Located north of Los Angeles, this 260 acre theme park is best known for its thrill rides. With the opening of the Great American Revolution in 1976, Magic Mountain became the first park in the world to have a modern, 360 degree steel looping coaster (though previous roller coasters with loops had been built and dismantled elsewhere due to safety issues). When it was built, there was very little in the way of surrounding brush. Now, the tracks are surrounded by trees and bushes, which prevent the riders from knowing the track layout beforehand. Six Flags Magic Mountain will become the Roller Coaster Capital of the World with 18 roller coasters in 2011.

MLA provided the audio control equipment for the Batman roller coaster. Designed for the theme park industry, these computer interfaces provide the ability to route and control the show audio. Each channel can be muted for emergency or routine paging and can handle multiple channels of music or prerecorded announcements.
