Sound distortion from headphones when the cue is on for DDJ-400

Hello everyone,

Just finished setting up my ddj-400 and eveything seems to be working fine except for the fact that my ears bleed when listening to a cued track through my headphones. I’ve played around with the audio settings through preferences in Rekordbox but the distortion is only the same or worst….

My setup is as follows: DDJ-400 connected to my MacBook Pro DDJ-400 connected to some Pioneer monitors with RCA cable Headphones connected directly to the DDJ-400

Can’t seem to fix this issue, any help appreciated

Edit: I should mention that the headphones I’m using are Shure SRH440 and tried using a different pair of headphones but the problem remains
