7. Super 5.1 Channel Audio Effect

This motherboard comes with an ALC650 Codec which supports high quality of 5.1 Channel audio
effect, bringing you a brand new audio experience. On the strength of the innovative design of
ALC650, you're able to use standard line-jacks for surround audio output without connecting any
external module. To apply this function, you have to install the audio driver in the Bonus Pack CD as
well as an audio application supporting 5.1 Channel. Picture bellow represents the standard location
of all speakers in 5.1 Channel sound track. Please connect the plug of your front speakers to the
green "Speaker out" port, rear speakers' plug to the blue "Line in" port and both of the center and
subwoofer speakers to the red "MIC in" port.

8. S/PDIF Connector

S/PDIF (Sony/Philips Digital Interface) is a latest audio transfer file format that provides
impressive quality through optical fiber and allows you to enjoy digital audio instead of
analog. Normally there are two S/PDIF outputs as shown, one for RCA connector, the
most common one used for consumer audio products, and the other for optical connector
with a even better audio quality. Through a specific audio cable, you can connect the
SPDIF connector to a S/PDIF audio module bearing S/PDIF digital output. However, you
must have a S/PDIF supported speaker with SPDIF digital input to make the most of this
function.
