6>.The input voltage can not more than 12V if connect 4ohm speaker.
7>.It is recommended to use a power supply which more than 2A.
8>.Please read use manual and description before use.
7.Frequently Asked Questions:
1.Why is the volume working normally when volume small, and there is turbidity after increase volume?
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.
