SUSPENSION SAFETY WARNINGS! Correct use of all rigging hardware is required for secure system suspension. Careful calculations should always be performed to ensure that all components are used within their Maximum Load Limit before the array is suspended. Never exceed the maximum recommended load ratings. Prior to suspending the system, an expert, trained and experienced in flying speaker systems should be consulted. - Page 19 MAXIMUM ARRAY SIZE There are two variations of the MG array frame. The MG-AF is for suspension of MG1918S and MG1932. The MG-SMAF is solely intended for use with the MG1928 and MG1915S. Before suspending an MG array, determine which version of the array frame you have and consult the table below to determine the maximum number of speakers that may be safely suspended.
- Page 20 SUSPENSION IN PERMANENT INSTALLATIONS For permanent installation applications an MG array may be suspended using M10 eyebolts. Only load-rated, forged shoulder eyebolts are to be used. A kit consisting of three (3) forged shoulder eyebolts is available from JBL Professional as part number 229-00009-01. Suspension of the MG array must employ both top attachment points.
