1.Using the latest patch technology, low failure rate
2.Full cable connection design, reliable quality
3.Using 1A 7812 high current regulator tube, connected to the head backlight as stable work
Instructions for use:
1. IN AC/DC 12V-20V Power supply for the drive board. (It is recommended to use a separate power transformer or separate windings to supply it The drive board has a current of 45MA when no backlight is used)
2. L, GND, R: This is the low-level signal input terminal of the driver board. It is used to connect the audio signals of CD players, mobile phones, computer sound cards, preamps, and other audio source devices. When wiring, L, GND, and R correspond to: left channel, ground and right channels.
3. R1 and R2 are two adjustable resistors on the driver board that control the size of the hand swing.
4. Backlight DC12V is used for the backlight of the meter after the driver board is rectified and regulated.
