LAPS 3
VERSION 3.0.1 - RELEASE NOTES
This document describes release 3.0.1 of Electro-Voice’s Line Array Prediction System (LAPS 3). LAPS
3 is a Microsoft Excel® application with a MATLAB-based calculation engine that assists in configuring
and operating Electro-Voice line array loudspeaker products.
Installation instructions for LAPS 3.0.1 are in Appendix A, below. A summary of new features in LAPS
3.0.1 is in Appendix B, below.
1. Overview
1.1.
Applicability
LAPS 3.0.1 may be used to predict array behavior of the Electro-Voice X-Line Advance line array
products.
1.2.
Capabilities
Based on user input, LAPS 3.0.1 predicts the following parameters:
•
SPL in audience areas.
•
Polar response.
•
Equalization required to achieve flat frequency response at the front of house mix position or any
other chosen position in the venue.
•
Mechanical rigging configuration, suspension, and safe practice requirements.
Predictions may be done for venues with a main floor plus up to two balconies.
Acoustic predictions are performed simultaneously for up to three frequency bands. Frequencies and
bandwidths are supplied by default, but may be freely changed by the user.
1.3.
Auxiliary Pages
LAPS 3.0.1 includes two auxiliary pages for calculating:
•
Sound loss due to air propagation over long distances.
Note that LAPS 3.0.1, unlike previous versions of LAPS, includes air loss in its basic predictions.
Therefore, you will probably not normally need to use this page.
•
Loudspeaker electrical signal losses due to resistance of loudspeaker cable.
2. User Interface
LAPS 3.0.1 accepts input and displays results on a formatted multipage Excel® worksheet. All worksheet
pages are printer-friendly.
Both English and Metric units of measure are supported.
Unlike other spreadsheet-based array prediction programs, LAPS 3.0.1 saves and restores its array and
venue specification data in compact text files, not in full spreadsheet files. This results in a significant
reduction in file space requirements.

LAPS 3.0.1 • VERSION 3.0.1 - RELEASE NOTES
REV. 7 / MAY 6, 2015
Appendix A. Installing LAPS 3.0.1
Note: At present, LAPS 3.0.1 is released only for 32-bit versions of Microsoft Excel. Future releases will
support both 32-bit and 64-bit versions of Excel. Please note that the choice of 32 or 64 bit MCR
depends only on the version of Excel you are running, not on the wordsize (i.e. number of bits) of your
computer's hardware.
Step 1: Install the MATLAB Compiler Runtimes (MCR) library
The LAPS 3.0.1 acoustical calculation engine is built on the MATLAB numerical computing system. To
run, LAPS 3.0.1 requires installation of the (free) MATLAB Compiler Runtimes (MCR) library. This
library, while rather large - approximately 650 MB - need be installed only once, and not every time LAPS
is updated.
Please install the free MCR library by visiting the following web page:
http://www.mathworks.com/products/compiler/mcr/
This page offers a number of installation options. For LAPS 3, the correct choice is:
R2014b(8.4), Windows, 32-bit
Figure 1 shows the version table that appears on the MCR webpage, and indicates the version to be used
with LAPS.
Figure 1. MATLAB MCR Downloads
The MCR library installer is an .exe file which you may run to install the MCR library. Once the library is
installed, you may delete the MCR installer file.
Step 2: Install LAPS 3.0.1
LAPS 3.0.1 is distributed in the form of an executable installer named
LAPS 3.0.1 beta Installer32.exe .
This file is downloadable from the Electro-Voice website. Size is approximately 50 MB.

LAPS 3.0.1 • VERSION 3.0.1 - RELEASE NOTES
REV. 7 / MAY 6, 2015
Appendix B. What's New in LAPS 3.0.1
LAPS 3.0.1 is the first release of the LAPS 3 prediction software family from EV. While superficially
similar to its predecessor LAPS II, LAPS 3 software is based on a completely new acoustic and
mechanical computation engine called the Optimizer. The Optimizer provides a number of benefits in
LAPS 3.0.1, and will allow the addition of significant new functions in the future.
New features in LAPS 3.0.1 are:
Acoustics
•
More accurate and detailed acoustical predictions. The Optimizer's predictions are based on
full high-resolution measured loudspeaker data. The use of this data provides much more
precise prediction results, especially in the high frequencies.
•
Full accounting for air absorption. The Optimizer takes air absorption fully into account, to
provide much more accurate prediction of far-field array performance in large venues.
Mechanics
•
Support for mechanically advanced rigging architectures. The new X-Line Advance line
array loudspeaker family has a mechanically advanced rigging system that provides smoothly
curved arrays at all angles. LAPS 3.0.1 fully supports this.
•
Support for pullback-to-grid arrays. The X-Line Advance family supports a new rigging mode
in which a tension cable attached to the rear of the grid is used to pull the array into the desired
arc. LAPS 3.0.1 fully supports this.
•
Improved diagnostic messages. LAPS 3.0.1 rigging diagnostic messages have been made
clearer and more informative.
•
Selectable rigging safety factor. The LAPS 3.0.1 Preferences page now allows the rigging load
safety factor to be set to 8:1, 10:1, or 12:1, to accommodate differences in local regulations. The
chosen safety factor is used in all array load-limit checks.
•
Improved RigReport. The RigReport has been upgraded to be clearer and more compact, and
to support the new features noted above.
•
Improved RigPic. The RigPic has been upgraded to show the new features. As well, it now
provides clearer indication of "unriggable" configurations, i.e. configurations that fail load-limit
tests or otherwise should note be used.
General
•
Better product upgrade support. LAPS 3.0.1 and its successors allow separate distributions of
software and product data. In the future, users will be able to download and install LAPS data for
new products without having to install new versions of the LAPS 3 software.
COMING SOON
•
Support for delay clusters. LAPS 3.0.1 does not currently support delay clusters. An upcoming
update will add this feature.
•
Subwoofer prediction ('Arrays Bass' tab). LAPS 3.0.1 is being released without the 'Arrays
Bass' tab familiar to LAPS II users. This feature will be back soon!
•
Support for other EV line array product families. LAPS 3.0.1 currently supports only the XLine Advance product family. In the coming months, support will be added for the older line array
families - X-Line, Xlc, Xld, and Xle.

Appendix D.
Electro-Voice End-User License Agreement for
Electro-Voice LAPS Software
Electro-Voice LAPS software is a simplified guide that allows user to quickly approximate the acoustical
and mechanical attributes of "typical" loudspeaker arrays using Electro-Voice X-Line Advance
loudspeaker systems. As such, the software may not be feasible to model the loudspeaker array for your
specific application.
The LAPS software is designed specifically for use with Electro-Voice X-Line Advance loudspeaker
systems and is not applicable to other loudspeakers manufactured by Electro-Voice or to loudspeakers
from any other manufacturer.
The overall safety of a loudspeaker rigging installation depends on many factors, including the array
weight, the array configuration, the condition of the loudspeaker systems and loudspeaker rigging, the
associated external support hardware items necessary to rig a complete loudspeaker array (grids, chain
hoists, building or tower supports, the techniques used for the external support hardware and the
condition of the external support hardware. The LAPS software cannot take into account all the variables
necessary to predict a safe loudspeaker rigging installation.
Because the LAPS software presents an approximate mechanical model of loudspeaker arrays, it is not a
substitute for the structural ratings in the Users/Rigging Manuals included with the Electro-Voice
loudspeaker systems. It is the responsibility of the user to make sure that all Electro-Voice loudspeakers
suspended overhead meet the structural and safety requirements detailed in the Users/Rigging Manuals
and that the recommended Working Load Limits are not exceeded. The requirements governing rigging
hardware and practices may be superseded by local regulations. It is the responsibility of the user to
ensure that any Electro-Voice loudspeaker system is suspended overhead in accordance with all current
federal, state and local regulations.
Do not use this software or the manuals except in consultation with trained and experienced rigging
professionals with knowledge of hoisting and rigging practices and requirements, and who will exercise
independent judgment in assessing the safety of an intended installation.
All non-Electro-Voice associated hardware items necessary to rig a complete EV loudspeaker array
(grids, chain hoists, building or tower supports and miscellaneous mechanical components) are the
responsibility of others.
The Users/Rigging Manuals for the Electro-Voice loudspeakers may be obtained online at
www.electrovoice.com, or from Electro-Voice Technical Support, available by telephoning +1 800 392
3497, then selecting options 4, then 3, then 3, then 3.
