Flying

Never implement a bridled suspension on the WIFOBUMP frame or on two WIFOLIFT bars.
Always use 1 load-bearing line per pick-up point.
Forthcoming: An additional rigging element interfacing 2 WIFOLIFT bars with a single load-bearing line will
be released in the near future.
Truss clamping
By installing a CLAMP250 instead of a shackle, an array can be attached to a truss. Refer to PROCEDURE B.
Pullback implementation
By using rigging points at the rear of the installed coupling bars, an ARCS
array can be implemented in pullback configuration. Refer to APPENDIX.A
Final check before flying the system
Coupling bars: All lugs of locking tabs must be secured, as indicated in PROCEDURE A.
Shackles : All safety pins must be secured as indicated in PROCEDURE B.
Choose the flying option before rigging the system
Identify the appropriate flying option and rigging hole(s) by modeling the system in SOUNDVISION.

Horizontal
Place enclosures (WIDE or FOCUS) in vertical position, side-by-side and rails aligned
Remove all the WIFORIG bars from their storage location
Install the WIFOLIFT bar(s)
Refer to PROCEDURE A
Slide and lock WIFORIG bars into all top remaining adjacent rails
Refer to PROCEDURE A
Attach a shackle on each of the required WIFOLIFT bars
Refer to PROCEDURE B
Slightly raise the array until its bottom is at waist height
Slide and lock WIFORIG bars into all bottom adjacent rails
Refer to PROCEDURE A
Vertical
Place the first enclosure (WIDE, FOCUS or SB18m) on the floor
For an array with 2 SB18m, place and lock a second SB18m on top of the first one
Refer to PROCEDURE A to lock the SB18MRIG bars
Remove the coupling bars from their storage location
Place the WIFOBUMP frame on the top enclosure and lock the coupling bars
With SB18m on top, refer to SOUNDVISION for the frame position (front or rear)
Refer to PROCEDURE A to lock the coupling bars
Attach a shackle on the WIFOBUMP
Refer to PROCEDURE B
Slightly raise the array until its bottom is at waist height
Bring the next enclosure and remove the bars from their storage location
Lift and attach the next enclosure under the array
Refer to PROCEDURE A to lock the coupling bars
To add more enclosures, repeat the previous 3 steps until the array is completed
