Audio Test

Rhino Pi X1 supports LINE OUT and LINE IN interfaces, both of which are 3.5mm audio jacks. They need to be used with microphones and speakers equipped with 3-segment plugs.

Note

The Line-in interface only supports active microphones.

Hardware Connection

  • Connect the microphone to the LINE IN interface of the device (the red 3.5mm jack).
  • Connect the speaker to the LINE OUT interface of the device (the green 3.5mm jack).
