhov zoo kev ua qauv, vim hais tias qhov kev ncua, suab nrov thiab lwm yam "charms" ntawm cov nyiaj txiag kev txiav txim siab yuav nullify tag nrho lub dag zog. Tab sis rau tsev neeg siv mus nrhiav kom tau ib tug zoo suab, haum discrete qauv ntawm nruab nrab-kev ua lag luam los ntawm ASUS los yog tswv yim.
