The playback from a storage device does not change the current sample rate. To match pitch 
and speed, the sample rate has to  be  set manually to the correct value. Playback can be as-
signed to multiple outputs. 
The UFX can play back externally recorded WAV files, as long as these have 16 or 24 bit reso-
lution. 
The recording signal is taken before EQ and Dynamics, on both inputs and outputs. To record 
with EQ/Dyn, activate REC on an output and route a signal processed by the input EQ/Dyn to 
that output. The insert point of playback is at the same place. 
The block diagram shows the signal flow for various situations, depending on the state of Loop-
back, EQ for Record and Play active. In the diagram Loopback and EQ are switched to off, but 
a playback is active in the input. 
Some extra notes that are worth to be pointed out again: 
•  The  signal  recorded  by  audio  software  is  usually  that  from  the  input.  But  when  the  option 
DSP – EQ for Record  has  been  activated  in  the  Settings  dialog  the  software  receives  the 
Play input signal – as soon as a playback is started from the USB device. 
•  On an output Echo/Reverb gets recorded. To add Echo/Reverb to a playback the playback 
must be assigned to an input. 
•  A playback via USB can not be processed and immediately recorded again via DURec. Whi-
le the block diagram seems to present such functionality please remember that DURec can 
do only one thing at a time – record or playback.
