Parton’s 24-karat-gold–plated Shure UR2/KSM-9 wireless mic was created for her appearance on American Idol—to “Dolly [the reality show] up,” as monitor engineer Glass says. It is customized with the electronics, metal finishing and clear-coat done at Glass’ machine shop; the 24-karat-gold plating is courtesy River Gold Plating Co. in Fort Wayne, Ind. Background vocalists use Shure UR2/KSM-9 setups from Professional Wireless Systems, as well as Countryman IsoMax W5 headsets and a pair of hardwired Shure 55SHs.
