Ntau lub neej ntsib peb nrog kev xaiv nyuaj. Peb yuav tsum nrhiav ib co gadget. Nyob rau tib lub sijhawm, nws yuav tsum pheej yig, zoo tshaj plaws thiab flawless. Lawm, peb to taub tias qhov no yog xyaum ua tsis tau. Yog li ntawd, peb yuav tsum xaiv raws li cov txheej txheem uas haum rau peb, thiab tseem yuav txi ib yam dab tsi. Hnub no peb yuav sim xaiv DAC zoo.
Qhov no yog dab tsi?
Ua ntej yuav hais txog qee cov qauv ntawm cov cuab yeej no, nws tsim nyog piav qhia nws yog dab tsi, rau cov neeg tsis paub. Lub digital-rau-analog converter yog tsim los ua cov lej digital rau hauv cov teeb liab analog. Yog li, cov cuab yeej tuaj yeem suav tau tias yog ib hom "tus coj" los ntawm ib lub ntiaj teb - digital, mus rau lwm qhov - analog.
Cov cuab yeej no kuj muaj "antagonist". Nws ua tib yam nkaus, tab sis rov qab. Feem ntau, lub suab converter ua haujlwm ntawm lub hauv paus ntsiab lus uas yuav tsum ua haujlwm, nws yuav tsum tau txais cov teeb liab digital, uas yog raws li kev hloov pauv ntawm mem tes code. Yog hais tias peb muaj ib tug compressed hom, ua hauj lwm nrog nws yog siv codecs.
Destination
Tau kawg, txhawm rau yuav DAC zoo, koj xav tau qhov laj thawj zoo rau qhov no. Hardlytus neeg siv zoo tib yam yuav siv nyiaj ntawm cov khoom siv zoo li no. Feem ntau, ib lub gadget xav tau rau cov neeg uas xav hloov cov teeb liab los ntawm digital "world" mus rau analog. Ua piv txwv, nws yog siv hauv CD player.
Kev faib tawm
Nyob ntawm lub hom phiaj, nws muaj peev xwm faib DACs rau hauv pab pawg. Qhov yooj yim tshaj plaws yog mem tes dav. Feem ntau pom nyob rau hauv Hi-Fi li los yog qhov chaw koj yuav tsum tau tswj fais fab motors. Hom kev ua haujlwm no yog ua raws li lub tsheb ciav hlau pulse uas dhau los ntawm cov lim dej qis. Yuav kom tau txais nws, koj yuav tsum tau tos kom txog thaum lub hloov pauv digital code yog proportional rau lub sijhawm uas qhov chaw ruaj khov tam sim no ua haujlwm.
Tom ntej no peb ntsib resampling. Nws yog nyob ntawm qhov hloov pauv ntawm tus nqi mem tes ceev. Hom no yog npaj rau kev ua haujlwm kom raug ntawm cov khoom siv uas muaj peev xwm qis dua nrog cov cuab yeej muaj peev xwm ntau dua. Nws ntseeg hais tias xws li DAC yog pom nyob rau hauv ib-ntsis qauv. Yog li, raws li cov thev naus laus zis no, muaj kev sib pauv ntawm impulses nrog cov lus tsis zoo.
Hom kev hnyav xav tias tus nqi ntawm qhov tam sim no yuav sib npaug rau qhov hnyav ntawm me ntsis. Cov khoom tsis yog xoom hauv qhov no tuaj yeem suav tau. Cov ntaiv tau txais ib lub voj voog tshwj xeeb, uas muaj ntau lub resistors, muaj ob hom kev suav nrog.
Ntse
Xaiv qhov zoo tshaj plaws DAC, koj yuav tsum nkag siab nws cov yam ntxwv. Yog li, nws yog ib qho tsim nyog yuav tsum tau hais txog ob peb qhov kev txwv yooj yim. Nws yog ib qho tseem ceeb kom nkag siab lub ntsiab lus ntawm qhov tob me ntsis,Qhov siab tshaj qhov piv txwv, monotonicity, dynamic ntau yam, zoo li qub thiab zaus teb. Yog li nws muaj peev xwm txiav txim siab qhov xav tau qib tso zis, zaus ntawm kev ua haujlwm ruaj khov, lub peev xwm ntawm cov cuab yeej los ua kom cov teeb liab tso tawm analog.
Rating
Ranking the best DACs is not easy. Muaj ntau ntau, lawv txhua tus txawv. Qee qhov txawv ntawm cov yam ntxwv sab nraud, lwm tus los ntawm kev siv tshuab. Qee tus tau nruab nrog ntau cov thev naus laus zis thiab kev ua haujlwm, lwm tus yog tsom rau cov haujlwm tshwj xeeb. Yog li ntawd, ua ib daim ntawv teev npe thiab xa txhua tus qauv mus rau ib qho chaw tshwj xeeb yog ib txoj haujlwm ua tsaug. Yog li ntawd, hauv kev txiav txim pub dawb, peb yuav xav txog ob peb tus qauv ntawm Matrix, Meridian Audio, Esoteric thiab lwm yam.
Ntau yam
Xaiv DAC zoo tsis yog teeb meem. Muaj ntau ntau yam kev xaiv transducer ntawm kev ua lag luam uas tuaj yeem haum koj ntawm cov xim, cov duab thiab qhov loj me, nrog rau cov yam ntxwv ntawm kev ua haujlwm.
Matrix Mini-I Pro yog tsim los ntawm lub tuam txhab Suav. Ntau tus kws tshaj lij ntseeg tias cov chaw tsim khoom tam sim no tau tshwm sim hauv kev ua lag luam thiab ib txwm tsim lub resonance uas, txawm hais tias nws tsis ntshai cov neeg sib tw, ua rau lawv ua haujlwm nyuaj. Lub tuam txhab muaj kev xaiv loj ntawm cov khoom siv thiab cov khoom siv suab. Ntxiv mus, ntawm cov qauv muaj ob qho kev xaiv nyiaj txiag rau $ 200 thiab kev xaiv kim rau $ 1000.

Yog tias koj tsis nkag mus rau hauv cov khoom siv digital, ces qhov taw qhia tiag tiag ntawm DAC zoo yog lub suab. Hauv qhov no, cov neeg siv sau tseg purity, zoo daws teeb meem, du thiab lingering siab zaus. Nthuav lub suab nrov zoo nrog lub suab sib npaug.
Cov neeg yuav khoom tau sau tseg ntawm cov yam ntxwv ua haujlwm nrawm ntawm DAC, qhov tsis muaj "roundness", siab bass thiab hyperbolic suab xim. Cov suab paj nruag tsis muaj qhov ntxhib lossis ntxhib, thiab cov zaus tau pom thiab huv.
Suab
Esoteric D-07X yog DAC zoo uas ntau tus yuav pom kim heev - txog 6 txhiab nyiaj. Tab sis connoisseurs nkag siab tias vim li cas tus nqi zoo li no rau cov khoom siv compact. Qhov no version muaj ib tug zoo zoo rooj plaub, ib tug loj xaiv ntawm functions thiab hom, thiab qhov tseem ceeb tshaj plaws - lub suab zoo heev. Ib qho qauv zoo sib xws uas tau tshwm sim ua ntej me ntsis muaj teeb meem nrog USB receiver.
Qhov tshiab zoo li tau ploj qhov kab no. Nws tau nruab nrog kev txhais cov ntaub ntawv, lub peev xwm los tua cov lim digital thiab lub mloog pob ntseg tshiab. Kuj tseem muaj kev tswj hwm qhov ntim ywj pheej. Txawm hais tias muaj ntau qhov kev tsim kho tshiab, lawv muaj kev cuam tshuam me ntsis ntawm kev nce nqi.
Tau kawg, koj tuaj yeem pom zoo qee qhov-Tom qab ntawd qee qhov kev teeb tsa thiab kev hloov kho ntawm cov cuab yeej siv, tab sis, feem ntau yuav yog, nws yuav yog qhov tseeb dua rau tus tswv ntawm nws tus kheej nrog txhua txoj haujlwm txhawm rau txhawm rau teeb tsa cov qauv uas zoo rau lawv tus kheej.

Ua tsaug rau lawv, nws tau dhau los ua kev sib koom ua ke nrog cov cuab yeej siv los ntawm lwm cov tuam ntxhab. Peb tau sau tseg tias muaj peb lub lim dej ntau dhau, uas feem ntau siv ntawm zaus ntawm 44kHz thiab 48kHz.
Cov Lus Qhia
Nws nyuaj rau xaiv qhov zoo sab nraud DAC. Qhov no yuav tsum tau ua nrog. Yog tias koj xav tau nws rau kev ua haujlwm, feem ntau koj twb paub txog qee cov qauv thiab cov chaw tsim khoom, thiab nws yooj yim dua rau koj xaiv. Yog tias, ntawm qhov tsis sib xws, koj tau txiav txim siab yuav DAC thawj zaug, tom qab ntawd koj yuav tsum nkag siab rau lub hom phiaj twg koj xaiv cov cuab yeej, qhov koj xav tau los ntawm nws. Ntawm chav kawm, nws yog ib qho tsim nyog los kawm cov kev txheeb xyuas, txij li cov yam ntxwv tsis yog ib txwm sib haum mus rau qhov tseeb, lossis qhov tseeb lawv tig mus rau qhov tseeb. Zoo, koj tsis tuaj yeem "yuam" ntawm tus qauv zoo nkauj. Yog hais tias koj muaj ib tug zoo tsim nyob rau hauv pem hauv ntej ntawm koj, qhov no tsis txhais hais tias lub suab ntawm koj tag nrhotxaus siab.
