Flying Guidelines - L-Acoustics dV-DOSC Operator's Manual

Flying Guidelines

For single point hangs, the flying system is rated for a maximum of 24 dV-DOSC elements
without the extension bar and 12 dV-DOSC elements with the extension bar.
Particular attention must be paid to the height at which the array is flown when predicting the
vertical coverage in ARRAY 2000 (Cutview). One will discover that in many cases it is easier to
optimize coverage at a certain height versus any other height.
Note that the angular configuration of the array should not be adjusted by considering the on-axis
cutview alone – always consider the audience geometry off the main axis, especially from 45° to 60°
off-axis (on the shorter throw side). Be sure to check that you are not lacking in offstage coverage
and require additional fill systems.
It is quite common to have venues where there are two sections of the audience area that have two
different slopes. In this case, coverage of the areas which are close to the borderline must be
determined carefully and dV-DOSC arrays should be focused differently on the two sections.
Finally, to effectively complete any dV-DOSC installation, either stacked or flown, the operator has
to carefully verify by actual measurement that the parameters in ARRAY 2000 (Cutview) have been
implemented correctly. Tools and procedures that are useful for this purpose are described in
Chapter 5. Detailed flying and verification procedures are described in Chapter 4.
