Douk Audio Micro Dual 12 LED Level Indicator VU Meter Music Display Analyzer DIY
Item description
Description:
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.
Advantages:
• Custom 12 segments three colors LED light bar (7 green + 2 orange +
3 red).
• The rising speed and the falling speed of the light bar, the holding
time and the falling speed of the peak can be adjusted separately.
• Real-time mode and AGC mode selection (super wide range of AGC
adaptive algorithm to ensure the best effect)
• Small size, can be easily loaded into small case.
• Single button operation.
• Increased brightness adjustment function
Operating Voltage: 7V-12V / 100MA
Colors: 7 Green + 2 orange + 3 red
This level lamp Have standard display mode and Wide range of automatic gain control(AGC)Mode
Package include:
- 1x Mini Dual 12 Level indicator
- 1x 5Pin Cable
Features:
1. The minimum volume, PCB the size of 80 * 14mm LED module area : 58 * 14mm
2.
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
3. Audio input through the TI original 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. Guarantee 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 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 12v positive and negative
reversed, whether the person will cause light damage level
We have the Function operation video and file ,if you want it pls send us message :)
