1X(Dual 12 Music Level Indicator LED Spectrum VU Meter Amplifier Lamps4759
1X(1. 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.
2. Audio input through the TI signal isolation, the maximum to avoid the single-chip high-frequency interference to an audio circuit in series.
3. Different colors of light alone provided a current limiting resistor. a perfect match.
Style:Finished kit
Colour: Black+white
Material:PCB
Package Contents:
1 * Double 12 bit LED level display board
1 * cable
Notice:
1. MCU used time-sharing sampling when sampling, so that there is dual-channel simultaneous parallel input signal changes fast, the amplitude of the two light bar display may may be differences, this is a normal situation.
2. In extreme cases, there maybe have very slight high frequency noise. Recommended to replace the signal input wire to dual-core shielded wire in head position.
3. Operating Voltage: 7-12V, Current can work in more than 100MA. Prohibited Voltage exceeds 12V or positive and negative reversed, otherwise it will cause level indicator damage.
Only the above package content, other products are not included.
Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.)
