Before proceeding with assembly of GEOS / CD12 arrays, please ensure that the components are present
and undamaged. A component list is appended to this manual. In the event of any shortage, please contact
your supplier.
SAFETY FIRST
GEO S8 / CD12 Rigging System has been approved by Certification Organization RWTÜV. Structural
computations, test reports, certificates are available in NS-1 or at Nexo (
) upon request.
We include this section to remind you of safe practice when flying the GEOS / CD12 system. Please read it
carefully. However, user must always apply his or her knowledge, experience and common sense. If in any
doubt, seek advice from your supplier or NEXO agent.
This manual offers guidance only for GeoS / CD12 loudspeaker systems. References in this manual to other
rigging equipment such as motor hoists, steels, shackles etc. are made to clarify the description of GeoS /
CD12 procedures. The user must ensure that operators are properly trained by other agencies in the use of
these items.
The GEO S8 / CD12 Rigging System has been optimised for the deployment of curved vertical tangent arrays
of GEO S805 / S830 / CD12 loudspeakers. Vertical angle adjustment between cabinets has been limited to
specific settings to ensure correct acoustic coupling.
The GEOS / CD12 Rigging System is a professional precision tool set, and should be handled with extreme
care. Only persons who are fully conversant with the operation of the GEOS / CD12 Rigging System and
provided with suitable safety equipment should deploy GEO Arrays. Misuse of the GEOS / CD12 Rigging
System could lead to dangerous consequences. Please refer to the safety section of this manual for advice
concerning GEOS / CD12 Rigging System installation and handling.
Used and maintained correctly, the GEO S8 / CD12 Rigging System will give many years of reliable service in
portable systems. Please take the time to read and understand this manual. Always use NS-1 to determine
the optimum angle settings for a particular venue, hang point and curved vertical GEOS / CD12 array. Applied
forces and moments are strongly cabinet quantity and angle configuration dependent. Cluster configuration
must be implemented and validated in NS-1 prior to installation.
Flown Systems Safety
• Always inspect GEO S8 / CD12 Rigging System components for damage before assembly.
Pay special attention to lifting points and safety clips. If you suspect that any of the
components are defective DO NOT USE THE AFFECTED PARTS. Contact your supplier
for replacements.
• Read this manual carefully. Also be familiar with the manuals and safe working procedures
for any ancillary equipment that will be used with the GEOS / CD12 Rigging System.
• Ensure that all local and National regulations regarding the safety and operation of flying
equipment are understood and adhered to. Information on these regulations may usually be
obtained from Local Government Offices.
• When deploying the GEOS / CD12 Rigging System always wear protective headgear,
footwear as well as eye protection.
• Do not allow inexperienced persons to handle the GEOS / CD12 Rigging System.
Installation personnel should be trained in loudspeaker flying techniques and should be fully
conversant with this manual.
• Ensure that motor hoists, hoist control systems and ancillary rigging components are
currently certified as safe and that they pass a visual inspection prior to use.
• Ensure that public and personnel are not allowed to pass beneath the system during the
installation process. The work area should be isolated from public access.
