It uses XMOS’ latest xCORE-200 series chip XU208 as the USB Audio solution, and uses AKM’s third-generation flagship DAC: AK4499 as the main chip for digital-to-analog conversion, AK4118 As a digital audio input receiving chip, STM32 is used as the control core of the whole machine, and Xilinx's large-scale FPGA is used as a clock system and digital audio stream processing. PCM supports up to 384Khz, DSD adopts native direct solution technology, and supports up to DSD512.\u003cbr\u003e\u003cbr\u003e The DAC chip adopts the latest AK4499 released by AKM in 2019; DSD adopts the native direct solution mode, and the DSD digital stream does not pass through the internal digital filter and works in the NOS mode, which fully conforms to the design concept of HQPlayer.\u003cbr\u003e\u003cbr\u003e It has a wealth of input and output interfaces, including standard USB2.0 input interface, SPDIF and BNC coaxial and AES balanced input, HDMI-I2S input interface, analog output including XLR balanced output and RCA single-ended output; all interfaces support DSD input.\u003cbr\u003e\u003cbr\u003e SDA-6 supports external clock input, among which USB supports 10M clock input, and other interfaces support WCK input. In USB mode, it also supports a switchable input impedance of 50 and 75 ohms\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cimg align=\"absmiddle\" src=\"https:\/\/img.alicdn.com\/imgextra\/i3\/17455497\/O1CN01kd1nfL1qTfmviZkwe_!!17455497.jpg\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cstrong\u003eTechnical Specification: \u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli style=\"text-align: left;\"\u003eSelf-developed adaptive clock system technology, built-in 4 independent ultra-low jitter audio crystal oscillators, equipped with a femtosecond-level local clock system for the USB part, the standard version of the crystal oscillator is AS-318B, and the high version is CCHD- 957.\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eHigh-performance digital-analog hybrid phase-locked loop, excellent clock synchronization recovery technology, can greatly filter the secondary PLL of the external digital input jitter;\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eIt adopts 4 channels of fully balanced and full DC discrete circuit output;
