High Performance LED Audio Level Indicator VU Meter with Multiple Display Modes
DESCRIPTION

Features:

1. Smallest volume, PCB size 80*14mm LED module area: 58*14mm

2. With multiple functions, users can freely adjust the actual speed of each light bar and the main light.

3. The audio input uses TI signal isolation to minimize the high-frequency interference caused by MCU series connection to the audio circuit.

4. Different color lights provide current limiting resistors.

Important tips:

1. During the sampling time, the microcontroller makes the dual-channel parallel input signal change rapidly, and the amplitude displayed by the two light bars may be different, which is normal.

2. In extreme cases, there may be very slight high-frequency noise. It is recommended to replace the signal input line with a two-core shielded line.

3. Working voltage: 7-12V current above 100MA can work. Disabling voltage above 12V or reverse connection of positive and negative poles will cause a certain degree of optical damage


Visual effects:

1. Display area + position after tripping peak

2. Bar display + after peak disappears

3. Bar display + (no peak display)

4. Right key display + after maximum value disappears

5. Bar display + (three lights)

6. Bar subtitle display + spike effect

7. Two lights on the right side of the bar display


Working voltage: 7V-12V 100MA

The level light has standard display mode and multiple automatic gain control (AGC) modes
