Features:

1. Smallest volume, PCB size 80*14mm LED module area: 58*14mm

2. Rich in functions, users can ly adjust the actual brightness speed and main peak value of each light bar to match the display effect that suits them

3. The audio input is isolated by TI original signal to minimize the for impact of high-frequency interference of the microcontroller on the series audio circuit

4. Different color lights are set with current limiting resistors to for ensure perfect matching.

Important Note:

1. The microcontroller uses time-sharing sampling during sampling, so that the dual-channel parallel input signal changes very quickly. The amplitude displayed by the two light bars may be different, which is normal.

2. There may be very slight high-frequency noise in extreme cases. It is recommended to replace the signal input line head position with a double-core shielded line.

3. Working voltage: 7-12v current can work above 100MA. It is forbidden to connect the positive and negative in reverse or the voltage exceeds 12V. Will the level light be damaged by human intervention?

Display effect:

1. Bar display + drop after peak  

2. Bar display + disappear after peak  

3. Bar display + (no peak display)

4. Bar display + disappear after peak  

5. Bar display + (three lights)

6. Bar marquee display + peak effect

7. Peak + bar display right jump light two digits drop

Working voltage: 7v-12v 100MA
