DAC / Preamp Topping D30PRO
I-Topping D30Pro yi-digital-to-analog converter ene-preamp kwiyunithi enye. Izixhobo zomsindo zineziphumo ezimbini ezinokubakho kophawu oluhambelanayo. Unikezelo lwangaphakathi lwangaphakathi lweMeanWell lunikezelwa, lusebenza kwi-voltage yegalelo ye-110-240V.
I-Topping D30PRO DAC/Preamplifier Overview
Kulo mzekelo, i-Topping iyekile ukusetyenziswa kwee-chips ze-AKM kunye ne-ESS. Endaweni yoko, ndisebenzise iperi ezimbini zeetshiphusi zeCS43198 ezivela kwiCirrus Logic. Isiphumo kukuphunyezwa kwesikimu esilungelelanisiweyo. Ngombulelo kwiitshaneli ezipheleleyo ezi-8 ezisebenza ngokufanayo, kwakunokwenzeka ukufumana ukusebenza okuphezulu. Ijongeka ngolu hlobo:
- I-THD: akukho ngaphezu kwe-0.0001% (1kHz).
- Ubungakanani bomqondiso kwingxolo: malunga ne-120 dB (1kHz).
- Uluhlu oluDynamic: 128dB (1kHz)
Isixhobo sinomthamo we-voltage ye-2Vrms kunye ne-4Vrms yemveliso engalinganiyo kunye nokulinganisela ngokulandelanayo. Kunye nenqanaba lengxolo eliphantsi, elingaphantsi kwe-0.9uVrms kunye ne-1.1uVrms. Ezi parameters zibonisa ngokugqibeleleyo i-D30Pro njenge-preamplifier. iacoustics esebenzayo.
Izinto ezilungileyo ze-Topping D30PRO
Enye yeenzuzo eziphambili ze-D30Pro kubukho be-CPLD. Yisekethe edibeneyo yengqiqo ecwangcisekileyo. Injongo yayo kukulwa i-jitter ngokucubungula i-clock pulses kwaye emva koko ulungelelanisa umqondiso. Ukusebenza kwesi sisombululo kuye kwaqinisekiswa ngabaphuhlisi besixhobo kunye neengcali ezizimeleyo.
Uqhagamshelo lwe-USB lubonelelwa ngemodeli yesilawuli seXMOS XU208. Inomqhubi we-Thesycon yesiko, isekela i-Hi-Res (PCM 32bit / 384kHz kunye neDSD256) kunye ne-ASIO. Windows 7 (nangaphezulu) kunye neenkqubo ze-macOS azidingi kufakela umqhubi. Oko kukuthi, banokusebenza kumgaqo wePlug kunye nokuDlala.
Ulawulo olukude olubandakanyiweyo lukuvumela ukuba ungalungiseleli kuphela umthamo, kodwa ukhethe kwakhona igalelo elisebenzayo kunye nemveliso. Oku kulula kakhulu xa uqhagamshela izixhobo ezininzi kwi-D30Pro.
