I am upgrading my PA and came across the XTI series and the software downloads but they are not well explained to a novice like me. Does the HiQNet take the place of something like a DBX Drive Rack? I assume you can set crossover points. I read it will optimize for JBL speakers ( I own JBL Mains but not subs). I am in a cover band and do not plan on bringing a laptop to every gig. Is this something you set once and leave unless you change components? Thanks for any help.
