Pat BrownPat 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 way through multi-media demonstrations. SynAudCon is recognized as an industry leader in audio education.

SynAudCon offers both in-person and online audio training. There are regularly scheduled in-person seminars and special one-time events on audio-related topics. With the release of the online 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 online audio training courses as his most complete book, being able to explain the concepts and principles with animations and demonstrations.

He was chosen as NSCA Educator of the Year in 2005 and NSCA Mover and Shaker Award in 2011. He received Great Britain s 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, China, Philippines, Thailand, Singapore, South America, Australia and Canada.

Pat and Brenda Brown founded a second business in 2005 Pro Sound Testing, Inc. Pro Sound Testing measures loudspeakers to produce data files for use in room acoustics modeling programs. Pro Sound Testing was the first company of its kind in the USA. The experience of developing a measurement facility 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.

Frequently Asked Questions


How long will it take me to compete this course?

I hate to use the words “it depends” but is really does. It depends on your level of experience. Experienced people may complete it in a few hours. Others may take weeks as they may rather learn in bite-size pieces.

Here is a brief layout of the course.

Transformer Distributed Loudspeaker Systems consists of 6 lessons. After each lesson, you may take a quiz. Each quiz has 15 questions. The questions required that you have a good understanding of the principles that are taught.

After completing the lessons and quizzes, you may take a final exam. The final exam is about 30 questions. With a passing score, you will receive a certificate of completion and CEU’s.

You will have 3 opportunities to pass the final exam. We consider 80% as the passing score.

What if I got into the first couple of lessons and realized that I should have taken a more basic course?

No worries. The upper levels courses assumed you that you understand the principles presented in the lower level courses. If you need a more basic course, contact Brenda within 2 days of your key activation and she will exchange it.

We would like to urge you to take the self-evaluation quizzes. Take them more than once as new questions will appear. The quizzes will help you make a more informed decision.

We are developing an educational path for our employees. How does SynAudCon fit into this?

You will love this feature. SynAudCon online training is part of a Learning Management System which allows for tracking. Education supervisors may check the employee’s progress, quiz and final exam scores.

Is there a time limit on watching the online training?

You will have 45 days to complete the course. The 45-day clock begins on the day that the course key is activated. If you need more time, no problem. Brenda will gladly extend it for you.

We want you to get the most out of this learning opportunity. We would rather extend it than for you to rush through the course.

If you need a quick review of the course after it has expired, contact Brenda. She will reactivate the training for 5 days.

What course materials can I keep after the course?

Text to the training videos.
Lesson Graphics Great which are great for note-taking.

These resources are comparable to a course manual if you were attending an in-person seminar.

Will I receive a certificate?

Of course. After passing the final exam, a certificate of completion will be emailed to you within one business day. The certificate will include the information that you will need for the Continuing Education Units.

How do I ask questions about the this training?

I gave SynAudCon online training as a gift.

Since my first SAC class at The Farm in 1992 with Don and Carolyn (and Pat s first appearance as a guest instructor!), I’ve followed up with several more SAC courses and workshops over the years, founded and built a company that is fortunate enough to be a contributor to the SAC community through sponsorship and have met the most brilliant people in our industry. I cherish the friendships and long relationships on a global scale. This listserv is something I look forward to reading every day and the education (and some great laughter) never ends.

So before the holidays with those gift giving ideas swirling around, the obvious occurred to me. I wanted to give my daughter and step son something enduring and special. I gave them the gift of SAC online courses. They were totally jazzed when they opened the cards with the news of a pair of courses for each of them. They dove into one of my mix desks and a DAW was set up on a dedicated PC in anticipation.

I’m convinced that learning the fundamentals of audio and sound system design will serve them well in their lives through observation if not a skill. I would be thrilled if they both join our ranks in the future, but only time will tell.

Far be this note a commercial but rather my finding a particular joy in audio gift giving and wanting to share it with you because I’m convinced that we all got here through quality mentoring and sheer passion. Perhaps a SAC course is a way you can pay it forward.
