JBL AC26 AE Series Array Guide - Page 10

Depending on the height of the bleacher sections and associated vertical coverage requirements the horn may be left in its standard orientation with the enclosure rotated as mentioned above. With a 60o x 40o model this would allow the 60o pattern to cover the bottom to uppermost row when used with a short to medium height bleacher section. A 60o x 60o horn pattern can also be considered to reduce the required number of enclosures. With taller or split level bleacher seating areas Arrays 13 & 14 will address the seating geometry better, using separate enclosures and amplifier channels to address lower and upper enclosure amplitude shading and E.Q. requirements. Figure 7: Distributed and rotated AM5212/64 or AM5212/66 enclosures oriented for optimal coverage with minimal wall interaction. Summary These examples are only some of the uses of the array types that follow. They can be modified or augmented to meet the particular needs of your project. We hope you will find them useful in providing a starting point for your next project. 10
