USB Digital Interface: Superior Signal Conversion

The USB digital interface transforms digital audio signals from USB sources into traditional outputs like coaxial or optical, enabling seamless connection to a decoder. This process reduces power noise, electromagnetic interference, timing errors, and interface distortion, resulting in enhanced audio fidelity and sound quality.

Compact Design: Lightweight and Portable

Equipped with XMoS chips for asynchronous transmission, this mini USB digital interface ensures high-quality signal processing. Featuring a Type-C USB input for modern compatibility, it comes in a pocket-sized form factor, weighing only 75g (including packaging), making it ideal for on-the-go use.

Versatile Outputs and Advanced Clock Technology

This device supports optical and coaxial digital outputs with sampling rates from 44.1kHz to 192kHz and DOP64 (DSD64). Combined with the XMOS chip and SMSL's CK-02 clock circuit design, it delivers ultra-low clock jitter and pristine audio clarity.

XMOS XU316 and MQA Decoding

Powered by the 3rd generation XMOS XU316 chip, this interface supports MQA decoding for master-quality sound. MQA playback doesn’t require specialized software like foobar2000 or Audirvana Plus; simply use ASIO or WASAPI-compatible audio outputs for optimal results.

Plug and Play: Effortless Compatibility

No drivers are needed for macOS or Windows 10 and above—just connect to your PC, phone, or tablet, and the device will appear as "SMSL USB AUDIO" in the system's audio settings. For Windows 10 and earlier versions, driver installation is required.

Broad Device Compatibility

Compatible with computers, mobile phones, tablets, and players/streamers with USB output, the device supports Android, iOS, PC, and tablet systems. For gaming consoles, consider upgrading to the PO100PRO.

Simplified Use of DOP64

To enable DOP64, set the player software to DOP output mode and connect via optical or coaxial to a DOP64-compatible DAC. Note that Windows systems require driver installation for DOP playback.
