• When you input sound for S/PDIF IN, the LINE_OUT will output the sound.
Mute LINE_OUT to impede sound output from S/PDIF IN.
• The S/PDIF module is purchased separately.
4. ATX power connectors (20-pin ATXPWR)
These connectors connect to an ATX 12V power supply. The plugs from the
power supply are designed to fit these connectors in only one orientation. Find
the proper orientation and push down firmly until the connectors completely fit.

If you will need to replace the power supply in the future, make sure that your
new ATX 12V power supply can provide 8A on the +12V lead and at least 1A on
the +5-volt standby lead (+5VSB). The minimum recommended wattage is
230W, or 300W for a fully configured system. The system may become unstable
and may experience difficulty powering up if the power supply is inadequate.
