Move the ratio to 2.0:1.

Add make-up gain.

Use the “Gain” knob under “Loudness” to restore the lost volume.

Apply EQ.

Use the next effect “slot” to load a . This will allow you to adjust the frequencies by adjusting sliders 1-7. This will let you tweak the sound how you like it. Once you do, you can adjust the main “Insert” volume slider until the sounds are balanced how you want.
