Help with mixer/headphone problems

[LizardTree]

Two days ago I recieved a berhinger ddm4000 to go along with a pair of stanton st-150s. Those first two days everything worked great. Now I wake up this morning and try to spin a mix to find out i can't get any sound out of the left side of my headphones throught channel 1. Throught channel 2 i get sound through both sides of my headphones. All the headphone settings and options for channel 2 work fine but doesn't seem to work properly for channel 1. I tried everything on my mixer and to no avail, i even shifted everything down a channel ( setting my tables to 2 and 3)and it seems that with the farthest left channel it constantly mutes the left side of the headphone, making mixing extremely difficult, at least for a noob. Any thought or suggestions id really appriciate it, starting to think its sort of a hardware problem but I would really love to be proven wrong.

Are all the connections in the back of the mixer correct? Is everything plugged in all the way? you might be experiencing dropout because you don't have both L and R of your RCA plugged in all the way. Also, on the DDM4000 there is a cue split function, is it on? If so, that would explain why you hear only half, as it's designed to listen to cued tracks. Make sure that your headphone levels knob is set to master or main, and try again.

All the connections are set properly and double checked, I havent left the split fuction on but when i turn the split fuction on while using channel 1 it shifts the sound from the right side of the headphones to the left, on channel 2 it takes the sound coming from both sides of the headphones and shifts it too the left side. It almost feels like when i move the headphone jack on top of the mixer into a certain position it wants to get sound out of the left side of my headphones but it doesn't work. Iv tried multiple headphones that are in goodworking order and it has nothing to do with that. Is is possible that the jack behringer gave me to connect my headphones to my mixer faulty?

There is a chance you have a faulty mixer. I would email them and ask for help or a replacement. It sounds like you either messed with the settings within the mixer via the screen, or you just have bad channels + headphone jack.

swap your cartridges to rule that one out, then it's the mixer which I would send back.
