Audio Connectors
Front Panel Audio Header: FRONT AUDIO
If your computer case has been designed with embedded audio equipment or you are using an audio
bracket (optional). You can attach these components to the FRONT_AUDIO header of the
mainboard. First remove the jumper caps covering the FRONT_AUDIO pins. Use pins 1, 3 to
connect to the case microphone. Use pins 9,5 to connect to the earphone. If you do not intend to use
the FRONT_AUDIO panel, do not remove the jumper caps.
S/PDIF Connector: SPDIF
S/PDIF (Sony/Philips Digital Interface) is an audio transfer file format, which provides high quality
audio using optical fiber and digital signal. This mainboard is capable of delivering audio output
through the SPDIF header. The SPDIF devices that are receiving information from this header must
be SPDIF compliant for optimal effect.
If the jumper caps are in place, jumper cap 1 is on pin 5, pin 6 and
jumper cap 2 is on pin 9, pin 10. If you do not intend to use the
FRONT_AUDIO panel, do not remove the jumper caps.
Attention
：
The front panel audio & the back panel audio can not
use simultaneously.
