HiFi Finished L1541 Audio DAC Digital Coaxial Fiber CM6631 USB TDA1541 Decoder

Description: Details:Including TDA1541 chipsUsing CM6631 24Bit 192K USB asynchronous subcard.Replace SAA7220 chip with L7220Tran.（The completion of the L7220Tran chip is very good, and it is not much different from the original SAA7220P/B chip. You can replace it with the SAA7220P/B chip yourself, but in our opinion, the significance of replacing this chip is not significant.）Power supply: Four high-quality sealed transformers are used to strictly distinguish between digital power supply, decoding chip power supply, and LPF power supply. For the TDA1541 chip, two transformers are used for the two negative voltages (-5V, -15V), avoiding cross interference caused by introducing -15V from the LPF power supply circuit!MCU soft control digital reception: The microcomputer dynamically optimizes parameters and adjusts the phase detector of the receiving chip (CS8416) to automatically adapt to the input bit rate, minimizing jitter.Carefully designed second-order LPF circuit: This decoding uses four single operational amplifiers to complete the second-order LPF low-pass circuit, which is a very important design, ensuring its driving ability and LPF circuit characteristics.CNC precision machining aluminum chassis, high-end wire drawing and oxidation process.Supports macOS and most Linux systems Specifications:Digital input: coaxial, fiber, USBAnalog output: RCA analog output.Digital input bit rate: 16bit, 44.1K, 48K.Analog output level: 2Vrms.Power supply: AC110V or AC220V.
