L, G, R: These are the dual-channel input terminals of the driver board, which can be connected to the audio of mobile phones, computer sound cards, preamplifiers and other audio source devices (the signal is the signal that the headphones can hear), and the amplifier output terminal to get the signal. When wiring, L, G, and R correspond to the left, ground, and right channels of the audio source device respectively. If the input is a mobile phone, computer sound card, preamplifier and other audio sources, please turn the dip switches 1 and 3 to the ON end. 1. AC/DC12-16V power supply, distinguish between AC and DC input terminals
L, G, R: This is the dual-channel input terminal of the driver board, which can be connected to the audio of mobile phones, computer sound cards, preamplifiers and other audio source devices (the signal is the signal that can be heard by headphones), and the output of the power amplifier. When wiring, L, G, and R correspond to the left, ground, and right channels of the audio source device respectively. If the input is a mobile phone, computer sound card, preamplifier and other audio sources, please turn the dip switches 1 and 3 to the "ON" end. If the input is the output of the power amplifier, please turn the dip switches 2 and 4 to the "ON" end. The signal will be compressed 11 times. Note that the dip switches 1 to 4 cannot be turned to the "ON" end at the same time.

Matters needing attention: Please do not plug and unplug the motor and drive when the power is on, which will easily cause the drive to burn out; also do not adjust the current when the motor is running. The correct way is to first disconnect the power supply, unplug the motor, and then power on again, adjust the potentiometer, and measure the voltage on the potentiometer until the measured voltage is the same as expected. Do not plug in the reverse drive, otherwise it will burn out the drive and even the motherboard
Using Bluetooth 5.0 main control chip, good transmission effect and high stability
With button control, there are control up and down music, volume addition and subtraction, playback, pause, switch machine, etc., and reserved high and low level control interfaces, regardless of daily use, and DIY modification, it is very playable
