I am in a situation where all my cables are packed into a road case.  I 
have all that is balanced using balanced cables but there still is some 
hum.  I think some of it is off my new mixer (alesis studio 12R) before 
this mixer i was using a mackie 1604vlz.  I think it had a lower noise 
floor.  Almost all my cables where made by me and are shielded and of good 
quality but what can i do about the power cables?

>>>Having everything all in one case can definitely lead to some hum, but 
there's still things you can do to avoid it.  Obviously you're using TRS 
cables where applicable, so that's a good start.  The biggest thing you 
can do, is keep your audio leads as short as possible, and definitely run 
all of them on onhe side of your rack, while keep all the power cords on 
the other.  Having audio lines laying next to power cords is a big no no.

As for your mixer, why oh why did you go from a Mackie to that Alesis?  I 
can guarantee you that the Alesis will have a higher noise floor than the 
Mackie, which are known to be some of the best mixers for the price.  In 
fact short of a Neve or SSL (c'mon lottery!), I won't buy anything other 
than Mackie. <<<

Any advice other than the power conditioner. I am totaly packed for room 
in this box so I would have to mount it 
in the back some how.  so other than that what can I do?

>>>Well, the easiest thing to do (albeit more $$$) would be to get a 
bigger rack.  If not, you can buy just the rack rails and mount them in 
the back of the case if you have room.  Most of the rack mounted power 
strips aren't very deep, so this should work.<<<
