Singxer SDA-6 Pro 2 is the latest flagship DAC developed with AKM’s new-generation AK4191+dual AK4499EX DAC chips and a custom-developed FPGA signal processing architecture. Singxer has optimized the internals of the SDA-6 Pro 2 to achieve class-leading performance promising quality output with ultra-low distortion and high SNR performance. The SDA6 Pro 2 supports native DSD and 32-bit PCM audio signals!!

New-Generation AKM DAC Chipset:-

Enjoy amazing sound signal decoding performance with a rich, velvety AKM in-house sound. The Singxer SDA6 Pro 2 comes equipped with a new-gen AK4191+Dual AK4499EX DAC chipset. This dual DAC arrangement delivers quality output by providing a natural tone, exquisite details, ultra-clear background, and low distortion performance. The output has amazing dynamics and high SNR performance.

Upgraded XMOS USB Processor Chipset:-

Singxer has upgraded the USB processor chip on the SDA6 Pro 2. It now comes with an XMOS XU316 16-core 3rd generation processor that enables smooth sound signal processing supporting up to 32-bit/76kHz PCM and native DSD512 audio signals. The SDA 6 Pro 2 is a true flagship-level performer in terms of USB Processing and overall performance.

Specially Developed Large-Scale FPGA Architecture:-

In order to achieve smooth digital audio signal processing, SDA-6 Pro 2 features a specially optimized FPGA architecture. It adopts self-developed third-gen algorithms with original multi-input channel isolation technology to ensure the purity of each input mode. Singxer SDA-6 Pro 2 features a high-performance digital-analog hybrid Phase-Locked Loop, that provides excellent clock synchronization recovery technology. It significantly improves the performance by filtering external digital input jitter secondary PLL.

Self-Developed Low-Jitter Clock Architecture:-

Singxer SDA-6 Pro 2 features a self-developed adaptive clock system technology. The DAC has a built-in 4-way independent ultra-low jitter crystal that is configured using a femtosecond clock system for the USB part. The clock architecture is embedded with Singxer’s self-developed thermostat technology to maintain a constant temperature. The SDA-6 Pro 2 also supports external 10M clock input for the USB interface while the other interfaces use WCK input.

Consistent Performance With Premium Power Supply:-

Singxer has a built-in 40-watt customized O-type transformer. The output of the four independent power supply winds up to 20 groups of distributed voltage regulator lines. Both the digital and the analog sections get a proper supply of power ensuring consistent performance in any given scenario.
