Frequently Asked Questions

FAQ

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.

Thanks Brenda was a good course.  J.H.

Great information at a great value!  G.V.

The click-rule calculator is an amazing tool! I did not realized it existed until this course.  J.G.

It’s good information.  J.C.

I appreciate the online options to earn renewal credits. I prefer to support you rather than take alternative training. I always learn (or remember) something useful. T.F. (12X SynAudCon Grad)

I liked how comparisons to more familiar objects and scenarios we made. It help out a lot understanding some of the concepts.  C.M.

“I like it. Don’t change a thing.  B.W.

Thank you very much! We are finding this training invaluable to being efficient in the field. My other colleagues in Service will also likely be taking them. F.T.

This was my favorite course this far. I struggled on the test with turns ratio and figuring out the ratio but other than that thought everything was explained very well.  T.F.

It was a great course. I failed the final exam but I still think the course was beneficial and worth the price. I just had a hard time wrapping my head around conversions between voltage watts and ohms. B.S.

You guys are awesome for having created this course and making these things accessible for so many. This has already helped me in many situations at work.  J.S.

Good info. Glad to see it broken into a separate course as it is very relevant to the Enterprise/Corporate AV World.  A.F.

These should be perquisite for CTS training.  D.K.

Very easy to follow and understand. I enjoyed being able to re watch lessons until I understood.  T.F.

Helpful. I learned more about the speaker and amplifier installation. B. D.

I’m Happy with the course 🙂 E.C.

It’s wonderfully clear. The pace is slow enough that I can really think about every word that’s spoken. F. M

Very well put together. F. T.

I’ve enjoyed all my SynAudCon courses so far. I look forward to completing more. R.B.

It was an overall great course! Loved the videos and written dialogue to follow along with. H. B.

This was challenging and very well presented. I appreciate Pat’s knowledge and wisdom on this subject. It definitely connected the dots for me, and will help me tremendously in the lab at AtlasIED in Ennis. Thank you also for SAC Click Rule! Well done.  Thank you, again,  for an outstanding course! J.P.

I just enjoy your classes. D. C.

This was a great course.  D.H.

I really enjoyed the course. I’ve been using the PDF documents to supplement the videos which has been a big help. One suggestion I have would be to include some of the graphics used in the video with the text.  N.B. 

I rate the training as a 5, with 5 being the highest score.  I have one suggestion, I used a iPad for this course, but couldn’t use the audio click rule on my iPad. It would be great if it were available. D.T.

I liked the ability to go over sections multiple times to figure out the concepts and the math – which I am getting better.  The Click Rule is a great tool! G.W.

The formulas went by really fast. I got the theories, fine (which seem to be drilled more), but could have used more time and examples, to learn how to know which formula to use for each situation. J.E.

I enjoy what you guys are doing.
I really enjoy the use of comedy throughout the courses. S.A.

Very interactive, easy instructions, well thought-out modules. A. P.

I was very pleased with the course over all. I have been working with transformer distributed systems for quite some time and still learned new things or clarification of things I was taught to do but didn’t really understand why. R.T.

Our audio guys are learning a ton.

Just a note to say thanks and that our audio guys are learning a ton and loving your courses. Thanks for the blogs and communication. Keep up the great work.

Mark Richards, The Way International

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.

Your training helped me organized my knowledge.

Your training helped me organized my knowledge. It also clarified some doubts that have puzzled me.

Thanks very much! It is very helpful for my job in AVW-TELAV.
