1.3 dV-DOSC RIGGING SYSTEM
dV-DOSC features a convenient rigging system where rear mounted angle bars are used to control
the angle between enclosures, i.e., cabinets pivot about the front mount points and selecting the
desired hole on the rear angle bars adjusts the angle between enclosures. When dV-ANGLE P1 or P2
bars are used, convex (positive curvature) arrays can be constructed ranging from flat up to a
maximum of 7.5 degrees between cabinets in increments of approximately 1 degree.

dV-BUMP or dV-BUMP2 bumpers are used for rigging dV-DOSC standalone or flown below dV-SUB
and for a variety of stacking applications. There are 8 pick point holes available on the central spreader
bar section of both bumpers for single point hangs (pick point hole numbering is 1-8 from front to
rear). An extension bar can be added to provide an additional 8 pick points for single point hangs (pick
point hole numbering is 9-16 from front to rear) or to allow for 2 point hangs with front and rear
motors. For 2 point hangs, the front motor controls the array trim height while the rear motor
controls the array site angle.
For a tightly wrapped array of 12 dV-DOSC, 90 degrees vertical coverage is obtained. For this case,
when the rear-most point on the extension bar is used for a single point hang, the 90 degree coverage
runs from parallel to the floor to perpendicular to the floor.
Note: For single point hangs, the array site angle will depend on the size and shape of the array since these
factors alter the center of gravity of the overall flown system.
dV-BUMP also allows for three different stacking options:
1) stacking platform with variable tilt adjustment for stacked dV-DOSC applications;
2) stacking platform for rigging dV-DOSC on top of V-DOSC;
3) stacking platform for rigging dV-DOSC on top of subwoofers.
Note: Options 1) and 2) are achieved by mechanically connecting dV-BUMP to the V-DOSC
BUMPER.
