Almost every venue and person using multiple wireless microphones in the United States will need to reconfigure their systems before July 13, 2020, or sooner in most areas, to comply with new federal regulations and avoid interference. Since the definition of wireless microphones includes in-ear monitors, intercom systems, and interruptible fold back ("IFB") systems, more devices will be impacted by the new federal regulations than most people realize. FCC decisions concerning the incentive auction and the subsequent repacking of the TV band will significantly impact wireless microphones.
