Tempotec Sonata HD Pro - Ongorora
TempoTec Sonata HD Pro inorema 9 gramu chete. Iine chitarisiko chakareruka uye zviyero zve 47x17x8 mm, zvimwe zvisingawanzo kune dongles. Zvose izvi zvinobhadharwa nesimbi yakavimbika. Kunyangwe zvisingaratidzike mabhatani ekudzora anokutendera kuti ugadzirise vhoriyamu pasina kubvisa smartphone yako muhomwe yako. Izvo zvinofanirwa kucherechedzwa kuti iyi ndiyo vhoriyamu yemudziyo, kwete yako smartphone. Uye, zvinoita sekunge, yatove isina kujairika Micro-USB yekubatanidza. Izvi zvichawedzera kukwanisa kubatanidza chigadziro kune chinodiwa chigadziro kuburikidza nemaadapter, kusanganisira akazara.
Iyo yakazara seti inosanganisira yakasimba tin bhokisi, iyo, kuwedzera kune dongle, ine:
- Type-C kune Mirco-USB adapta.
- Type-C kune USB-A adapta.
- Hi-Res Audio sticker, iyo, sokunge zvakadaro, inosimbisa kuti chigadzirwa chinokubvumira kuteerera mimhanzi mukutsanangurwa kwepamusoro.
Mutengo weTempotec Sonata HD Pro ungangoita madhora makumi mashanu. Izvo zvakanakira basa rinonakidza rakadaro.
Mwoyo wemudziyo ndiyo Cirrus Logic CS43131 chip. Inosanganisa chizvarwa chitsva odhiyo DAC ine yepamusoro mhando yemusoro amplifier kuendesa yepamusoro ruzha rwemhando ine yakaderera simba rekushandisa.

Zvakaoma kuwana chero ruzivo pane iyo SA9312 USB controller, Savitech haigovane madheti. Iyo PLL (Phase Locked Loop) yeCS43131 pachayo ndiyo inonyanya kuita basa rekuisa chiratidzo. Chishandiso chinotsigira ASIO (Low Latency Data Transfer Protocol). Asi chete mushure mekuisa mutyairi, iyo inogona kutorwa kubva kune yepamutemo Tempotec webhusaiti (chete yeWindows). Zvinokosha kuziva kuti Windows 10 inotanga dongle kunze kwebhokisi, ndiko kuti, Plug uye Tamba chete.
Mugadziri anoratidza anotevera maodhiyo ekubuda kuyerwa:
- Chiratidzo kune ruzha reshiyo (SNR) - 128 dB.
- Dynamic range - 128 dB.
Iwe unogona kutarisa izvi nekuenda kune inozivikanwa sosi ASR (audiosciencereview), uko mudziyo uyu wakafambiswa kuburikidza neaudio analyzer. Kubva pane kuyerwa kwemhedzisiro yeASR saiti:
| Simba rekubuda, Vrms | 2 |
| Yakazara Harmonic Distortion + Noise (THD + N),% | 0.00035 |
| Signal to noise ratio (SINAD), dB | ~ 109 |
| Dynamic range, dB | 124 |
| Multitone bvunzo, zvishoma | 18-22 |
| Jitter bvunzo, dB | -130 (LF) / -140 |
Sezvakataurwa pa ASR, iyo multitone (yakawanda-toni bvunzo) inoratidza kushoma kushaya simba pane yakaderera frequencies.
Simba rekubuda pamutoro we300 ohms - 14 mW. Kuchinjira ku32 ohm mutoro wakakonzeresa kuchekerera. Iyi ndiyo imwe yemhando yekukanganisa inoitika kana amplifier yaremerwa uye kana iyo inobuda voltage yeamplifier ichipfuura iyo yekugovera voltage muganho uye, semhedzisiro, yakaderera simba - 66 mW.
Sezvauri kuona, yakakwira impedance mahedhifoni akaoma kune mudziyo. Tichifunga kuti isu tiri kufunga inotakurika midziyo yayo, izvi zvinogona kuregeredza zvishoma. Iyo yakasununguka vhoriyamu yekuchengetedza ye "yakasimba" mahedhifoni, zvisinei, ichapihwa.
Tempotec Sonata HD Pro: maitiro
Zvakakodzera kutaura zvakasiyana kuti stereo mini-jack headphone kubuda inoshandiswa chete kune chinangwa chayo. Ndiko kuti, dongle haigoni kuva nekutonga kwekunze. Iyo inotevera nguva inosanganiswawo nayo: kana plug yakabatana kune socket, mudziyo unotanga uye unotanga kushanda. Uye mushure mekuibvisa - pane zvinopesana, inochengetedza bhatiri re smartphone yako.
Iyo yakambosarudzwa Type-C kune USB-A adapta inogona kubatanidza Tempotec Sonata HD Pro pakombuta yako kana laptop. Uye shandisa iyo yakazara-yakazara DAC, sezvo hunhu hwechigadzirwa hunokubvumira kuita izvi.
Analogis Tempotec Sonata HD Pro
Pakati peanalogi muchikamu chemutengo (50 US madhora), zvinotevera zvishandiso zvinogona kusiyaniswa:
- iBasso DC02... Uyu ndomumwe wemapiyona eiyo inotakurika inotakurika Hi-F. Zvisinei, iyo inofananidzwa neDC02 modhi haibatsiri mukuenzanisa yakananga neSonata HD Pro. Simba rekubuda pasi (1Vrms), chiratidzo-ku-ruzha reshiyo (92dB vs.109dB) uye dhizaini ye91dB inoratidza izvi. Iyo jitter bvunzo inoratidzawo ruzha rwakanyanya, kunyangwe kunze kwenzeve. Iyo inozivikanwa chip kubva kuAsahi Kasei AK4490EQ haina kubatsira. Models kubva kuBasso inogona kukwikwidza neSonata HD Pro inodhura zvakanyanya.
- xDuoo batanidzo... Iyi analogi ine matambudziko akafanana neambotaurwa iBasso DC
- Periodic Audio Rhodium... Sechisarudzo muchikamu chimwe chete, asi neine mashoma truncated mabasa. Inongoburitsa 7mW pa32 Ohms. Hazvina musoro kugara pane zvakadzama maitiro. Iko hakuna rutsigiro rweDSD. Zviri mukati chinoramba chiri chakavanzika. Uye izvi zvinogadzira matambudziko kune vatengi vanofanirwa kunzwisisa zvavari kubhadhara mari yavo.
- Musiland MU1... Pamutengo wemadhora makumi matatu neshanu, inoratidza yakanakisa simba rekuchengetedza pane yakaderera-impedance mahedhifoni - 35mW (maererano neASR). Mugadziri anoratidza kuti dhizaini renji i29dB, uye iyo yakazara harmonic distortion + ruzha (THD + N) ndeye -114dB. Iyo yekupedzisira inosimbiswa neiyo ASR nhamba ye90dB. Dongle yakavakirwa pa USB dhijitari processor SuperDSP93 uye Cirrus Logic CS230L codec.
Uyezve, iyo yakakurumbira brand Hidizs ine mune yayo arsenal iyo S8 modhi, yakafanana mune Hardware uye maitiro, ayo anosiyana, pamwe, mune yakabudirira dhizaini. Asi inobuda pamadhora makumi matatu ekuwedzera. Uye izvi zvine masimba akafanana neTempotec Sonata HD Pro.
Mukupedzisa
Zvakachengeteka kutaura kuti kuita kwekuteerera kweTempotec Sonata HD Pro USB dongle pakati pevakwikwidzi muchikamu chemutengo hakupfuuri kurumbidzwa. Iyo inoshaya iyo yekumusoro yekumusoro impedance mahedhifoni. Asi maererano nemhando yeruzha, inogona kukwikwidza nemaDAC akamira, kunyangwe nekuchengetedza.
