Features:

1.The advanced version adopts loop-free negative feedback full-direct current full-balance discrete class a output circuit the USB part uses CCHD-957 femtosecond clock and the analog part uses Mundorf film capacitor to tune; It's a little looser on the vocal a little more alive.

2.SDA-6 is a high-performance DACwhich adopts XMOS latest xCORE-200 series chip XU208 as the USB Audio scheme AKM's third generation flagship DAC: AK4499 as the main digital-to-analog conversion chip AK4118 as the digital Audio input reception chip using STM32 as the control core Xilinx's large-scale FPGA as the clock system and digital audio stream processing. PCM supports up to 384 Khz DSD adopts native direct solution technology and supports up to DSD512.

3.DAC chip using AKM in 2019 the latest release of AK4499; DSD using native direct solution mode DSD digital flow without internal digital filter work in NOS mode fully in line with the design of HQPlayer.

4.It has a wide range of input and output interfaces including the standard USB2.0 input interface SPDIF with BNC coaxial and AES balanced input HDMI-I2S input interface analog output including XLR balanced output and R single-ended output;and full interface support for DSD input.

5.SDA-6 supports external clock input where USB supports 10M clock input and other interfaces support WCK input. In USB mode it also supports 50¦¸ and 75¦¸ switchable input impedances.

6.Self-developed adaptive clock system technology built-in 4 independent ultra-low jitter audio crystalfor the USB part of the configuration of femtosecond-level local clock system the standard version of the crystal oscillatoris is AS-318B the advanced version of the crystal oscillatoris is CCHD-957.

7.High performance digital-analog Hybrid PLL(Phase-Locked Loop) excellent clock synchronization recovery technology can greatly filter external digital input Jitter Secondary PLL;

8.It adopts 4-way full-balanced full-direct current Class A discrete circuit output in which the advanced version adopts loop-free negative feedback output;

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

10.Built-in 40W custom type O transformeroutputs 4 independent power supply windings up to 20 distributed voltage stabilizing lines; the reference power supply for AK4499 is a newly developed super low noise (as low as 0.5 uV RMS) power supply system.
