MOUNTING & RIGGING OPTIONS
Rigging Hardware & Accessories
The EMS-122 has six options for mounting and suspension, both for temporary use and permanent fixed
installation.
The EMS-122 contains four M10 threaded fixing points and a single M8 point around the enclosure, to enable
suspension using
forged shoulder eyebolts
(minimum thread length 20mm) or the optional flying hardware.
These fixings allow suspension in any orientation, with the extra point on the rear of the enclosure available for
pull-back to obtain the desired rigging angle or as a secondary safety point.
The EMS-122 also has four M8 threaded fixings on the rear for use with Omnimount Series 60 or Powerdrive Series
100 installation mounting hardware.
With any suspension method, a second anchor point should be used as a safety.
Under no circumstances should the mounting points of one enclosure be used to suspend another
enclosure below it. EM Acoustics are in no way responsible for the failure of incorrectly rigged
systems. This information relates specifically to the rigging techniques for the EMS-122/EMS-122w
enclosure only. If you are in any doubt about safe practices for rigging loudspeakers, please contact
your local EM Acoustics dealer who will be able to advise you.
Permanent Installations
Any installation (permanent or temporary) must be securely attached to the structure of the building using chain,
steel wire or web straps that are certified and load rated for the loudspeaker system. Consideration must be taken
when determining the loading on the structure to include loudspeakers and rigging hardware, and the appropriate
safety factor can then be decided upon.
If you are in any doubt whatsoever,
please contact your EM
Acoustics dealer who will be able to refer you to an experienced rigging company. A reputable rigging organisation
should also be able to advise on legislation regarding safety factors for suspended systems of this type.
Safety Considerations
When utilising any suspension method, a secondary safety must be used. For any suspension method, fit an M8
eyebolt to any of the rigging points. A safety steel can then be attached to this and connected to your safety
point.
If you are in any doubt whatsoever about how to safely suspend your loudspeakers, do not
hesitate to contact your EM Acoustics representative who will be able to refer you to a qualified
rigging company for advice.
