Line Array Calculator (LAC) is a simulation software intended for the
design and prediction of JBL VTX Line Array systems and their acoustical
performance. In addition, you can also use the software with flown and
ground stacked JBL VTX Subwoofer Arrays. 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
LAC works with an intuitive drag and drop design and has SMAART integration within the software.
Line Array Calculator’s Enhanced Acoustical Modeling includes colour SPL
mapping, 0dB Isobar and SPL attenuation modes with frequency response
and SPL based on JBL’s VTX DSP presets. With it, you can place up to 8
virtual microphones in the venue for accurate position-dependent
response prediction. Additionally, the built-in Calculator is now
updated with subwoofer modeling, allowing you to generate subwoofer
delay values for electronic subwoofer array steering (EDS).
Mechanical Validation of single and dual-point array suspensions can now
include weight limit calculations in real time. 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. Safety warning messages can also be
provided when an unsafe configuration is selected.
Updates found in the new Line Array Calculator 3.2.0 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. Multiple subwoofer clusters can now be
entered into the display window and the software will predict broadband
polar response of the entire array. With Line Array Calculator 3.2.0,
system designers can now make more informed decisions about how
subwoofer arrays should be placed in venues and aid in the optimization
of these arrays for their best possible performance.

JBL ARRAYLINK INTEGRATION:
Array Link is a mobile companion app that works in conjunction with
JBL’s latest LAC-III software to assist technicians deploying JBL VTX
Series line array systems. Array Link uses a QR code system to transfer
all array mechanical information from the main LAC-III application to a
mobile phone – this transfer is done directly and in real time without
the need of internet connection. All relevant rigging information and
options are presented in an easy-to-understand layout.
The application is compatible with iOS® and Android and can be obtained from the respective App Stores.
