I would like to switch off the FXs (reverb, etc.) from the mics by just pressing a single button. Between the songs, we talk with the audience and we would like to talk without reverb and sing with reverb. But I need to do that change quickly. How can I do that? Thank you.
You can create a group including the FX. To create a group just double click an empty encoder knob in setup mode. A dialog appears that lets you select the members of your group. Select the effects and name the group "FX". Now you have a group encoder on screen that allows you to mute the effects by pressing the mute button on the group icon. You could also assign a footswitch in the system menue.
