Mini Dual 12 Level Indicator LED Light Bar VU Meter Stereo Amplifier Board Adjustable Speed with AGC(A)

Mini Dual 12 Level Indicator LED Light Bar VU Meter Stereo Amplifier Board Adjustable Speed with AGC(A) Description

1. The minimum volume, PCB the size of 80 x 14mm LED module area : 58 x 14mm 2. 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 3. Audio input through the TI signal isolation, the maximum to avoid the single-chip high-frequency interference to an audio circuit in series 4. different colors of light alone provided a current limiting resistor. a perfect match. 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 , 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 12v positive and negative reversed, whether the person cause light damage level Colour:As shown Material:plastic type: A Package Contents: 1x Mini Dual 12 Stereo Level indicator lamps board Diy Kits(DIY Kit Black Board) 1x 5Pin Cables 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.
