Help in analog summing

[Speaker13]

Hello, I am using cubase 8.5 I am analog summing out my mytek converters into my summing device. Prob is that I am monitoring through cubase input. I would like to ad effects in the chain of the input. Like a bus compressor or EQ. Anyway when I want to solo a instrument I am mixing it automatic mutes the input channel and I cannot eq a instrument in solo. How can I disable it so the input works on it's own. So when I mix and solo a instrument it does the bother the input. Thank you
