Note:
Note:
All settings denoted by an asterisk (*) are the Default Factory Settings.
If a S/PDIF source is connected to the board, the AES3/EBU jumpers (J21 and J29) should be unpop-
ulated to ensure proper operation. If an AES3/EBU source is connected to the board, the S/PDIF
jumpers (J4, J9, J14, and J18) should be unpopulated to ensure proper operation.
