Well, after many hours I have figured out the problem.
If you buy the Digital2Go controller, that is bundled with Virtual DJ LE Lite, it is NOT capable of doing what they claim it is capable of doing with a “stereo splitter.” The ONLY way you can have/use a headphone cue (ie, one channel the audience is hearing, the other channel is through the headphones, only) is IF YOU UPGRADE! Which costs a decent amount of money.
This is all from Numark. They claim that the Dj2Go is simply for a “consumer.” Therefore, “consumers have no need for a headphone cue.” – Quote from Numark
If anyone has any other suggestions on affordable software, for a consumer(myself) that DOES have a headphone cue, PLEASE let me know.
Thanks!
