LED Light Music Audio Spectrum Dynamic Display

Explain:

●Size: 50 mmx110mm, blue light.

●Diameter of two fixing holes: 3 mm Spacing: 100 mm

●Signal input range: less than 300 mv. 5 v (not too strong signal)

●Power supply voltage: DC 8 v to 12 v

●Current: about 70 mA

Features:

Two buttons S1 and S2, long press (more than 1 second) and short press (less than 1 second and more than 0.2 second). The key function is quite simple.

S1 In the normal display mode, adjust the strength of the input signal. The cycle reduces the number of input signals by clicking, and then automatically returns to the beginning. S1 In the brightness adjustment mode, press incrementse until the level og brightness.

S2 is used to select the display mode in the normal display mode. The same click conversion cycle will automatically return to the next one. S2 is in the brightness adjustment mode, press one level until the brightness. S2 is in the normal display mode, long press will enter the brightness adjustment mode, S2 is in the brightness adjustment mode, long press will save and return to the normal brightness display mode.

Wiring Precautions:

1. Do not use AC power and do not use high voltage.

2. The -/+sign represents the power supply, - represents the negative pole of the input power supply, and+represents the positive pole of the input power supply; The signal strength should not be too high. The signal strength on the headphone jack is generally provided to it. Do not use the power amplifier to output too strong signal, which may worsen the circuit.

3. Audio signal line 3 is the label R L G, which is the right channel signal, the left channel signal, and the label ground (i.e. negative power circuit board)
