Directional amplification, also referred to as Source-Oriented Reinforcement (SOR), describes a practical technique to deliver amplified sound to a large listening area with even coverage while providing directional information to reinforce visual cues and create a realistic and non-contradictory auditory panorama. Audio demonstrations of the fundamental psychoacoustic techniques employed in a SOR design will be presented and limits discussed.

The panel of presenters will outline the history of SOR from the pioneering work of Ahnert, Steinke, and Fels with their Delta Stereophony System in the mid 1970s (later licensed to AKG), to Out Board’s current day TiMax Audio Imaging Delay Matrix, including the very latest ground breaking technology employed to enable control of precedence by radar tracking the actors on the stage.
Descriptions of venues and productions that have employed SOR will be included.
