Convention Paper

DGRC Arrays : A Synthesis of Geometrical and Electronic Loudspeaker Arrays

Authors: Meynial, Xavier

AES Convention 120 · Paper 6786 · May 2006

Abstract

Loudspeaker arrays offer an efficient way of achieving both uniform SPL coverage and high sound clarity over a large audience area. Two types of arrays have been proposed over the last 15 years : geometrically steered J shape arrays, mainly for high power sound reinforcement ; and electronically steered vertical arrays, mainly for speech diffusion in public spaces. This paper introduces the “Digital and Geometric Radiation Control” (DGRC) principle, which combines the advantages of geometrical arrays and electronic arrays : array is vertical so that it can be mounted on a wall ; it is controlled with great flexibility using its DSP ; and the power is evenly distributed upon loudspeakers.
