Configuring Hardware in I/O Setup
For more information, see the following topics:
(Avid HDX, Pro Tools|HD, and HD Native Systems Only)
With Avid HDX, Pro Tools|HD, and HD Native systems, you can define which physical ports on your audio interface are routed to available input and output channels in the I/O Setup. Any changes made here are also reflected in the Hardware Setup, and vice-versa (see Configuring Pro Tools Hardware Settings).

HD MADI, and Pro Tools systems such as the Mbox Pro and the 003 are “hard-wired” and cannot be changed. For third-party and built-in hardware, in the Hardware Setup click the Launch Setup App button to for available configuration options.
To configure I/O routing in I/O Setup:
1 Choose Setup > I/O.
2 Click the Input or Output tab to display the corresponding path type.
3 Click the Input or Output selector for the first interface channel pair, located below the first audio interface icon.
4 From the pop-up menu, select a physical port pair (such as Analog 1–2), to route to a Pro Tools channel pair (such as A 1–2) in the Path Name column on the left.
 
5 Repeat the above step for additional channel pairs.
6 Click OK to save changes and close the I/O Setup.
