The Input page of the I/O Setup lets you create and assign Pro Tools Input channels to receive audio from the physical inputs of your audio hardware.Configure input signal path names, formats, and source channel (analog or digital) on the Input page. Multichannel input paths (stereo or greater) can have any number of sub-paths. Input channels can have overlapping input paths. Input names, channel widths, and physical input mappings are saved with the system and the session, and can be recalled from either.
