Electro-Voice announces release of LAPS V2.2A
Electro-Voice is pleased to announce the release of LAPS V2.2A; this new version of LAPS, the Electro-Voice line array modeling and design program, is available for free download from the EV website at:
LAPS is an essential tool for sound system designers who use EV line array loudspeakers. Using LAPS, a designer can quickly enter an array design and assess its performance. LAPS can model a full sound system, including main arrays, secondary arrays such as delays and front-fills, and subwoofers. 
After the final system design is chosen, LAPS provides full rigging specifications. LAPS includes comprehensive checking of rigging working loads, and will not predict performance of rigs which it considers to be unsafe.
The new version includes a special page for predicting coverage of subwoofer arrays. Proper use of this page will in many cases result in significant bass coverage and quality improvement at little or no additional cost.
LAPS supports all EV line array products and related subwoofer models.
The new version is designated LAPS 2.2A. It includes the following specific changes:
The following new workbook pages have been added:
·         Arrays Bass page, for predicting horizontal coverage of subwoofer arrays.
·         Air Loss page, for predicting sound attenuation in air over large distances.
·         Cable Loss page, for modeling the resistive and capacitive effects of loudspeaker cable.
·         Supported Products page, which lists all products supported by LAPS 2.2A.
Support has been added for the following new EV products:
XLC Family
·         XLC-907DVX Full-range loudspeaker, 90° horizontal coverage.
·         CBEAM (new beam) in reversed orientation.
·         XLCbeamF (old XLC tilt angle extender) extending to the front.
·         XLCbeamR (old XLC tilt angle extender) extending to the rear.
·         dB Sound XLC grid and extender bar.
XLVC Family
·         XLD-291 Full-range loudspeaker, 90° horizontal coverage.
·         XLE-291 Full-range loudspeaker, 90° horizontal coverage.
·         XCS312 3x12” cardioid subwoofer.
·         CBEAM (new beam) in reversed orientation.
·         AGSE XS-212 to XLE adapter grid.
X-Line Family
·         XVLSred Full-range loudspeaker, 90° horizontal coverage, high rig load version.
·         dB Sound X-line grid and extender bar.
EVA Family
·         EVA loudspeaker line (four models and three grids).
Array modeling capabilities have been improved.
·         Maximum main-to-delay distance is increased to 412 ft (125m).
·         Coverage prediction curves are now more accurate above 6000 Hz.
·         Array equalization predictions now include realistic target frequency response curves.
·         The polar response display is now more usable for large array tilt angles.
·         In the array specifications, it is now possible insert boxes without re-entering existing ones.
·         General appearance has been upgraded.
·         Venue and array printouts now deal correctly with hidden data.
·         There is now a popup in-progress message boxes for saving files and generating reports.
·         Optional dropdown lists have been implemented for entry of box drive level.
Rig Report
·         Rig report formatting and pagination has been improved.
·         Trim height and rig bottom height now appear on rig report.
·         Rig report display of diagnostic messages is improved.
Other Enhancements and Fixes
·         Pullback points for X-Line arrays are now handled better.
·         For uptilted X-Line arrays, LAPS now warns if front chain links will collapse.
·         The rig top reference point has been changed to top front corner of topmost element.
·         Changed internal relationships to allow multiple versions of LAPS II to coexist on same machine more easily.
·         Windows Vista is officially supported.
·         Updated and enhanced help information generally.
·         Made LAPS able to load .EVA files written by EV's EVADA modeling program.
·         Improved Load/Save handling of international date formats. Previously, LAPS sometimes failed to load .laps files from foreign countries.
LAPS is a Microsoft Excel-based application that runs in Windows environments. It requires Excel 2000 or later and Microsoft Windows 2000 or later.
