This unique product offers both high-performance DAC (digital-analog converter) and DDC (digital-digital converter) solutions, converting the audio signal from the USB Type-C input to the appropriate output. This high-quality, palm-sized, high-performance USB digital/analog audio interface is designed for audiophiles. The AKM4490 DAC ensures superior audio quality, while the single-ended RCA analog output and versatile Type-C input guarantee exceptional sound. The OLED display and multi-functional control wheel provide intuitive control, and the EQ/ATE offers customizable sound profiles. With optical/coaxial and AES/EBU outputs, a high-stability independent clock, and a high-precision phase-locked loop (PLL), it minimizes jitter and supports high-resolution DSD (DoP) audio. Its fully isolated design and metal body enhance shielding and durability, making it an ideal choice for professional-grade audio.
