Overview The vu audio display level meter module can receive analog audio and program signals transmitted by the line, and generate the required audio power and then turn to bar display. The module has a wide impedance matching band, which can be widely used in audio system audio source equipment output, mixer output, line-transmitted program signal output, audio amplifier, karaoke device, and power amplifier output volume level display. The power consumption of the module is low, and the light beam can be displayed in red, green, yellow, etc., or can be displayed in more than two colors to indicate each incremental area and enrich the visual effect of the program. 1. The product is a two-channel stereo display; 2. There is a peak hold display above the 5th segment of the light beam, which can be turned on or off by an external switch; 3. The module has adjustment parts, and the sensitivity and balance of the two channels are adjusted through the potentiometers W1 and W2 on the board; 4. The input can be selected in one of two forms: A or B. Connect the module to the output of the audio device and send the LED light bar display after the root mean square detection; 5.
