St. Mary’s Cathedral has been a Peoria landmark and religious epicenter for over a century. The cathedral is the central church for the Diocese of Peoria. Mother Theresa visited for a special mass in her honor in December 1995.
The Cathedral is an extremely challenging acoustical space with high ceilings, various hard surfaces, and intricate architectural properties that make intelligible sound reinforcement difficult to integrate. Thompson Electronics Company (TEC) rose to the challenge by designing a system that created great sound quality that ensured the spoken word was heard and understood throughout the sanctuary.
Using the latest in electro-acoustic technology, TEC utilized digitally steerable line array enclosures to transform the audio intelligibility at St. Mary’s Cathedral. These tall, thin columns incorporate several loudspeaker drivers arranged vertically that allow the programmer to steer the output of the loudspeaker to minimize the amount of acoustical energy that reaches the reflective interior sections of the Cathedral.
The result is a highly intelligible sound system with low variance in sound level between front and back seating areas in the Cathedral. The aesthetics of the Cathedral were also preserved with the seamless integration of the speaker components.
