Product introduction
This is a worthy driven plate with double needle VU meter LED lighting slab, wiring simple, suitable for 5 to 50 watts of power amplifier and bravery machine amplifier, power amplifier output directly (that is, in parallel on the speakers), backlight wide voltage can use 5 v to 12 v, ac, dc can be driven plate "R1 and R2" adjustable resistor is adjustable pointer bouncing.
Debugging mode
Method 1. Use the signal generator to connect the power amplifier with 1KHz signal, turn the power amplifier volume to the maximum, adjust the adjustable resistance on the driving plate of the watch head, and make the pointer of the watch head indicate the position of "0" on the label.
Method 2. In the absence of a dedicated signal generator, an Android phone can be used as a signal generator to download a signal generator software and output a 1KHz signal to the power amplifier. The adjustment method is the same as above.
