Teac UD-301-X USB DAC - amagqabantshintshi, iimpawu
Ummeli we-Reference 301 line - i-Teac UD-301-X USB-DAC ihluke kubalingani bayo kwimilinganiselo encitshisiweyo kunye neprofayili ephantsi. Kodwa oku akuzange kuchaphazele umgangatho wayo konke konke. Ukongeza, isixhobo sinexabiso elinomdla kakhulu kwiimpawu zobugcisa ezichaziweyo. Etsalela ingqalelo kuyo.
Teac UD-301-X USB DAC - amagqabantshintshi, iimpawu
I-UD-301-X isekwe kwisekethe ye-mono ezimbini kusetyenziswa i-MUSES8920 J-FET op-amps. Kwaye iperi BurrBrown PCM32 1795-bit digital-to-analog converters. Le ndlela ithintela ukuphazamiseka phakathi kwamajelo. Ukongeza, ibonelela ngee-frequencies ezityebileyo eziphantsi kunye nee-transients ezikhawulezayo.
Ndiyabulela ekusebenziseni i-CCLC (i-Coupling Capacitor Less Circuit) yesiphaluka, akukho zi-capacitors ezidibanisayo ezithobisa isandi, ezinika ukuthotywa kwe-low-frequency attenuation kunye nesigaba sokungalingani ngenxa yokucoca. Ukwandisa amandla emveliso ye-headphone kuvumela ukunciphisa unikezelo lwamandla kwiziphumo zomgca.
I-Teac UD-301-X ixhotyiswe nge-transformer yamandla e-toroidal esebenzayo ukubonelela ngoku uzinzile kuyo yonke indawo yesekethe. I-variable balanced (XLR) kunye neziphumo ezingalinganiyo (RCA) zivumela ukuba udibanise ngokuthe ngqo kwi-amplifier yamandla okanye izithethi ezisebenzayo, ukuba kuyimfuneko.
Imowudi yokudlulisa idatha ye-USB engahambelaniyo iqinisekiswa ngokuvalwa okuchanekileyo kwangaphakathi kwesixhobo ukulawula ngokuchanekileyo ixesha lokuthumela nokufumana iipakethi zedatha. Oku kucinezela ijitha ethoba umgangatho wophawu. Ngechweba le-USB, i-UD-301-X ixhasa ukudlalwa kwakhona komxholo we-Hi-Res kwi-PCM 32bit/192kHz kunye neefomathi ze-DSD128 (Native). Xa kusetyenzwa isignali ngesampulu yesampulu ye-96 kHz okanye esezantsi, i-DAC inokuphucula umgangatho wesandi. Ngokuguqula umqondiso ngokunyusa isampuli ukuya kwifrikhwensi ephezulu.
