3.6.2 OFFSTAGE FILL
Good candidates for offstage fill include dV-DOSC, ARCS, KUDO or additional V-DOSC arrays.
Selection between these options will depend on throw distance and vertical coverage requirements
and the guidelines outlined in multiple arrays should be followed (Section 3.3). For offstage fill, the
same principles for flown versus stacked systems apply (Section 3.2) and hybrid flown/stacked offstage
fill systems can also be effective. In some cases, a distributed approach can be adopted using tripod-
mounted MTD or XT coaxial enclosures to provide offstage plus rear fill coverage.

As discussed in Section 3.1, stacked systems improve image localization for the audience by lowering
the perceived image to stage level and, geometrically, a stacked system can provide more extended
vertical coverage than a flown system. For these reasons, stacked offstage fill systems or a hybrid
flown/stacked approach can be of interest for arena sound reinforcement - particularly for many of the
newer generation basketball arenas that are narrow with high vertical coverage requirements. Fewer
enclosures are required to obtain the necessary audience coverage vertically and there is less audience
shadowing since people are seated on a tribune gradient. As an additional benefit for stacked offstage
fill systems, the subjective image is lowered to stage level.
