Audio Precision, makers of Audio Test and Measurement equipment for over 25 years, is widely acclaimed for the superior performance of its products. The past five years have seen the release of the APx Series, an advanced line of Analyzer that pushes the limits even further with enhanced performance coupled with improved control and automation.

With the release of the APx555, the THD+N capability has been upgraded by 7 dB to -122dB. This month’s AES meeting will explore some of the modifications made, and the components required to achieve this level of performance.

Bob Snelgrove and Geoff Maurice of Gerr Audio, which has represented AP for over twenty years, will showcase the improvements in the APx series, and provide insight into the key role they played in its development. 

Join us for a comprehensive presentation and discussion of new measurement techniques in Analog and Digital Audio.


Bob Snelgrove is a veteran of the Canadian Professional Audio industry, founding GerrElectro Acoustic over 35 years ago and presently heading GerrAudio Distribution.  From designing Mixing Consoles and Automation systems, Snelgrove has seen it all.   Geoff Maurice, while a youngster in the professional audio industry, has grown over the last 7 years and heads up all Technical Sales at GerrAudio and everything Audio Precision.

While Sales oriented, GerrAudio’s roots always show through and the need to take apart every new cool piece of gear that comes through the doors still takes precedence over anything.
