Singxer SU-6

The SU-6 acts as a high-performance USB digital interface that converts USB audio signals from your computer into various digital formats like S/PDIF, AES/EBU, and I2S for your DAC. It is designed to significantly reduce jitter and improve signal integrity compared to a standard USB connection.

While the unit uses USB for data, it is designed to be powered by an external 7.5V-9V DC power supply. This ensures the internal circuits, including the super capacitor-based power section, receive clean, stable power independent of the noisy USB bus.

The I2S output via HDMI is highly flexible, but there is no universal industry standard for I2S pinouts. You should verify that your DAC's I2S input pin configuration is compatible with the SU-6 settings before connecting.

These femtosecond crystal oscillators provide an ultra-low jitter clock source for the digital signal. By minimizing timing errors, they allow your DAC to reconstruct the audio signal more accurately, resulting in better clarity and soundstage depth.

Yes, the SU-6 supports PCM up to 384KHz and DSD up to DSD512. Please note that these maximum resolutions are primarily achieved through the I2S output, while S/PDIF and AES/EBU connections are limited to 24-bit/192KHz PCM and DSD64 via DoP.

Yes, it is compatible with both operating systems. Windows users will need to install the dedicated XMOS USB driver to enable full functionality and high-resolution support, while Mac users can typically use it plug-and-play.
