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.
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 S/PDIF connector to a S/PDIF audio module bearing
S/PDIF digital output. However, you must have a S/PDIF supported speaker with S/PDIF digital input
to make the most of this function.
6. Front Panel Connector
This motherboard provides six
USB
connectors to link USB
devices, such as mouse, keyboard, modem, printer, etc.
There are two connectors on the PC99 back panel. You can
use proper cable to connect other USB connectors to the back
panel or front panel of chassis.
If the housing has been designed with an audio port on the front panel, you’ll be able to
connect onboard audio to front panel through this connector. By the way, please remove
the jumper caps from the Front Audio Connector before you connect the cable. Do not
remove the yellow jumper caps if your housing doesn’t have an audio port on the front
panel.
