Supports the highest sampling rate and tested PCM384KHZ to work normally, and does not support DSD format.
Output: Single-ended (RCA) L-OUT and R-OUT
Balanced (XLR) XLR L +/- and XLR R +/-
Output analog signal level: single-ended 2.5vRMS
Balanced 4.8vRMS
The entire decoder board uses CPLD as data processing. The advantage is that CPLD is parallel processing, not serial processing like peripheral logic chips, and the delay between all gates will accumulate. The delay to the last data is very large. The resulting signal jitter cannot be ignored. Therefore, the R2R DAC developed by CPLD has advantages.
This decoder board has mid-tone accuracy, deep bass diving, and high-tone accuracy. The overall experience shows that the degree of separation is better than that of the integrated IC solution. (Under the premise of cooperating with our USB interface card)
This board manufactured by SMT industrialization, the components are neat and beautiful, and the solder joints are full and shiny. The use of SMT production reduces manual reclaiming and avoids soldering wrong components. Greatly improve the accuracy and precision of decoding. Escort for the good voice. In terms of price, it is deeply rooted in the hearts of the people. At a price close to the people, enthusiasts can enjoy the treatment of large-scale machinery.
