12VTX B 18 | Rigging Manual5 - SOFTWARE5.1 - LINE ARRAY CALCULATOR 3 TMLAC is a simulation software for designing and predicting JBL VTX Series systems. LAC predicts the acoustical performance coverage ofline array systems as well as flown and ground stacked subwoofer arrays. Enhanced acoustical modeling includes color SPL mapping, 0dB isobar and SPL attenuation modes with the frequency response and SPL based on JBL’s DSP presets. Up to 8 virtual microphonescan be placed in the venue for accurate, position-dependent response prediction. Additionally, subwoofer modeling is now offered.Subwoofer delay values can be generated for electronic delay steering (EDS) of subwoofer arrays using the built-in calculator.Beyond the acoustical prediction, LAC is used for mechanical validation of all used suspension hardware. Weight limits are calculatedin real time for single or dual-point suspensions. An array design factor is calculated that can be used for designing an array within localregulation limits. Safety warning massages are displayed when an unsafe configuration has been selected. Array statistics like arraysize, depth and weight are also calculated. |
