S/PDIF
S/PDIF is a standard audio file transfer format that transfers digital
audio signals to a device without having to be conver ted first to an
analog format. This prevents the quality of the audio signal from
degrading whenever it is conver ted to analog. S/PDIF is usually
found on digital audio equipment such as a DAT machine or audio
processing device. The S/PDIF connector on the system board sends
surround sound and 3D audio signal outputs to amplifiers and
speakers and to digital recording devices like CD recorders.

The 4-channel audio connector which supports four audio output
signals: center channel, subwoofer, rear right channel and rear left
