Master Out DDj Ergo

Hello

I am using a DDj ergo to present a radio show and was wondering if both master outs will work simultaneously?

We need to use master 2 to connect to the broadcast equipment but the studio we are in is ageing and the music we play is slowly destroying the kit.. I want to buy a set of powered monitors to take the strain away from the old radio kit but just wondered if it would work before I spend?? 

So I Would have broadcast gear in master 2 with phono connectors and powered monitors in master 1. Will they both give output

??
