Home Rock Studio Setup & Engineering

I have a home studio that I use primarily for rehearsing Rock music (picture attached). I need assistance with EQ'ing to ensure the best sound quality in this confined space. I use a Presonus SL24R mixer and small Alto Professional powered monitors. Guitars and bass are XLR direct in from Helix pedalboards (no amps). Drums have Evans dBOne low volume heads and the kit is mic'd. Everything works as it is now, but the setup needs a professional touch to get more volume and better sound without feedback. I used to use the SMAART Wizard in my previous Presonus board to get me to that point, but this one does not have it.

Ideal Skills:
- Proficient in sound engineering
- Experienced with home studio setups

Please provide a plan of how you would approach this project, including the type of equipment you would use for the sound testing to achieve optimal setup.
