UR44 mic pre and compressor issue

Greetings.
I have a steinberg UR 44 mic pre and would like to hook it up to my RNC 1773 compressor… Seems like the way I have it hooked up I get constant feedback or the dsignal just doesnt seem to get compressed. Any help would be appreciated.

If someone can give me the correct wiring to and from the devices would be awesome. Thanks
