Meyer Sound Speakers Support Papal Mass

At Bicentennial Park near Silao, Mexico, an open-air Mass celebrated by Pope Benedict the XVI gathered a crowd that the Associated Press estimated to reach 350,000 people.

To ensure everybody could hear words and music clearly and to full effect, more than 375 Meyer Sound loudspeakers converged at the site—including 268 MILO line array loudspeakers, which the company estimates may be the most ever deployed for a single event.

The challenge of audio system design was shouldered by Rodrigo López of Mexico City-based consulting firm Zero Phase. His assignment was to provide uniform coverage across a vast, irregularly-shaped area — over a kilometer wide and a half kilometer deep — comprising uneven hillsides, sloped parking lots and open fields.

To augment the main stage MILO arrays, López plotted a system of 40 delay towers laid out along 12 delay lines. Arrays on most towers were configured with five to eight MILO loudspeakers, with some delay lines deploying contingents of 30 M3D and 32 MICA line array loudspeakers.

Pressure was high at an event of this scale. “I had some worries about getting clean, isolated signals out to all the towers,” López said, “but from that point, I was confident the Meyer Sound systems would perform flawlessly. And even with very high afternoon temperatures, there were zero problems.”

“Meyer was one of only two makers with enough suitable loudspeakers available in Mexico, and I did not want to mix manufacturers. And only Meyer could also supply the very highest level of performance and technical support. So it was not hard to make that call.”

The Meyer Sound roster also included 32 700-HP subwoofers, ten UPA-1P loudspeakers for stage foldback and various fills, six MSL-4 loudspeakers for in-fill, and a Galileo loudspeaker management system encompassing 24 Galileo 616 processors. Three SIM 3 audio analyzers were used for system tuning. The event was mixed on DiGiCo SD7 and SD10 consoles.

The flawless audio throughout the event was noted and appreciated by dignitaries in the front VIP section. “Apparently they’d had problems with sound the day before with another system,” said López, “but when they first heard the pope speak, they turned around and gave us big smiles.”

In addition to the papal homily, the day’s program included music from a 70-piece orchestra and a 40-voice youth choir.
