24. Examples 
24.1 12-Channel AD/DA-Converter 
TotalMix' super-flexible routing functions make it easy to turn the UFX into a 12-channel AD/DA 
converter, analog from/to ADAT. 
It’s  easy  to  build  the  setup.  For  a  clean  start  perform  a  Total Reset  from  the  Options  menu. 
Then select the ADAT Output 1/2 in the third row, and pull up the fader of the Analog input 1/2 
in the first row. Then select ADAT 3/4, pull up Analog 3/4 and so on until all 12 analog inputs 
are routed to the corresponding 12 (8+4) ADAT channels. 
Now do the same for the analog outputs: select Analog Output 1/2 and move the fader of ADAT 
Input 1/2 to 0 dB, and so on. An additional monitoring of all or selected I/Os can be easily set up 
for the AES output, or as analog mixdown on one of the phones outputs. 
24.2 4-Channel Mic Preamp 
Use TotalMix to route the four microphone inputs directly to the analog outputs. This turns the 
Fireface UFX II into a 4-channel microphone preamp. The AD- and DA-conversion will cause a 
small delay of the signals of around 0.1 ms (at 192 kHz, see chapter 39.2). But this is nothing to 
worry about, as it is the same delay that would be caused by changing the microphone's posi-
tion by about 3.3 centimeter (1.3 inches). 
24.3 Monitor Mixer 
TotalMix allows ANY configuration of all I/Os of the Fireface. For example, set up the device as 
monitor mixer for 12 analog signals, 16 digital via ADAT and 2 via AES. Additionally, TotalMix 
lets you set up ANY submixes, so all existing outputs can be used for different and independent 
monitorings of the input signals. The perfect headphone monitor mixer! 
24.4 Digital Format Converter 
As  TotalMix  allows  for  any  routing  of  the  input  signals,  the  Fireface  UFX  II  can  be  used  as 
ADAT to AES converter, ADAT to two ADAT splitter and AES to ADAT converter. 
24.5 Analog / Digital Routing Matrix 
The Matrix in TotalMix enables you to route and link all inputs and outputs completely freely. All 
the  above  functionalities  are  even  available  simultaneously,  can  be  mixed  and  combined  in 
many ways. Simply said: the Fireface UFX II is a perfect analog/digital routing matrix! 
24.6 Stand-Alone Recorder/Player 
The UFX II can be used for recording as well as playback of audio signals. As all settings are 
available directly at the unit it is possible to record a live concert completely without a computer. 
Music that  was  copied to  a USB  thumb  drive  before can be played back any  time.  Of  course 
both in combination to any of the other examples above!
