Brand : FTVOGUE
BulletPoint1 : LED Display LED VU Meter Module RGB Bar VU Meter LED Indicates Melody Light LED VU Meter
BulletPoint2 : The VU meter is a voice‑activated sensor, so there is no need to connect audio, just power on the product, it will flash when there is a sound.
BulletPoint3 : The louder the sound, the more the LED will light up from bottom to top. As the sound fluctuates, the LED will flashing with the music.
BulletPoint4 : Using an independent comparator circuit, although the circuit is slightly more complicated, the structure and principle are easier to understand.
BulletPoint5 : DC voltage between 5V and 12V can be powered, with reverse connection .
BulletPoint6 : STANDARDIZED; Take advantage of three calibrated temperature points with the included NIST standards testing certificate. The calibration ensures all regulatory requirements for the instrument are met

How To Use:
Regardinginput:
The board comes with a microphone, no need to connect an audio , it can sense and receive an external sound source, and control the blinking of the LED lamp beads. The disadvantage is that the sensitivity is not as good as the line input, and it is easily affected by other external sounds.
If you need line input, this step is about the audio(for example, the headphone power amplifier of a mobile phone or computer cannot be connected to the output of the power amplifier or the speaker), you can remove the microphone, and theis introduced directly from the microphone. If the lights are on, adjust the potentiometer counterclockwise to decrease) This connection is recommended.

Note:
Thesensitivity is adjustable, the on‑board adjustable potentiometer can be adjusted for about ten turns, and you can hear a tick inside the potentiometer when you adjust it to the end, counterclockwise to decrease, clockwise to increase.
