1. Sufficient power supply is recommended. The current must be large enough, otherwise the power of amplifier and horn can not be used, otherwise it is easy to play the jam.
2. Please control the appropriate volume of the small power horn, with the appropriate horn and box, the sound effect will be better.
3. There is a fever phenomenon in the use of digital power amplifier, and the heat dissipation can be strengthened.
4. The use of 4. chip super power will cause sound stuck, which is the protection function of the circuit. It belongs to normal. It only needs to reduce the volume appropriately, if the power is not enough, the stuck phenomenon will also occur.
