Topping D30 Pro Quad CS43198 DAC Hi-Res Decoder - Black

Powerful 4 x CS43198 DAC Chips What changes can a quad DAC brings? The answer is in TOPPING newly launched D30 PRO. With the use of 4*CS43198 chips, it provides a total of 8 full balanced channels, each of which is arranged in parallel by 4 conventional balanced channels. Optical/Coaxial/USB Inputs, RCA/XLR Output D30 Pro support USB/ Coaxial/ Optical inputs, USB maximum support PCM 32bit/ 384kHz, DSD256 (Native), DSD128 (Dop); D30pro has full balanced XLR output and single ended RCA output. You can choose XLR only, #34;RCA only #34; or XLR+RCA output to meet different usage in the multiple systems. Preamplifier Function D30 pro has preamplifier function so you can control the output volume on the front panel or use remote control. Its noise is lower than other similar products making it suitable for connecting to power amplifiers or monitor speakers while also help you leave the budget of a preamp. What Effort Weve Made CPLD focusing on clock processing and digital signal optimization, restoring what t he digital signal should be. We use up to 8 independent LDOs to supply power to different loads, so there is no longer interference between different loads. Both RCA and XLR have reached the 120dB SINAD, so that RCA transmission can also have same excellent performance as XLR.
