provided with two connector sockets for direct connection and for paralleling of up to three
enclosures (using DO.7 V-CABLEs).
The rectangular shape of the enclosure allows for easy stacking, transport and handling. A front
mounted dolly board is provided for protection and transportation. Stacking runners located on the
bottom of the cabinet act as skid pads to protect the cabinet finish and mate with stacking runner
recesses on the top of the enclosure for enhanced stability when stacking. Cabinet dimensions are 130
cm (51.2-in) wide, 43.4 cm (17.1-in) high, 56.5 cm (22.2-in) deep and were designed to allow for
efficient truck packing for a variety of trailers of standard size. Enclosure weight is 108 kg (238.1 lbs)
and cabinet construction consists of 15 mm (0.59-in), 30 mm (1.18-in) Baltic birch plywood with
internal steel bracing and joints that are sealed, screwed and rabbeted. The finish is maroon-gray,
high-resilient paint and the front of the enclosure is protected by a black epoxy-coated, 1.5 mm (0.06-
in) thick steel grille that is covered with 10 mm (0.4-in) thick acoustically-transparent open cell foam.
Flying a V-DOSC array is easy, fast and secure. The V-DOSC enclosure features a unique rigging
system where built-in flying hardware extends from cabinet-to-cabinet to the hanging points on the
BUMP2 flying structure in a train-like fashion. Two recessed Aeroquip flytrack sections are mounted
on both sides of the enclosure and two rear-mounted rotating legs allow up to 16 V-DOSC to be
assembled in a vertical column. Angle straps are attached between enclosures using the side flytrack
sections to provide up to a maximum of 5.5 degrees between enclosures at 0.75 degree angular
resolution. Cabinets are physically connected while lined up on the floor and the complete array is
flown all at once (in comparison with other systems where cabinets are flown row-by-row). The only
external parts needed are ANGLE STRAPS and SPACER blocks – these accessories are used to adjust
the angle between enclosures in the array (see Chapter 4 for details on flying and stacking V-DOSC).
V-DOSC is used with an approved digital signal processor with OEM factory presets for active 3-way,
4-way or 5-way operation in conjunction with additional SB218 or dV-SUB subwoofer enclosures.
1.3 V-DOSC RIGGING SYSTEM
Figure 18: V-DOSC BUMP2
The BUMP2 flying structure consists of a rectangular steel main frame with heavy duty cross bracing
and comes supplied with the following rigging accessories: 3x 22 mm shackles (CA MAN22), 1x steel
sling (0.65 m), 4x screwjacks (MC_DOPIED), 2x ratchet straps (16 metre length), 2x BUMPER angle
straps (BUMP23) and 2x U-PINS (MC_DOAXE). The two rotating legs located on the bumper along
with U-shaped locking pins are used to attach the first V-DOSC enclosure of the array when either
flying or stacking. Two side-mounted Aeroquip flytrack sections allow for attachment of the first V-
DOSC enclosure to BUMP2 using the BUMPER angle strap.
When rigged, the BUMP2 is hung from two points spaced by 1.05 m (43 ¼”) - one front and one rear.
The center of gravity of the whole array is exactly vertical from the line joining these two points.
Motors can be attached to the central hole locations on the bumper or for additional safety factor
when flying larger arrays, the two outer hole locations (front and rear) can be used for bridling using 4
steel slings (2 front, 2 rear), 8 shackles and 2 pear rings.
