JBL Pro Releases Vertec Calculator

JBL Professional announced the release of its new Line Array Calculator II software, a stand-alone application with a range of enhancements for users of JBL's various line array system models.

The Line Array Calculator (LAC) II duplicates previous LAC functionality with a similar look and feel, but is now enables system designers and setup technicians to simulate mixed-model Vertec arrays; including the entire range of system options, from the full-sized VT4889 line array element and companion VT4880 arrayable subwoofer, to the midsized and compact models as well as JBL's latest VT4886 and VT4883 subcompact models.

According to the company, acoustical modeling with colorized graphical representation of results includes SPL mapping, 0 dB Isobar, and SPL attenuation modes. Frequency response and SPL based on the tonal balance of JBL's V4 DSP presets can be selected or maximum SPL compatible with EASE modeling predictions can be examined. Up to four frequencies can be simultaneously displayed, while up to six frequency response probes can be entered on up to four defined audience planes. Subwoofer modeling is also offered.

The company says that enhancements have also been made to the mechanical calculations for Vertec arrays with updated references for suspension hardware applications. User guidelines are now in place for up to 24 enclosures per array.

JBL's Line Array Calculator II v1.0 will soon be available for download at jblpro.com/vtcalculator.
