CHAPTER 7: SYSTEM DESIGN AND INTEGRATION TOOLS
Meyer Sound offers two comprehensive tools to assist with 
the acoustical and functional requirements of system design 
and optimization. This chapter introduces you to MAPP 
Online Pro, Meyer Sound’s patented online acoustical pre-
diction tool, and SIM 3, a comprehensive system for mea-
surement and analysis.
MAPP ONLINE PRO
MAPP Online Pro is a powerful, cross-platform, Java-based 
application for accurately predicting the coverage pattern, 
frequency response, impulse response, and maximum SPL 
output of single or arrayed Meyer Sound loudspeakers.
Residing on your local computer, the MAPP Online Pro client 
lets you configure Meyer Sound loudspeaker systems and 
define the environment in which they will operate, including 
air temperature, pressure, humidity, and even the location 
and composition of walls. CAD (DXF) files containing 
detailed venue information can also be imported.
Whether planning for fixed installations or tours with multiple 
venues, sound system designers can use MAPP Online Pro 
to accurately predict the appropriate loudspeaker deploy-
ment for each job, complete with coverage data, system 
delay and equalization settings, rigging information, and 
detailed design illustrations. MAPP Online Pro’s accurate, 
high-resolution predictions ensure that systems will perform 
as expected, thereby eliminating unexpected coverage 
problems and minimizing on-site adjustments.
The key to the accuracy of MAPP Online Pro’s predictions is 
its exhaustive database of Meyer Sound loudspeaker mea-
surements. Performance predictions for each loudspeaker 
are based on 360 1/48th-octave-band measurements taken 
with a SIM audio analyzer in the Meyer Sound anechoic 
chamber. The extraordinary consistency between Meyer 
Sound loudspeakers guarantees that predictions from 
MAPP Online Pro will closely match their actual perfor-
mance.
MAPP Online Pro predictions are requested by the client 
software and sent via the Internet to the high-speed Meyer 
Sound servers where high-resolution (magnitude and phase) 
polar data is processed with sophisticated acoustical pre-
diction algorithms. The resulting predictions are then 
returned to and displayed on the local computer running the 
MAPP Online Pro client software.
TIP: Meyer Sound offers seminars and webinars 
on using MAPP Online Pro. For more informa-

MAPP Online Pro Applications
With MAPP Online Pro, you can:
■Simulate different loudspeaker configurations to refine 
system design and zero-in on the best coverage for 
intended audience areas
■Monitor loudspeaker interactions to locate destructive 
interferences so that loudspeakers can be re-aimed and 
repositioned as necessary
■Place microphones anywhere in the sound field and pre-
dict their frequency response, impulse response, and 
sound pressure
■Determine delay settings for fill loudspeakers
■Try out virtual Galileo equalization to determine optimum 
real-world settings for the best system response
■Automatically calculate load information for arrays to 
determine rigging capacities, front-to-back weight distri-
bution, and center of gravity
■Generate and export system images for client presenta-
tions
