Fly bar suspension and angle setup (centre of gravity)
The figure at the side shows where the normal centre of gravity is with one
box or several boxes arranged in a line. Usually the boxes are arranged to
make an arc for the best coverage of the audience, so the center of gravity
moves backward. The aiming software suggests the ideal suspension
pinpoint taking into account this behaviour: fix the straight shackle in this
position.
Note that the ideal aiming angle often doesn’t correspond to the pinpoint:
there is often a little difference between ideal aiming and real aiming and
its value is the Delta angle: positive delta angle can be adjusted a little
using two ropes, negative delta angle are self adjusted a little because the
cables weight on the back of the array. With some experience it’s possible
to consider preventively these required little adjustments.
During the flown set up you can connect the elements of the array to their
cables. We suggest to discharge the weight of the cables from the flying
pinpoint by tying them with a textile fibre rope, instead of letting them hang
freely: in this way the position of the array
will be much more similar to the simulation
produced by the software.
Pin locking and splay angles set up
The figures below shows how to insert
correctly the locking pin, always carefully
check that each pin is fully inserted and
locked in the correct position. Set up the
splay angle between loudspeakers inserting
the pin in the correct hole, please note that
the inner hole in the hinge top is for whole
angles (1, 2, 3 etc.) while the outer hole is
for the half angles (0.5, 1.5, 2.5 etc.).
