The Digital X Bus's open architecture means you can configure the console's I/O exactly as you see fit, without having to pay for I/O formats you'll never use. The console ships with two I/O Option cards out of the box—the Sync Card, which provides Word Clock and LTC I/O, and the Mix Out Card, which provides control room and phones outputs, as well as analog and digital outputs for the main mix bus. Here's a rundown on the currently available cards:
