DAC Topping E30 - wongororo, tsanangudzo, maitiro
Kambani yeChinese Topping ndeimwe yevatambi vakuru mumusika wehi-fi michina inowanikwa kunewo zvavo vatengi. Mutengo, semuenzaniso, weiyo yakamira yeDAC yemhando iyi inotangira pamadhora zana negumi. Uye iyo mhando inotsigirwa neakawanda wongororo uye wongororo.
Topping E30 - chii ichocho
DAC yakaparadzana (digital to analog converter) haina kujairika. Chero chero nyanzvi yemhando yepamusoro-soro inogona kutenga chigadzirwa chakadaro, chinangwa chacho ndechekushandura chiratidzo chedhijitari kune analog, mushure mekusvika kwemakwikwi eChinese brands pamusika. Uye uyo anoda kubatana navo, kana kungoedza chimwe chinhu chitsva.
Kana kare maDAC ekunze akatora imwe niche, ikozvino atova maturusi akawanda nekuda kwekuvapo kwe USB interface. Izvi zvinovabvumira kuti vabatanidzwe zvese pakombuta uye kune smartphone kana piritsi. Chaizvoizvo, uri kutsiva yakajairwa yemukati inonzwika kadhi neDAC uchishandisa yayo yepamusoro mhando analogue. Uye komputa yako / smartphone inoita sosi (kazhinji chengetedzo) yemimhanzi yemukati.
Topping E30 inoonekwa seimwe yeakanyanya kubudirira modhi maererano nemutengo / mhando reshiyo. Iyo modhi inogona kunyatso kuve analogue yeavhareji inozivikanwa Topping D50s mune imwe bhajeti chikamu. Iyo DAC inosvitsa iyo kambani mutsara mutsva, iyo inosanganisirawo Topping L30 musoro wefoni amplifier. Mari yacho ndeye $150.

Topping E30 DAC Ongororo
Topping E30 isimbi diki yakatsvinda "bhokisi" inoyera chete 100x32x125mm (WHD) grey, dema, tsvuku kana bhuruu.
Kumberi kune bhatani rekubata rekuisa sector (kuchinja), iro zvakare bhatani rekuchinja kune standby mode, kana rakabatwa. Uye zvakare chidzitiro chinoratidza iyo yakasarudzwa yekupinda uye yazvino frequency yezwi rezwi. Izvi zvinogona kubatsira pakutarisa iko kurongeka kwechiratidzo chinofambiswa uye yako sosi marongero.
Kumashure kune RCA zvinobuda ("tulips") zveamplifier, digital coaxial uye optical S / PDIF zvekupinza, USB mhando B yekuisa, uye simba rekubatanidza.
Iyo bundle inotosanganisira yakasimba USB-B tambo yekubatanidza mudziyo kune siginecha sosi. Zvakare inosanganisirwa kuremote control, waranti kadhi, bhuku remushandisi uye tambo yemagetsi.
DC / USB-Simba remagetsi rinokutendera kuti ushandise ese komputa / laptop uye ekunze zvishandiso sesosi. Kutanga kubva pakuchaja smartphone uye PowerBank, ichipera nemutsara wemagetsi emagetsi unit.
Kuzadza kunoitwa ne:
- DAC IC AK4493 kubva kuAsahi Kasei. Shanduro itsva yepremium AK4490 inotsigira PCM 32bit 768kHz uye DSD mafomati
- Receiver AK4118 yekugadziriswa kwemasaini kubva kuS / PDIF mapipu. Mune shanduro dzakazotevera, yakatsiviwa neCS8416 kubva kuCirrus Logic. Sezviri pachena nekuda kwekushaikwa kwemachipi kubva kuAsahi Kasei.

Kuedza Topping E30 pane zvakasiyana zviwanikwa
Topping ine mukurumbira wekutumira zviyero zvemutsindo zvechero mudziyo wainogadzira pawebhusaiti yayo. Ivo vakagadzirwa vachishandisa iyo Audio Precision APx555 audio analyzer. Zvakare, idzi data dzinogona kuwanikwa mune yakakosha kabhuku kanouya nemudziyo.
Chokutanga pane zvose, izvi zvinoratidza kuti tinogona kutarisa maitiro chaiwo echigadzirwa. Pasina kuvimba nezvipikirwa zvemugadziri, uye pasina kuwira kune zvakasiyana-siyana mazano uye mazano. Uyezve, zvishandiso zveTopping zvinowanzoongororwa pane inozivikanwa sosi yeASR (audiosciencereview). Iko iyo Audio Precision APx555 audio analyzer inoshandiswa kuyerwa.
Zvichienderana nemhedzisiro yekuyerwa kwemugadziri uye webhusaiti yeASR, zvinotevera zvinogona kutorwa:
| Chiratidzo frequency yezviyero, kHz | 1 |
| Simba rekubuda, Vrms | > 2 |
| Yakazara Harmonic Distortion + Noise (THD + N),% | <0.0003 |
| Signal to noise ratio (SINAD), dB (maererano neASR) | ~ 114 |
| Signal to noise ratio (SNR), dB (nemugadziri) | 121 |
| Dynamic range, dB | ~ 118 |
| Distortion-yemahara renji (multitone), bit | 20-22 |
| Jita, dB | <-135 |
Iyo jitter kana yakabatana kuburikidza neS / PDIF interface iri pamusoro zvishoma. Nekudaro, iwo mapikisi ari pa -120 dB, izvo zvisina kutsoropodza.
Zvimiro zveDAC Topping E30
Chinhu chikuru cheTopping E30 kuvepo kwedhijitari S / PDIF yekupinda pane yakajairwa "mutengi" nzvimbo. COAX (RCA, coaxial) uye TOSLINK (optical), iyo inokubvumira kuti ubatanidze chero mudziyo une digital inobuda kwairi. Kubva paTV uye media player kusvika kune yekare CD player kubva kuma80s.
Chimwe chinhu ndeye yakavakirwa-mukati preamplifier, iyo inobvumira iyo DAC kuti ibatanidzwe zvakananga kune iyo simba amplifier. Kunyangwe, kazhinji, chimiro ichi chinoshandiswa kugadzirisa ruzha kubva kure kure. Kana pasina pa "full" amplifier, iyo inowanzoshandiswa nevadi vemimhanzi.
Chimiro ichi chine matambudziko acho. Kureva, kurasikirwa kwesimba rechiratidzo chekubuda. Nekudaro, izvi hazvireve kuderera kwemhando yenzwi. Kune zvese zvinoenderana nemamiriro chaiwo uye marongero eiyo audio system.
Iyo AK4493 microcircuit ine pabhodhi 6 mafirita ePCM uye 2 yeDSD kubatsira zvishoma kuchinja manzwi.
Sezvineiwo, mabasa aya anongowanikwa kubva kuremote control. Uye izvi zvingaite sezvisina basa kune avo vane DAC padyo nekombuta kana laptop.
Analogis DAC Topping E30
Musiyano mukuru pakati peTopping E30 uye yakachipa zvishandiso kuvepo kweS / PDIF zvekupinza sezviri mu "classic" DAC. Semuenzaniso, muTopping D10s modhi, madhijitari anopindirana anoita sezvinobuda. Kureva, mudziyo uyu unogona kushandiswa se USB converter. Yekugadziriswa kwemasaini muS / PDIF yekudyisa kune imwe DAC. Kunyangwe, pane kusahadzika kuti mushandisiwo zvake angazvida. Iyo Topping D10s inoonekwa se USB DAC chete. Kufanana nemidziyo yakawanda yemutengo wakaderera. Saka, kana kuvapo kweS / PDIF zvekupinza kwakakosha, saka E30 isarudzo inobatsira.
Zvinoenderana nemuenzaniso kubva kushenzhenaudio.com (midziyo ine mutengo uri pasi pemadhora zana nemakumi mashanu), iyo XDUOO MU-150 DAC inoshandisa iyo ES601K9018M nhare chip. Asi hapana zvekupinza zvedhijitari (chete coaxial kubva kune zvakabuda). Iyo FX Audio D2 DAC yatove yakavakirwa pane ichangoburwa ES01Q9038M chip. Iri mubhodhi inogamuchira yeBluetooth ine rutsigiro rweLDAC codec uye yakavakirwa-mukati mahedhifoni amplifier. Pano tatova ne "combine" yose.
Asi uchifunga nezveDACs kubva kune vamwe vanogadzira, iwe unofanirwa kuterera kune kushandiswa kwezvimwe zvikamu. Uyezve, imwe nzira yedunhu yakasiyana, uye, maererano, kune zvimwe zviratidzo. Uyezve, hazvigoneki kuti kusanganiswa kwemutengo mumwe chete kunobudisa inzwi rezinga iri, shure kwezvose, rine kushandiswa kwakasiyana.
Imwe nzira inonakidza ndeyeSanskrit yechigumi MKII kubva kune imwe inozivikanwa Chinese brand, SMSL. Iyo yakavakirwa pane imwechete AK10 chip. Asi inorasikirwa (maererano neASR), mukuenzanisa nemultitone uye jitter, kunyanya zvakasimba muS / PDIF. Ndiani ari kutungamira iyo S / PDIF chiratidzo chekugadzirisa chinoramba chiri chakavanzika. Nokuda kwechimwe chikonzero, mugadziri haana kuratidza izvi. Nekudaro, zvinofanirwa kucherechedzwa kuti mudziyo uyu zvakare une remote control. Iko kune preamp modhi uye yakavakirwa-mukati maodhiyo mafirita. Non-standard dhizaini, kwete yemunhu wese. Iyo skrini ine mwero zvakanyanya.
Mhedziso paTopping E30
Mukupedzisa, zvakachengeteka kutaura kuti kuita kwayo kwakanaka sonic, kutsigirwa kwefomati yakakura uye dhizaini yakanyatsogadzirwa inoita iyo Topping E30 imwe yeakanakisa akamira maDAC mumutengo wayo.
Kana iwe uchida kutenga Topping E30 kubva kumutengesi akavimbika, enda kuAliExpress pa iyi link... Kune imwe wongororo, iwe uchaverenga nezve chigadzirwa uye mutengesi.
