Public Address

June 09, 2023

This week on Behind the Bricks, IMS President Doug Boles comes to you from a secure location at the Indianapolis Motor Speedway – the central location of our Public Address sound system! You’ll see the original floor of the room from the 1920s, learn how IMS became one of the largest sound systems in the world and see who’s behind the improved music coming from the Speedway’s speakers!
