Audio Port Connectors
Line-Out is a connector for speakers
or headphones. The Line-In connec-
tor can be used for an external CD

when 6-channel applications are used,
all three connectors become output
connectors. Line-Out becomes Front
L/R; Line-In becomes Rear L/R; Mic-
In becomes Center/Sub. The 6-CH
mode needs proper setting on O/S and
application. Win98 supports 4-CH only
RJ45 NIC Port

RJ45 port for connection to the Local
