Connecting to audio source
AUX three pin wired jack is provided onboard this audio amplifier module to facilitate the connection of the audio module to audio source like mobile, computer, etc.

  1. Mount the board to flat surface via mounting holes.
  2. Connect the Stereo Audio Input connector to the audio source; computer, mobile, CD, etc via provided specfic wired jack.
  3. Power the module via connecting 9-18 volts to the power connector. Please see the polarity of the power supply. The wrong polarity may damage the module board permanently.
  4. Make sure that your source's signal are not cliping.
  5. Adjust the volume of your source for appropriate volume. The volume of the source should be kept below clipping level and should not be more than 1Vpp.
