Object subject to the picture:
1. Product list: one indicator, welded, with a plug line, with a panel
2. The lamp beads beat with the music melody, the higher the audio signal intensity, that is, the higher the volume, the more the number of LED points will be lit, which can reflect the intensity of the audio signal through the number of LED lights, and the LED beat display screen is also very beautiful:
3. Overall size: length 72mm* width 22mm* thickness 113mm3
4. Indicator supply voltage :DC 9V-12V increase polarity protection reverse connection without burning chip:
5. The sensitivity can be adjusted, such as the indicator full light, reverse clock potentiometer to reduce the signal; If the indicator light is less, the clock potentiometer increases the signal:
The product is a total of four lines, under the premise of separate power supply, the red line is connected to the positive pole of power supply, the black line is connected to the negative pole of power supply, the yellow line is connected to the positive pole of sound source or horn, and the green line is connected to the negative pole of sound source or horn.
Note: THE INDICATOR AND THE EQUIPMENT SHOULD BE POWERED SEPARATELY. If THEY share the same power supply, the NEGATIVE electrode (BLACK wire) of the INDICATOR should not be connected, OTHERWISE THE CHIP will be burned. This case is man-made damage, and we will not be responsible for it.
The small power put within 30W can be directly connected to the horn, more than 30W must be connected to signal input end.
This product can only be used for fixed resistance power amplifier equipment, can not be used for fixed voltage power amplifier, otherwise it can not be done and cause damage!
