4. Front Audio Connector

The audio interface provides two kinds of audio output choices: the Front Audio, the Rear Audio. Their priority is sequenced from high to low (Front Audio to Rear

Audio). If headphones are plugged into the front panel of the chassis (using the

Front Audio), then the Line-out (Rear Audio) on the rear panel will not work. If you do not want to use the Front Audio, pin 5 and 6, pin 9 and 10 must be SHORT, and then the signal will be sent to the rear audio port.

5. CD_IN Connector

CD_IN is Sony standard CD audio connector, it can be connected to a CD-ROM drive through a CD audio cable.

6. Front Panel Connector

Attach the power LED, IDE LED, reset switch and power switch connectors to the corresponding pins.

9. USB Header

The USB header is available for additional USB port if the USB ports on the rear panel are inadequate. Compared to traditional USB 1.1 with the speed of 12Mbps,

USB 2.0 has a fancy speed up to 480Mbps, which allows faster Internet connection, interactive gaming, and simutaneous running of high-speed peripherals.

10. IrDA Header (optional)

This header supports wireless transmitting and receiving devices. Before using this function, Configure the settings of IR mode from the “Integrated Peripherals” section of the CMOS Setup Utility.

11. 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 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.
