S/PDIF

S/PDIF is a standard audio file transfer format that transfers digital

audio signals to a device without having to be converted first to an

analog format. This prevents the quality of the audio signal from

degrading whenever it is converted 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.

6-channel Audio

The 6-channel audio output function is supported by using the 4-

channel connector, the audio jacks at the rear panel and configuring

the audio driver. Please refer to chapters 2 and 4
