The I/O Setup provides tools to label, format, and assign Pro Tools input, output, insert, and bus
audio signal paths both for individual sessions as well as for your specific Pro Tools system.
I/O Setup also provides controls for PRE (Mic Preamp) signal paths, and Delay Compensation settings for hardware inserts.
The I/O Setup displays a graphical representation (
cross-point matrix) of the signal routing for physical input and output paths for each connected audio interface. Like a virtual patchbay, I/O Setup controls let you route physical inputs and outputs on the audio interface to Pro Tools input and output channels. For Avid HDX, Pro Tools|HD, and HD Native systems, some of these controls mirror the routing controls found in the Hardware Setup —changes made to physical routing in one is always reflected in the other.
The I/O Setup also includes controls for creating internal mix busses and for creating and mapping output busses.
