Figure 1-3
After upgrading from MK2 to MK3, the upscaling function has been added.(Can be turned on or off via the remote control Program key), Upgrade the internal clock to the OCXO temperature-compensated crystal oscillator and make corresponding adjustments. The internal solder uses Kadas to make the sound warmer and more charming.

Jay''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s Audio DAC-2 is a high-performance DAC audio decoder developed after two years. The USB part uses the latest XU208 from XMOS as the USB Audio solution, and the DAC core is the flagship level of AKM: dual AK4497EQ As the main chip of digital-to-analog conversion, AK4118 ultra-low jitter is used as the 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 the clock system and digital audio stream processing. PCM supports up to 384Khz, DSD adopts native direct solution technology, DSD digital stream does not pass through the internal digital filter, works in NOS mode, fully conforms to the design idea of ??HD Player, and can support DSD512 after firmware upgrade.
Technical features:
1. Self-developed adaptive clock system technology, built-in 4 independent ultra-low jitter audio crystal oscillators, and configures the US CRYSTEK femtosecond local clock system for the USB part
2. High-performance digital-analog hybrid phase-locked loop, excellent clock synchronization recovery technology, can greatly filter the secondary PLL of the external digital input jitter;
3. Source synchronization technology and FPGA shaping technology, to reshape the isolated I2S signal, thereby eliminating the additive jitter caused by the isolation chip;
4. Large-scale FPGA for digital audio signal processing, self-developed algorithms, and original multi-input channel isolation technology to ensure the purity of each input signal.
5. Two European imported high-grade toroidal transformers and multiple sets of super low phase noise regulated power supplies are used to provide independent power supply for USB, digital input, DAC core part, and analog output.

Interface standard:
1. The USB input socket is a standard USB-B type female socket, and the USB power supply range is 4.5V-5.1V;
2. The SPDIF interface inputs standard S/PDIF signals, the input impedance is 75 ohms, and the AES input impedance is 110 ohms;
3. The I2S input is LVDS 3.3v differential level in the form of HDMI interface, compatible with the SU-1 interface; it can be configured to be compatible with different turntables through the internal DIP switch. The difference between the standard version and the signature version of the IIS interface: The SE signature version uses a special adjustment The materials used for calibration include the expensive British AUDIO NOTE, AMTRANS capacitors, HOCLO resistors, Campbell internal cables, and Furukawa rhodium-plated power sockets.
