PRODUCT FEATURES

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 the original direct solution mode. The DSD digital stream does not pass through the internal digital filter and modulator. It works in NOS mode. PCM can also choose to work in NOS mode, which is in line with HQPlayer design.

SDA-2 is the first decoding amp preamp product we developed, mainly using the following four main technologies:

1, USB part uses our first generation isolation technology: SCIT technology (Singxer capacitor isolation technique), SCIT technology is a full isolation technology (ground isolation), high-speed signal using 150Mbps isolation chip, low-speed signal using optocoupler isolation , can completely isolate interference from PC; The high-end version of the USB part can basically reach the level of the SU-1 independent digital interface.

2, source synchronization technology and FPGA shaping technology, reshaping the isolated I2S signal; Thereby eliminating the additive jitter caused by the isolation chip;

3, self-developed clock system, using femtosecond crystal as the local reference clock;

4, 4-way class A discrete amp circuit, full balanced amplification of 8 patch transistors per route.
