Question

What does the Floor Monitor contour do?

Answer 1

Because the gain structure of the StudioLive AI loudspeakers was designed to optimize the dynamic range of an entire PA system. 

Most other powered speakers in this price class aren't. Professional mixers output from 22 to 26 dBu—for example, StudioLive 
mixers output +24 dBu—and for optimal performance, the speakers should match that level.
