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

Flying 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 elements while they are 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)

The 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 the dV-BUMP into position on the dV-SUB and secure using 4 x dV-PIN25. The dV-BUMP is
oriented so that the dual locating studs are facing upwards (or rear extension bar upwards). 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 element using ARRAY 2000, pre-
attach pairs of dV-ANGLE bars at the rear of all dV-DOSC elements 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 element (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 element.
