Douk Audio U3 PRO - 1500mW 18-600Ω 3.5mm & 6.35mm

Warm Tips: 1. Without DC 5V power adapter, please prepare an original high-quality power adapter yourself (DC 5V ≥1A). Note: the input voltage over 5V will result in damage. 2. The U3 PRO won't work well if the current of the power adapter is below 1A. 3. The 3.5mm and 6.35mm headphone jack can output at the same time. Please don't use RCA and AUX input at the same time, otherwise audio mixing will be caused.
