Characteristic:
1. Dual 12-bit music screen spectral level ultra-small volume stereo level lamp can freely adjust the rising and falling speed of the light bar and the dwell time and falling speed of the peak light. Each lamp is separately set with a current-limiting resistor, which not only ensures that the brightness of different color lamps is consistent, but also ensures that there is no light or dark change when the lamp is much brighter. The signal input is isolated by the operational amplifier to avoid the high-frequency interference of the single chip computer from being connected into the audio.
2. Classic color matching: 7 green+2 orange+3 red
3。 When the single-chip microcomputer uses time-sharing sampling, there may be differences in the amplitude displayed by the two light bars when two channels input the same signal in parallel
4. In very extreme cases, there may be very slight high-frequency noise. Please pay attention to separate power supply and try to replace the input line of the lamp board with the shielded line.
