Singxer SDA-6 (SDA6, SDA 6) Advanced DAC DSD512 AK4499 XMOS XU208 DAC Decoder

SDA-6 is a high-performance DAC developed by our Singxer team. 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 the clock system and digital audio stream processing.


> Self-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.

> High-performance digital-analog hybrid phase-locked loop, excellent clock synchronization recovery technology, can greatly filter the secondary PLL of external digital input jitter.

> It adopts 4 channels of fully balanced and full DC discrete circuit output; among them, the high-end version adopts non-loop negative feedback output.

> Large-scale FPGA for digital audio signal processing, self-developed second-generation algorithm, original multi-input channel isolation technology, to ensure the purity of each input signal.

> Built-in 40 watt custom O-type transformer, output 4 independent power supply windings, up to 20 groups of distributed voltage stabilized circuits; among them, the reference power supply for AK4499 is the newly developed super low noise (as low as 0.5uV RMS) power supply system.


> Output impedance: 22 ohms (RCA single-ended) / 45 ohms (XLR balanced)
> Frequency response: 20-20kHz +/-0.1dB
> S/N ratio: 131dB (20-22kHz A weighting)
> Distortion characteristics:
> THD+N (1kHz, 0dBFS) 0.00012% (-118db) at fs=44.1Khz (PCM, 20Hz-22kHz A weighting))
> Dynamic response (1kHz, -60dBFS) 131dB (20Hz-22kHz A weighting)
> Left and right channel separation >130dB @1kHz
