Downloading and Installing MAPP Online Pro
To use MAPP Online Pro, you can register at the following 
link:
After entering your registration information, an email will be 
sent to you with your user name, password, and the MAPP 
Online Pro download location. On-screen instructions will 
guide you through the download and installation process.
The MAPP Online Pro client software is regularly upgraded 
to add support for the latest Meyer Sound loudspeakers, as 
well as to add feature enhancements. Most upgrades are 
downloaded automatically when logging on to a MAPP 
Online Pro session. The MAPP Online Pro database 
includes nearly all of the current Meyer Sound loudspeakers, 
subwoofers, and processors.
SIM 3 MEASUREMENT SYSTEM
The SIM 3 audio analyzer is a high-resolution audio mea-
surement system comprised of software, hardware, micro-
phones, and accessory cables. SIM 3 is optimized for 
measuring audio frequencies with resolutions up 1/48th of 
an octave, allowing you to apply precise corrections to bal-
ance system response using frequency and phase domain 
information.
Source Independent Measurement Technique
The SIM 3 audio analyzer implements Meyer Sound’s 
source independent measurement technique, a dual-chan-
nel method that accommodates statistically unpredictable 
excitation signals. Any excitation signal within a desired fre-
quency range can be used to obtain highly accurate mea-
surements for acoustical or electronic systems. For 
example, concert halls and loudspeaker systems can be 
captured during a performance and used as a SIM 3 test 
signal, so you can:
View measurement data as amplitude versus time 
(impulse response) or amplitude and phase versus fre-
quency (frequency response)
Utilize a single-channel spectrum mode
View frequency domain data with a logarithmic fre-
quency axis
Determine and internally compensate for propagation 
delays using the SIM 3 Delay Finder
SIM 3 Applications
SIM 3’s main applications are testing and aligning loud-
speaker systems, which entails:
Measuring propagation delays between subsystems to 
determine appropriate polarities and delay times
Measuring variations in frequency response caused by 
the acoustical environment and the placement and inter-
action of loudspeakers to determine corrective equaliza-
tion
Optimizing subwoofer integrations
Optimizing loudspeaker arrays
SIM 3 can also be used in the following applications:
Microphone calibration and equalization
Transducer evaluation and correction
Echo detection and analysis
Vibration analysis
Architectural acoustics
Underwater acoustics
