It also details the height of your distance measuring device above plane 1. If the stage
is raised then include this height as well as the height of the device above the stage.
Note: It is assumed that plane 1 begins at the point where you mount the tripod and
the array will be flown directly above it.
To enter data for each plane aim your device at the beginning and end of the plane
and enter the values into the spaces provided. The units of measurement will be
determined by the choice made in the main window and negative aiming angles imply
the point aimed for is below the device.
Ensure that you have enabled or disabled the planes you require by checking the
enable tick box for each plane.
When you are satisfied with the data click Update venue, a conversion will then be
made to the direct form of venue dimension.
You can switch back and forth between the single point survey and direct form at any
time.
5.5.5 Coverage start and stop
Specify the horizontal coverage distances from the front of the array. Coverage start
and stop are shown as vertical grey bars on the view of the venue.
Please note:
A flown array’s overall curvature will be significantly increased by very close
coverage starts because the lower cabinets will need to aim further down. This will
decrease the number of straighter cabinets towards the top of the array decreasing the
efficiency of the far-field coverage.
See W8L Series Applications Guide Section 5.4 to relate maximum source spl to
loudspeaker quantity and curvature.
Always use a sensible choice of coverage start for the number of line array cabinets
available, using front-fill loudspeakers for the first 5 or 6 rows if at all possible.
Front-fills will also improve imaging. See Sect. 5.7.2
