Singxer SDA-2

The SDA-2 decoder is a high performance HiFi audio developed by our team. Decoding amp preamplifier XMOS's latest xCORE-200 series chip is adopted as USB Audio solution, AK4497 with AKM third generation DAC is used as DA conversion chip, AK4118 is used as digital audio input receiving chip, STM32 is used as control of whole machine, Xilinx large-scale FPGA Processing as a clock system and digital audio stream. The amp part adopts 4-way full balance design independent discrete class A amp drive circuit; The pre-stage output uses an analog pre-stage design, not a way to affect the digital attenuation of the sound dynamics.; Has a rich input and output interface, including standard USB2.0 input interface, SPDIF coaxial and AES balanced input, analog XLR balanced output, analog RCA output. PCM supports up to 384Khz, DSD uses native direct solution technology, the highest supportDSD512, all interfaces support DSD decoding. DAC chip uses AKM\'s flagship DAC AK4497EQ; DSD adopts
