Q: Sound distortion.Please change the adapter power supply with higher voltage level. 2>.Why is the volume working normally when volume small, and there is pause after increase volume? Q: The input power is insufficient.Please change the adapter power supply with higher voltage level. Power supply itself intermittent power-off protection.Please change a match power adapter. The power of the power supply is too large so please reduce the power of the input power. The power amplifier board is seriously heated resulting in trigger overheat protection.So please increase the radiator. 8.Package: 1>.1pc XY-AP15H 15W*2 Bluetooth Amplifier Module 2>.1pc 6mm knob cap 3>.1pc DC-005 power adapter 4>.2pcs shell 5>.4pcs M2*11mm Copper column 6>.4pcs M2*3+5mm Copper column 7>.8pcs M2*5mm screw
