Arraying
The concept of arraying the TFS-780 Flashlight system is to create part of the surface of a
sphere. A small part of a large sphere will form a high-directivity
(long-throw)
system with a
high SPL at a distance, whereas a large part of a small sphere will be of lower directivity
producing less SPL at a distance, but having a wider angle of coverage. This approach leads
to the creation of a virtual point source of sound somewhere behind the array.
There are some simple rules to follow to help achieve this goal:
♦
Never point two high packs in exactly the same direction.
♦
Try to obtain a smooth even curve in the horizontal plane.
♦
Use a similar amount of tilt on each column.
♦
Ensure that the bottom corners of each column are in line with each other.
