The embedded audio modules and codecs can be used as input or output channels for
embedded, digital (AES/EBU) signals.
Depending on the server chassis or configuration, you can find the following audio
connectors on the rear panel:
• Digital audio:
◦ DA-15 connectors: 16 inputs (8 pairs) and 16 outputs (8 pairs) (110 Ohm
balanced).
◦ BNC connectors: 8 inputs and 8 outputs on an XT4K server (75 Ohm unbalanced).
• MADI Digital audio:
◦ BNC connectors: 2 inputs and 2 outputs (75 Ohm unbalanced).
• Audio monitoring :
◦ XLR connectors: 4 analog mono outputs (600 Ohm drive capable).
• Breakout cables with XLR connectors can be adapted on DA-15 connectors.
