Simply push or pull the array into position to create “Straight, ” “C, ” “J” or “Reverse J” coverage patterns. And once set, the system automatically changes the EQ to maintain optimum tonal balance for each coverage pattern. So whether you’re playing at floor level, on a stage, or facing raked seats or bleachers, you can now adapt your PA to match the room.Flex array is a flexible baffle that can be configured into four unique shapes (“Straight, ” “C, ” “J” or “Reverse J”), allowing the customer to choose the best possible coverage pattern for the application Vertically oriented 8-driver mid/high line array, with each driver mounted on a custom 100° waveguide, helps deliver wide, consistent coverage 12-inch LF driver provides high performance at low frequency for strong low-frequency output Bi-amplified design with 2 high-output, Class-D amplifiers to separately power the FLEX array and 12-inch LF driver 2 input channels with independent volume controls and Line Level/Mic switch on Channel 1Flex Array Shapes Straight Pattern Use the straight pattern when the audience is standing and their heads are approximately at the same height as the loudspeaker.
