Active Software Returns
ProFire 2626 allows for a maximum of 26 software
returns The Control Panel software allows you to
reduce the number of software returns in order to
minimize the demands placed on the FireWire bus
and decrease the amount of system resources used
by ProFire 2626 Due to slight differences between
how the Windows and Macintosh platforms handle
audio, this parameter appears differently in the
Control Panel and is described separately below for
each operating system:

Input Channel Order
This section determines the order of the input ports as they appear in your audio software application Groups
of ports can be dragged and arranged in a left-to-right order (the left-most item appears first in the software’s
hardware input list while the right-most item appears at the end)
of ports can be dragged and arranged in a left-to-right order (the left-most item appears first in the software’s
hardware input list while the right-most item appears at the end)
For example, if you would prefer the coaxial S/PDIF ports to appear as the first entries in your audio application’s
list of inputs and outputs, drag the “S/PDIF COAX” icon to the left-most section of the Control Panel

▶ CAUTION: Do not change the input channel ordering while
your audio application is open. This may result in unexpected
performance from your computer hardware and/or audio
software. Once a change is made to this parameter, you may
need to “refresh” or “update” your audio application’s input
routing page to see the updated ordering. Refer to your audio
application’s documentation to learn more about this.

If you have recently changed the sample rate of the
interface and some of the outputs cease to play
back, open the Router tab in the Control Panel and
observe the Output Source Routing section: All
disabled software returns will appear grayed-out and
italicized. Make sure that your audio application’s
outputs are not routed to any of these disabled
