Warm tips
1.The U2 PRO supports OTG and comes with an OTG-compatible USB cable for direct connection to OTG-enabled phones. For iPhones or iPads with a Lightning port, a high-current camera kit is required. Newer models with a Type-C port can use the included cable directly.
2. The U2 PRO supports oscillator replacement (not pluggable, needs soldering). To replace the U2 PRO's oscillator, it needs to meet these specs: 24.000MHz/1.8-3.3V (active oscillator) Can be SMD or through-hole (DIP) SMD size: 5032 DIP spec: DIP14 The smaller the frequency tolerance (+ppm), the better. *We also tested fixed 3.3V oscillator, it can work normally as well. However, we can't guarantee that every voltage within the 3.3–5V range will work. Rest assured, an incompatible oscillator will not damage the U2 PRO, it may simply not function.
3. The U2 PRO only supports 2.0 channel stereo audio. Multichannel formats such as 5.1, 7.1, or Dolby formats are not supported.
4. Please install the required driver and files from the included USB drive, and follow the instructions or video guide to set up your player properly.
