Convenient decode board input port: the board is provided with a MP3 decoder board audio input hub (specifications 3P-2.0mm) and to decode board power supply of 12V DC regulated power supply output hub 2P-2.0mm. Use the board output 12V power supply to supply the decoding board, the actual wiring when decoding in audio input to GND don\\&39;t pick capable of reducing interference; if the decoding board separate power supply must be connected to GND. This shop has a variety of 12V power supply of lossless audio WAV+MP3 decoding board and decoding board with the amplifier board power supply end of the positive and negative poles corresponding, the wiring is very convenient, the hand can directly plug can sound
