Change the acoustical center for both beams, placing the acoustical center for one beam at the top
of the array and the other one at the bottom.
Note that you can place the acoustical center of either beam 1 or of beam 2 at the top of the array.
In other words, either beam can be above or below the other one. In fact, both beams could have
their acoustical center at the same location.
The only difference is that the level of beam 2 can be reduced by inserting a negative value in the
Relative Level [Db]
field, while the level of beam 1 can not be changed. This ability to reduce the
level of beam 2 allows you to balance the SPL levels when the beams are covering different audi-
ence areas.
