Hi there,
Thanks for posting in the Algoriddim Community.
Please note that djay 2 for Android does not natively support the DDJ-200. You’ll need to be using djay for Android. Furthermore, you’ll need to use the splitter cable provided with the DDJ-200 to connect your audio devices. Find out more here: https://help.algoriddim.com/hc/en-us/articles/360014702992-How-do-I-preview-a-song-through-headphones-pre-cueing-
Let me know if you have any further questions.
Cheers, G
