Main Mix to auxes

Can anyone give me the steps to run the stereo main mix through auxes as well as through main outs to drive 2 different sets of speakers. The aux mix should still reflect the master fader level.
I need to have separate sends as the 2nd set are a different make and require different eq.

That’s why God invented matrixes…
feed the L/R into two seperate matrixes one for each set of speakers you want seperate processing on.
