Harman’s JBL VerTec Line Array Calculator II Software, V 1.1 can be used to simulate mixed-model arrays from the entire range of VerTec enclosures. V 1.1 of the Line Array Calculator II (LAC II) V 1.1 retains much of the same appearance and functionality of the V 1.0 version, while offering a variety of new features.
For example, with LAC II V 1.1, new VerTec subcompact line array accessories (VT4886-SF, VT4886-DF88, VT4886-DF89) are included, and parametric EQ (compatible with JBL DrivePack, Crown Audio I-Tech/I-Tech HD and dbx 4800) is introduced. Signal delay functions are linked for all VT4889, VT4888, VT4887A, VT4887 and VT4886 enclosures, including DrivePack models, while subwoofer model delays remain individually selectable. LAC II V 1.1 also features an SPL Mapping View probe (displaying XY coordinates and SPL).
With LAC II V 1.1, it is now possible to manually create circuit groups so that EQ, Delay and Gain are linked. LAC II V 1.1 also offers a user-selectable Auto-Update, and a check for updates can be launched from the Help menu. Additional VerTec V4 preset data is now included in the Frequency Range menu.
As with the previous LAC II software, V 1.1 features enhanced acoustical modeling with colorized graphical representation of results, including SPL mapping, 0 dB Isobar, and SPL attenuation modes. User guidelines allow for up to 24 enclosures per array.
