Ukuthuthukisa ukusebenza komsindo nge-Outboard DAC
Ezweni lomsindo wedijithali, umdlalo wokuphela ungumguquli wangaphandle we-digital-to-analog , noma i-DAC. Lezi microchips ezincane ezingezona ezichazayo zakhiwe kubadlali be-disk noma ikhompyutheni futhi ziyizihluthulelo zokuguqula ngokunembile izigidigidi ze-0s no-1 zesignali yomsindo wedijithali (isb. Kusuka ku-CD noma i-DVD) kumpawu zemvelo ezizwakalayo ezenzakalelayo umsindo wokuqala.
I-DAC iyinhloko yomsindo wedijithali. Ukuthuthukiswa okusheshayo kwezobuchwepheshe kanye nokuphakama kokuthandwa komsindo / wekhompyutha kuye kwaqhubekela phambili isidingo samaDAC angaphandle. Lezi zakhi zenzelwe ukuthuthukisa ukusebenza komsindo kwabadlali be-disc, amakhompiyutha, izidakamizwa zegeyimu , neminye imithombo yomsindo wedijithali .
I-Cambridge Audio DacMagic
I-DacMagic 100 iyisimo sokuphrinta ngaphandle kwe-DAC enikezwa yi-Cambridge Audio, umkhiqizi wase-UK. Kusukela ngo-1968, i-Cambridge Audio inikeze izingxenye eziphezulu ze-AV, izesekeli kanye nezinhlelo ze-mini. I-DacMagic 100 iyincenye encane, ilinganisa cishe 1/3 ubukhulu bomamukeli ophakathi nendawo noma i-DVD player. Ingafakwa ngokuzenzekelayo noma ngokuzenzekelayo usebenzisa inyawo lensiza yensiza. Uma uxhumekile, i-DacMagic 100 yenza inqubo yokuguqula i-digital-to-analog, ngokuvamile eyenziwa ngediski yediski, i-console yemidlalo, iseva yomculo, noma i-PC.
I-DacMagic 100 inezimpendulo zemithombo emithathu yomsindo wedijithali - okokufaka okukodwa kwe- optical (Toslink) kanye ne- coaxial S / PDIF , kanye nokufaka okukodwa kwe-USB kokuxhumeka kokukhipha umsindo we-USB wekhompyutha noma i-MAC computer. Iziphumo ze-Analog zihlanganisa ukungaxhunyiwe-line ( RCA ) nokuxhumana okulinganayo (XLR). I-digital pass-thru (nge-Toslink ne-S / PDIF) inikezwa ukuxhuma kumrekhodi womculo we-digital.
Isifundo esifushane (Esijulile) ku-Audio Digital
Isampula ye-DacMagic 100 'isignali yomsindo we-digital kusuka ku-16-bit / 44.1 kHz kuya ku-24-bit / 192 kHz. Nakuba ingxoxo egcwele yomsindo wedijithali ingaphezu kwalesi sihloko, kunelungelo lokuthi ukukhulisa inani elincane kusuka ku-16 kuya ku-24-bits kuzandisa ubukhulu besampuli ngayinye ye-digital, futhi kushintshwe isignali yedijithali engenayo kusuka ku-44.1 kHz (amasampula angu-44 100 ngomzuzwana) kuya ku-192 kHz (amasampula angu-192,000 ngomzuzwana), kwandisa ubungakanani be-pulp digital sampled ngomzuzwana. Imiphumela yikhulu elikhulu kakhulu futhi isetshenziselwa impendulo ephezulu yemvamisa yesibonakaliso se-analog.
Esinye isici esibalulekile ukucubungula isibonakaliso se-32-bit ukunciphisa isisindo 'sejitter'. I-Jitter iyinhlangano yomsindo wedijithali ehlobene nesikhathi sokufiphaza kwe-digital, ngezinye izikhathi kuchazwa ngokuthi 'ukushayela okukhulu.' Iwashi yedijithali enembile, njengeprosesa engu-32-bit, isiza ukunciphisa i-signal jitter futhi ithuthukise imininingwane ephezulu yemvamisa nokuxazululwa kwesignali. Ezinye izici eziphawulekayo ze-DacMagic 100 zifaka isibonakaliso sezinga lokungena sampula (32, 44.1, 48, 88.2, kanye namazinga angu-96 kHz sampula) kanye nezihlungi ezintathu zedijithali (L) ezingalungiswa ngokuvumelana nezintandokazi zokulalela. Isigaba sangaphambili sepaneli sokuguqula ishintshe sinikezelwe ngezinhloso zokurekhoda kwedijithali.
Kwanele Ngezifundo Zezesayensi - Ingabe I-DacMagic Isebenza Ngempela?
Uma unethemba lokuthatha isidlali sakho se-CD esiphezulu ekuphakameni okusha, gcina imali yakho noma ubeke imali kwezinye izinhlelo zokuthuthukisa. I-DacMagic 100 inekhwalithi yekhwalithi ephezulu kakhulu, kodwa cishe ngeke iphinde iphumelele abadlali be-disc abaphezulu abaphethe ama-DAC anakhelwe kahle ukusebenza komsindo (ngaphandle uma bephelelwe yisikhathi). Ngakolunye uhlangothi, abaningi abadlali abancane abaphakathi kwe-CD ne-DVD badonsa izingqimba, ikakhulukazi ohlangothini lwamazwi - yilapho i-Cambridge Audio's DAC ibonise khona eminye imilingo yayo.
I-DacMagic 100 ayenzi okuningi kumdlali wethu we-CD ophezulu wokugcina we-CD, owake wazwakala kakhulu-akumangalisi lapha. Zombili i-DAC ibonisa isinqumo esihle, imininingwane, nokujula. Noma kunjalo, umehluko uveza ngokwengeziwe uma udlala i-CD kumdlali we-Blu-ray (osanda kuthengwa) kanye nomdlali (omdala) we-DVD-Audio / SACD. Ukungezwani kwekhwalithi ezwakalayo kuyisimanga kodwa nokho yisikhumbuzo sokuthi ikhwalithi yomsindo ngezinye izikhathi ibhekwa njengesibili, njengokulandela. I-DacMagic 100 izwakala kancane kakhulu evulekile futhi eningiliziwe uma iqhathaniswa namaDAC ajwayelekile phakathi kokubili abanye abadlali. Nakuba ukungafani kubonakala, futhi kubalulekile kakhulu uma kuqhathaniswa nokuthuthukiswa komsindo wekhompyutha.
Ingabe i-DacMagic iphakamisa ikhompyutha kumthombo womsindo osemthethweni?
Umlingo wangempela ku-DacMagic 100 kwenzeka uma ulalela imithombo yomsindo wekhompyutheni. I-DAC ezakhiwe kuma-computer amaningi aziwa ngekhwalithi yomsindo ngaphandle kokuthi amakhodi e-soundcards asethuthukisiwe ngaleyo ndlela. Uma uxhumeke ekukhishwe kwe-USB kwekhompyutha noma ye-MAC ikhompyutha, i-DacMagic 100 isebenza njengenguquko ye-digital-to-analog - ngokufana nekhadi lezwi langaphandle elinama-DAC aphezulu.
Ukuqhathaniswa kuyaqakathekile. Umsindo we-DacMagic 100 uqeda ngokuphelele ama-DAC owakhiwe kwi-laptop yethu ye-Mac, ngokushesha ukuphakamisa ikhompyutha kumthombo wezwi ovumelekile. Ngomculo wonke ogcinwe kukhompyutha, kufana nokuthola ngokushesha umthombo womculo wekhwalithi eliphezulu wokudlala kuhlelo. Umculo omningi ogcinwe uvela ku-iTunes kwifomethi ye-AIFF, okuyi-CD evamile engu-44.1 kHz, umsindo we-16-bit. Ingoma yekhwalithi ephezulu ukuqala, kodwa ukulalela nge-DacMagic 100 kufana nokuphakamisa ijazi elimboza izikhulumi.
Ukucaca nemininingwane kuthuthukiswa ngokuphawulekayo, ngokuvuleka okukhulu nakakhulu. Ukuxhuma ikhompyutha kulula. Xhuma ukukhishwa kwe-USB kwikhompyutha ekufakweni kwe-USB ku-DacMagic 100, bese uxhuma ukukhishwa kwe-analog engu-DacMagic 100 ku-input analog kumamukeli. Qaphela: i-DacMagic 100 ayifuni nanoma yiziphi izintambo, ngakho-ke uzodinga ukuzithenga ngokwehlukana. Ngaphandle kwamakhompiyutha, i-DacMagic 100 inikeza ukuthuthukiswa komsindo kwamanye amadivaysi alalelwayo kubandakanya: amaseva omculo, izinhlelo zomsindo wonke wendawo, abadlali be-inthanethi, imisakazo ye-satellites , abadlali begeyimu yevidiyo, kanye nokukhishwa kwomsindo we-digital we-flat panel yethelevishini. Noma iyiphi idivaysi yomsindo we-digital enezici ezibonakalayo noma ze-coaxial ingaxhunyaniswa ku-DacMagic 100 futhi cishe izobhekana nekhwalithi yezwi ethuthukisiwe.
Okubalulekile
Kubonakala kuyamangalisa ukuthi i-microchip encane ingaba yingxenye ebaluleke kakhulu yohlu lwe-audio, kodwa umguquli we-digital-to-analog uqhuba ikhwalithi yomsindo. Imiphumela yakho ingahluka, kepha ukufaka i-DacMagic 100 ohlelweni kungenzeka ukuthi ithuthukise umsindo wabadlali abaningi be-disk asebekhulile ngisho nalabo abasha, ikakhulukazi labo abangenakho izici zomsindo ezithuthukisiwe. I-DacMagic 100 iletha umsindo wekhompiyutha empilweni, iphakamisa i-PC kumthombo wezwi oqobo. Amakhompiyutha abe yidivayisi yesitoreji yomculo ethandwayo, futhi i-DacMagic 100 iphendulela ikhompyutha emthonjeni womsindo ofanele ishalalo sayo esikhungweni sokuzijabulisa.
