The audio input is audio in terminal and GND is compatible with the audio output of general equipment, and the output is also such a pair of lines audio out and GND. It is strongly recommended to connect one of the power outputs of the speaker, the audio of this PCB. The input GND is connected to the GND of the 5v power supply. If it is installed in the device, make sure that the GND of the power supply is the same or completely isolated from the GND of the output audio.
Two white adjustable resistors: signal sensitivity adjustment Red dial switch function: DIP switch 1: is the display of the switch floating point; DIP switch 2: is to switch the split screen dual channel display or full screen mono display; Note: If the AC power supply is converted to DC and independently powered, the GND needs to be the same as the GND of the audio when DC power is supplied.
A green
B blue
1, A shows fluorescence is green，B shows fluorescence is blue (brightness is darker than green) 2, Two board accessories materials, performance, size are the same 3, B is the original production of stocks in Samsung, less stock.
