Sound System Engineering Clinic with Markus Zehner

 

 

 

 

 

 

 

Professional PA Planning, Setup and Calibration are the main topics of Markus Zehner’s current clinic series. A household name that pops up wherever there is a serious focus on sound system engineering, Markus’ wealth of knowledge and experience teaching seminars and workshops was the starting point for this four-day intensive course.
For Markus’ full range of clinics, seminars and other services, go to www.zehner.ch.
Days one to three of “Sound System Engineering” covered the principles of acoustics such as sound propagation, psychoacoustics, speaker and amplifier characteristics, filter phase and group delay, etc. Participants were given profound insight into the essential criteria for good or bad sound.
Day four was dedicated to the practical implementation of all this newly-acquired knowledge. At a rented event location, clinic participants were given the opportunity to build PA setups using data they had learnt to calculate over the first three days. Setups included a VERA10 line array, T24 point-source full-range speakers, B30 subwoofers and new BSX twin 21” subwoofers, all powered by Powersoft K3DSP system controllers. The morning was spent building various line array curvings, measuring and comparing them with a conventional T24 setup. In the afternoon participants calculated, built and tested multiple end-fire and cardidoid woofer constellations. These were validated using EASERA Systune measuring software. Knowledge duly improved and group photo in the bag, participants headed back to their workplaces, having been encouraged to use their new-found expertise in both live events and fixed installations.
We would like to thank Markus Zehner and all participants for the clinic’s positive, constructive atmosphere and for participants’ willingness to share and pool experience to everyone’s benefit. We’re definitely looking forward to our next clinic with Markus, so don’t miss it!
