J1, J2, J3 – Audio connectors
3.5mm stereo audio jacks are used for audio connection. The audio codec can operate in
either of the following modes:
•
2.0 mode, which allows for microphone in, line in and line out operation.
•
5.1 mode, which provides six-channel surround sound output. The microphone input
and line in are not available during six channel mode.
Selection of 2.0 or 5.1 mode is made using software.
