Introduction

The acoustics of modern theatres and multipurpose halls are usually best suited for a single application: speech orientated shows like theatre, cabaret, lectures or movies. When programming classical musical performances like chamber music, opera and orchestral music, the acoustics of a hall need to be adapted to facilitate this. The improvements can be made by building measures such as increasing the volume of the hall, changing the wall panels and/or building an orchestral shell. Another, often faster and definitely more cost effective solution, is to install an acoustical enhancement system. Both the quality and the recognition of these systems have improved substantially over the last thirty years. Today, concert halls will often also be used for film projection and all sorts of creative performances, requiring sound effects like surround sound and source localization on stage. On top of that, the demands and expectations of spectators about sound quality have risen. People in the audience count on experiencing the same sound quality in each seat. The versatile XLNT Multi Channel Reverb (MCR) acoustical enhancement system can fulfill all those needs and more by using proprietary software combined with standard components like sound processors, amplifiers and high quality Renkus Heinz loudspeakers.
