Rigging and suspension 
 

 

 

 

 

Before  rigging  or  suspending  NEXT  LA122/LA122W  systems

inspect  all 

components  and  all  hardware  for  any  signs  of  damage  or  missing  parts.  If  you  find  any 
damaged, corroded or deformed parts, do not use them, replace them immediately. Do not 

use  hardware  that  isn’t  load  rated  or  that  its’  rating  is  not  enough  to  handle  the  system’s 
weight with a good safety factor. Don’t forget that the hardware won’t just hold the systems 
weight.  It  has  to  be  sturdy  enough  to  handle  dynamic  forces  like  winds  without  any  part 
deformation. NEXT-Proaudio advises customers to contact a licensed, professional engineer 

regarding equipment installation.  
 

NEXT LA122/LA122W system installation should only be carried out by qualified 

personnel.  Always  use  adequate  protective  clothing  and  equipment  to  prevent  possible 

injuries. Only install the systems on solid, levelled ground and isolate the surrounding area 
during installation and operation, to prevent general public presence near the systems. Also, 
be  sure  you  understand  all  local  and  national  regulations  regarding  equipment  installation. 

Failure to comply with these instructions may result on injury or death. 
 
 

UNPACKING 

 
 

Each  NEXT

 

LA122/LA122W  line-array  element  is  built  in  Europe  (Portugal)  by 

NEXT-Proaudio,  to  the  highest  standard  and  thoroughly  inspected  before  it  leaves  the 
factory.  When  unpacking  the  NEXT  LA122/LA122W,  examine  it  carefully  for  any  signs  of 
possible transit damage and inform your dealer immediately if any such damage is found. 
 

It is suggested that you retain the original packaging so that the system can be 

repacked  in  the  future  if  necessary.  Please  note  that  NEXT-Proaudio  and  its  authorized 
distributors cannot accept any responsibility for damage to any returned product through the 
use of non-approved packaging.
