1、1. Adopt original PCM5100 and MS8416. 2、2. The resistor uses a five-ring metal resistor, and the main circuit uses a five-ring metal film resistor with an accuracy of ±1% to ensure a good signal-to-noise ratio. 3、3. Coupling capacitor adopts chip capacitor, main filter electrolytic capacitor adopts capacity 2200UF/25V, ensuring strong and continuous power support. 4、4. PCB uses 1.6mm thick double-sided sheet, 2.0 oz copper thickness, spray tin process, to ensure good passing performance of large and small current. 5、5. Optical fiber input support to 96KHZ, USB support 48K (computer does not need to install driver). Features: 1. Adopt original PCM5100 and MS8416. 2.
