Rigging Dv-Dosc Under Dv-Sub (Larger Configurations); Procedure 1 (2 Dv-Sub + 6 Dv-Dosc) - L-Acoustics dV-DOSC Operator's Manual

Rigging dV-DOSC Under dV-SUB (larger configurations)

When rigging larger configurations of dV-DOSC under dV-SUB (e.g., 2 dV-SUB with 6 dV-DOSC
underneath), there are 2 possible procedures: 1) fly the system in the same manner as dV-DOSC
standalone, i.e., assemble the enclosures face down on the ground and fly the system as a whole or 2)
follow the dV-SUB standalone rigging procedure then fly dV-DOSC in blocks of three.
For both procedures, refer to the photo sequences below in addition to the following descriptions:

Procedure 1 (2 dV-SUB + 6 dV-DOSC)

dV-SUB enclosures are located at the rigging location (face down on their dolley boards) and four dV-
ANGLESD are pre-attached to the dV-SUB using 4 x dV-PIN25 (in preparation for attaching dV-
BUMP). The ''fat'' part of the dV-ANGLESD is oriented towards the center of dV-SUB on both sides.
Note: Since there are no stacking runners on the top of dV-SUB, it is possible to select the stacked
hole position on the dV-SUB end of dV-ANGLESD.
Place dV-BUMP or dV-BUMP2 in position (oriented so that the rear extension bar is facing upwards)
and secure using 4 x dV-PIN25. If desired, attach the extension bar to dV-BUMP using an 18 mm
shackle at pick point #8 on the central spreader bar section. The extension bar allows the use of two
motors for tilt adjustment or single point hangs from the 8 additional points available on the extension
bar. If the extension bar is not used, 8 pick point positions are available on the central spreader bar
section of dV-BUMP for single point hangs.
Pre-attach 4 x dV-ANGLESS on the second dV-SUB enclosure (still face down on its dolley) then
physically connect to the first dV-SUB using 8 x dV-PIN25 total.
Pre-attach 2 x dV-ANGLESD at the (bottom) front and 2 x dV-ANGLESDP at the (bottom) rear of the
second dV-SUB using 4 x dV-PIN25. Recall that the outermost holes on these angle bars are used for
flown applications (to provide clearance for the stacking runners) and that the ''fat'' part of the angle
bars is oriented towards the center of dV-SUB in order to mate properly with the dV-DOSC rigging
panels.
Line up all dV-DOSC enclosures in their flight cases (3 per case). Mate the bottom rigging tabs from
the first group of 3 cabinets with the top locator slots of the next group of cabinets. Repeat until all
dV-DOSC flight cases are physically lined up.
Physically connect the fronts of all dV-DOSC enclosures by attaching the front points using pairs of
dV-PIN25. The entire assembly will then be linked, similar to how V-DOSC is attached using rotating
legs and U-pins (except the attachment points are at the front in this case).
Referring to the angle values that were pre-calculated for each enclosure using ARRAY2004 or
SOUNDVISION, pre-attach pairs of dV-ANGLE bars at the rear of all dV-DOSC enclosures of the
array (while they are still face down in their flight cases). Remember to keep the ball / tab end up as a
reference and be careful to select the correct angle for each enclosure (generally, it is better if one
person performs this operation to avoid mistakes).
Pre-connect the front and rear points for the first dV-DOSC to the dV-SUB, using 4 x dV-PIN25. Do
not connect the rear of dV-DOSC #2 to #1 (this will be done as the system is flown). Do connect the
rear of dV-DOSC #2 to #3.
Note : Selecting the 0 degree angle on dV-ANGLESDP (between the rear of the top dV-DOSC enclosure and
dV-SUB) is necessary to compensate for the 3.75 degree trapezoidal angle of dV-DOSC versus the actual
site angle of the enclosure which is perpendicular to the front. Selecting the 0 degree angle allows focus to
be verified visually or with a laser attached to the bottom of dV-SUB since this will then be referenced to the
actual site angle of the top dV-DOSC enclosure.
Except for the first block of 3 dV-DOSC, connect the rears of all other dV-DOSC enclosures in blocks
of three (while they are still face down in their flight cases) by pulling the cabinets together at the rear
and inserting dV-PIN25. This operation is facilitated by the fact that all fronts are pinned together and
can pivot, plus all rear angles were pre-attached.
