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
