Traktor Kontrol S3. Changing the EXT (external) from Mic to Line in.

It&taken me a number of weeks to learn how to change the external input on the Traktor Kontrol S3 from microphone to line in. It&frustrated me for hours so I decided to do a quick tutorial. This is really important step when you want to do live streaming. In my setup I use the booth output which is quarter inch Jack to RCA (phono) and send the line back into the controller on Channel D. In this tutorial I show you how to change it. Hint: Hold Shift and Press EXT!
