Tempotec Sonata HD Pro USB dongle (amplifier + DAC)

Kuzimiririka kwa cholumikizira wamba cha TRS 3.5 (chodziwika bwino kuti stereo mini-jack) m'mafoni a m'manja kumakakamiza ogwiritsa ntchito kugwiritsa ntchito adaputala yonse. Chofunikira chachikulu kuti chikhale chokhazikika komanso chokhazikika. Nthawi zonse zimakhala zosangalatsa zomwe zili mkati mwa adaputala awa. Kupatula apo, ena mwa iwo ndi osinthira mafoni a digito-to-analog ndi amplifiers mu chipangizo chimodzi.

 

Izi zikusonyeza kuti foni yamakono iliyonse yamakono ikhoza kusinthidwa kukhala chosewerera chapamwamba kwambiri cha digito. Palibe mtengo wapadera. Sichidzakhala chotsika kwa zipangizo zapadera. Kuphatikiza apo, kusankha kwakukulu kwazinthu zotere kudzakuthandizani kupeza njira yoyenera pamakutu anu paokha komanso zomveka.

TempoTec yadziwika kale pamsika wa zida zomvera. Tsambali lili ndi osewera digito ndi ma DAC a USB, komanso makhadi amawu a PCI. Pamsika wamsika wama audio dongle, mtunduwo umapikisana ndi mndandanda wake wa Sonata, mtundu wa HD Pro womwe tikambirana mu ndemanga iyi.

Tempotec Sonata HD Pro - Ndemanga

 

TempoTec Sonata HD Pro imalemera magalamu 9 okha. Ili ndi mawonekedwe osavuta komanso miyeso ya 47x17x8 mm, yachilendo kwa ma dongles. Zonsezi zimalipidwa ndi chitsulo chodalirika. Ngakhale mabatani osawoneka bwino omwe amakulolani kuti musinthe voliyumu osatulutsa foni yamakono m'thumba lanu. Zindikirani kuti ichi ndi kuchuluka kwa chipangizocho, osati foni yamakono. Ndipo, zikuwoneka, kale cholumikizira cha Micro-USB chachilendo. Izi zidzawonjezera kuthekera kolumikiza chipangizo ku chipangizo chomwe mukufuna kudzera pa ma adapter, kuphatikiza athunthu.

Seti yathunthu imaphatikizapo bokosi lolimba la malata, lomwe, kuwonjezera pa dongle, lili ndi:

 

• Type-C kupita ku Mirco-USB adaputala.
• Type-C kupita ku USB-A adaputala.
• Chomata cha Hi-Res Audio, chomwe, titero, chimatsimikizira kuti chipangizocho chimakulolani kumvetsera nyimbo momveka bwino.

 

Mtengo wa Tempotec Sonata HD Pro ndi pafupifupi $ 50. Zomwe ndi zabwino kwambiri pakuchita kosangalatsa kotere.

Mtima wa chipangizocho ndi Cirrus Logic CS43131 chip. Imaphatikiza DAC yomvera ya m'badwo watsopano wokhala ndi chokweza chamutu chapamwamba kwambiri kuti chipereke mawu apamwamba kwambiri osagwiritsa ntchito mphamvu zochepa.

 

Chip magawo Tempotec Sonata HD Pro

 

Njira	2

Total Harmonic Distortion + Noise (THD + N), dB	-115
Sampuli pafupipafupi, kHz	384
Mphamvu ya analogi, V	1.8
Mphamvu zamagetsi zamagetsi, V	1.8
Kugwiritsa ntchito mphamvu pakugwiritsa ntchito, mW	6,25-40,2
Zotulutsa, Vrms	2 (mpaka 600 Ω)
Mphamvu yotulutsa pa tchanelo chilichonse, mW	-
32 ohm	30
600 ohm	5

 

Ndizovuta kupeza chidziwitso chilichonse pa chowongolera cha USB cha SA9312, Savitech sichigawana ma data. PLL (Phase Locked Loop) ya CS43131 yokha ndiyomwe imayang'anira mawotchi. Chipangizochi chimathandizira ASIO (Low Latency Data Transfer Protocol). Koma mutakhazikitsa dalaivala, yomwe imatha kutsitsidwa patsamba lovomerezeka la Tempotec (kwa Windows kokha). Ndizofunikira kudziwa kuti Windows 10 imayamba dongle m'bokosi, ndiye kuti, Pulagi ndi Sewerani basi.

Wopanga akuwonetsa miyeso yotsatirayi yotulutsa mawu:

 

• Chiŵerengero cha Signal to Noise (SNR) - 128 dB.
• Mtundu wamphamvu - 128 dB.

 

Mutha kuyang'ana izi popita ku gwero lodziwika bwino la ASR (audiosciencereview), pomwe chipangizochi chidayendetsedwa kudzera pa audio analyzer. Kutengera zotsatira za kuyeza kwa tsamba la ASR:

 

Mphamvu zotulutsa, Vrms	2
Total Harmonic Distortion + Noise (THD + N),%	0.00035
Signal to noise ratio (SINAD), dB	~ 109
Dynamic range, dB	124
Mayeso a Multitone, pang'ono	18-22
Mayeso a Jitter, dB	-130 (LF) / -140

 

Monga taonera pa ASR, ma multitone (mayeso amitundu yambiri) akuwonetsa kufooka pang'ono pama frequency otsika.

 

Kutulutsa mphamvu pa katundu wa 300 ohms - 14 mW. Kusintha kwa 32 ohm katundu kunayambitsa kudula. Ichi ndi chimodzi mwa mitundu yokhotakhota yomwe imachitika pamene amplifier yadzaza ndi pamene mphamvu yamagetsi ya amplifier imadutsa malire amagetsi ndipo, chifukwa chake, mphamvu yochepa - 66 mW.

Monga mukuonera, mahedifoni apamwamba a impedance ndi ovuta pa chipangizocho. Poganizira kuti tikuganizira zida zonyamulika za izo, izi zitha kunyalanyazidwa pang'ono. Kusungidwa kwa voliyumu yabwino kwa mahedifoni "zolimba", komabe, kudzaperekedwa.

 

Tempotec Sonata HD Pro: mawonekedwe

 

Ndikoyenera kutchula padera kuti kutulutsa kwamutu kwa stereo mini-jack kumagwiritsidwa ntchito pazolinga zake zokha. Ndiko kuti, dongle sangakhale ndi ulamuliro uliwonse wakunja. Mphindi yotsatirayi ikugwirizananso nayo: pulagi ikalumikizidwa ndi socket, chipangizocho chimayamba ndikuyamba kugwira ntchito. Ndipo mutatha kuchotsa - m'malo mwake, imapulumutsa batri ya smartphone yanu.

Adaputala ya Type-C yomwe idasankhidwa kale kupita ku USB-A imatha kulumikiza Tempotec Sonata HD Pro ku kompyuta yanu kapena laputopu. Ndipo gwiritsani ntchito ngati DAC yodzaza, popeza mawonekedwe a chipangizocho amakulolani kuchita izi.

 

Analogi Tempotec Sonata HD Pro

 

Pakati pa ma analogi omwe ali mgulu lamitengo iyi (madola 50 aku US), zida zotsatirazi zitha kusiyanitsa:

 

• iBaso DC02... Uyu ndi m'modzi mwa omwe adayambitsa Hi-F yotsika mtengo. Komabe, chofananira chofananira cha DC02 sichithandiza pakuyerekeza mwachindunji ndi Sonata HD Pro. Mphamvu zotsika zotulutsa (1Vrms), chiŵerengero cha signal-to-noise (92dB vs.109dB) ndi kusintha kwa 91dB kumasonyeza izi. Kuyesa kwa jitter kumawonetsanso phokoso lambiri, ngakhale mopanda makutu. Chip chodziwika bwino cha Asahi Kasei AK4490EQ sichinathandizenso. Zitsanzo zochokera ku iBasso zomwe zimatha kupikisana ndi Sonata HD Pro zidzakwera mtengo kwambiri.
• xDuuu Lumikizani... Analogi iyi ili ndi zovuta zofanana ndi zomwe tatchulazi iBasso DC
• Periodic Audio Rhodium... Monga njira mu gawo lomwelo, koma ndi ntchito zochepa zochepa. Imapanga 7mW yokha pa 32 Ohms. Ndizosamveka kumangokhalira kuganizira zatsatanetsatane. Palibe chithandizo cha DSD. Zomwe zili mkatimu sizikudziwika. Ndipo izi zimabweretsa mavuto kwa ogula omwe amafunika kumvetsetsa zomwe akulipira ndalama zawo.
• Musiland MU1... Pamtengo wa $ 35, ikuwonetsa malo abwino osungira magetsi pamakutu otsika - 29mW (malinga ndi ASR). Wopanga akuwonetsa kuti mitundu yosunthika ndi 114dB, ndipo kusokoneza kwathunthu + phokoso (THD + N) ndi -90dB. Chotsatiracho chikutsimikiziridwa ndi chiwerengero cha ASR cha 93dB. Dongle imachokera pa purosesa ya digito ya USB SuperDSP230 ndi Cirrus Logic CS42L codec

 

Kuphatikiza apo, mtundu wotchuka wa Hidizs uli ndi zida zake zamtundu wa S8, zofanana ndi zida ndi mawonekedwe, zomwe zimasiyana, mwina, pamapangidwe opambana. Koma zimatuluka pa $ 30 zina. Ndipo izi ndizofanana ndi Tempotec Sonata HD Pro.

 

Pomaliza

 

Ndizosakayikitsa kunena kuti machitidwe omvera a Tempotec Sonata HD Pro USB dongle pakati pa omwe akupikisana nawo pagulu lamitengo yake satamandidwa. Ilibe chimbudzi cha mahedifoni apamwamba a impedance. Koma kutengera mtundu wamawu, imatha kupikisana ndi ma DAC osayima, ngakhale kusungitsa malo.
