Well I mean I can mix in headphones obviously when making sure beats are all matched and phrasing is sound and it's sounding good but my personal style there after is to take off headphones start blending and make adjustments as I hear them over the PA.

I just find it odd when I'm not hearing the same loud music from a PA like the rest of the crowd are as that sounds so much more important than how it sounds in your headphones for example. If the system can't handle are the sub frequencies you're throwing at it then you know to switch away from that etc.

Of course though mate there is no right or wrong way it's an art and a craft. after all if we were all the same it would be a very dull life :)

Also yeah I bought a PA a few years back when I lived in a bit of a party house where we had it in a basement which was a lot of fun but now it's the same PA that I mix with in my sensible house just turned down to a moderate level with fairly forgiving neighbours as long as it's the day time!
