VMB Rainbow electro-acoustical prediction software for the company’s speaker systems features horizontal as well as vertical modeling. The Windows-based software allows simulation of complete systems, such as a main large format array complemented by a smaller delayed array and front-fills.
Its library of loudspeaker systems includes, the company’s self-powered line array modules with built-in inclinometer (LX-V8 and LX-F6 with accordion-folded ribbon HF driver) and models from its PHASE or ADP lines.
“Customers need to model a complete system,” noted Jesús Fuentes, national sales director. “Generic software is okay if only a single array is used. In practice, however, fill systems are usually required. One must also examine what’s happening in the horizontal plane, not just vertically. So the only way to provide a complete solution was to develop our own software.”
High resolution (24 point per octave) speaker polar data with magnitude and phase information allow accurate modeling down to 30 Hz, enabling user-designed subwoofer arrays. Rear radiation levels are critical for cardioid system design, so subwoofer cabinets use real measurements across all frequencies.
“Venue-specific subwoofer array design is key to achieving uniform bass coverage,” said Joel Damiano, applications manager. “System engineers will appreciate being able to predict cardioid, end-fired and other arrangements, such as physically or electronically steered or arced bass arrays.”
Rainbow can also import external WMF format drawing files, allowing architectural details or rigging structures, to be added to any project. Additionally, coverage maps can be exported, and a global report can be printed with comprehensive information (dimensions, angles, weight, center of gravity, etc.). Other functions include quick readout of SPL, distance to the loudspeakers and distance, angle or delay time between two points.
