MG-MINA/LINA/750-LFC GRID ASSEMBLY GUIDE

750-LFC GUIDEALINKS

When equipped with the MRK-750 rigging kit, the 750-LFC includes six captive GuideALinks and six mating link slots that 
link to adjacent units in flown and groundstacked arrays. Located at the bottom of the cabinet, GuideALinks drop down and 
into the link slots of the cabinet below it. GuideALinks extend and retract with knobs and are secured with two quick-release 
pins: one each in the top and bottom cabinets. GuideALinks accommodate reversed units for cardioid arrays. The MRK-750 
rigging kit includes ten loudspeaker quick-release pins (0.25 in x 0.53 in, black button, PN 134.039

)
