It is a dual 12-bit music level indicator.Each lamp has a separate current limiting resistor,which not only ensures the brightness of different colors of lamps is consistent,but also ensures that there is no change in the brightness of the lights when the lights are much brighter.The signal input is isolated by the op amp to avoid high-frequency interference of the microcontroller from entering the audio.
1>.It is displayed in three colors
2>.Dual display music spectrum
3>.It is ultra small and uses stereo channels.
4>.It can freely adjust the rising and falling speed of the light bar and the dwell time and falling speed of the peak light.
1>.Product Name:Dual 12-bit Music Level Indicator
2>.Input Voltage:DC 7V~12V
3>.Power Current:100mA (Min)
4>.Audio Output:Connect to the front-end audio signal,disable power output
5>.Light Color:green,orange and red
4.Instructions for Use:
1>.Botton switch:Short press the button to switch to time-limited mode.Long press for more than two seconds to enter the brightness adjustment mode,and long press for more than two seconds to enter the speed adjustment mode.
1.1>.Mode 1:Normal display without peaks.
1.2>.Mode 2:There are peaks,vertices stay,and fall back.
1.3>.Mode 3:There is a peak,the apex stays,rises to the highest point,and disappears.
1.4>.Mode 4:Two lights are displayed.
1.5>.Mode 5:Display a light.
1.1>.Mode 1:Brightness adjustment mode,there are 3 levels of brightness adjustment,short press to set.
1.2>.Mode 2:Speed adjustment mode,there are 6 levels of mode adjustment,short press to enter adjustment.
1.3>.It is not recommended to change the default value.
4>.There are eight function display modules.Long press the button to switch the display mode.There is no power saving capability.
5>.After the setting is completed,re-analyze the power on or the previously configured mode.Long press the key for 4 seconds,the light bar will light up every second,and each time the invitation light is on,it will enter the next mode.
1>.The microcontroller uses time-sampling.When two channels are connected in parallel to input the same signal,the amplitude displayed by the two light bars may differ.
2>.In very extreme cases,there may be very slight high-frequency noise.Pay attention to power supply separately,and try to replace the input line of the lamp board with a shielded line.
3>.The audio signal of the music light needs to be greater than 60% of the music volume for normal use.
4>.Because the acquisition signal line is more sensitive,when the two audios are floating,the LED display will jump,which is normal.
5>.Do not use it with overvoltage,and do not connect it to the power line.
1>.1pcs Dual 12-bit Music Level Indicator
2>.2pcs 20cm 5P wire
