COSMO Line Array – Instructions for use
5 Connecting Hardware and Curving
Arrays
5.1 General information on connections
Flown arrays
A three-point system serves to connect COSMO line array's M/H
units and rigging hardware. Two front-side, top and bottom
attachment points connect the front of the components. The
rigging hardware for the rear load line consists of an angle plate
and fl ap at the back each M/H unit.
Flap
The fl ap links the individual components and is always attached
to the angle plate of the bottom M/H unit in compressed or fi xed
mode. The M/H units may be tilted by up to 10° in 1° steps.
A four-point system without a tilt option serves to attach the
CF 118 subwoofer to the CRF-80.
Transport
Store and transport the M/H units at a 0° angle on the C-WB wheel
board. This way, you can connect the package of stowed M/H units
directly to the rigging frame in compressed mode for fast, easy
assembly by just one person. All loads are to be lifted by a chain
hoist.
In ground stacks
Connect individual components in ground stacks to each other in
fi xed mode. The M/H unit's fl ap attaches directly to the rigging
frame, to the C-GSA ground stack adapter, or to the angle plate of
the COSMO M/H unit below it.
5.2 Compressed mode vs. fi xed mode
Compressed mode
When rigging in compressed mode, fi rst set up the line array
at a 0° angle with the tilt of the individual M/H units preset on
the angle plate. Then angle the array by tightening the C-STR
tensioning to exert force on the pull-back frame.

Fixed mode
In fi xed mode, the individual parts are connected at a fi xed angle,
so you do not need a tensioning strap.
