Ukuphuculwa kweNtsebenzo yomsindo nge-Outboard DAC
Ehlabathini lomsindo wedijithali, umdlalo wokugqibela ngumguquleli wangaphandle we-digital-to-analog , okanye i-DAC. Ezi ncinane ezincinci ezingabonakaliyo ziyakhiwa kwidiski yediski okanye ikhomputha kwaye zizitshixo zokuguqula ngokuchanekileyo izigidigidi ze-0s kunye ne-1 zesignali yomsindo we-digital (umz. Ukusuka kwi-CD okanye i-DVD) kwiimpawu zendalo ze-analog ezithembekileyo isandi sokuqala.
I-DAC yintloko yomsindo wedijithali. Ukuphucula ngokukhawuleza kwezobugcisa kunye nokunyuka kwindalo yeselula / yekhompyutheni iye yaqhuba imfuneko ye-DAC zangaphandle. Ezi zixhobo zenzelwe ukuphucula ukusebenza komsindo kwabadlali be-disc, iikhomputha, izixhobo zemidlalo kunye nezinye izixhobo zomsindo we-digital .
Cambridge Audio DacMagic
I-DacMagic 100 yinkampu yokupakisha ngaphandle kweDAC enikezwa nguCambridge Audio, umenzi wase-UK. Ukususela ngo-1968, i-Cambridge Audio inikezele kwizinto eziphambili ze-AV, izixhobo kunye neenkqubo ezincinane. I-DacMagic 100 yincinci encinci, ukulinganisa malunga ne-1/3 ubungakanani bomkeli ophakathi okanye i-DVD player. Iyakwazi ukufakwa ngokuzenzekelayo okanye ngokuzenzekelayo usebenzisa inyawo lomlenze we-rubber. Xa ixhunyiwe, i-DacMagic 100 yenza inkqubo yokuguqulwa kwedijithali-to-analog, edlalwa ngumdlali wediski, i-console yemidlalo, iseva yomculo okanye iPC.
I-DacMagic 100 ineempembelelo zemithombo emithathu yomsindo wedijithali - enye ingeniso ye- optical (i-Toslink) kunye neyesibini kwi- coaxial S / PDIF , kunye nefayile enye ye-USB yokuxhuma kwi-USB ye-output ye-PC okanye i-computer ye-MAC. Iziphumo ze-Analog zibandakanya umgca ongasebenzisekanga ( RCA ) kunye noqhagamshelwano olulinganisiweyo (XLR). I-digital pass-thru (kunye neToslink kunye ne-S / PDIF) inikwe ukuxhuma kwi-rekodi ye-digital audio.
Isifundo esifutshane (Isikolo esifutshane) kwisiXhobo seDivimenti
I-DacMagic 100 'isampuli' isignali yomsindo we-digital ukusuka kwi-16-bit / 44.1 kHz ukuya ku-24-bit / 192 kHz. Nangona ingxoxo epheleleyo yomsindo wedijithali ungaphaya kweli nqaku, kulungile ukutsho ukuba ukwandisa isantya esincane ukusuka kwi-16 ukuya kwi-24-bits kwandisa ubungakanani beesampuli nganye yezedijithali, kwaye uphakamise isalathisi engenazo yedijithali ukusuka kwi-44.1 kHz (i-sampuli ezingama-44,100 ngesibini) ukuya kuma-192 kHz (iisampuli ezingama-192,000 ngesibini), ukwandisa ubuninzi beetampu zedijithali ngeesibini. Iziphumo zikhulu kakhulu kwaye ziphakanyisiwe ukuphendula ngokuphindaphindiweyo kwimiqondiso ye-analog.
Enye into ebalulekileyo i-32-bit signal processing process ukwenzela ukunciphisa i-signal 'jitter'. I-Jitter yinto yomsindo wedijithali ehambelana nexesha leentshukumo zedijithali, ngamanye amaxesha zichazwa ngokuba 'zimpembelelo eziluhlaza.' Iwashi yedijithali echanekileyo, njenge-processor 32-bit, inceda ukunciphisa i-jitter yesiganeko kunye nokuphucula iinkcukacha eziphezulu kunye neendlela zokusombulula izibonakalisi. Ezinye izinto eziphawulekayo zeDacMagic 100 zibandakanya isalathisi sezinga lokungena sampampu (32, 44.1, 48, 88.2, kunye nama-sampling rates angama-96 kHz) kunye nezihlunu zedijithali ezintathu (L) ezingatshintshwa ngokuhambelana nokulalela. Ishintsho sepaneli esingaphambili sitshintsha ishintsho sinikezelwa ngeenjongo zokurekhoda ngejithali
Elingene Nezifundo Zenzululwazi - Ngaba i-DacMagic isebenza ngokwenene?
Ukuba unethemba lokuthatha umdlali wakho we-CD ophezulu kwiindawo eziphezulu zokusebenza, gcina imali yakho okanye utshale imali kwenye inkqubo yokuphucula. I-DacMagic 100 inobungakanani obuphezulu obuphezulu, kodwa mhlawumbi ayiyi kukhwela abadlali be-disc-end-end ekuhlaleni kwi-DACs ekwenzeni ukusebenza kwomsindo (ngaphandle kokuba iphelelwe yisikhathi). Ngakolunye uhlangothi, abaninzi abadlali be-CD kunye ne-DVD abanamanani atyunjiweyo banqamle ingqungquthela, ngokukodwa kwicala lomculo - yilapho iCambridge Audio DAC ibonise khona imilingo yayo.
I-DacMagic 100 ayenzi nto enkulu kumdlali wethu we-CD ophezulu we-CD, oye wahlala ephazamisekile apha. Zomibini ii-DAC zibonisa isisombululo esihle, iinkcukacha kunye nobunzulu. Nangona kunjalo, ukungafani kubonakala xa udlala iCD kwi-(esithengiweyo) umdlali we-Blu-ray kunye (nomdala) umdlali we-DVD-Audio / SACD. Ukwahluka komgangatho ozwakalayo kuyinto efihlekileyo kodwa nangona kunjalo isikhumbuzo sokuthi umgangatho womsindo maxa wambi uthathwa njengesiqulatho sesibini, njengento elandelayo. I-DacMagic 100 izandile ngakumbi evulekileyo kwaye ecacileyo xa kuthelekiswa nama-DAC aphakathi kwamanye abadlali. Nangona ulwahlulo lubonakala, lukwabaluleke kakhulu xa lufaniswa nokuphuculwa komsindo wekhompyutha.
Ngaba i-DacMagic iphakamisa ikhompyutheni kuMthombo woMculo oMthethweni?
Imilingo yangempela kwi-DacMagic 100 iyenzeka xa uphulaphule imithombo yomsindo wekhompyutha. I-DAC ezakhiwe kwiikhompyutheni ezininzi aziwa kumgangatho olalelwayo ngaphandle kokuba iicardscards zenziwe ngcono kangangoko. Xa ixhunyiwe kwi-USB ye-PC okanye ikhompyutha ye-MAC, i-DacMagic 100 isebenza njengomguquguquli we-digital-to-analog - ngokufana nekhadi elililo langaphandle elinomgangatho ophezulu we-DAC.
Uthelekiso luyinto ecacileyo. Isandi se-DacMagic 100 sigqiba ngokupheleleyo i-DAC esakhelwe kwi-laptop yethu ye-Mac, ngokukhawuleza iphakamise ikhompyutheni kwisixhobo somculo esisemthethweni. Ngomculo wonke ogcinwe kwikhompyutheni, ufana nokufumana ngokukhawuleza umthombo womculo omgangatho ophezulu wokudlala kwi-system. Umninzi womculo ogcinwe uvela kwi-iTunes kwifomati ye-AIFF, eyi-CD standard 44.1 kHz, umsindo we-16-bit. Ingxolo yekhwalithi ephakamileyo ukuqala, kodwa ukuphulaphula ngeDacMagic 100 kufana nokuphakamisa iingubo ezifihla iintetho.
Ukucaca kunye neenkcukacha ziphucula ngokuphawulekayo, ngokuvuleka okukhulu kunye nokungafihli. Ukuxhuma ikhomputha kulula. Xhuma ukukhishwa kwe-USB kwikhompyutheni kwi-USB engenayo kwi-DacMagic 100, uze uqhagamshele iDacMagic 100 analog output kwi-input analog kwi-receiver. Qaphela: i-DacMagic 100 ayifiki naliphi na iimbambo, ngoko kuya kufuneka uthenge ngokwahlukileyo. Ngaphandle kweekhomputer, i-DacMagic 100 inikezela ukuphuculwa kweengcamango zamanye amadivaysi alalelwayo kuquka: amaseva omculo, iinkqubo zomsindo wee-intanethi, abadlali bee-intanethi, iinkonzo zomsakazo we-satellite , abadlali beemidlalo zevidiyo, kunye nokuveliswa komsindo wedijithali kwithelevishini yeplanethi. Naliphi idivaysi yomsindo we-digital enezixhobo ezibonakalayo okanye ze-coaxial zingaxhunyezwa kwi-DacMagic 100 kwaye mhlawumbi ziya kuphucula umgangatho ophezulu.
Ngaphantsi
Kubonakala kuphawulekayo ukuba i-microchip encinci inokuba yinxalenye ebalulekileyo yechungechunge lomsindo, kodwa umguquleli we-digital-to-analog uqhuba umgangatho womculo. Iziphumo zakho zinokuhluka, kodwa ukongeza i-DacMagic 100 kwinkqubo inokuphucula isandi sabadlali abaninzi be-disc kunye nabasanda kutsha, ngokukodwa abo abangenayo impawu yomsindo ophuculweyo. I-DacMagic 100 izisa umsindo wekhompyutheni ebomini, iphakamisa iPC kwisixhobo somculo sangempela. Iikhompyutyhi ziye zaba yinto egcinwayo yokugcina umculo , kunye neDacMagic 100 ijika ikhompyutheni kwimithombo yomsindo ifanelekele ishedyuli yayo kwindawo yokuzonwabisa.
