★FAQ★
1, volume up the sound lag, intermittent, the volume can be played normally after turning down.
A: One of the reasons: caused by the power supply power is too small, the total output power of this amplifier board has 60w, power supply selection recommended voltage in DC12V, current in about 5A.
Reason No. 2: If the power supply is not a problem, it is possible that the power of the speaker is too small, such as the output of 20W, but connected to a 3W speaker, the volume is turned up, there will be lagging phenomenon, there may be burned speakers.
2, too much noise when playing music, or do not play music also has the bottom noise.
A: The role of the amplifier board signal amplification, the main source of noise is the environment of radio clutter generated by the amplifier board amplification, so as long as the amplifier board will have noise. It is recommended that the audio cable with shielding function as much as possible. Then there may be audio source noise, normal cell phones and MP3 will not have, mostly in some old preamp board, and our company's amplifier board is not compatible, you can increase the audio isolator or coupling capacitor test to see if it can be removed.
