CA series have the following Advantages.
1:- This amplifier is noise free. it will increase the quality of work.
2:- It can make less distortion for a better quality sound.
3:- Integrate protect impact function of power soft -start, DC output protect function, longtime over-heat protect function and delay function. This function can protect the circuit faster when the amplifier short circuits and overloads. This will give it a steady performance for a long period of time.
