mixing for the club

Hi,since club systems are mostly mono,if i have some tracks panned to left and right,does that mean that,say if ur standing in the centre of the club,you wouldnt hear the panned parts?

If the system is real mono, you’ll hear everything unless there are some phasing issues between L/R-channels on your music. These phasing issues are why you always should check mono-compatibility of your music.

thanks.
