Feature●FUNCTION: VU audio driver board adopts professional audio VU driver IC, this IC small pointer contains dynamic compression circuit, logarithmic output characteristics, so as to avoid walking large when the pointer touches the bottom●SPECIFICATION: The warm back light VU meter circuit is powered by DC 9?12V and uses the original IC, which is very easy to use. Each board has been tested and adjusted by our professional test bench, can meet your using requirement●MUTE FUNCTION: The IC has a mute function. The VU panel meter mute function pin will be low level at the moment of power on, which can avoid touching the bottom of the pointer at power on. The pointer will swing a small amount to conform to the power on habit●SWING ADJUSTMENT: In addition to adjusting the load potentiometer, swing adjustment can be used from the input voltage divider circuit. The brightness of the backlight can be achieved by adjusting the resistance value of R9 and R10. With the electrical parameters of the backlight, it can be easily calculated according to Ohms law●DURABLE: The design layout of the VU meter driver board module kit is beautiful and reasonable, without interference and self excitation, adopts PCB material, has long lastingDescription

Note:
1. Before use, make sure the pointer is aligned with the 0 point. If there is deviation, use a screwdriver to adjust the pointer to 0.
2. Backlight design voltage is 9?12v. If the backlight brightness meets the requirements, reducing the backlight operating voltage can greatly extend the life of the backlight. It is recommended to use 9v.
