9 Setting Up Ground Stacks
Heads up: Be sure to set the ground stack on a fi rm
surface and secure it to keep it from tipping.
Heads up: Setting up and tearing down ground stacks can
be dangerous. People may get hurt and property damaged
if the stack moves in unexpected ways or is improperly
assembled and disassembled.
Make sure quick-release pins, shackles and all other
connecting components are properly engaged and secured
to prevent them from loosening.
Wear suitable protective headgear,
gloves and footwear when assembling and disassembling
the array.
The CS 118, CS 218 and CF 118 subwoofers serve as the base for
ground stacks. M/H units may be tilted at +2°/0°/-2° angles using
the CRF-80 and CRF-60 rigging frames. If you need to tilt speakers
further to aim them, you can use the optional C-GSA ground stack
adapter to set larger angles from -6° to -20°. You can also use the
CRF-PB pull-back frame for a ground stack. See section 9.4 for
more on this.
Heads up: Make sure the ground stack's center of
gravity remains within the base. Always secure the ground
stack to prevent tipping.
