A.No. The UA-1EX does not output a digital signal in realtime when an analog signal is input to the INPUT (Line In) and/or MIC jacks.
For your reference, you should set the REC SOURCE (recording source) switch to ANALOG when you input analog signals to the UA-1EX's INPUT and/or MIC jacks.
The following block diagram shows the UA-1EX's signal flow when the recording source is set to ANALOG.
