DAC / Preamp Topping D30PRO
Topping D30Pro yog digital-rau-analog converter nrog preamp hauv ib chav. Cov khoom siv suab muaj ob qhov tso tawm nrog qhov ua tau ntawm cov teeb liab sib npaug. Cov khoom siv hluav taws xob hauv MeanWell tau muab, ua haujlwm ntawm qhov hluav taws xob input ntawm 110-240V.
Topping D30PRO DAC/Preamplifier Txheej txheem cej luam
Hauv cov qauv no, Topping tau tso tseg kev siv AKM thiab ESS chips. Hloov chaw, kuv siv ob khub ntawm CS43198 chips los ntawm Cirrus Logic. Qhov tshwm sim yog qhov kev siv ntawm cov tswv yim sib npaug. Ua tsaug rau tag nrho-fledged 8 raws kev khiav hauj lwm nyob rau hauv parallel, nws yog ua tau kom tau txais kev kawm siab. Nws zoo li no:
- THD: tsis ntau tshaj 0.0001% (1kHz).
- Teeb liab rau lub suab nrov piv: kwv yees li 120 dB (1kHz).
- Dynamic Range: 128dB (1kHz)
Cov cuab yeej muaj qhov tso zis hluav taws xob ntawm 2Vrms thiab 4Vrms rau cov zis tsis sib npaug thiab sib npaug. Raws li cov suab nrov qis, uas tsawg dua 0.9uVrms thiab 1.1uVrms. Cov kev ntsuas no zoo kawg nkaus tus yam ntxwv ntawm D30Pro ua lub preamplifier. nquag acoustics.
Qhov zoo ntawm Topping D30PRO
Ib qho ntawm qhov zoo ntawm D30Pro yog qhov muaj CPLD. Nws yog programmable logic integrated circuit. Nws lub hom phiaj yog los tawm tsam jitters los ntawm kev ua cov moos pulses thiab tom qab ntawd optimizing lub teeb liab. Qhov kev ua tau zoo ntawm cov tshuaj no tau lees paub ob qho tib si los ntawm cov neeg tsim khoom ntawm cov cuab yeej thiab los ntawm cov kws tshaj lij ywj pheej.
Kev sib txuas USB yog muab los ntawm XMOS maub los qauv XU208. Nws muaj kev cai Thesycon tsav tsheb, txhawb Hi-Res (PCM 32bit / 384kHz thiab DSD256) thiab ASIO. Windows 7 (thiab saum toj no) thiab macOS systems tsis tas yuav nruab tus tsav tsheb. Ntawd yog, lawv tuaj yeem ua haujlwm ntawm lub hauv paus ntsiab lus ntawm Plug thiab Ua Si.
Cov chaw taws teeb tswj uas suav nrog tso cai rau koj tsis tsuas yog kho lub ntim, tab sis kuj xaiv cov tswv yim nquag thiab tso tawm. Qhov no yooj yim heev thaum txuas ntau yam khoom siv rau D30Pro.
