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 M10 are shipped in the 80° dispersion configuration, 120° CDD
TM
flanges are an optional accessory
(GMT-FLGM10).
To change dispersion in the non-coupling plane to 120°:
- Pull the lever to remove the grille on the side (attached with a sling);
- Position the CDD
TM
flanges on the waveguide output magnetic clips;
- Reinstall the grille and lock it with the lever
To remove the 120° CDD
TM
flanges:
- Pull the lever to remove the grille on the side (attached with a sling)
- Remove the CDD
TM
flanges from the waveguide output magnetic clips
- Reinstall the grille and lock it with the lever
NB: In case of GEO M10-I versions, proceed as above by removing the side grille screws
