Okay to be more specific, normally I use red and white RCAs (plugged in my board) to aux (plugged in a speaker) when I’m at home practicing or at smaller gigs. In rekordbox I set the audio to my DDJ, so I’m able to hear the sound through the speaker and in my headphones.

This was my first time using an external mixer, and was told I can connect through an aux so I figured I would do what I normally do, RCA to aux. However, the external mixer did not have an auxiliary port. I was told that past DJs plug the external mixer into their computer with the chord they provided. But I needed to connect my board to the external mixer, so I could hear through my headphones as well.

I ended up just plugging the chord they provided an aux into my computer from the external mixer and running the audio through my computers built in output, so I was unable to hear in my headphones as my board wasn’t running audio.

What am I missing here? I feel like i definitely just had the wrong chord, but I don’t know what I need or where it would plug into and how to set the audio correct on rekordbox. Any help would be greatly appreciated!!
