The louder the sound, the more the LEDs are lit from bottom to top. As the sound fluctuates, the LEDs will jump with the music,
especially when playing DJs.
Poduct description:
With anti-reverse protection diode, it can effectively prevent the circuit from being burned due to reverse connection of the power polarity, which is more suitable for DIY.
About signal input: The board has its own microphone, which can sense the external sound source to control the flashing of the LED lamp bead.
The disadvantage is that the sensitivity is not as good as the line input, and it is easily affected by other external sounds.
If you need line input, this step is about the audio signal (such as the phone or computer's headphone jack is, can not be connected to the output of the amplifier or the speaker, the signal is too strong, if it is really connected, you need to attenuate the signal), you can Remove the microphone and the signal is directly introduced from the microphone. If the light is fully illuminated, adjust the potentiometer (reverse clock reduction).
Sensitivity adjustment, reverse reduction and increase, can be screwed about ten times, screwed to the end, you can hear the internal ticking.
The induction microphone, also called the microphone head, relies on it to receive the sound. It can also remove the microphone and introduce the sound source signal from the microphone pad. Note that it cannot be connected to the amplifier or the speaker. The signal is too strong and needs to be attenuated.
