New VU meter driver board, the perfect alternative set TA-7318P driver IC, drive the meter is better, hands quickly oscillates, responsive, and based on the 7318 circuit output signal is further increased, stable performance, beautiful appearance, sophisticated and practical!

And with the expansion of the circuit, increase the peak display function!

Intended use:

1. signal input: driver board provides two kinds of signal input, you can choose one according to your request. (Please note: If you connect the signal source from the back of the potentiometer or the output of the amplifier, the pointer change will be controlled by the volume potentiometer).

① LOW, GND, LOW: It is the low level signal input jack of driver board, you can connect it to CD player / PC sound card / preamplifier audio signal, LOW, GND, LOW Equivalent: left channel, GND, right channel (Setting two potentiometers to control the pointer swing. If it is full signal but the pointer swing does not meet your expectation or the volume swing leads to low or distortion, you can move R2, R3 resistor).

②HIGH, GND, HIGH:

It is the high level signal input terminal of the driver board, you can connect it to the signal through amplifier, the two HIGH terminals correspond to the two RED terminals of the amplifier, GND corresponds to one of the black amplifier terminals.

2. driver board output:

V +, V-, terminal: It is the backlight, support 2 set 12V backlight terminal, when connecting please note the positive or negative electrode.

+, -, terminal: It is the driver board output, connect it to the "+" "-" of the VU counter.

3. power supply

Woking voltage: AC / DC 12-15V (we recommend using the independent power supply)

Rated power: 3W

4.PCB size: 60 * 39mm
