3. Preparation
3.1. General preparations
Check the acoustical and mechanical set up with the ArrayCalc array
calculator and prepare enough print outs for each array.
Using the plan, the riggers are able to set up the suspension points, the
securing points and the chain hoists.
The working load limit of the chain hoists and their
suspension points has to be high enough to carry the
total system weight.
As during a dual hoist set up the motors might not
always be synchronized each of the suspension points
has to be able to carry the total system weight.
When on site first clear the working areas, check that the hoists are
exactly in the specified position, the chains are not twisted and there is
enough space to set up and lift the array.
3.2. Inspections
All system components must be inspected for faults before use. This also
includes the loudspeaker and in particular the rigging parts of the
cabinets.
WARNING!

3.5.2. Single hoist set up
When suspending the array from a single pick point (Single Pick point
Operation) the following limits apply:
Maximum system weight of 1025 kg (2260 lb) or
accordingly:
• Max. 16 x J-TOP cabinets (J8/J12)
• Max. 8 x J-SUB cabinets
In "Single Pickpoint Operation" the position of the J Load adapter
defines the vertical aiming of the whole array.
The corresponding hole position is calculated using ArrayCalc (Fig. 16)
and can be set in a 1/2-hole resolution at the top of the center bar of
the J Flying frame.
The J Load adapter allows a full grid (1/1 Pickpoint Detent) or a half
grid (1/2 Pickpoint Detent) setting depending on its direction of
attachment (Fig. 17/18).
The frame's hole index marked on one side of the center bar of the
frame is the reference for the direction of the Load adapter.
Attaching the Load adapter
1. Choose the appropriate hole position in the J Flying frame center
bar according to the ArrayCalc simulation and attach the J Load
adapter correspondingly.
If ArrayCalc displays a half numbered hole setting (half grid) turn
the J Load adapter correspondingly (refer to Fig. 18)

2. Connect the Z5305 J Hoist connector chain to the 3.25 t Shackle of
the J Load adapter.
3.5.3. Dual hoist set up
When suspending the array from two pick points the following limits
apply:
Maximum system weight of 1.5 t (3300 lb) or accordingly:
• Max. 24 x J-TOP cabinets (J8/J12)
• Max. 14 x J-SUB cabinets
With Dual hoist setup the vertical aiming of the array will be set by
trimming the hoist motors after the array is fully assembled and lifted to
its operating position. The corresponding hole positions of the Load
adapters is calculated using ArrayCalc - Fig. 20.
Attaching the Load adapter
1. Choose the appropriate hole positions for the Front and Rearpick in
the J Flying frame center bar according to the ArrayCalc simulation
and attach the J Load adapters correspondingly (Direction: Full grid
1/1 Pickpoint Detent).

WARNING!
WARNING!
If according to the forecast wind forces higher than 5 bft
are possible the following actions have to be taken:
•••• The actual on site wind speed has to be monitored
permanently. Be aware that wind speed typically
increases with height above ground.
•••• Suspension and securing points of the array should be
designed to accommodate double the static load in
order to withstand any additional dynamic forces.
If the wind force exceeds 8 bft there is a risk of
mechanical damage to the components which may lead
to a dangerous situation for persons in the vicinity of the
flown array.
Stop the event and make sure that no one is left within
the vicinity of the array.
Lower down and secure the array.
