Smaart Instructors

Meet some of the Smaart-est guys on the planet…..


Jamie has been teaching and working in the field of sound system engineering, measurement and alignment for over 25 year.  Prior to founding Rational Acoustics, he worked as a technical support manager and SIM instructor for Meyer Sound Laboratories, as a system engineer on tour for A-1 Audio (kd Lang) and UltraSound (Dave Matthews Band) as a product manager and instructor for SIA and EAW.

In the course of his professional career, Jamie has taught more than 350 SIM and Smaart classes, for over 5,000 students, in over 20 countries on 6 continents. He has been the house system engineer for 4 Montreux Jazz Festivals and 6 Telluride Bluegrass Festivals, has worked with Grateful Dead, Anita Baker and Louis Miguel Tours, and has been involved in hundreds of system alignments across a vast and diverse range of venues (studio to stadium) and applications (theatre, church, clubs, rock and roll tours, conventions, etc .)

What he has learned from his career so far is that art and practice of system alignment is as varied and expanding as the people, equipment and applications that encompass the field, that training classes are always a two-way street, and that anyone that understands their tools can create new and effective ways to use them.


After a brief internship followed by a part-time position, Chris officially joined Rational Acoustics as a full time employee in March 2012.
