Digital ES9038Q2M Hifi DAC Decoder Rectifier Amplifier Board USB Audio JRC5532 3900UF/16V 96KHZ Coaxial Optical Output RCA The original ES9038Q2M and JRC5532 are used, and the USB uses a customized security decoding chip. The resistance is made of five-ring metal resistor, and the main circuit is made of five-ring metal film resistor with accuracy of 1%, which ensures the good signal-to-noise ratio of the whole machine. The coupling capacitor adopts the chip imported capacitor, the main filter electrolytic capacitor adopts Nikon name, the capacity is 3900UF/16V, to ensure the strong and continuous power support. The PCB adopts 1.6mm thick double-sided plate, 2.0 Oz copper thickness, and the whole process of tin spraying to ensure the good passing performance of large and small currents. Optical fiber input support up to 96KHZ, USB support 48K(PC comes with a driver does not need to install a driver) Basic parameters: Power supply voltage: DC12V 2A (5.5*2.1 interface) PCB size: 144*83MM Products include: 1X Decoder board _x000D_
