5-2-1 Conguring 2/4/5.1/7.1-Channel Audio
The motherboard provides six audio jacks on the back
panel which support 2/4/5.1/7.1-channel
(Note)
audio.
The picture to the right shows the default audio jack
assignments.
The integrated HD (High Definition) audio provides
jack retasking capability that allows the user to change
the function for each jack through the audio driver.
For example, in a 4-channel audio conguration, if a Side speaker is plugged into the default Center/Sub-
woofer speaker out jack, you can retask the Center/Subwoofer speaker out jack to be Side speaker out.
5-2 Conguring Audio Input and Output
High Denition Audio (HD Audio)
HD Audio includes multiple high quality digital-to-analog converters (DACs) that support 44.1KHz/48KHz/
96KHz/192KHz sampling rate. HD Audio features multistreaming capabilities that allow multiple audio
streams (in and out) to be simultaneously processed. For example, users can listen to MP3 music, have an
Internet chat, make a telephone call over the Internet, and etc. all at the same time.
