Teac UD-301-X USB DAC - dulmar, muuqaalada
Wakiilka Tixraaca 301 ee khadka - Teac UD-301-X USB-DAC way ka duwan tahay dhigeeda cabbirrada la dhimay iyo muuqaal hoose. Laakiin tani gabi ahaanba ma saamayn tayadeeda. Intaa waxaa dheer, qalabku wuxuu leeyahay qiimo aad u xiiso badan oo loogu talagalay sifooyinka farsamada ee lagu dhawaaqay. Kaas oo soo jeedinaya dareenka naftiisa.
Teac UD-301-X USB DAC - dulmar, muuqaalada
UD-301-X waxay ku salaysan tahay laba wareeg oo mono iyadoo la isticmaalayo MUSES8920 J-FET op amps. Iyo labo ka mid ah BurrBrown PCM32 1795-bit digital-to-analog rodol. Habkani wuxuu ka fogaanayaa faragelinta u dhexeeya kanaalada. Intaa waxaa dheer, waxay bixisaa soo noqnoqoshada hodanka ah oo hooseeya oo leh ku-meel-gaar degdeg ah.
Waad ku mahadsan tahay adeegsiga CCLC (Coupling Capacitor Less Circuit) wareegtada, ma jiraan capacitors isku xiran oo hoos u dhigaya codka, kuwaas oo siinaya hoos u dhigista soo noqnoqoshada iyo iswaafajinta wajiga sababtoo ah shaandhaynta. Si loo kordhiyo kartida wax-soo-saarka taleefoonka dhegaha waxa ay saamaxaysaa in la xaddido korontadda soo-saarka xariiqda.
Teac UD-301-X waxay ku qalabaysan tahay koronto tamar tayo fiican leh si ay u siiso hadda deggan qayb kasta oo wareegga ah. Wax-soo-saarka dheelli-tiran ee isbeddelaya (XLR) iyo kuwa aan dheelli-tirnayn (RCA) waxay kuu oggolaanayaan inaad si toos ah ugu xirto cod-weyneeye koronto ama cod-bixiyeyaal firfircoon, haddii loo baahdo.
Habka wareejinta xogta USB asynchronous waxaa lagu hubiyaa saacada gudaha ee saxda ah ee qalabka si loo xakameeyo waqtiga dirida iyo helitaanka xirmooyinka xogta. Tani waxay yaraynaysaa jitter-ka hoos u dhigaya tayada signalka. Iyada oo loo marayo dekedda USB, UD-301-X waxay taageertaa dib-u-soo-celinta Hi-Res ee qaababka PCM 32bit/192kHz iyo DSD128 (Native). Marka la farsameynayo calaamada muunad soo noqnoqota oo ah 96 kHz ama ka hoose, DAC waxay hagaajin kartaa tayada codka. Adigoo u beddelaya calaamadda adigoo kor u qaadaya soo noqnoqoshada sare.
