I-Teac UD-301-X USB DAC - uhlolojikelele, izici
Ummeleli womugqa we-Reference 301 - i-Teac UD-301-X USB-DAC ihlukile kozakwabo ngobukhulu obuncishisiwe kanye nephrofayili ephansi. Kodwa lokhu akuzange kuthinte ikhwalithi yayo nhlobo. Ngaphezu kwalokho, idivayisi inenani elithakazelisayo lezimpawu zobuchwepheshe ezimenyezelwe. Okudonsela ukunaka kuyona.
I-Teac UD-301-X USB DAC - uhlolojikelele, izici
I-UD-301-X isuselwe kusekethe ye-mono ekabili esebenzisa ama-op amps e-MUSES8920 J-FET. Futhi ipheya yeziguquli ze-BurrBrown PCM32 1795-bit digital-to-analog. Le ndlela igwema ukuphazamiseka phakathi kwamashaneli. Futhi, iletha amaza aphansi acebile anama-transient asheshayo.
Ngenxa yokusetshenziswa kwesifunda se-CCLC (Coupling Capacitor Less Circuit), awekho ama-coupling capacitor alulaza umsindo, okunikeza ukuncishiswa kwe-low-frequency kanye nokungafani kwesigaba ngenxa yokuhlunga. Ukwandisa amandla okukhipha ama-headphone kuvumela ukukhawulela ukunikezwa kwamandla kokuphumayo kolayini.
I-Teac UD-301-X ifakwe isiguquli samandla e-toroidal esisebenza kahle ukuze sinikeze amandla amanje azinzile kuyo yonke ingxenye yesekethe. Okuphumayo kwe-variable balanced (XLR) nokungalingani (RCA) kukuvumela ukuthi uxhume ngokuqondile kusikhulisi samandla noma izipikha ezisebenzayo, uma kudingeka.
Imodi yokudlulisa idatha ye-USB engavumelanisiwe iqinisekiswa ngokufakwa kwewashi okunembayo kwangaphakathi kocingo ukuze kulawulwe kahle isikhathi sokuthumela nokwamukela amaphakethe edatha. Lokhu kucindezela i-jitter eyehlisa ikhwalithi yesignali. Ngembobo ye-USB, i-UD-301-X isekela ukudlalwa kokuqukethwe kwe-Hi-Res kumafomethi e-PCM 32bit/192kHz kanye ne-DSD128 (Yendabuko). Lapho icubungula isignali enemvamisa yesampula engu-96 kHz noma ngaphansi, i-DAC ingathuthukisa ikhwalithi yomsindo. Ngokuguqula isignali ngokunyusa isampula iye kwifrikhwensi ephezulu.
