5. Safety Checks
Before the array is hoisted to its
fi
nal trim height some safety checks should be made.
These checks apply to either
fl
own or ground stack con
fi
gurations.
5.1. Mechanical Safety
Check the attachment of the hoist to the frame. Ensure shackles are tightened
correctly.
Check the attachment of the secondary safety device on the frame and ensure
shackles are tightened correctly.
Check the attachment of the
fl
ying frame to the cabinet below and ensure all locking
pins are seated correctly and locked.
Check the attachment of all the front links on both sides of the cabinets and ensure
all locking pins are seated correctly and locked.
Check the splay angles on the rear of all cabinets and ensure all locking pins are
seated correctly and locked.
In “single pickpoint operation” check the desired vertical angle of the entire array by
using an inclinometer attached to the frame.
5.2. System Wiring
Check that all cables on the back of the array are seated correctly and connected
to the correct ampli
fi
er channels.
Check the cable pick on the frame is attached securely and all the cables are choked
and supported by the frame so as to not put any undue stress on the connectors.
Up to two CORA-S may be connected in parallel per ampli
fi
er channel.
Up to two CORA (passive) array cabinets may be connected in parallel per ampli
fi
er
channel.
CORA Active: Up to three x CORA-A (active) cabinets may be connected together with

5.3. Signal Tests
Once the system is set up, wired and powered on, use a signal generator connected
to a mixing console to check the status of each loudspeaker component in the array.
