Bose's Technical Director in Italy, was able to prove using Bose Modeler

that one system could perform both functions, a tremendous savings for the Vatican.

He used seven Bose Model 25s to create a custom line array. Fifty-six of these arrays were

placed at speaker locations allowed by the Vatican. One of the arrays is shown in Figure 17.

The design was presented with Auditioner and in early 1999 Bose was awarded the project.

During the month of June the system was installed.

Basilica is shown (arrow).

On midnight of December 24, 1999, Mr. Gianotto wrote, "When the notes of the big

musical horns and the silky music of string instruments mixed with the Pope's voice

officially inaugurating the new Holy Year, a miracle happened under the sky of Rome. For

the first time in history every single one of the faithful in each part of the Basilica could

clearly understand every spoken word. And they could enjoy the clarity and full, balanced

tone of the music." Today, the system is considered the reference for audio in places of

worship in Italy. So far fourteen projects have been completed with line arrays in Italy, each

we are told with similar success.

Perhaps most important from a technical perspective on this project was the controlled

vertical dispersion of line arrays. In spite of major doubts expressed by the Vatican's

consultants, the Bose line arrays eliminated the reverberation caused by sound reflecting off

the ceiling and huge dome structure.
