INTRODUCTION TO THIS MANUAL
This manual is the primary user guide for setting up and using the SIM 3 audio analyzer to
perform audio measurements for aligning and optimizing sound systems. It describes all of
the features and functionality of the hardware and software, and provides basic guidance in
how to use SIM 3 to perform measurements. In addition to this manual, Meyer Sound offers
comprehensive training sessions on how to most effectively and successfully use the SIM 3
measurement technology; go to www.meyersound.com to find training schedules and other
information.
Meyer Sound makes an ongoing effort to assure that SIM 3 is the most accurate and
potent tool for performing audio measurements, while making the user interface relatively
simple to use and understand. However, SIM 3 is a very powerful and deep measurement
methodology, and a combination of some experience in audio testing and time spent using
the analyzer will be required to use SIM 3 to its full extent.
Chapter 1: SIM 3 Measurement Terminology is a reference that gives definitions of the
measurement terms and concepts that are used in SIM 3, including source independent
measurement, transfer functions, and coherence.
Chapter 2: The SIM 3 Hardware details the SIM-3022 audio analyzer, switchers, and
other system components; it also provides descriptions and illustrations of various system
configurations.
Chapter 3: SIM 3 Branches provides a thorough overview of the concept of Branches,
which are the basis of all SIM 3 measurements. The chapter includes understanding and
using the Branch setup windows, configuring and naming branches, working with line and
mic switchers, and how branches are used in measurements.
Chapter 4: Software Updating discusses the procedures to update the software in the SIM-
3022 audio analyzer, and how to install and use the Setup & DataViewer software for PC to
work with SIM 3 data offline.
Chapter 5: The Measurements — Definitions and Applications provides an in-depth
discussion of the Band Spectrum, Line Spectrum, Delay Finder, and Frequency Response
measurements, including their functions and applications when using SIM 3 to align a sound
system.
Chapter 6: The SIM 3 Measurement Screen details all of the controls and functions that
are available on the SIM 3 screen for each measurement. This chapter includes tips on
how to most effectively and efficiently use the tools to move between measurements, plus
alternative ways and shortcuts for performing common tasks in SIM.
Chapter 7: Using SIM 3 puts it all together, outlining how to use the analyzer to perform,
