DAC/Preamp Topping D30PRO
Topping D30Pro ndi chosinthira digito-to-analogi chokhala ndi preamp mugawo limodzi. Zida zomvera zimakhala ndi zotulutsa ziwiri ndi kuthekera kotulutsa ma siginecha ofanana. Mphamvu yamkati ya MeanWell imaperekedwa, ikugwira ntchito pamagetsi olowera a 110-240V.
Kuwongolera mwachidule kwa D30PRO DAC/Preamplifier
Muchitsanzo ichi, Topping wasiya kugwiritsa ntchito tchipisi ta AKM ndi ESS. M'malo mwake, ndidagwiritsa ntchito ma tchipisi awiri a CS43198 ochokera ku Cirrus Logic. Chotsatira chake ndi kukhazikitsidwa kwa ndondomeko yoyenera. Chifukwa cha mayendedwe athunthu 8 omwe amagwira ntchito limodzi, zinali zotheka kupeza magwiridwe antchito apamwamba. Zikuwoneka motere:
- THD: osapitirira 0.0001% (1kHz).
- Chiyerekezo cha Signal to Phokoso: pafupifupi 120 dB (1kHz).
- Dynamic Range: 128dB (1kHz)
Chipangizocho chili ndi mphamvu yotulutsa 2Vrms ndi 4Vrms kuti ikhale yosagwirizana komanso yokwanira motsatana. Komanso phokoso laling'ono, lomwe ndi locheperapo 0.9uVrms ndi 1.1uVrms. Magawo awa amawonetsa bwino D30Pro ngati chowongolera. ma acoustics yogwira.
Ubwino wa Topping D30PRO
Ubwino umodzi waukulu wa D30Pro ndi kupezeka kwa CPLD. Ndi pulogalamu yokhazikika yolumikizirana ndi logic. Cholinga chake ndikulimbana ndi jitter pokonza mawotchi a wotchi ndikuwongolera chizindikiro. Kuchita bwino kwa yankholi kwatsimikiziridwa ndi omwe akupanga chipangizochi komanso akatswiri odziimira okha.
Kulumikizana kwa USB kumaperekedwa ndi XMOS controller model XU208. Ili ndi dalaivala wa Thesycon, imathandizira Hi-Res (PCM 32bit / 384kHz ndi DSD256) ndi ASIO. Windows 7 (ndi pamwambapa) ndi machitidwe a macOS safunikira kukhazikitsa dalaivala. Ndiko kuti, amatha kugwira ntchito pa mfundo ya Pulagi ndi Sewerani.
Kuwongolera kwakutali komwe kumaphatikizidwa kumakupatsani mwayi kuti musamangosintha voliyumu, komanso sankhani zomwe zimagwira komanso zotulutsa. Izi ndizothandiza kwambiri polumikiza zida zingapo ku D30Pro.
