The sound is stuck when the volume is turned up, intermittently, and the sound is turned back to normal when turned down. Answer: Reason 1. Because the power of the power supply is too small, the total output power of this power amplifier board is 200W. It is recommended to choose a voltage of 24V and a current of 8A when selecting the power supply. Answer: Reason 2. If there is no problem with the power supply, the power of the speaker may be too low. For example, if you output 50W, but connect a 5W speaker, the volume adjustment will cause a phenomenon of stuttering, and the speaker may be burned out. 2. There is too much noise when playing music, or there is noise when not playing music. Answer: The function of the power amplifier board is to amplify the signal. The main source of noise is the radio clutter in the environment generated by the power amplifier board. So as long as the power amplifier board will have noise. It is recommended that the audio cable should be shielded as much as possible. In addition, there may be noise from the sound source. Normal mobile phones and MP3s will not have such problems. It often happens on some old front-end boards, which are not compatible with the power amplifier board. You can also add audio isolator or coupling capacitance test to see if it can be removed..Find many great new \u0026amp; used options and get the best deals for DC12-24V Digital Amplifier Board 2.1 Channel 2x50W+100W TPA3116D2 Audio Module at the best online prices at Order2india Shopping!
