Level Indicator Dual 24 Stereo VU Meter AGC Mode LED Music Display Amplifier DIY

Level Indicator Dual 24 Stereo VU Meter AGC Mode LED Music Display Amplifier DIY


Descriptions:
- Ultra-small size stereo level lights, light bar can be adjusted to rise, the rate of decline and peak lamp residence time, the rate of decline. Each lamp set up a separate current limiting resistor, Ensure the same brightness of the different color lights ,Signal input through the op-amp isolation,Avoid single-chip high frequency interference AUDIO
- The minimum volume, PCB the size of 80 * 21mm LED module area : 61* 21mm
- The feature-rich, user can freely adjust each light bar and the main peak of the real speed of light, with the most suitable for their own display
- Audio input through the TI original 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.
- This Level indicator lamps has 15 level brightness control;Ultra-small size stereo level lights, light bar can be adjusted to rise, the rate of decline and peak lamp residence time, the rate of decline. Each lamp set up a separate current limiting resistor, Ensure the same brightness of the different color lights ,Signal input through the op-amp isolation,Avoid single-chip high frequency interference AUDIO

Important note:
1. MCU in the sampling time-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 line head position as dual-core shielded cable.
3. Operating voltage: 7-12v current can work in more than 100MA. Prohibited or voltage exceeds 15v cann't positive and negative reversed, whether the person will cause light damage level

Display effect:
1. strip show+ after peak travel whereabouts
2. strip show after+ the disappearance of the peak travel
3. The strip display + (no peak display)
4. strip show+ right after the peak flow disappears
5. The strip display + (three lights)
6. striped marquee display + peak effect
7. Peak + strip show right jump lamp lights two bits whereabouts

Operating Voltage: 7v-12v 100MA
Colors: 16 Green + 8 red
