High Defi nition Audio (HDA)
This motherboard features a 7.1+2 Channel
High Defi nition Audio (HDA) (JC1) codec that
provides 10 DAC channels, simultaneously
supporting 7.1 sound playback and two chan-
nels of independent stereo sound output (mul-
tiple streaming) through the front panel stereo
out for the front L&R, rear L&R, center and
subwoofer speakers. This feature is activated
with an Advanced software included in the CD-
ROM that came with your motherboard. Sound
is then output through the Line In, Line Out
and MIC jacks (See at the picture at right.)
CD and Auxiliary (FP) Audio Headers
A 4-pin CD header is located at CD1, and an
Auxiliary (Front Panel) header is located at
JC2 on the motherboard. These headers allow
you to use the onboard sound for audio CD
playback. Connect an audio cable from your
CD drive to the header that fi ts your cable's
connector. Only one CD header can be used
at any one time. See the tables at right for pin
defi nitions.
