dV-DOSC dV-SUB Manual V2.0 Nov 2001 87Stacking dV-DOSC on top of dV-SUBSThere are two options for stacking dV-DOSC: with, or without dV-BUMP.Procedure 1: Stacking without dV-BUMPWhen stacking on stages or risers, reduced downwards tilt requirements for the stacked dV-DOSCsystem may allow for the direct installation of dV-DOSC on top of dV-SUB without use of dV-BUMP.Two dV-ANGLESD (sub to dV-DOSC) angles are used for the front attachment points and two dV-ANGLESDP (sub to dV, positive tilt) are used for the rear attachment points of the first dV-DOSC.The dV-ANGLESDP angle bar provides tilt angles of 0 (dV-DOSC flat with respect to dV-SUB-furthest hole position), 1.75 (intermediate) and 3.75 degrees (tightly wrapped - minimum holeposition).Before stacking dV-DOSC, build the dV-SUB stack and physically secure the enclosures using dV-ANGLESS angles between cabinets (and/or a ratchet strap around the entire stack). Physicallysecuring dV-SUBs will provide extra stability during the dV-DOSC stacking procedure and will alsoprevent subs from moving during the show.With reference to the photo sequence that follows, pre-attach 2 x dV-ANGLESD at the front of thetop dV-SUB and 2 x dV-ANGLESDP at the rear using 4 x dV-PIN25. The closest holes on these anglebars are used for stacked applications and the ''fat'' part of the angle bars is oriented towards thecenter of dV-SUB in order to mate properly with the dV-DOSC rigging panels.The first dV-DOSC is inverted and placed in position by mating the rigging recesses on the dV-DOSCrigging panels with the pre-attached dV-ANGLESD and dV-ANGLESDP angle bars. Secure the fronttwo attachment points using 2 x dV-PIN25 then raise the dV-DOSC at the rear and select thedesired tilt angle on dV-ANGLESDP (0, 1.75 or or 3.75 degrees), again securing the two rear pointsusing 2 x dV-PIN25. Continue to build the stack by pre-attaching dV-ANGLE P1 or P2, pre-selectingthe desired tilt angle and securing with dV-PIN25 before installing additional dV-DOSC enclosures. |
