Sound Reinforcement For Technicians

iPod Touch Workstations

iPod Touch Workstations

It’s relatively easy to interconnect a chain of audio components to produce sound. But what if it doesn’t sound right?

    • How do I remove that hum or buzz?
    • What are the proper settings for the DSP?
    • Is the gain structure correct?
    • What is the best way to equalize and optimize a system.

Our “Sound Reinforcement for Technicians” 3-day seminar with “hands-on” exercises will answer these questions and more. Each attendee will use an iPod Touch controlling an audio instrumentation interface. Via our signal distribution system, each attendee will be able to measure voltage, impedance, polarity, SPL and STIPA with the instrument. More importantly, they will learn what these measurements mean, and how to use them to ensure that the system is performing optimally.

How many ?


We take a multimedia presentation and an interactive “hands on” approach with this 3-day seminar.

The class is approved for 24 InfoComm Renewal Units, 10 CEDIA CEUs, and 21 BICSI CECs. Continuing Education Overview

Who Should Attend?

Each workstation includes an iPod Touch controlling an audio instrumentation interface.

This seminar is for those who install, configure and calibrate sound reinforcement systems.

Suggested Prerequisite:

Principles of Audio - Web-Based

Supplies Needed:

A notebook computer is optional. Pat will be using our "Audio Click-Rule" software program for demonstrations/calculations. It is included in the course materials, and you may follow along if you wish.

Seminar Description

Learning "how it works" is the key to troubleshooting and setting the system up correctly.

This seminar has been updated and refined for 2013. It covers the theory behind how systems work, and demonstrates how to use instrumentation to look "under the hood" to troubleshoot systems.

SR for Technicians includes "Hands-On" Exercises. Each workstation includes an iPod Touch controlling an audio instrumentation interface. Via our signal distribution system, each attendee will be able to measure voltage, impedance, polarity, SPL, spectrum analysis and speech intelligibility with the instrument.

The class also demonstrates the universal principles of how to use modern dual-channel FFT measurement platforms. On day three, we show the setup of an active, multi-way loudspeaker, including polarity testing, equalization, crossover selection and signal alignment.

The principles presented in the Technicians seminar are built upon those presented in the "Principles of Audio" Web-based Course.

What You Will Learn

  • The inner workings of audio interfaces, including a practical exposure to concepts of voltage, current, impedance, power and other signal characteristics.
  • How to select loudspeaker cables based on loudspeaker impedance and required cable length.
  • How to establish an optimum system gain structure using both "on the fly" and in-depth approaches.
  • How to know how much power you are feeding a loudspeaker, and how to stay below the loudspeaker's power limits.
  • The proper use of peak and RMS metering to track audio signals.
  • How to figure out if you should run your power amplifier in dual-channel or bridge-mono mode.
  • The principles of grounding and shielding for quiet and safe interfaces.
  • The essential and common principles of all pc-based measurement systems, enabling you to use any of them to their fullest potential.
  • An equalization strategy that gets at what you can fix, and avoids "over equalizing" the sound system.
  • How to calibrate a loudspeaker signal processing chain, including crossover, equalizer, delay and compressor/limiter.
  • How 70 volt systems work, and how to make sure they are properly interfaced and adjusted.


Pat Brown is a 1978 graduate of the University of Louisville with a degree in electrical engineering technology. With a background as a musician, sound technician, retail music store owner, contractor, and consultant, he is familiar with the many aspects of audio. He served as an associate instructor to audio legend and SynAudCon founder, Don Davis. Pat along with his wife Brenda own and operate SynAudCon and have been providing training for the audio industry since 1996. Pat, the main instructor for SynAudCon, has the unique gift of being able to share his knowledge of complex technical topics in an easy-to-understand real world manner through multi-media demonstrations. SynAudCon is recognized as a industry leader in audio education.

SynAudCon offers both in-person and web-based audio training. There are regularly scheduled in-person training and special one-time events as instruction on new technology is needed. With the release of the web-based training in 2010, SynAudCon training is now more accessible worldwide.

Pat writes articles for several publications. He authored three chapters for Glen Ballou’s “Handbook for Sound Engineers” and is co-author of Sound System Engineering 4th Edition. He considers SynAudCon web-based audio training courses as his most complete “book,” being able to explain the concepts and principles with animations and demonstrations.

Pat regularly teaches for the industry trade organizations - NSCA, InfoComm, and LDI. He was chosen as NSCA “Educator of the Year” in 2005 and NSCA “Mover and Shaker” Award in 2011 & “Peter Barnett” Award in 2012.

SynAudCon has given private seminars to many companies and organizations, including the Kennedy Space Center, Disney World, Sea World, IMAX, Purdue University, the US military, Siemens and many audio manufacturers. He has conducted seminars in Europe, the Middle East, Africa, Asia, South America, Australia and Canada.

Pat and Brenda Brown founded a second business in 2005 - Electro-acoustic Testing Company (ETC). ETC, Inc. measures loudspeakers to produce data files for use in room acoustics modeling programs. ETC, Inc. was the first company of its kind in the USA. This experience of developing a measurement facilty and measuring hundreds of loudspeakers from dozens of manufacturers has allowed him to develop some methodologies and specifications that have influenced a number of industry standards.
