![]() Multiple subwoofer clusters can now be entered into the display window and the software will predict broadband polar response of the entire array. Updates found in the new Line Array Calculator 3 include: a completely redesigned UI that’s both more intuitive and combined with an unlimited number of planes more virtual measurement probes frequency response averaging of multiple virtual measurements and a brand-new subwoofer prediction mode. Safety warning messages can also be provided when an unsafe configuration is selected. Array statistics are calculated that include array size, depth and weight and array design factors are calculated, that you can use to design arrays that meet local safety and regulation limits. ![]() Mechanical Validation of single and dual-point array suspensions can now include weight limit calculations in real time. Additionally, the built-in Calculator is now updated with subwoofer modeling, allowing you to generate subwoofer delay values for electronic subwoofer array steering (EDS). With it, you can place up to 8 virtual microphones in the venue for accurate position-dependent response prediction. Line Array Calculator’s Enhanced Acoustical Modeling includes color SPL mapping, 0dB Isobar and SPL attenuation modes with frequency response and SPL based on JBL’s VTX DSP presets. Beyond just acoustical prediction, you can use Line Array Calculator for mechanical validation and the calculation of all weight limits and safety warnings for JBL VTX Systems. ![]() In addition, you can also use the software with flown and ground stacked JBL VTX Subwoofer Arrays. Line Array Calculator (LAC) is a simulation software intended for the design and prediction of JBL VTX Line Array systems and their acoustical performance.
