Page 3: Introduction
1. Introduction __________________________________________________ Dear customer, Congratulations on your purchase of an Alcons Audio LR24 line array loudspeaker and thank you for your confidence in Alcons products. We are very honoured to welcome you to the growing family of Alcons ambassadors! For your safety, please read the Important safety instructions and the precautions section before rigging a loudspeaker array. -
Page 4: Important Safety Instructions And Precautions
Do not stack the loudspeaker array on unstable ground or surface. If the array is stacked on a structure, platform, or stage, always check that the latter can support the total weight of the array. As a general rule, Alcons Audio recommends the use of safety straps at all times. -

Rigging components __________________________________________ GRD24B The GRD24B enables the LR24 line-array modules to be flown and ground stacked. The grid can be suspended from multiple hoist options on top of the grid or with the central “single pick-point” bar for smaller arrays (all points 14mm/0.55-in for 1,5T shackles).The...

The GRD24B has multiple mounting options. The picture on the left shows the different pick-points for flying an array. The A1 & A2 marked points are the default hoist points. It is also possible to use one pick point from the A1 linear pattern. Use it only for max. 12x LR24. Use two hoists at any time. This is safer and easier for array building... - Page 11 When ground stacking (e), ensure that the centre of gravity is well within the grid’s base area. single point hangs can be done but are not recommended with LR24 due to safety and array building complications.

- Page 12 5. Array configurations ___________________________________________ LR24 transport and array building options Curved pack/ Fly mode: All LR24 cabinets are connected vertically in a curved pack. This saves building space and enables Pre-flight angle-setting. All red pins are stowed in their parking holes. The bottom cabinet is mounted to the PRRGL24 according to the picture on the right.
- Page 13 5. Array configurations ___________________________________________ LR24 transport options Straight pack/ compression mode: All LR24 cabinets are connected vertically in a straight pack. This saves building space and enables pre-flight angle-setting. All red pins are placed in the angle arm hole. Except the angle arm of the top cabinet.

Array configurations ___________________________________________ Fly mode array assembling and hoisting The numbers in the text below, correspond with the LR24 loudspeaker overview pictured earlier. Shown on the right depicts array building in Fly mode style. Shown with 2 hoists, 1x GRD24B and 8x LR24 cabinets.

- Page 16 This flying option is best suited for small 4->12 pcs arrays. The cabinets are transported in a straight pack. The red buttoned pin (9) is crucial in this situation. It ensures that the cabinets (1) will stay in a 0° position. The angle arm can be adjusted while this pin is in position or “0° hole”. Rigging manual LR24 Rev. 1.1...
- Page 17 Do not over-compress the array, as this can cause damage to the suspension system ! After the compression stage, the angle of the entire array can now be adjusted. Use an angle inclinometer on the GRD24B. Rigging manual LR24 Rev. 1.1...

- Page 19 This can be determined by the Alcons Ribbon Calculator™ simulation program. In most cases a pack of LR24’s is sufficient. In this case the system will be in compression mode, with the red pins on the angle frame. Set all angles to the desired setting.
- Page 20 This can be determined by the Alcons Ribbon Calculator™ simulation program. Start disassembling an LR24 pack on a PRRGL24 or use single LR24’s. Turn the cabinets 180° in the vertical plane and connect the first one to the GRD24B.
