4X Dual 12 Level Indicator VU Meter Stereo Amplifier Board Adjustable Light Speed Board

4X Dual 12 Level Indicator VU Meter Stereo Amplifier Board Adjustable Light Speed Board Beschrijving

The minimum volume, PCB the size of 80 * 14mm LED module area : 58 * 14mm.
The feature-rich, user can freely adjust each light bar and the main of the real speed of light, with the most suitable for their own display.
Audio input through the TI signal isolation, the maximum to avoid the single-chip high-frequency interference to an audio circuit in series.
Different colors of light alone provided a current limiting resistor.
Guarantee a perfect match.

Important note:
1. MCU in the sampling -sampling, so that there is dual-channel simultaneous parallel input signal changes fast, the amplitude of the two light bar display may vary, this is a normal situation.
2. In extreme cases, there may be very slight high frequency noise. Recommended to replace the signal input position as dual-core shielded cable.
3. Operating voltage: 7-12v current can work in more than 100MA. Prohibited or voltage exceeds 12v positive and negative reversed, whether the person will cause light damage level
Display effect:
1. strip show+ after travel whereabouts
2. strip show after+ the disappearance of the travel
3. The strip display + (no display)
4. strip show+ right after the flow disappears
5. The strip display + (three lights)
6. striped marquee display + effect
7. + strip show right jump lamp lights two bits whereabouts
