CHAPTER 6

Meyer Sound offers two comprehensive tools to assist you 
with the acoustical and functional requirements of system 
design and optimization. This chapter introduces you to 
MAPP Online Pro, Meyer Sound’s powerful online acoustical 
prediction tool, and SIM 3, a robust instrumentation package 
for system measurement, analysis, and more.

MEYER SOUND MAPP ONLINE PRO

Based on a patented method, 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. 

Figure 6.1. MAPP Online Pro is an intuitive, powerful system design tool

Residing on the user’s local computer, the Java client 
application facilitates configuring arrays of a wide variety 
of Meyer Sound products and, optionally, defining the 
environment in which they will operate, including air 
temperature, pressure, humidity, and the location and 
composition of walls. In addition CAD (DXF) files can be 
imported directly for accurate venue definition. You can find 
more information as well as apply for MAPP Online Pro at:

NOTE: 

To use MAPP Online Pro, you will 

need to register by clicking the “Apply for 

MAPP Online Pro” button on the Web page listed 
previously, or the “MAPP Online Pro” button on 
www.meyersound.com. After registration and upon 
approval, an email will be sent to you with a user 
name and password along with the URL where you 
can download MAPP Online Pro. Online instructions 
will guide you through the download and setup 
process.

When a prediction is requested, data are sent over the 
Internet to a high-powered server at Meyer Sound running 

a sophisticated acoustical prediction 
algorithm using high-resolution, 
complex (magnitude and phase) 
polar data. Predicted responses 
are returned over the Internet and 
displayed on the local computer in 
color.

With MAPP Online Pro, you can:

■

  Run multiple “what if” scenarios 

in minutes to refine your system 
design for best coverage of the 
intended audience area

■

  Clearly see interactions among 

loudspeakers to help minimize 
destructive interference by 
re-aiming the loudspeakers or 
adjusting the position

■

  Place microphones anywhere in 

the sound field and predict the 
frequency response, impulse 
response, and sound pressure at 
the microphone position

■

  Plan an entire portable or fixed loudspeaker system and 

determine delay settings for fill loudspeakers

■

  Use virtual Galileo equalization to predetermine the 

correct control settings for best system response

■

  Gain valuable load information about the array to 

determine rigging capacities, front to back weight 
distribution, as well as center of gravity of the array

■

  Export images to help generate explanatory 

presentation materials for clients
