Installation using KPTAX12C flybar
Using the
KPTAX12C
fly bar it is possible to assemble a suspended and unobtrusive vertical array system
with a variable size up to 4 elements of AX12C, or a combination of AX12C, AX6C and AX12LF without
exceeding the 120Kg maximum load capacity. The loudspeakers are linked together in a column using
the brackets integrated at each end of the enclosure. Each system can be set properly both acoustically
and mechanically using the aiming software.
Each loudspeaker box is fixed to the next one using the two locking pins. The locking pin in the front
does not require any adjustment, while the locking pin in the back is used to adjust the splay angle
between two adjacent loudspeakers in the array column at 0° or 2°.
Follow the sequence in the figure for fixing the flybar to the first box. Usually this is the first step before
lifting up the system. Be careful to insert properly the shackle (1)(2) and the locking pins (3)(4) in the
right holes specified by the aiming software.
When lifting the system always proceed gradually step by step, paying attention to secure the flybar
to the box (and the box to the other boxes) before pulling up the system: this makes easier to insert
properly the locking pins.
Also when the system is released down, unlock gradually the pins.
The centre of gravity of an AX12C/AX6C/AX12LF array depends on the number of units and on the
splay angle between the units, when the units are arranged to make an arc for the best coverage of the
audience. Use always the aiming software to define the correct suspension pinpoint where to fix the
straight shackle and the optimal splay angle between units.
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
weights 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, for
this reason a ring is present at the end of the flybar that can be used to fix the cable 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.
Wind loads
When planning an open-air event it is essential to obtain current weather and wind information. When
loudspeaker arrays are flown in an open-air environment, possible wind effects must be taken into
account. Wind load produces additional dynamic forces acting on the rigging components and the
suspension, which may lead to a dangerous situation. If according to the forecast wind forces higher
than 5 bft (29-38 Km/h) 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 support double the static load in
order to withstand any additional dynamic forces.
WARNING!
Flying loudspeakers overhead at wind forces higher than 6 bft (39-49 Km/h) is not
recommended.
If the wind force exceeds 7 bft (50-61 Km/h) 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 person remains in the vicinity of the array.
- Lower and secure the array.
WARNING!
AX6C, AX12C and AX12LF must be suspended only using the flying bar KPTAX12C, with a
maximum of 120Kg per flying bar.
