Headphone volume is low on DDJ SB

I just purchased the new DDJ SB and I am running it with Serato DJ intro. 

The headphone volume on is very low, even when I have my headphones level at max.  It does not matter if I am turned all of the way to the master, or all the way to the cue.  Only if I turn up the channels does the volume increase, but doing this also increases the output volume.  Are there any drivers out there to fix this issue?
