OVERVIEW
JBL’s VERTEC™ Line Array Calculator II software duplicates previous LAC functionality with a similar look and feel, but now offers a more refined work tool that enables system designers and setup technicians to simulate a wide variety of VTX and VERTEC arrays. This includes the entire range of system options, from the fullsize VTX V25 line array element and companion VTX S28 arrayable subwoofer, through midsize and compact models, to the subcompact VERTEC VT4886 with companion VT4883 subwoofer. All VERTEC DrivePack models are also available for simulation, now including V5 tonal balance simulation for DP-DA models.
Enhanced acoustical modeling includes color SPL mapping, 0 dB Isobar, and SPL attenuation modes. Frequency response and SPL based on the tonal balance of JBL’s V5 DSP presets can be selected or, alternatively, maximum SPL for rated power at each frequency can be examined. Up to four frequencies can be simultaneously displayed, and up to six frequency response probes can be entered on up to four defined audience planes. Additionally, subwoofer modeling is now offered. Useful enhancements have also been made to the mechanical calculations for VERTEC arrays, with updated references for suspension hardware applications. User guidelines are in place for up to 24 enclosures per array.
Installing the Software – Operates on Windows operating system. Unzip the file into a directory and then run the “setup.exe” program. Your computer will need the latest version of Microsoft .NET 3.5 (the installer will prompt you to download it if your computer requires an update). If you already have a previous version of JBL’s Line Array Calculator II on your computer, the software should uninstall it automatically. If that doesn’t occur, then uninstall all previous versions using Add/Remove programs in the Windows Control Panel.
