12. 5.1 Channel Audio Effects
The motherboard is equipped with the CODEC ALC655 chip, which provides
support for 6-channel audio output, including 2 front, 2 rear, 1 center and 1
subwoofer channel. ALC655 allows the board to attach 2, 4 or 6 speakers for
a better surround sound effect. To apply this function, you have to install the
audio driver in utility CD as well as an audio application supporting 5.1 Channel.
The illustration shown below represents the standard location of all speakers in
5.1 Channel sound track. Connect the front speaker to the green audio output;
connect the surround sound speaker to the blue audio input and connect the
center speaker/subwoofer to the red microphone input.
