the “NI audio 2 dj” has 2 outputs, 1 goes to headphones other splits to monitors(speakers). there is no input. it is USB and connect directly to the PC.
The “numark - mixtrack” is connected to the PC by USB.
Yeah well there’s no record button and if you oppen dj software such as traktor the Record button would be deactivated. However, I thought that audacity might be able to change this.
I’ve had a quick Google, it seems that the inability to record is a crippleware thing …
The main differences between Traktor LE and Traktor Pro are … there’s no facility to record your mixes.
i.e. it is not a hardware limitation, the software which comes with it is partially disabled to encourage you to buy the Pro version software to obtain all the features.
