16. Configuring the Fireface 
16.1 Settings Dialog 
Configuring the Fireface UC is done via its own settings dialog, the program Fireface USB Set-
tings. The mixer (TotalMix FX) can be configured by starting the program Totalmix. 
The Fireface’s hardware offers a number of helpful, well thought-of practical functions and op-
tions which affect how the card operates - it can be configured to suit many different require-
ments. The following is available in the 'Settings' dialog: 
•  Level of analog I/Os 
•  Configuration of digital I/Os 
• Synchronization behaviour 
•  Current sample rate 
•  State of input and output 
Any changes performed in the 
Settings dialog are applied 
immediately - confirmation (e.g. 
by exiting the dialog) is not 
required. 
However, settings should not be 
changed during playback or 
record if it can be avoided, as this 
can cause unwanted noises. 
Use the drop down menu 
Properties For to select the unit 
to be configured. 
On the right of it the current 
firmware and driver version is 
shown.
