Get ready to pour that beer for me... lol
Open your DJM-450 Setting Utility app and configure the 1/2 output for REC OUT:
Now within Mixlr, click Select Source at the bottom of the Any Input option, and select DJM-450 > Channels 1 & 2.
Sorry I don't have my 450 connected to give you a screenshot of that (only visible when connected), but it's pretty straight-forward.
Let me know if you have any other questions.
