Eurorack UB1202FX Behringer

New

Been banging my head on my desk TRYING to get this to work.
I gave up :-(
I am now reaching out to you . . .


Here is what I am trying to do.


Play music on the internet Using my mixer


Control volume of music
Control volume of XLR Microphone
Kinda like a radio station, 


we hear the DJ talking....he plays music....he talks as the music is playing


The Music is coming from my PC
I do not want to hold a microphone near a speaker, that would sound horrible. 


Gosh is hard for me to express what I am trying to do,  but hope you understand.
