Operation guide：
1. AC/DC12-16V power supply, to distinguish between AC and DC input terminals. L, G, R: This is the two-channel input terminal of the driver board, which can be connected to the audio of the audio source equipment such as mobile phones, computer sound cards, pre-amplifiers (the signal is the signal that can be heard by the earphone), and the power amplifier output terminal to get the signal. When wiring L , G, R correspond to the left, ground, and right channels of the audio source equipment respectively. If the input is a mobile phone, computer sound card, preamp, etc., please turn the DIP switches 1 and 3 to the "ON" end, 1. AC/DC12 -16V power supply, it is necessary to distinguish between AC and DC input terminals.
2. L, G, R: This is the two-channel input terminal of the driver board, which can be connected to the audio of the audio source equipment such as mobile phone, computer sound card, front-end equipment (the signal is the signal that can be heard by the earphone), and the output terminal of the power amplifier to get the signal and wire When L, G, R correspond to the left, ground, and right channels of the audio source device, if the input is a mobile phone, computer sound card, preamp, etc., please turn the DIP switches 1 and 3 to the "ON" end, if the input is To get the signal from the output end of the power amplifier, please turn the DIP switches 2 and 4 to the "ON" end, the signal will be compressed by 11 times. Note: The DIP switch cannot be set to the "ON" end at the same time.
3. The adjustable potentiometer "100R-V" is used to adjust the brightness of the backlight of the vu meter.
4. Adjustable potentiometers "50k-1" and "50k-2" control the beating amplitude of the pointers of VU meter 1 and VU meter 2, respectively.
