6.2 When & where to use Configurable Directivity flanges
The diagrams show audience area coverage for a stereo system. While the GEO cluster will deliver even SPL from the front to
the rear of this audience area, there are “holes” near the front in the centre and at the outside edges. We cannot fill the outside
coverage gaps without enlarging the centre gap, and vice versa (left figure below).
If 120° Configurable Directivity Devices are installed at the bottom cabinet of the clusters, coverage will look more like the pattern
in right figure below.
- 6dB coverage, all GEO S12 in 80° configuration -6dB coverage, bottom GEO S12 in 120° configuration
In curved vertical arrays, the 120° Configurable Directivity Device can be used:
•
On the bottom row of curved vertical arrays, to fill in coverage gaps in the front rows.
•
On all rows of curved vertical arrays, in cases where 120° of horizontal coverage is preferred to 80°.
IMPORTANT
Installing or removing one of the two flanges anticipating asymmetrical coverage will degrade both
coverage and frequency response.
