ProFire 2626
Output Source Routing
This section lets you select the audio source for 
each hardware output pair on the interface   
The Router has four columns of drop down menus:  
These columns (from left to right) represent the 
Analog Outputs, the first set of ADAT Outputs, the 
second set of ADAT outputs, and finally the the 
coaxial S/PDIF output   
To use the Router, first locate the pair of hardware 
outputs to which you’d like to send audio   Next, 
click the downward arrow to open the drop-down 
menu and select the audio source you’d like to 
connect to your chosen output   ProFire 2626 will 
now route that audio source to your selected output 
In the drop-down menu, the analog, ADAT, and  
S/PDIF inputs correspond to the analog, ADAT and 
S/PDIF hardware inputs found on the interface   The 
“SW Return” selections correspond to the outputs 
of your audio software, while the “Aux Send” selections correspond to the stereo Auxiliary Send outputs of the 
DSP Mixer described in the previous section   “Mixer Out” is the master output of the ProFire 2626 DSP Mixer 
Note that if any of the drop-down selections appear grayed-out and italicized, this means that the stream is inactive 
(see the “Why are hardware inputs and outputs disabled?” box on this page for additional information)   Select 
a stream that is not italicized or grayed-out from the drop down menu to route an active stream to your chosen 
output 
Active Input Ports
These checkboxes determine which groups of hardware inputs are currently active on the interface   If a box is 
checked, its corresponding inputs are active; if a box is left unchecked, the corresponding ports are not active and 
the audio software will not receive any signal from this input until it is made active again   Be sure to deactivate 
any ports that are not being used as this will reduce the demands placed on the FireWire bus and decrease 
the amount of system resources used by ProFire 2626   Deactivated inputs and outputs will be grayed-out and 
italicized in the Control Panel 
Note that at least one group of inputs must be active;  the Control 
Panel will not allow you to disable any more than three of the four 
available check boxes  
Windows users:  Note that inputs and outputs will always appear 
in your audio software, regardless of how these checkboxes are 
set   However, signals associated with deactivated ports will not be 
received by the software 
Why are hardware inputs and 
 outputs disabled?
When the interface operates at higher sample 
rates (i.e., 88.2/96 kHz or 176.4/192 kHz), certain 
hardware input and output ports become disabled 
due to the design of the S/MUX II and S/MUX IV 
protocols.  When this happens, the Control Panel 
automatically scales back the number of software 
return channels to match the number of hardware 
outputs.
Additionally, you can choose to disable unused 
hardware input ports and/or software return channels 
to minimize the amount of system resources used by 
ProFire 2626.  Both of these occurrences may result 
in Router output sources appearing grayed-out and 
italicized.
NOTE:  Audio signals received 
at disabled input ports are not 
transmitted to the computer through 
the FireWire cable.  However, signals 
present at the hardware inputs are 
always audible through the DSP 
Mixer/Router even if its corresponding 
ports have been disabled in the 
Router.  Furthermore, the interface can 
still receive digital clocking information 
through the S/PDIF or ADAT ports 
even if they have been disabled from 
this menu.
