Audio Jacks
The system board is equipped with 3 audio jacks. A jack is a one-
hole connecting interface for inserting a plug.
• Line-out Jack (Lime - CN3)
This jack is used to connect external speakers for audio output
from the system board. Using this jack disables the front audio’s
line-out function.
• Line-in Jack (Light Blue - CN4)
This jack can be connected to the line-out jack of any external
audio devices such as Hi-fi set, CD player, AM/FM radio tuner,
synthesizer, etc. Connect a stereo cable from the line-out jack of
your external device to this line-in jack.
