CRA24/ 30 array assembling 

 
The numbers in the text below, correspond with the CRA30 overview pictured earlier. 

 

The CRA24/ 30 system can be stacked onto a cinema screen frame. This is the default set-up. It is intended for 
indoor use only. 
The CRA30 system is scalable with 1x  1x CRA30N or 1x  2x CRA30N 
It is not possible to attach 2x CRA30W to each other. 
A stacked CRA24 system is scalable with 1x  1x CRA24N or 1x  2x CRA24N 
 
Mount two CRA30 stack feet (7) at both sides of the CRA30W cabinet. They can be screwed in place with  two 
M10x16 screws 
For scratch protection, place a carton sheet on top of the CRA30W cabinet and place the next CRA30N cabinet on 
this sheet, with the front corners aligned. This is a two man job. 
Attach the front couplers (5) and the angle arms (4) on bottom sides of the top CRA30N cabinet. Use the supplied 
M10 screws. They have a 8.8 strength class with a max. thread length of 16mm/ 0.63” 
Do not tighten up the screws at this moment. This gives more clearance when assembling the next cabinet. Attach it 
to the front couplers. Make the angle arm connection, with the correct angle adjustment. 
Repeat this mounting procedure with an optional second CRA30N cabinet. Tighten up all front coupler and angle arm 
screws. Tilt the complete array on the stack feet to the correct alignment (17° variable) and tighten these screws up 
firmly. The stack foot can be screwed to the screen frame for extra safety 
Connect all cabling to the signal input panels (6) and ensure that the cable weight is supported by a dedicated cable 
suspension.
