Each year, hundreds of thousands of people flood Main Street in Sturgis, SD, and ride the roads that connect the many towns of the Black Hills region. The event's PA system features 16 Technomad weatherproof loudspeakers over a four-block area for outdoor public address and entertainment. The loudspeakers are otherwise being used this summer to simulcast programming from local radio station KNKL-AM (The Knuckle), and will remain in place for future downtown events.
