HARDWARE SETUP PROCEDURE
Before proceeding with assembly of GEO S12 & LS18 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 & LS18 rigging system requires three experienced persons for
set-up: typically one motor hoist operator, and one 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 & LS18 Rigging System structural computations and related documents are available in NS-1
or at Nexo ([email protected]) upon request.
We include this section to remind you of safe practice when flying the GEO S12 & LS18 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 & LS18 loudspeaker systems. References in this
manual to other rigging equipment such as motor hoists, steels, shackles etc. are made to clarify the
description of rigging procedures. The user must ensure that operators are properly trained by other
agencies in the use of these items.
The GEO S12 & LS18 Rigging System has been optimised for the deployment of curved vertical or
horizontal tangent arrays of GEO S12 & LS18 loudspeakers. Angle adjustment between cabinets has
been limited to specific settings to ensure correct acoustic coupling.
The GEO S12 & LS18 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 & LS18
Rigging System and provided with suitable safety equipment should deploy GEO Arrays. Misuse of the
GEO S12 & LS18 Rigging System could lead to dangerous consequences.
Used and maintained correctly, the GEO S12 & LS18 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 GEO S12
& LS18 cluster. 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.
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 & LS18
Rigging System.
 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.
 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.
