Kuvandudza Audio Performance neAboardboard DAC
Munyika yenzwi redhijiti, mutambo wemagumo ndeyekunze kwekugadzira-digital-an-analog , kana DAC. Izvi zviduku, zvisingatauri zvinyorwa zvinowanikwa mune diski player kana pakombiyuta uye ndizvo zviyi zvekuchinja zvakarurama mabhiriyoni e-0s uye 1s yechiratidzo chemajeri (zvichibva pane CD kana DVD) muchiratidzo chekufananidzira kweanalogog iyo yakatendeka kune rwiyo rwepakutanga.
DAC ndiyo nheyo yehurukuro ye digital. Kuvandudza nokukurumidza mune teknolojia uye kuwedzera mukuzivikanwa kwemafaira / kombiyuta audio zvakagadzirisa kuda kweDACs kunze. Izvozvi zvikamu zvakagadzirirwa kuvandudza manzwiro ehurukuro eve disc players, makombiyuta, mitambo yemutambo , nezvimwe zvemashoko e digital .
Cambridge Audio DacMagic
DacMagic 100 inyaya yepamusoro yeDAC inowanikwa neCambridge Audio, muBritain. Kubvira muna 1968, Cambridge Audio yakapa pakati pekumusoro-soro AV zvikamu, midziyo, uye mini zvigadziriro. DacMagic 100 chikamu chiduku, kuenzanisa ne 1/3 ukuru hwemukati wemasikirwo akaenzana kana DVD player. Inogona kuiswa pasi kana kuti yakananga kuburikidza nerutsoka rwebhora rakapiwa. Kana yakabatanidzwa, DacMagic 100 inoita shanduro yekuita-digital-analogog, iyo inowanzoitwa ne diski player, game console, music server, kana PC.
DacMagic 100 ine zvinyorwa zvemashoko matatu ehurukuro yerinzwi - chimwe chinhu chinopinza maziso (Toslink) uye maviri e coaxial S / PDIF , uye imwe chete yeIndaneti inobatanidza kubudiswa kweIndaneti audio kubva kune PC kana MAC kombiyuta. Analog dzakabuda dzinosanganisira unbalanced-line ( RCA ) uye kuenzanisa-line (XLR). A digital pass-thru (neToslink uye S / PDIF) inopiwa kuti iungane kune imwe digital audio recorder.
A (Very Very) Chidzidzo Pfupi mu Digital Digital Audio
DacMagic 100 'upsamples' chiratidzo che digital audio kubva 16-bit / 44.1 kHz kusvika 24-bit / 192 kHz. Kunyangwe nhaurirano yakakwana yehurukuro yerudijeri iri kunze kwechikamu chino, zvakakwana kutaura kuti kuwedzera kwechidimbu kubva kuma16 kusvika ku 24-bits kunowedzera ukuru hwemuenzaniso umwe neumwe we digiti, uye kuwedzera upi hwechiratidzo chechidijito chinobva ku 44.1 kHz (44 100 samples pamusi wechipiri) kusvika 192 kHz (192,000 sampuli pamusi wechipiri), inowedzera huwandu hwema digital pulses sampled per second. Zvigumisiro zvinowedzera simba rakakura uye rinowedzera huwandu hwemashoko ehuwandu hwechiratidzo cheanalogog yakabuda.
Chimwe chinhu chakakosha chinonzi 32-bit signal processing kuitira kuderedza chiratidzo 'jitter.' Jitter iyi inonzi digital audio phenomenon yakabatana nenguva yekufambisa kwema digital, dzimwe nguva inotsanangurwa se 'shaky pulses.' Inonzi digital clock, yakadai se-32-bit processor, inobatsira kuderedza signal jitter uye inovandudza tsanangudzo yepamusoro yepamusoro uye kugadzirisa zviratidzo. Zvimwe zvinonyanya kuzivikanwa zveDacMagic 100 zvinosanganisira iyo inopinda sampling rate indicator (32, 44.1, 48, 88.2, uye 96 kHz sampling rates) uye nhatu filters (L) dzinogona kugadziriswa maererano nekuteerera zvaunoda. Pamberi pepane nharaunda invert switch inenge yakagadzirirwa chinangwa chekurekodha.
Zvakakwana Nezvidzidzo zveSayenzi - DacMagic Inoshanda Zvechokwadi Here?
Kana uri kutarisira kutora dhidhi yako yepamusoro yeDVD kumatunhu matsva ekuchengetedza, ita mari yako kana kuisa mune imwe shanduro kuvandudza. DacMagic 100 ine unhu hwakanaka hwehutano hwakanaka, asi zvichida haisi kuzokwanisa kuparadzanisa vatambi vekupedzisira-yekupedzisira yekodha ine maDAC dzakagadzirirwa kuti zviitwe zvakanaka (kunze kwekuti dzisina nguva yakareba). Kune rumwe rutivi, vazhinji vari pasi-kusvika pakati pamatengo eCD nemavhidhiyo eDVD vanocheka makona, kunyanya pamakanzwi ehurukuro - iyi ndiyo iyo Cambridge Audio DAC yakaratidza mamwe emashiripiti ayo.
DacMagic 100 haina kuita zvakawanda pamusana wedu wepamukuru weCom Yamaha CD player, iyo yakagara ichiita zvakanaka-hazvishamisi pano. Zvose DAC dzinoratidza chisarudzo chakanakisisa, tsanangudzo, nekudzika. Zvisinei, kusiyana kunonyanya kujekesa paunenge uchitamba CD pane (achangobva kutengwa) Blu-ray player uye (mukuru) DVD-Audio / SACD player. Kusiyana kwehutano hwakanaka kune hunyengeri asi zvisinei chiyeuchidzo chokuti hutano hwemhanzi dzimwe nguva hunofungidzirwa sechipiri, sekutevera. DacMagic 100 inonzwika zvishoma kana yakazaruka uye yakanyatsorondedzerwa kana ichienzaniswa nedzimwe DAC dzakawanda kune vamwe vatambi. Kunyange zvazvo kusiyana kwacho kuri kuonekwa, uyewo kunokosha zvikuru kana kuchienzaniswa nekuvandudzika kwekombiyuta audio.
Ko DacMagic Inogona Kuwedzera Takombiyuta Kumutauro Wemutemo Wakanaka Here?
Iko magetsi chaiwo muDacMagic 100 inoitika kana uchiteerera makombiyuta emitambo yemanzwi. DAC dzakavakwa mumakombiyuta akawanda hazvizivikanwi nehutano hwekutinhira kunze kwekuti mapepa evhadhidhi akavandudzwa saizvozvo. Kana yakabatanidzwa ku USB yakabuda pakombiyuta kana pamakombiyuta eMAC, DacMagic 100 inoshandura sevashanduri vedhijitori-analog - zvakangofanana nekodhi yekunze yakananga ine DAC dzakakwirira.
Kuenzanisa kwacho kwakanyanya. Inzwi reDacMagic 100 rinopedza zvachose DAC rakagadzirwa muMac laptop yedu, nekukurumidza kuisa kombiyuta kumutauro unoteerera. Neyese mimhanzi yakachengetwa pamakombiyuta, zvinoita kunge pakarepo kuwana chikwata chepamusoro-soro rehurukuro yekutamba pa system. Zvizhinji zvemimhanzi yakachengetwa inobva iTunes muAIFF format, iyo inonzi CD standard 44.1 kHz, 16-bit audio. Ndiyo yakakwirira yehutori yekutanga kutanga, asi kuteerera kuburikidza neDacMagic 100 kwakafanana nekusimudza jasi rinoputira vatauri.
Kunatswa uye zvinyorwa zvinowedzera zvakajeka, nekuzarura kukuru uye pachena. Kubatanidza kombiyuta iri nyore. Gadzirai USB output yekombiyuta kuInjini yeDacMagic 100, uye gadzirai DacMagic 100 analog yakabuda kune analog input pane anogamuchira. Cherechedza: DacMagic 100 haina kuuya nemakumbo, saka iwe unofanira kuitenga zvakasiyana. Kunze kwemakombiyuta, DacMagic 100 inopa maitiro ekuvandudza mamwe majeri ezwi, kusanganisira: mavhidhiyo emimhanzi, maitirwo emitambo yeimba yose , vateereri vemainternet, mapurogiramu emasitereti emitambo , vhidhiyo mitambo yemavhidhiyo, uye kunyange mutambo wemavhidhiyo ekubudiswa kweterevhizheni yemagetsi. Chero ipi zvayo yedhidhiyo audio audio ine optical kana coaxial outputs inogona kushamwaridzana neDacMagic 100 uye inogona kunge yakagadziridzwa kunaka kwehutano.
The Bottom Line
Zvinoratidzika zvinoshamisa kuti microchip duku inogona kunge yakakosha chikamu chetambo yakanzwika, asi mutengesi wemagetsi-analogo inotungamirira unhu hwekutinhira. Zviwanikwa zvako zvinogona kusiyana, asi kuwedzera DacMagic 100 kune imwe nzira inogona kuvandudza inzwi revatambi vakawanda vekare rekutamba uye kunyange vamwe vatsva, kunyanya avo vasina kusimbiswa nhepfenyuro dzemhanzi. DacMagic 100 inounza kombiyuta yehupenyu kuhupenyu, inosimudza PC kumhanzi chaiyo wekunzwa. Makombiyuta ave musimboti wekuchengetedza mimhanzi , uye DacMagic 100 inoshandura kombiyuta mumutauro unonzwa wakafanirwa neshefu yayo mune imwe nzvimbo yekuvaraidza.
