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 M12 are shipped in the 80° dispersion configuration, 120° CDD
(GMT-FLGM12).
To change horizontal dispersion from 80° to 120° and vice-versa:
-
Pull the lever to remove the grille on the side on touring version
-
Or unscrew the 4 Tx25 to remove the grille on installation version
-
Position the CDD
-
Reinstall the grille and lock it with the lever (touring version) or the screws (installation version)
