Video Output Setup
You can assign a video source or bus to an output and each output is assigned to an XPression framebuffer.
Switcher outputs are assigned to XPression Virtual Outputs from DashBoard. You must set up the Virtual Output on XPression before it is available to the switcher. The Virtual Outputs can be added from the Inputs/Outputs tab on the Hardware Setup window (Edit > Hardware Setup). Refer to the documentation that came with your XPression system for information on setting up Virtual Outputs.
