Line IN/OUT

Audio Testing

Note

1. The Line-in interface only supports active microphones.

2. Audio devices cannot be used by Android and Ubuntu systems simultaneously. When switching between systems, you need to switch the audio device.

Hardware Connection

• Connect the microphone to the LINE IN port (red 3.5mm jack)
• Connect the speaker to the LINE OUT port (green 3.5mm jack)
