What is the maximum number of HD OMNI interfaces that can be used on a Pro Tools|HD system?

• A. Two
• B. Three
• C. One
• D. Four

Answer: (C)

The device I/O topology of a Pro Tools|HD system is designed to use one external interface of the HD family at a time as the primary I/O path. The HD OMNI is a single, self-contained interface that integrates with that system, and the software/hardware architecture supports only one OMNI connected to a Pro Tools|HD rig. This keeps clocking, routing, and DSP resources straightforward. If you need more channels, you’d add other Digidesign/Pro Tools interfaces (like HD I/O or 192 I/O) rather than a second OMNI. So the maximum number of HD OMNI interfaces you can use on a Pro Tools|HD system is one.
