d&b Introduces ArrayCalc Simulation Software V7.6.11The d&b audiotechnik ArrayCalc simulation software is the planning tool for d&b systems; a comprehensive toolbox for all tasks associated with electroacoustic design, performance prediction, alignment, safety parameters, and rigging plots. In the decade since ArrayCalc was first established, many significant improvements have been introduced; hosting numerous new features, ArrayCalc V7.6 is no exception. Amongst these, improved room data input to define listening planes in three dimensions, the xC-Series column loudspeakers, as well as the D80 amplifier along with export functions into the new d&b R1 Remote control software V2; downloadable at www.dbaudio.com. Now called venue, the room input control enables the user to create a representation of the audience areas in a given venue in three dimensions. Since the world is round this includes typical listening planes, arenas, balconies, side stalls and 360-degree scenarios, even with curved edges. Additionally, the arena measurement function builds a virtual model using dimensions determined with a distance and angle finder, meaning individual planes no longer have to be predefined for arena models. The d&b ArrayCalc simulation software allows for precise initial simulations in the planning of systems, significantly reducing setup and tuning time in mobile and installed applications. Up to 14 flown arrays or subwoofer columns can be defined in a project file. d&b line and point source loudspeakers are selectable and can be included as the application requires. ArrayCalc simulates the direct sound performance of the system taking into account input level, all system configuration options (such as Arc, Line, CUT, CPL, HFC or INFRA), limiter activity, and air absorption. Acoustic shadowing caused by obstacles such as balcony overhangs or scoreboards can also be calculated. The load status of all rigging components is constantly monitored and displayed to determine whether a given array is within the SWL load tolerance. Ground-stacked sub arrays with as many as 51 positions can be modeled, the horizontal dispersion for different LF bands is then displayed. To achieve the desired directivity, ArrayCalc provides the individual delay settings for the subwoofers. Arrival times and sound pressure levels at a freely definable reference point on one of the audience listening areas is used to predetermine the time alignment and phase response between both flown and ground stacked sources. A comprehensive rigging plot with all necessary coordinates, dimensions, and weights of arrays with a parts list of all loudspeakers and rigging components is generated for export and printing. Finally, the R1 export function produces a project file for the R1 Remote control software. Complete details of the system simulated in ArrayCalc are generated, including loudspeakers, amplifiers, remote IDs, groups, and all configuration information. "We've finally got our heads around curved listening planes in this latest version," quipped Werner 'Vier' Bayer, "along with a sufficient number of sources and improved amplifier assignments within the R1 export function."
