PRE Guide24
For each declared PRE, the I/O Setup Mic Pre-
amps page includes the PRE path name, and 
provides tools to map PRE output channels to an 
audio interface.
Paths can be:
• Renamed, for easier identification after 
changing or renaming audio interfaces. See 
“Naming Paths (Optional)” on page 25.
• Remapped to different input destinations (au-
dio interface analog). See “Remapping Chan-
nels” on page 24.
• De-activated (or re-activated) to manage un-
available or unnecessary I/O resources. See 
“Active and Inactive Paths” on page 25.
PRE paths cannot be deleted. Additionally, their 
I/O Setup configuration cannot be exported or 
imported.
If you have multiple PRE units in I/O setups, the 
order in which the PRE paths appear corre-
sponds to the order in which they were assigned 
in the Mic Preamps tab of the Peripherals dialog.
Channel Mapping
Existing PRE paths must be mapped to specific 
audio interface inputs in the Grid in order for 
audio and remote control to be available in 
Pro Tools.
To map channels:
1 Choose Setup > I/O and click the Mic Preamps 
tab.
2 In the row for the selected path—the high-
lighted PRE name—click in the Grid column un-
der the audio interface and channels to which 
PRE is connected. The first output channel of 
the PRE appears in this column (as the number 
1), while the remaining seven channels fill to 
the right.
3 When you are finished mapping channels, 
click OK.
Remapping Channels
You can move the individual PRE assignments 
to different audio interface input channels.
To remap channels in a path, do one of the 
following:
 Drag the PRE channel to the new location in 
the Grid.
– or –
 Command-click the PRE channel in the Grid 
to open the PRE Output Channel pop-up menu, 
then select an output channel. If you select a 
channel that is already in use, the old and new 
assignments will swap Grid positions.
PRE path in I/O Setup window
To update the Grid with new mapping, 
Command-click a white box in the Grid, 
then select an output channel. If the chan-
nel was already in use, the old assignment is 
removed.
