The C4o is a four-channel analog output card for the AllFrame Multi-Modular I/O System. Each channel can be individually set to one of five output levels (+28dBu, +24dBu, +18dBu, +4dBu, or Mic) to maximize each output's flexibility when connecting to other components in the audio system.
The card's output levels can be set from the Pro64 Network Manager software using a simple drop-down menu. Simply select a level setting for an output on the card and it stays that way until you need the output level to be different for another application.
