I-DAC/Preamp Topping D30PRO
I-Topping D30Pro isiguquli sedijithali-kuya-analogi esine-preamp kuyunithi eyodwa. Imishini yomsindo inemiphumela emibili enethuba lokukhipha isignali efanayo. Ukunikezwa kwamandla kwangaphakathi kwe-MeanWell kunikezwa, kusebenza ku-voltage yokufaka engu-110-240V.
I-Topping D30PRO DAC/Preamplifier Uhlolojikelele
Kule modeli, i-Topping ikuyekile ukusetshenziswa kwama-chips e-AKM ne-ESS. Esikhundleni salokho, ngisebenzise amapheya amabili e-CS43198 chips ku-Cirrus Logic. Umphumela uba ukuqaliswa kohlelo olulinganayo. Ngenxa yeziteshi ezigcwele eziyi-8 ezisebenza ngokufana, bekungenzeka ukuthola ukusebenza okuphezulu. Kubukeka kanjena:
- I-THD: akukho ngaphezu kuka-0.0001% (1kHz).
- Isilinganiso sesignali kumsindo: cishe 120 dB (1kHz).
- Ibanga elinamandla: 128dB (1kHz)
Idivayisi ine-voltage ephumayo engu-2Vrms kanye ne-4Vrms okukhiphayo okungalingani futhi okulinganayo ngokulandelanayo. Kanye nomsindo ophansi, ongaphansi kuka-0.9uVrms no-1.1uVrms. Lawa mapharamitha akhombisa kahle i-D30Pro njenge-preamplifier. ama-acoustics asebenzayo.
Izinzuzo ze-Topping D30PRO
Enye yezinzuzo ezinkulu ze-D30Pro ubukhona be-CPLD. Kuyisekethi edidiyelwe ye-logic ehlelekayo. Umgomo wayo ukulwa ne-jitter ngokucubungula ama-pulses wewashi bese uthuthukisa isignali. Ukusebenza kwalesi sixazululo kuqinisekiswe kokubili ngabathuthukisi bedivayisi kanye nochwepheshe abazimele.
Uxhumano lwe-USB luhlinzekwa imodeli yesilawuli se-XU208. Inomshayeli we-Thesycon ngokwezifiso, isekela i-Hi-Res (PCM 32bit/384kHz ne-DSD256) ne-ASIO. Windows 7 (nangaphezulu) nezinhlelo ze-macOS azidingi ukufaka umshayeli. Okusho ukuthi, bangasebenza kumgomo we-Plug and Play.
Isilawuli kude esifakiwe sikuvumela ukuthi ungagcini ngokulungisa ivolumu, kodwa futhi ukhethe okokufaka okusebenzayo nokukhiphayo. Lokhu kulula kakhulu uma uxhuma amadivaysi amaningi ku-D30Pro.
