This is probably not the best place to get help with a Peavey Mixer - I would be asking here instead:

I did notice that the Headphones can listen to the main mix - does this include the main faders, and if so is the Headphone level unbalanced or is it just the main outs? Try to narrow down where the fault may be before you go asking there.
