what is needed if I wanted to connected a third party media player to channels 3 & 4 of my controller? For example a Traktor D2 or Pioneer XDJ-1000 or a turntable with DVS.
Just a set of phono cables. As long as the device outputs a line level signal you just flick the switch over and that’s it.
Timecode is slightly different but it’s covered in the user manual.
