S/PDIF Connector: SPDIF
S/PDIF (Sony/Philips Digital Interface) is a recent audio transfer file format, which
provides high quality audio using optical fiber and digital signals. This mainboard is
capable of delivering audio output through the SPDIF header. One way you would use
this header is by using an SPDIF bracket attached to your computer. This bracket will
have a cable that you can attach to the SPDIF header. This bracket will also have an
RCA connector, similar to that used with most consumer audio products that can output
the data to an S/PDIF device. On the SPDIF header, SPD-OUT is used for output. The
devices that are receiving information from this header must be S/PDIF compliant for
optimal effect. Note that the SPDIF bracket is optional in the packaging that comes with
this mainboard. (See table below for S/PDIF connector pin assignments)
