The left deck only plays out of the left speaker, and the right deck only plays out of the right speaker. I can't get the song to come out of both speakers. please help me!! i checked the videos on how to set up and it looks right to me. i have RCA's plugged into the master output, and the other side (quarter inches) go into my powered speakers.

pleaseee help

Do you hear it in both sides of the headphones?

What mixer do you have?
