Although detailed blueprints are not necessarily required, the more information that can be obtained
on a venue for defining the audience geometry the better. Typically, plan and section views are
available for most venues upon request. In situations where such documentation does not exist,
there are a number of options: use a tape measure or laser range-finder on site to perform
dimensional measurements. Alternatively, L-ACOUSTICS has had good results with the Bushnell
Yardage Pro 600 for field measurements. Apart from being useful for defining room geometry, this
tool can also be used for determining delay time settings during system tuning, for locating laser
beams during array trim and angle adjustment (and even on the golf course on days off!). In some
cases, tribune or balcony elevations can be determined by measuring individual step depth/height and
then counting the number of steps to calculate the section depth/elevation.
The ROOM DIM sheet is provided in ARRAY 2000 to assist in calculating cutview data from room
measurements (see Figure 23 for details).
Note: the calculation of elevation Z2 is susceptible to small errors in distance measurements and should
always be verified with a tape measure whenever possible. Combined distance/angle measurements are
typically more accurate than distance only measurements when calculating Z2.

In dV-DOSC ARRAY#1 or ARRAY#2 cells, the designer enters the number of dV-DOSC elements,
the elevation of the bumper and the autofocus adjust angle. Normally, ARRAY 2000 automatically
focuses the top element to the rear of the audience geometry that is defined in Cutview 1.
Autofocus adjust can be used to adjust the overall focus of the array and DOES NOT
CORRESPOND TO THE OFFSET ANGLE OF THE BUMPER.
The designer then chooses the angular spacing between elements from the available values (0°, 2°,
3.75°, 5.5°, 7.5° for dV-ANGLEP1 or 1°, 3°, 4.5°, 6.5° for dV-ANGLEP2). The red lines (beam
display) show the aiming directions of all elements, where each line is aligned perpendicular to the
middle of its respective enclosure. Note that the displayed top element corresponds to the
BUMPER, not the first element of the dV-DOSC array. XZ cells can be used to enter additional
room features such as balcony profiles, stage/proscenium details, FOH mix position, etc.
