5 CONFIGURABLE DIRECTIVITY DEVICE
The GEO Wavesource controls dispersion of acoustic energy using a hyperboloid acoustical reflector in the “coupling plane”
(the vertical plane of a curved vertical tangent array) and a diffraction slot in the “non-coupling plane” (the horizontal plane of a
curved vertical tangent array). The patented Configurable Directivity Device consists of flanges that alter the diffraction slot’s
exit flare rate.
5.1 Installing & removing GEO’s Configurable Directivity Devices
GEO S12 are shipped in the 80° dispersion configuration, 120° CDD
TM
flanges are an optional accessory (GPT-FLG).
To change horizontal dispersion from 80° to 120° and vice-versa:
- Remove the front grille
- Remove the 6 screws from the waveguide
- Position the CDD
TM
flanges on the waveguide and fix it with the provided screws and washers
- Reinstall the grille
