UR44 dspMixer without EQ?

Hi everyone.
I want to open EQ on Master Output channel, instead of Reverb. How can I do this?

I’m having Rokit 6 speakers at home. When I’m watching or listening something, they’re giving huge bass even when the volume is low. So I want to cut below 100-150hZ on my Master Output especially at night. Please explain how to do.
