8 GEO S12 HARDWARE SETUP PROCEDURE
Before proceeding with assembly of GEO S12 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.
For maximum efficiency the GEO S12 rigging system requires three experienced persons for set-up:
typically one motor hoist operator, and one GEO S12 operator per side of the array. Good
synchronisation and crosscheck between the operators are key elements for a reliable and safe set-up.
8.1 SAFETY FIRST
GEO S12 Rigging System structural computations and related documents are available in Geosoft2 or
at Nexo ([e-mail]) upon request.
We include this section to remind you of safe practice when flying the GEO S12 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 GEO S12 loudspeaker systems. References in this manual to
other rigging equipment such as motor hoists, steels, shackles etc. are made to clarify the description of
GEO S12 procedures. The user must ensure that operators are properly trained by other agencies in
the use of these items.
The GEO S12 Rigging System has been optimised for the deployment of curved vertical or horizontal
tangent arrays of GEO S12 loudspeakers. Angle adjustment between cabinets has been limited to
specific settings to ensure correct acoustic coupling.
The GEO S12 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 GEO S12 Rigging System and
provided with suitable safety equipment should deploy GEO Arrays. Misuse of the GEO S12 Rigging
System could lead to dangerous consequences.
Used and maintained correctly, the GEO S12 Rigging System will give many years of reliable service in
portable systems. Please take the time to read and understand this manual. Always use GEOSoft2 to
determine the optimum angle settings for a particular venue, hang point and curved vertical GEO S12
cluster. Applied forces and moments are strongly cabinet quantity and angle configuration dependent.
Cluster configuration must be implemented and validated in Geosoft2 prior to installation.
8.1.1 Flown Systems Safety
• Always inspect all the rigging components and cabinets for damage before assembly. Pay
special attention to the lifting points, and safety clips. If you suspect that any of the components
are damaged or 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 GEO S12 Rigging System.
• Applied forces and moments are strongly cabinet quantity and angle configuration dependent.
Cluster configuration must be implemented and validated in Geosoft2 prior to installation.
• Ensure that all local and National regulations regarding the safety and operation of flying
equipment are understood and adhered to. Information on these regulations can usually be
obtained from Local Government Offices.
• When deploying a GEO S12 system always wear protective headwear, footwear and eye
protection.
• Do not allow inexperienced persons to handle a GEO S12 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.
