DDJ-1000 master volume too low

Last night I played in a club I know the sound very well. Tried the DDJ-1000 for the first time. The first thing I notised is the level of the volume of this controller.
It is very low!
The settings in Rekordbox Output level - headroom is in -3 db.
I had to gain volume on each channel up til the vu meters had 2 red lines. And vu meter in the master volume was all red and sometimes so loud it was clipping. But still the volume was not high enough compared to what I can do with DJM-900 and even my smaller controller DDJ-SR2.

Is there anything I can do to make it better?

I have talked to some other DJ's who have DDJ-1000, and they say that they don't have this problem at all.
Can it be that mine has a problem with the sound?
