Nobsound U2 Compact USB Digital Interface

【High-Quality Sound Transmission】Lossless Conversion with XMOS XU316 Chip: Converts USB input signals to optical and coaxial SPDIF signals for transmission to DACs, digital amplifiers, and home theater systems. Through high-precision clock design and processing by the XMOS XU316 chip, it supports 44.1kHz to 192kHz/24bit PCM and DSD64 (DoP) formats. It reduces jitter (timing fluctuations) and outputs digital signals faithful to the original sound. Unlike analog connections, which are susceptible to noise, it achieves clear sound reproduction by leveraging the characteristics of digital transmission paths. Ideal for expanding sound source input for audio file systems.
【Multi-Device Connection】Flexible System Integration for PC/Smartphone/Tablet: Compatible with a wide range of OS including Windows 10/11, macOS, Android, iOS (requires accessories), and Linux. The included USB-C to USB-A/C cable allows direct connection to PCs with Type-A ports and the latest smartphones/tablets with Type-C ports. OTG function support allows immediate operation as a USB-DAC on Android smartphones.
【Reduced Installation Burden】Driverless Operation & Compact Design: No driver required for PCM playback on major OS (※Driver required for DSD playback and Windows 7/8). Easy to use immediately upon connection. The chassis size is only 40x52x20mm (smaller than a business card), with an ultra-lightweight design of 45g. It doesn't get in the way even when placed directly on top of a DAC or amplifier, and doesn't take up space on your desk or rack. USB bus power eliminates the need for additional wiring. Prevents system complexity with a simple configuration.
【Operation Confirmation Support】Real-time Sampling Rate Display Function: The LED indicator on the front of the unit displays the current audio format (PCM/DSD) and sampling rate (44.1k/48k/96k/192k, etc.) in real-time. You can visually confirm whether the output settings of the player software are correctly reflected, solving concerns such as "Uncertain if the playback format is correct" and "Unsure if bit-perfect playback is possible." It can also be used as a simple diagnostic tool for connection troubles.
