For both acoustical and safety reasons d&b line arrays must be designed using the d&b ArrayCalc calculator, a simulation tool for planning line arrays and point source system configurations as well subwoofer arrays. This includes defining the quantity and optimum aiming of loudspeakers, calculating subwoofer arrays and the time alignment of these to a selected source, documenting weights and overall dimensions of arrays as well as producing printable rigging plots and parts lists. ArrayCalc calculates and displays the physical parameters of up to fourteen individual flown arrays including the mechanical load conditions within a column, load safety information and load values for rigging points, warnings are displayed should an overload occur. Simulation and integration of up to six groups of d&b point source loudspeakers are supported by an appropriate section.
ArrayCalc uses a sophisticated mathematical model synthesizing each loudspeaker's wave front with an array of narrowly spaced source points for line arrays and balloon data for point sources. Using complex data (phase information) level distribution is calculated in multiple frequency bands for up to five audience areas and optionally for side seating tiers.
ArrayCalc also calculates resulting dispersion of horizontally arrayed subwoofers at different LF bands and the delay values to achieve desired far-field coverage. The display of the phase responses of both Main and Sub Array at a selectable test point allows an applicable time alignment to be defined between flown and ground stacked parts of the system.
The d&b ArrayCalc calculator from Version 5 onwards offers programs for use either on Microsoft Windows, Version XP or higher, or Mac OS X, Version 10.4.10 or higher.

TransCalc and InstallCalc
d&b TransCalc and InstallCalc are Microsoft Excel based spreadsheets for planning Transformer and Installer flying system set ups. Loudspeaker array information can be entered and the spreadsheets then provide the flying system settings, weights for rigging points, cluster dimensions and rigging plots. Rigging plots and complete array part lists can be printed. Export functions are included to allow cluster information to be imported directly to CAD and electroacoustical simulation software.
TransCalc/InstallCalc now provides a graphic display for up to four listening planes in 2D projections showing the aiming points of all C3 and C4-TOP cabinets of the array.
