Rigging concept and components
2.4 Rigging mechanism of the cabinets
The cabinets are mechanically connected to the Mounting frames/
Mounting adapter and subsequent loudspeakers using the Front
links attached to both sides of the front rigging strands of the
cabinets and the central Splay/Rear link on the rear rigging strand
of the cabinet.
All necessary rigging components are mounted to the cabinets and
slide or fold out when needed.
In principle, the Front link mechanism applies to both the TOP and
SUB cabinets. The Front links are spring loaded and therefore
extend automatically as soon as the respective Locking pins are
released and pulled out.
2.4.1 Front link mechanism
TOP cabinets
1. Release both Locking pins.
↳The Front link extends automatically.
2. Reinsert Locking pin [1] into the upper hole.
↳Locking pin [2] is used to connect the first cabinets to the
frame and/or to interconnect the cabinets respectively.
SUB cabinets
ÞRelease the upper Locking pin.
↳The Front link extends automatically.
The Front link mechanism of the SUB cabinets provides four
different settings:
1. SUB to Frame (Þ Fig. 1).
2. SUB to SUB with 0° splay between the cabinets (Þ Fig. 2).
3. SUB to SUB with 2.5° splay (free) between the cabinets
(Þ Fig. 3).
4. SUB to SUB with 2.5° splay (blocked) between the cabinets
(Þ Fig. 4).
This setting is used to prevent the cabinets from folding up.

2.4.2 Splay/Rear link mechanism
TOP cabinet
1. Release both Locking pins holding the Splay link in its park
position.
2. Fold out the Splay link.
SUB cabinet
The Rear link of the cabinet is kept in its park position by a spring
loaded fixing device.
ÞSlide the fixing device upwards to release the link.
2.4.3 Setting splay angles for XSL TOP cabinets
Tension mode rigging
The splay angles are set on the central rear rigging strands of the
cabinets. The angles between adjacent cabinets can be set in the
range from 0° to 14° in 1° increments.
In connection with the XSL Top mounting frame, the cabinets are
interconnected in tension mode.
The rear rigging strand of the cabinets provides three hole grid
columns.
For tension mode rigging, the center and outer columns are used to
set the desired splay angles from top to bottom of the columns,
while the center column applies to the
even and the outer column
to the odd angle settings.
The following Locking pin convention applies:
Pin [1] In tension mode, pin [1] is used to preset the splay
angle of a certain cabinet on the center and/or outer
hole grid of the cabinet itself.
Pin [2] During hoisting, the Splay link of the upper cabinet
engages and safety pin [2] is inserted in the hole
directly below.
Pin [3] In tension mode, pin [3] is always inserted in the
0° hole at the bottom of the inner hole grid to fix the
Splay link in place.
As an example, the graphic opposite shows the pin settings for
2° splay in tension mode.
Splay/Rear link mechanism TOP | SUB cabinets
d&b Z5778/Z5779 Rigging manual 1.2 en14

Rigging concept and components

Suspension of the frames
The center bars of the mounting frames are equipped with a hole
grid allowing either single or dual pickpoint suspension using the
enclosed 1 t shackles.
With single pickpoint suspension, the position of the shackle
defines the vertical aiming of the entire array.
The corresponding hole position is calculated using ArrayCalc.
3.1 Z5147 Rota clamp option
NOTICE!
Load safety information
A maximum of 12 x TOP cabinets (total system weight of 500 kg/
1100 lb - SWL) can be suspended with any splay angle
combination according to the ArrayCalc calculation.
Alternatively, the array can be suspended and horizontally aligned
from a single pickpoint using the d&b Z5147 Rota clamp. The
clamp allows the load to be attached to overhead bars or truss
