Details: Warm Tips:
1. Without a DC 5V power adapter, please prepare a high-quality original power adapter (DC 5V ≥1A) yourself. Note: Input voltage above 5V will cause damage.
2. The U3 PRO will not work well if the power adapter current is less than 1A.
3. The 3.5mm and 6.35mm headphone jacks can output simultaneously. Please do not use the RCA and AUX inputs at the same time, otherwise the sound will be mixed.
