Array calculators
ArrayCalc
For both acoustical and safety reasons J- and Q-Series arrays should be designed using the
d&b ArrayCalc V4 simulation tool. It runs exclusively  on Microsoft
Excel for Windows  , Version 2000 or higher, or on Microsoft Excel for
Mac  , Version 2004. ArrayCalc supports d&b audiotechnik
loudspeakers from the J-Series and Q-Series; it is used for planning system configurations.
This includes defining the quantity and optimum aiming of loudspeakers, calculating subwoofer
arrays and the time alignment of these to the main arrays, 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 flown arrays including the mechanical
load conditions within a column, load safety information, load values for rigging points and
displays warnings should an overload occur. ArrayCalc uses a sophisticated mathematical model
synthesizing each loudspeaker's wave front with an array of narrowly spaced point sources.
Using complex data (phase information) level distribution is calculated in multiple frequency
bands for up to three main 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.
Q-Calc
d&b Q-Series Q1 arrays can either be designed using the d&b ArrayCalc calculator
described above or the d&b Q-Calc Array calculators. Both Q-Calc calculators run
exclusively on Microsoft Excel for Windows or Mac,
version 2000 or higher.
In order to cater for either stacked or flown arrays, two different versions of Q-Calc are available.
Q-CalcStack is used to aid the planning, dimensions and aiming of ground stacked Q1s and Q-SUBs.
Q-CalcRig is recommended for the acoustical and mechanical design of all flown Q1 arrays,
including the mechanical load conditions within a column, safety information and values for rigging
points. The electroacoustical component of both calculators determines the level distribution over
distance for up to three audience areas.
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.

d&b ArrayCalc and Q-Calc require support for the Microsoft Visual
Basic for Applications programming language. Any Microsoft Excel
compatible programs without this support, such as those for PDAs are not capable of running the
d&b Array calculators.
