NS-1 installation package includes all NEXO User Manuals, Structural Analysis Reports and Certificates PDF files. NS-1 is a freeware available on nexo-sa.com IMPORTANT Never install a GEO S12 EN54 cluster without checking its acoustical performances and mechanical safety in NS-1 prior to installation. -
Page 16: Configurable Directivity Device
CONFIGURABLE DIRECTIVITY DEVICE ONFIGURABLE IRECTIVITY EVICE 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). -
Page 17: When & Where To Use Configurable Directivity Flanges
CONFIGURABLE DIRECTIVITY DEVICE 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). -

We include this section to remind you of safe practice when flying the GEO S12 EN54 system. Please read it carefully. However, user must always apply his or her knowledge, experience and common sense. -
Page 19: Ground Stacking Safety
For fixed installations, wind loading has to be taken into account in accordance to the national standards. The GEO S12 EN54 Rigging System requires regular inspection and testing by a competent test centre. NEXO recommend that the system is load tested and certified annually or more frequently if local regulations require. -
