DAC Topping E30 - mwachidule, mawonekedwe, mawonekedwe

Kampani yaku China Topping ndi m'modzi mwa osewera kwambiri pamsika wa zida za hi-fi zomwe zimapezeka kwa ogula wamba. Mwachitsanzo, mtengo wa DAC woyima wamtunduwu umayamba pa $ 110. Ndipo khalidweli limathandizidwa ndi ndemanga zambiri ndi ndemanga.

 

Topping E30 - ndichiyani?

 

DAC yosiyana (digital to analog converter) si yachilendo. Aliyense wodziwa phokoso lapamwamba angakwanitse kugula chipangizo choterocho, chomwe cholinga chake ndi kutembenuza chizindikiro cha digito ku analogi, pambuyo pofika kwa makampani aku China omwe akupikisana nawo pamsika. Ndipo amene akufuna kujowina iwo, kapena kungoyesa china chatsopano.

Ngati ma DAC akunja akale anali ndi kagawo kakang'ono, tsopano ndi zida zosunthika chifukwa cha mawonekedwe a USB. Izi zimawathandiza kuti azitha kulumikizidwa ku kompyuta komanso ku foni yamakono kapena piritsi. Kwenikweni, mukusintha khadi yomveka yamkati ndi DAC pogwiritsa ntchito analogi yake yapamwamba kwambiri. Ndipo kompyuta / foni yanu yam'manja imakhala ngati gwero (nthawi zambiri zosungira) nyimbo.

 

Topping E30 imatengedwa kuti ndi imodzi mwazinthu zopambana kwambiri potengera chiŵerengero cha mtengo / khalidwe. Mtunduwu ukhoza kukhala wofanana ndi ma Topping D50 odziwika bwino mugawo lazachuma. DAC ikuyambitsa mndandanda watsopano wamakampani, womwe umaphatikizanso ndi Topping L30 headphone amplifier. Mtengo wake ndi $ 150.

Kubwereza kwa E30 DAC

 

Topping E30 ndi "bokosi" lachitsulo loyera lokhala ndi 100x32x125mm (WHD) imvi, yakuda, yofiira kapena yabuluu.

Kutsogolo pali batani logwira la chosankha cholowetsa (kusintha), ndi batani losinthira kukhala standby mode, ikagwiridwa. Komanso chinsalu chosonyeza zomwe mwasankha komanso ma frequency amtundu wamtunduwu. Izi zitha kukhala zothandiza poyang'ana kulondola kwa siginecha yotumizidwa ndi makonda anu.

 

Kumbuyo kuli zotulutsa za RCA ("tulips") za amplifier, zolowetsa digito coaxial ndi kuwala kwa S / PDIF, kulowetsa kwa USB mtundu wa B, ndi cholumikizira mphamvu.

Mtolowu ulinso ndi chingwe cholimba cha USB-B cholumikiza chipangizocho ndi gwero lazizindikiro. Zinanso ndi remote control, warranty card, user manual ndi power cable.

Mphamvu ya DC / USB-A imakupatsani mwayi wogwiritsa ntchito makompyuta / laputopu ndi zida zakunja monga gwero. Kuyambira pa kulipiritsa foni yam'manja ndi PowerBank, kutha ndi mzere wopangira magetsi.

 

Kudzaza kumachitidwa ndi:

 

• DAC IC AK4493 from Asahi Kasei. Mtundu watsopano wa AK4490 wothandizira PCM 32bit 768kHz ndi mawonekedwe a DSD
• Receiver AK4118 yosinthira ma sigino kuchokera ku zolowetsa za S / PDIF. M'matembenuzidwe apambuyo pake, idasinthidwa ndi CS8416 kuchokera ku Cirrus Logic. Zikuoneka chifukwa chosowa tchipisi Asahi Kasei.
• USB chowongolera XMOS XU208.

 

Kuyesa Topping E30 pazinthu zosiyanasiyana

 

Topping imadziwika kuti imayika miyeso ya mawu a chipangizo chilichonse chomwe imapanga patsamba lake. Adapangidwa pogwiritsa ntchito Audio Precision APx555 audio analyzer. Komanso, deta iyi ingapezeke mu kabuku kapadera komwe kamabwera ndi chipangizocho.

 

Choyamba, izi zikusonyeza kuti tikhoza kuyang'ana makhalidwe enieni a chipangizocho. Popanda kudalira malonjezo a wopanga, komanso popanda kugwa pazidule ndi zidule zosiyanasiyana. Kuphatikiza apo, zida za Topping nthawi zambiri zimawunikiridwa pazinthu zodziwika bwino monga ASR (audiosciencereview). Kumene Audio Precision APx555 audio analyzer imagwiritsidwa ntchito poyezera.

Kutengera zotsatira za muyeso wa onse opanga ndi tsamba la ASR, zotsatirazi zitha kuganiziridwa:

 

Kuchuluka kwa siginecha pakuyezera, kHz	1
Mphamvu zotulutsa, Vrms	> 2
Total Harmonic Distortion + Noise (THD + N),%	<0.0003
Signal to noise ratio (SINAD), dB (malinga ndi ASR)	~ 114
Signal to noise ratio (SNR), dB (wopanga)	121
Dynamic range, dB	~ 118
Mtundu wopanda zosokoneza (multitone), pang'ono	20-22
Izi, dB	<-135

 

Jitter ikalumikizidwa kudzera pa mawonekedwe a S / PDIF ndiyokwera pang'ono. Komabe, nsonga zake zili pa -120 dB, zomwe sizofunikira.

 

Zithunzi za DAC Topping E30

 

Chofunikira chachikulu cha Topping E30 ndi kukhalapo kwa zolowetsa za digito za S / PDIF pamawonekedwe a "ogula". COAX (RCA, coaxial) ndi TOSLINK (optical), yomwe imakulolani kuti mugwirizane ndi chipangizo chilichonse chokhala ndi digito. Kuchokera pa TV ndi media player kupita ku CD yakale ya 80s.

 

Chinthu chinanso ndi preamplifier yomangidwa, yomwe imalola kuti DAC ilumikizidwe mwachindunji ndi amplifier mphamvu. Ngakhale, nthawi zambiri, mawonekedwewa amagwiritsidwa ntchito kusintha mawu kuchokera patali. Ngati palibe pa amplifier "yathunthu", yomwe nthawi zambiri imagwiritsidwa ntchito ndi okonda nyimbo.

Mbali imeneyi ili ndi zovuta zake. Mwakutero, kutayika kwa mphamvu ya chizindikiro chotulutsa. Komabe, izi sizikutanthauza kuwonongeka kwa kamvekedwe ka mawu. Pakuti chirichonse chidzadalira mkhalidwe yeniyeni ndi zoikamo wa Audio dongosolo.

 

AK4493 microcircuit ili ndi zosefera 6 zomvera za PCM ndi 2 za DSD m'bwalo kuti zithandizire kusintha pang'ono mawu.

 

Tsoka ilo, ntchitoyi imapezeka kokha kuchokera ku remote control. Ndipo izi zitha kuwoneka ngati zovuta kwa iwo omwe ali ndi DAC pafupi ndi kompyuta kapena laputopu.

 

Zithunzi za DAC Topping E30

 

Kusiyana kwakukulu pakati pa Topping E30 ndi zida zotsika mtengo ndi kupezeka kwa zolowetsa za S / PDIF monga mu "classic" DAC. Mwachitsanzo, mu mtundu wa Topping D10s, mawonekedwe a digito amakhala ngati zotuluka. Ndiye kuti, chipangizochi chitha kugwiritsidwa ntchito ngati chosinthira cha USB. Pakupanga ma sign mu S / PDIF kuti mudyetse ku DAC ina. Ngakhale, pali kukayikira kuti wogwiritsa ntchito wamba angafunike. The Topping D10s imatengedwa ngati USB DAC yokha. Monga zida zambiri zotsika mtengo. Chifukwa chake, ngati kupezeka kwa zolowetsa za S / PDIF ndikofunikira, ndiye kuti E30 ndi chisankho chabwino.

Malinga ndi chitsanzo kuchokera ku shenzhenaudio.com (zida zamtengo wapatali pansi pa $ 150), XDUOO MU-601 DAC imagwiritsa ntchito chip chip ES9018K2M. Koma palibe zolowetsa za digito (zokhazo za coaxial kuchokera pazotsatira). FX Audio D01 DAC idakhazikitsidwa kale pa chipangizo chaposachedwa cha ES9038Q2M. Ili ndi cholandirira cha Bluetooth chothandizira LDAC codec komanso chokulitsa cholumikizira cham'mutu. Pano ife tiri kale lonse "kuphatikiza".

 

Koma poganizira ma DAC ochokera kwa opanga ena, muyenera kulabadira kugwiritsa ntchito zida zina. Komanso, njira yosiyana yozungulira, ndipo, molingana ndi zizindikiro zina. Komanso, sizingatheke kuti kuphatikiza kwa mtengo womwewo kutulutsa phokoso la mlingo uwu, pambuyo pake, uli ndi ntchito yosiyana.

 

Njira ina yosangalatsa ndi Sanskrit 10 MKII yochokera ku mtundu wina wodziwika bwino waku China, SMSL. Zimakhazikitsidwa ndi chipangizo chomwecho cha AK4493. Koma amataya (malinga ndi ASR), poyerekeza ndi multitone ndi jitter, makamaka kwambiri mu S / PDIF. Ndani amene amayang'anira ma signature a S / PDIF akadali chinsinsi. Pazifukwa zina, wopanga sanasonyeze izi. Komabe, ziyenera kukumbukiridwa kuti chipangizochi chilinso ndi chowongolera chakutali. Pali preamp mode ndi zosefera zomangidwa mkati. Kupanga kopanda muyezo, osati kwa aliyense. Chophimbacho ndi chodzichepetsa kwambiri.

 

Zomaliza pa Topping E30

 

Pomaliza, nkosakayikitsa kunena kuti machitidwe ake abwino kwambiri a sonic, chithandizo chamitundumitundu komanso mawonekedwe opangidwa mwaluso zimapangitsa Topping E30 kukhala imodzi mwama DAC abwino kwambiri okhazikika pamitengo yake.

 

Ngati mukufuna kugula Topping E30 kuchokera kwa ogulitsa odalirika, pitani ku AliExpress pa izi... Kwa ndemanga imodzi, muwerenga za malonda ndi wogulitsa.
