I installed the new rack gear this morning. Will wait until Monday to hang wall brackets and mount the PRX cabs. I setup the driverack to send full-range to each amp side and turned on limiter and feedback suppression. For a test, I took a hand-held out front and literally stuck it a foot in front of the cabinet. No feedback. I hung around until they got started and the presenters were loud and clear. I love it when a plan comes together.
