Teac UD-301-X USB DAC - mwachidule, mawonekedwe
Woyimira mzere wa Reference 301 - Teac UD-301-X USB-DAC amasiyana ndi anzawo mumiyeso yocheperako komanso mawonekedwe otsika. Koma izi sizinakhudze khalidwe lake nkomwe. Kuphatikiza apo, chipangizocho chili ndi mtengo wosangalatsa wazinthu zomwe zanenedwa. Zomwe zimakopa chidwi.
Teac UD-301-X USB DAC - mwachidule, mawonekedwe
UD-301-X idakhazikitsidwa pamagawo awiri a mono wogwiritsa ntchito MUSES8920 J-FET op amps. Ndipo awiri a BurrBrown PCM32 1795-bit digito-to-analogi converters. Njirayi imapewa kusokoneza pakati pa njira. Kuphatikiza apo, imapereka ma frequency otsika otsika okhala ndi ma transients othamanga.
Chifukwa cha kugwiritsa ntchito dera la CCLC (Coupling Capacitor Less Circuit), palibe ma coupling capacitor omwe amatsitsa phokoso, zomwe zimapereka kutsika kwafupipafupi komanso kusagwirizana kwa gawo chifukwa cha kusefa. Kukulitsa kuthekera kwa kutulutsa kwamakutu kumalola kuchepetsa mphamvu yamagetsi pazotulutsa za mzere.
Teac UD-301-X ili ndi chosinthira chamagetsi champhamvu cha toroidal kuti chizitha kukhazikika pagawo lililonse la dera. Zotulutsa zofananira (XLR) ndi zosagwirizana (RCA) zimakulolani kuti mulumikizane mwachindunji ndi amplifier yamagetsi kapena okamba zogwira ntchito, ngati kuli kofunikira.
Ma asynchronous USB data transfer mode amatsimikiziridwa ndi kuwunika kwamkati kwa chipangizocho kuti athe kuwongolera bwino nthawi yotumizira ndi kulandira mapaketi a data. Izi zimapondereza jitter yomwe imawononga mtundu wa chizindikiro. Kudzera padoko la USB, UD-301-X imathandizira kuseweredwa kwa zomwe zili mu Hi-Res mu PCM 32bit/192kHz ndi DSD128 (Native). Mukakonza siginecha yokhala ndi ma frequency a 96 kHz kapena kutsika, DAC imatha kukweza mawu. Mwa kutembenuza chizindikirocho mwa upsampling kupita kufupipafupi.
