CRA24 array assembling
The numbers in the text below, correspond with the CRA24 overview pictured earlier.
The CRA24 system is preferably suspended from a truss girder or cinema screen frame. This is
the default set-up. It is intended for indoor use only.
The system is scalable with a maximum of 3 cabinets:
1x CRA24N + 1x CRA24W
2x CRA24N + 1x CRA24W
1x CRA24N + 1x or 2x CRA24WX
2x or 3x CRA24WX
It is not possible to attach 2x CRA24W or CRA24W and CRA24WX under each other.
Mount two shoulder eye bolts (4) on the top CRA24N(WX) cabinet. They can be screwed in place
when the two (top) cabinet screws have been removed.
Attach the front couplers (8) and angle arms (6/7) on bottom sides of the cabinet. Use the
supplied M8 screws. They have a 8.8 strength class with a max. thread length of 12mm/ 0.47"
Do not tighten up the screws at this moment. This gives more clearance when assembling the
next cabinet. Hold the next cabinet under the first, this is a two man job and attach it to the front
couplers. Do not let it hang under its own weight, because this will damage the HF horns! Make
the angle arm connection, with the correct angle splay adjustment.
Repeat this mounting procedure with the last CRA24W(WX) cabinet. Mount the shoulder eye bolt
on the centre rear mounting of this cabinet. Tighten up all screws.
Connect all cabling to the signal input panels (9) and ensure that the cable weight is supported by
a dedicated cable suspension.
Hoist the assembled array up to the correct position and use the rear shoulder eye bolt to adjust
the tilt angle of the array.
The picture on the right shows a side view of an assembled 3pc CRA24 array.
